 me here and also I have to have me joining the group of the team of new materials here in Glinks. That's a huge pleasure to be here and talk a little bit about my work in the last few years and the title is quite generic and very broad. It's a little bit about my studies on producing Caucasian light bothers that's materials that have a lot of applications you see using like a green chemistry stuff, green chemistry approach. So basically as I organize the presentation on several topics I start with my introduction and of course just talk a little bit about me and I'm a physicist and I will have my bachelor of 2009 and also do my master's in physics with some conductor physics using spectroscopy basically running spectroscopy and after I moved to Jordan office 2001 and since then I'm working with this uh mechanochemistry approach basically called mechanical oil, ball milling, different names that you see that people trying to join and at the moment I'm a professor at the Department of Physics at the University of Santa Catarina. I thank you very much for people that allowed me to get this setbacks from here in Europe. Professor Dinh here from Max Planck Institute of South States Research and Professor Elizabeth for kindness and also a lot of support and discussion on science and so on. And the home institution I just wish to show some of the my website where I used to publish the recent papers and after pandemics of course there's some virtual meeting room that you can chat and discuss, share information and also very useful to make contact and do start collaboration with people around there's some links for different of departments of institution also something related to the secretory nation that I will show you later and we have also in the graduate program that's very tough. You have a lot of people work in different areas of physics most 70 people in the department and the graduate program is a little less but people are very active on that so physics physics theoretical and also solid state that's my area. And just to have you a taste of where I live that's this is a Brazilian math here you can see the Santa Catarina state that's one of the the smallest states in but contributes a large part of the GDP of the country there is also a very good place to live you can see by the facts here that's the lowest economic inequality you can see and also something that related that with the the colony also they have a lot of immigrations from immigrants from Europe even Sweden there's some people from Sweden that moved there in the 9th century and we have like a very nice place landscape you also have some islands that you can find some weather like some snow sometimes and also in the very active industry and probably the electric motors you have heard about the baggy and the compressors also the largest companies in the world that works with this and that's very interesting that's one of the states that's in the capital that's what an office that's big part of this island and then the little part of complex and where they figured out university is hosted at something that you have a large number of students like 32,000 students like you have some expansion the amount before that's about 12 years ago there is an expansion that more campus of bigger universities spread out by the state so give your pretense for students for different regions of the the state and you are basically the middle of uh so that's an estate that was more traditional on different areas like agricultural and have a lot of course some contribution on the industrial point of view and also exportation of some agricultural products so here's a some pictures of my favorite place in the island here's the uh Laguinha the last one of the most uh so say there is different kind of places that you go if you like to travel you go to the model beach that people like to surf and here's more wide place that I prefer that's this is a small island that's about 32 islands in turn of the big one we have some lagoon that's really pleasant place and here is the more the downtown the center where the physical department is located here you see the buildings of the teams department and math mats in between here you have the fraction lab and you show some pictures to you and here just to start to show a little of the infrastructure I have uh mountains in my 20 years and like 16 years work as a professor with that we got some funds got those infrastructure and basically the equipment are related to the spectroscopy with the Raman we have some color in the tree some very nice device that you can assume it can is amounts of Raman and and calorimetry and also something related with the high pressure and I will show in the tail that's the room where the students work with computers and here's the volume with the meal that I use shake the meal here you can see the small device with the Raman spectroscopy here zoom from the the uh microscope nearby the the Lincoln DSC here you can see it's a machine to make holes and to prepare the samples to put between those beautiful diamonds as you can see over here and this is very special tool I did my PhD in in Paris uh learning about this high pressure setup and how to perform those kind of uh high pressure experiments it's very useful and in the basics of physics you can determine some phase transition in the question of state as well so I'm supervising this lab this lab is equipped with the uh powder diffuser meter you have a lot of access a lot of equipment that it can make do some in-seat to high temperature up to uh 600 600 degrees having also the last and the best thing that I got before pandemics that's the robot army with this you work a lot during all the restrictions to access the lab that was amazing to have those two because the students went over there prepared samples and I remotely could get some uh uh data to retrieve the restrictions of pandemics and here also we have some uh mute user oscillates the all I'm very big fan of mute user uh infrastructure that's that's one of the gold machines which is up 50 ms physical first measurement systems very nice nine-time lab in a high field you can have and yes and that's small two but for more regular measurements and you have also a facility that's more uh uh need for all people on the university there's a central lab for micro microscopic uh the turn microsofty and here you can see about 800 kilometers from sure and up to that over here you can find our our single or our four generation machine 3gb very similar that max four of course max four has an extra ring that's a more sophisticated way to to to put the the electrons up on the storage ring here you use some booster and you have also a very nice moment to have seen about 10 bean lines in the third call open to the users so it's a very good convenience and that's one of the reasons I'm here to sharing the information and to learn more about the four generation machine since max four was open for was the pioneer on this and it's it's important to say that our synchrony is inside the more big project that's a national center of research and energy and materials that is is also composed by some bios biosensors lab we have also a bio renewable renewable materials lab and also something related with nanotechnology and we have a lot of a calls open at the moment for people that would like to do some on nanoscience using the microscope the powerful infrastructure that they have over there that's a very interesting here some picture of my student that was finishing his PhD recently about years ago the oops sorry the infrastructure is quite cool I'm so sorry so it's quite good you see some the detectors the robot arm that make possible to change automatically a lot of samples and that's just to say that's our old source that has as an old source that was now turned off because you need more energy to run the new machine in the series and yes the name of the the source here is one of collaborators that work with cement that one good collaborations here is what the new beam line Emma I'm very glad to to contribute with the old those infrastructure that they have on on extreme conditions I start to write proposals in 2004 to do high pressure on our secret and nowadays they have like a perfect setup for for external conditions with the high magnet field and a lot of diamond and you'll see how I'm very glad to to promote these facilities because sometimes even people in Brazil doesn't know exactly what it has well the title is mentioned about calcutinides if you see calcutinides are all the elements of this column 16 but in general it's more what much more use it for sulfides and selenides until it rises calcutinide term and I'm used to play with some traditional metals and then also doing some scent conducting stuff like valium selenide valium telluride indian selenides and a lot of tree six or say and recently I turned my my research to to explore more some like a bit smooth tellurides and selenides and anti-monium is also one of topping that make possible and you see soon that's very useful for put the condition that that's conditions for some chemical patients and here just to get gave you some uh overview you see some growing the term of calcutinides research done in scopes and see different areas my pure science and physics engineer the most used in the but we have also some applications in biochemistry and something about on computer science and chemistry also and you see that there's so to say hot talk at the moment a lot of people do and work on this kind of materials and here you see a nice review that was mentioned also it's a quite bold 2017 but mentioned with some of materials that we have produced in the university or something that in here saw the list of some applications you have just basically this this paper is mainly focused on sulfide and selenides you can see some of the rides over here and see the the detectors you use in synchrotron it's very common you have this cannon to the right so uh here you see thermoelectrics and copper sulfides and chromium sulfide there's something also uh mentioned here there's just some pictures of the setup this is mule that you see picture four that's a kind of shaker mule that's many different kind of mule that you can do my kind of chemistry and this is the one that I use you you you classify these as a high energy with shaker mule and here's basically picture of the stainless steel jars with the balls that's also stainless steel we also put the the reactants in then some uh protective a hemisphere like argon but it just looks like simple but if you see you have a look at the ball tan variables to adjust and to test and to play with that's something very exciting and here is just something that you can see is running you have some like a eight movement of this and in the mandatory website you can see this little move just shortly so before coming I have uh after pandemic students and that's one of the points that I look for so I come back to the lab and I prepare like 29 samples to come to Europe and have something to play with that's something that I I was not missing too much because go back to the lab so it's better to advise the students anyway uh the main idea is also allies to promote some knowing to liberal reaction that's very exciting because you can find some new compounds that's one thing that I'm very glad to see and my pj student that was showing up clearly was very happy and of course who worked a hard and worked a lot to find new crystal in place so this way to to make the synthesis a way that you can find different things that it was not predicted in the phase diagrams that's really exciting of course there are some real problems on the combinations oxygen and also the building tools we've collaborated but also there's some very exciting things explaining how the reaction is taking that some melting drive uh uh routes that you can verify then that's very nice paper here uh in nature materials that show up like uh some predictions that some materials that wasn't left of this uh diagonals that's a diagonal corresponding to the meal that you have there's some different kind of meals you even can project some some possible uh driving metal driving melting mechanism that could be how that happened it's not more evident and then the prediction that would say that you can have that by hand let's see if you use in three terms and expect if you can see here at three because it's much less probable to have this kind of impact so this right was used as prototype to pass this mechanism this theory and that's very exciting something that I could call so extra motivations here as I said there's something that you can explore extreme conditions also to verify if these materials are stable or if the phase transitions are the same as you have on both materials or on films on different kind of forms of the material if these move through the rise for example that I'm exploring so you can do this also using temperature and the technological applications I mentioned a lot off of them electrics but then you see later on that you can use these as sensors on electric chemistry it's something very exciting in collaboration with my colleagues on into the park so talk about application I like to show this and then to show how the materials can match and other particles and nanotubes and super materials can match as in the in the area of functional materials and there's also this triangle is the step triad of this very this is more class one when you have those functional materials that's someone that you design to some but achieve some applications so we have characterization in the middle and possessing that's mechanical chemistry it's also something that does hetero feeding that information nowadays of course you have like a big silicon research that people do we do a lot of assimilation so it's a more modern way that you get information and all computational skills and infrastructure to get this more dynamics and more like say modern way to to see and to to prevail something here's something very short just to mention something on nanomaterials what means nano what how people see nano of course there is something related that one of the mentions of material at least have something about 100 nanometers but I have I like this definition that nanomaterials have different preference compared to the large particles so see this is most on the sense on the view of the functional materials on application when an engineer point of view there is something on the European Union Observatory defines I like to use these also that's laser force proposed use that's this black solid circles represent the nanocrystalline domains and here have like something more or less like book crystalline behavior you have these empty circles is the interfacial component they call this interpretation and here you can see some left infraction here height and distribution image that suppose that this borders these interfaces are quite complicated and here is some illustration that this solid or more dark circles could give you for x-ray fraction like some bright peaks very sharp or more or less sharp graphics depends on the size of the crystalline main if there is something that is amorphous you have parking like this you can store a lot of these with total scattering yeah there's something that I also haven't worked in the last years and here's is the interpretation that you can have from the interfacial company there's something that's impossible to to to define and to see that with x-ray fraction so that's why it needs a lot of experimental tools to access information from this monomaterial, monostructure, monoprystalline materials and here there's a classical list of the thinker's methods that you can see cvd you can think about the position time on the position hydrothermal concentrates it's very popular at moments very interesting solvotermal and a laser ablation you have some combustion that's microwave thinker that's something very uh like mill and gas phase so gel and of course you have also some natural as you saw aerosols and some new team here here in the links explore all this and that's more or less related with those two ways to see the nanomaterials like button up and top down so you just mill it's very versatile too because you can get the bulk material like a bismuth allurean phase powder that you buy and both form and can mill it and reach like a small surface small crystalline domain or so small crystallite so of course that's as small are the crystalline domain biggest are the surface air they activate the material and also you can do this button up that's more exciting that's what i used to do so we use like high purity elemental powers and you mix it and with the mechanical energy that's the beginning 20 years ago i expect to have more or less like amorphous that's more the goal of my supervisor at moment that was to work with the radial distribution function that he was expert on using syncope we use a lot of syncope to have this large tube range data but we have a good surprise find like some aerosilinites it was one of the first alloys that i sympathize with and still being using and showing some applications and if you think about milling our this mechanical approach you see that it's matched with the civilization history that's something that we use for all day life and something else so very useful in the industry especially mining stuff of course so you can see some examples on from a certain industry who uses a lot and then ceramics a lot of applications and here's the time that's something to send out papers that the guys started to call this like a mechanical alloying and was most concerning to to to spread some etrin oxide on this metal alloys so make these super alloys mainly applications on our industry these turbines also the the navigation and the spatial spacecraft and planes and something that was the odd yes like oxide dispersion super alloys and also you you see something very interesting to explore on the kind of things there is also an extrusion so we can do this by shaker mill and the collisions after all but you can use some extrusion that's very interesting way to to play with this and also have different markers here is some nickel base of the voice one of the goals to to my my first system that I choose iron selecting for example you see that they have very large melting points so mechanical route think this is also a very clever way to get those alloys without using a lot of energy you don't need to to melt the iron for example more than 1000 degrees and then selenium would be like a gas it would be very complicated stuff you need to seal those powders and and then falls and something that's very important and very easy to get on the mill you can expand also the solid solutions or sometimes some emissive all metals can be put together and then make some different like a more full space is also and of course then on the crystal and the so-called materials so mechanical line is in fact mechanical chemistry so there's a you know the technology on the literature you see there is something very not confusing but there is a different ways and even recent papers trying to put all together and to show that they also engineering I would like to say the three book chemistry be the chemistry of the surface also related with a lot of this mechanical process and this is the first time that was registered something that was a liquid metal obtained with swath America it's very special way to get that as I told you that's look like simple stuff but there's a very sometimes details on the recipe to get the final result and that was one of the the disciples of and exactly what's one of the first guided long run and go and here you see some the evolution of stations of these terms I need some review recently it looks more or less like this in the publication and the different terms you see it here I didn't include tribology but there is also a talk and also there is some nice comments or nice publication of 2019 about that how these innovations could be like a changing words technique and after that you can see a lot of oh even before you see some something on the nanoparticles technology something on pharmaceuticals and you see some commercial drugs our cell and the pharmacies are using those kind of approach here you see some reviews about that and also very interesting and very exciting thing on chemistry at the moment that's something that you can have some in groups you can use this for this molecular synthesis that's very nice people doing this in gases make real reactions with gases you see some reviews on those books that dedicated to this and mainly called as I mentioned on some green chemistry so it is very recognized as a good good way to get some of those materials and this is very nice the beginning January I like the title of the paper that's that more phylozontal way that touch or not touch showing that the influence it is very sensitive if someone touched the balls they have some different reactions on polymorphous or carbonyl decline that's one of the drugs that was and they did like very systematically I like to follow the solution so actually there's a lot of innovation on this book and just to summary that's not only kind of chemistry have implications of many different areas I used to play with the some collaborators that arrived to us for x-ray infection in general but I always try oh let's try to mule something that they did try to put some high energy for so to see how your material could move or change and of course I would like to share with you a little or more specific on the applications of thermoelectricity and you see people playing with this also for portable tags you see some larger skulls industrial scales setups that are put in the practicing that's very nice this is one also more related also with the milling and also depressing also something very important to get those good figure of merits for these materials I explained about figure of merit about means but how good are the thermoelectricities and you see this setup was proposed in Korea that's very nice one and you see that very the way to scale up also it's a number of transfers using these mechanical chemistry routes and to characterize I always consider that they had all four characterization is that x-ray infection to see the thing does itself to see the reaction to see the contamination and also to explore more and more the microstructure so to say I mentioned this is the crystal size the microstrain and isotropy is something like very nice to explore and also imaging this topography tomography that you can do on those for generations simple terms it's something related with the head of this chart I like to use and also chemical analysis also direct to view of the morphology of course that you probably you go about the TEM the transmission led to microscopy you see the size you can determine the size and the shape of the nanoparkos but statistically you just use to see very very small fraction of percent so x-ray and this approach that you used to get from line building up practice is much more representative and also terminal analysis very useful you can complement and spectroscopy you're using x-rays it's also extremely using and very excited to play with the something that I learned here in links with amazing covers and main centers to make a lot of images with sounds like like sacks image that's very exciting to try this I'll see you so maybe come back here to max four and also electrical and magneto and transport in general it's very very important characterization special especially on terminal conductivity that you connect the goals with the electrical transport it's something very interesting and the spectroscopy Raman I that's very versatile technique I love to play with is of course that was the first contact with it research was using Raman and that's very nice also the breach that it can have between the crystallography and the spectroscopy using DFT and some the theoretical approach that's really really amazing and here just a schematic to show me like a fathered pattern so we have to test the angle and then if you have some large crystalline domain you have sharp peaks if that small crystalline domain you have broad peaks and if between you have probably some contributions on the background in general people use just to get the broadening use sometimes I'm very upset with seeing this getting the we're not considering instrumental contribution until I'm saying and get the average of precise so they are sub estimating a lot of the microstructure so what I do in the last 20 years was to improve my skills and also train people to see this more deep make this peak profile modeling more seriously using DFT and also for the scattering and for these mainly daughter scattering is synchronized metaphoric and very important that's what why also I'm here and very glad also to start to look this with some neutral data and mentioned something that's very happy to be here at the moment and right place right moment and just to I don't know how long I think but I it's hard to show some of the results that one of the applications of this nicotil rights and I mentioned I use a lot of of these topogenized clothing coloring and nickel and applications was very exciting with people from Kim's department that professor Joss was one of my partners and Duane was a PhD student at the moment so you produce very cheap and very easy way to determine some molecules some biomolecules and then also very exciting to play with those that's lines and also like lines that's some easy way to and this work is also very interesting was one of the same now works use also nicotil rights you have this single can is that looking for the action of these two biomolecules very very important on biomedicine and a lot of diagnosis and also to control a lot of things and instead of applications you always look at for the morphology the micro super also from a magnetic behavior of these materials and to try to understand the mechanism that drives this nice behavior of this very ship and very easy way to prepare these sensors and here is as I mentioned that I would tell you I would sell a line was the first 2002 that was my first paper production on my PhD and after that my student more recently started to review and to try to find a specific crystalline phase that was mentioned and was named that a superconductor one that's a lot of by the stability of stable are those is this product and here you see that I mentioned that the synchro the division and I decided to put a little bit more you did not see clearly the superconductor position but maybe you can see something on the transport and you have a lot of probably possible problems to do not see superconductor related with the contacts and so on the experiment and measuring itself and modeling when you talk about modeling the micro super I love to show this cooperation that people from Italy to believe who is one of those guys and that's the last on the slide source that develop a very clever way to to to deal with the micro structure using total scattering so they have a very nice protocols to get the data collect data for pillars and scattering a lot of very clever way to see that's a such state like that different way than with both methods to see and you can see a lot of contributions for anomalous scattering and more to say the shoes is kept in that state and this system special I don't know the room you see that you find here and maybe the fight by a big diagram shows that you have no rich I don't face preview on the face diagram and the compound you will discover so to say more on this region that's like a some reporting may doubt that show that could be a very rich I don't tell right face but it's not the elbow and here we did a lot of measurements using different and tuning the composition very carefully and also do the micro structure characterization considering this micro strain in a way that you can see some isotropic effect here you see that's a lot of misspeaking high angle IQ bright peaks if you put on strain at the worst if you try to see some micro strain in the basal plane you still improve you start to improve and if you put some in the basal micro the strain and you see some anisotropy on the micro strain so that's one of the like most like efforts to do the micro super characterization use the did we see approach that's pedernica was in Denmark at the time how offers diversity so she did an amazing job on on this characterization and also you compliment as I mentioned you have access to do some high-temperature in c2 x-ray pressure magnets and they did that at the lab it looks in the department also you did that at synchro from the ubx source at the time so you propose also some phase positions for this male phase so that's one of the contributions that I like to show this guy is one of the right students I have they named his master with me and now he's in here in Europe in Italy and he was very dedicated to show and to learn much more on instrument how the instrumentation can influence on the data so you see different source the detector the sample and the optics the different detectors if you add one coordinator how to play with this we have here a typical butter and here you have this way to see the peak profiling more deeply and you'll have like a lot of convolution of different equations are different forms to to deal with those source emission instrument file of course that you want to see about they want to learn about the sample itself but you need to understand how the experiment is done so I love instrumentation I see a lot of physics behind this and that's why I like to play with the students myself prepare this just to show how convolution of two different you know we have like a hat very popular kind of convolution use and also something with the explanation okay and there is some very popular way to call this is the fundamental parameters approach that includes most here you can see graphically or more the usual approach of this contribution of the source here's the contributions for the instrument itself the half you can see more or less the final x-ray source with you can see some contribution of the optics here you can play with the two tails you can have some standard measurements and see the tail of the peak profiling we see exactly something like this and some shoulder a very flat shoulder that's very interesting you can model all this but of course as I mentioned you more the interesting on the micro structure of the source to get the intensity of the peak profile you have to come with a lot of information and this is not nil something than the 1979 the kluge aleksander book it's my favorite one to see all this contribution but of course this is all implemented on these nil uh suites like topas and I said it's a big final topas and work with the all this guy that one of those guys that have pretty latched that some demo and very uh updates versions of topas and here a little bit of the the system that myself worked with it's more than just a metal like the bulk of the luring the explorers the back of phase it's also very dedicated to to analyze the influence of knife you have no knife you have a lot of air scattering it's very difficult to to identify some impurities like even iron the iron comes from the really tools and it's very dedicated it's very obsessive to get as better as possible so we get like a final product more than 90% of this cobalt phase and also the approach of the micro structure here of course use like did by share or share equation of course as always there but it was more dedicated on seeing something that we are uh mentioned that is uh something on this ability with this ability of course but also the the innovation of Marcelo and his contributions is mainly on seeing the possibility to modeling the size as an and it's not to be uh uh size of the crystallite so it's modeling the shape of the crystallites and he went deep on this uh calculations on this modeling and as a result you can see some improvements on the analysis of course improvements are very very you know you need to to be very very careful on the measurements so that's why again I mentioned that the synchronization is very mandatory you got very high quality data and here you can see almost no noise and he see he saw some improvements and then modeling something from needs of repeat of these cobalt rights here make the knowledge apparently different reference and you see like a difference is on the distance between two room and it's more or less resuming than and summary and a lot of publications using this master work and for the end I have also thermal electricity as a motivation to work with this myth move to right but of course there is a different applications and very fancy topics that's the topological isolators that have a lot of these moving rights of course they use more careful single crystals and so on to to to explore those kind of images and narpex I saw very beautiful images from from the dispersion the transistor and also we have some superconductivity on some things that are induced by pressure and string turning materials that's very very nice to go with why thermodynamics there's more you know I like not only to use green chemistry but see applications that of course could contribute on the on the use of some source of energy that you saw in many talks here doing my stay here in links people showing that the heat is something some energy that you you release and you don't use and you do that probably in the industry in the environment itself so thermodynamics is something that not new but like to centuries people know about the effects but of course there's some bottlenecks that's maybe related with the material science and that there's some very good applications and here you can see I like to explore a little about the heat and see the prototype the guy from two centuries ago inspired by our study experiments he defined it and he saw that the compass also sensitized by this current that was transported by the from the feet to the cold fingers let's say and as I mentioned 200 years before you are still seeing progress and the left device the challenges you have then that these moves to the right was discovered by by seeback but it's still being applied and induced from the commercial applications you can see the different geometries to explore like a harvesting it's very popular even some automobile industry use yet that for example even for comfort in your seats and the very fancy cars you have some eaters that are using for thermal energy devices but there is some very fancy very futuristic and there's people also consider that the artificial intelligence will be take energy itself because one of the most related energy from the IT machines is heat so he can recover the and the autonomous on it it's like a mirror right we're afraid to be very indefinite from this and here's I like the cd because he is trying to it's efficient of the machines the thermal dynamics based on the none that we can apply this also and here's the zt that period of merit that I showed before and here's seeback coefficient that that you name it in amelioration seeback but you have also some transport of the electrons and also the thermal conductivity that you have some of the front and let's contribution the let's contribution is some part where it can play with and then the structuring is mainly to play with the the increasing of this let's contribution to to keep the heat and the cold and the and the and the high temperature regions separately you don't you don't want to and thermal energy performance of the devices you need to keep both fights in different temperatures you need for it any machine kind of dynamics you see that you have some high temperature reservoir and then cold and here's you see some time evolution since the 1960s and here you see the gap the gap is because the people don't believe that it can improve more the efficiency but nowadays you see the boom of interesting a lot of people work with and you see that recently many different systems also use it not only this move the right and here you see some nice paper that was mainly resuming and what I mentioned that we need to play with the non-stricting to improve the thermal conductivity and creates the change in the difference in temperature uh condition that's not so here is two systems that I understood at the moment see the phase diagram it's very rich phase diagram and this move coloring I focus on these two compositions and here is see the most popular so the approach or the innovation of my recent work is try to see in different lives or different phase what's possible to to improve in terms of of of the efficient of the analytics and you see it's very complicated system in terms of crystallography because all the phases can see as this ethnically adaptive series of these blocks you can have a lot of stacking of these move layers and this move to the room so it was represented here as this empty rectangle it's in this move to and this shall break the candle in the blocks with the hill right so different phase with different compositions have almost the same structure the same trigonal structure so the four x-ray infection is very complicated to separate it into discriminated between this phase this is just calculated patterns from the database but here you can see our results and also point out one of the problems because the theorem is very the update it's very sensitive to to air so you use and you make some tests to use some theorem that was not so pure so to say and in the case of this this case is this move that's the same you have quite large quantity of oxides and here's the room I'm sorry and see you have one of the possibilities not to use as raw material to use granular source the granular source would say less contamination by oxides and most interesting yet even if we start some oxide when we have less than one hour of mailing you've got the reaction so we started with this move with little oxide it's like in fillery with a lot of oxides but after less than one hour you mainly get only this move in tellurium of course there is some small peaks especially on this this sample but you've got the same composition but now using granular tellurium you almost see only the dismoving tellurium phase so it's very sensitive to the contaminations and here I'm exploring more the rich side of the phase diagram that's why you can have some these with two tellurium phase that's if you see then the patterns are very difficult to discriminate between them and just to to show you a little bit how my samples look like especially because the titanation of all the samples are smaller but you can see huge particles in the cm you can do this chemical analysis you see of course a little contamination of oxygen you see some contamination from iron that sometimes is more specific in some grains that's something that's very interesting and also the shape of the more close looking more close together with this disease is something that I expected something that's very declamorated with some manual domains of course but surprisingly on the study where we start to see some beautiful structures very very well-shaped like more or less like a round shape here you see this instagram like a mean size of 25 millimeters and like quite broad of course size solution but you can see also very beautiful particles nanoparticles you see the side over here it's very more layered in almost a single layer and that's very interesting for seeing this kind of material so there's many different ways to explore and about perspectives so recently very soon you will have some real-time measurements that here the picture of the meal that in the SRF that's 2010 what mountain and to follow in real-time the reaction here is a different setup you can see in the SRS and we can also use different ways to explore and to reach and to follow the chemical reactions with x-rays and here is our proposal that was inspired on this paper you can see for hard materials that you need also the bill in the beam line you can need there you need of course a lot of plucks hard x-rays in my case and you need some the widows the vessels the vessels are cut here to allow the x-ray bypass and here some adaptations of the meal that you have and there's it there's some nice calculations on this paper showing the influence even though the the shape of the arms of the shakers are very nice and Claudia was my collaborator and very glad to have access to to his setup her setup and his development on this and now you see for these hard materials is mandatory to have this metal ring so soon we will go myself will join me for all the skype also getting support and of course for the batman obviously very important okay i take long i don't know how long i talk about but i'm good anyway i have some new perspectives that i'm very excited with the news when you listen from the zeal we have like uh in july we've got announced that something that will put some money on on on multi-purpose reactor we have some project that's quite a long time ago like 15 years ago and recently with this government changing you have a lot of good news coming from the zeal and you have this related to these investments on science and technology and here you can see that cities are synchronized that was miracle that during the pandemic all the crisis the public crisis the guys was managing the the budget for seriously what's open and now we will be have a lot of a little more inputs to put more v-lines accessible to the users and here you see collaborations you know argentina it's not also in that good moment in the economy but they are inaugurating some reactor that will be all more or less like our third megawatts open pool reactor that will be open in argentina and there's some collaboration that will be done and here some you see how long the project are running for and now our reactors multi-proposal may be caused by the azocops and for medicine in brazil it's very permanent report all those very expensive raw materials to to diagnose it so one of the proposals of the reactor our reactor is to implement this and then at the moment you have all of this budget to make some you know to put the project in the paper like that and here more recently they got even the plan the place where they would like to to put the lab and you see here the synchrotone the bottom 35 kilometers from is some policy so the idea is more or less like you have here in lume that's amazing you have so complementary source for an x-ray and neutrons and here just showing how the some reactors i know i learned here one of the schools in arctic schools and sweden school on neutrons that you are supposed to but that's maybe could open some opportunity to brazil to keep this collaboration and that's why i would like to be touched lakes its s you know people that could be very very important on the development and the human research you know training and so on brazil it's almost quite good to get this we have the for our crucial uranium so we can get the fuel on our plants to purify uranium in Brazil so that's very uh so to say the project would be also implemented with the people even with no much budget a lot of people do correct calculations planning the instrumentation because of course you have the source you need to play and you have budget to to to build the instruments to do the fraction they're going to scatter and so on i was so intense and the same moment that was announced this and people from new k there's some Brazilian on izes and that's the key so they start this this wet nurse and there's two series in august and september i attend one of them and the series two they asked for people to show up what they are planning to do with the neutrons and i was very glad to learn a lot of hearing links with the school with the water in august so here the chat we discussed with people and they were very kind and they motivate me to look for and i start to try to understand a little bit more how i can apply some inelastic scattering to see all those effects on this this with the right so those papers show clearly and even off the crystal point of view we get more cube range more intense peaks of the this compounds that could be very useful to discriminate between the phase that i have and also to give you more information to do the micro supermodel and of course you can access the time of conductivity with the neutrons that's in more efficient way and here just to illustrate that here is are they calculated patterns of different phase that i have in my samples with the x-rays but if you use neutrons you see again a lot of information in the high cube range that's on expectations so more good news and we have some phone people in the UK are fine financing we have a phone room for three years that we will give some Brazilians opportunity to go to eyes and perform the the research so i apply two proposals one for Mary that the inelastic scattering gene is the fraction so that's very exciting to be involved with this i don't know how possible it would be but i might in the future i would like to have these also why not Brazilian access to the SS whatnot i come with you guys i hope that you can support me and thank you thank you very much for your attention and it's to hear me sorry if it's too late a little time but that is thank you
