 Και έχουμε εδώ το Θεσσαλονίκη Νανοτεξνολογική Κομφρίνδση. Ε, my name is Argyris Lascarakis, I'm the head of the organic electronics group of the Nanotechnology Lab, LTFN. LTFN, what does it stand for? LTFN stands for Nanotechnology Lab. It's the laboratory for thin films, nanosystems and nanometrology. We have been established in the physics department of the Aristotle University of Thessaloniki since 1991. And we are here after so many years creating cutting-level research on nanoscience, nanotechnology and organic electronics. So, and there's all these cool things we're going to check out. How's the conference so far? The conference was great. Actually, we had a lot of people participating, more than 200 people in the IS4E International Symbol of Flexible Organic Electronics. And we have more than 200 people from 30 countries presenting stuff related to organics and print electronics materials. What's your role in the conference? Actually, I'm one of the organizers and I'm responsible for the organization of the IS4E conference. So that's why we're right here in the center of the exhibition area, right here, the LTFN booth. So it's because a lot of things are happening around this, right? Yes, exactly. We are at the center of the exhibition. The exhibition is a part of the nanotechnology event. The whole event actually that is the umbrella of all the events that we have here in Thessaloniki. IS4E is one of the events. The other is the Nanoscience Nanotechnology Conference and we have also the exhibition plus the summer school that has more than 150 students from all over the world to read experts for Nanoscience Nanotechnology and Organic Electronics. It's like 8 days or 7 days or how long? It's a marathon actually. It's 7 days of conferences and summer schools. And there's still a couple days left? Yeah, yeah. We finished today the IS4E and tomorrow we have the last day of the Nanotechnology Conference and that's Saturday we have the final day of the IS4E summer school. And hi, so who are you? Hi, my name is Krios Kapnopoulos and I'm working as a researcher in the LTFN lab in the Aristotle University of Thessaloniki. And I mostly work with pretty organic electronics. These are some very nice cool stuff that we can show you. This is a semi-transparent organic photovoltaic and this is like a common one but we have some new versions that could be let's say semi-transparent. And also to have some arbitrary shape patterning using laser. And you can have different kind of shapes, different kind of sizes or different kind of colors. Even this is blue, this is green or this is gray. So there's a whole variety of colors or shapes or designs regarding the application that is needed for. So it could go anywhere? On textiles, windows, umbrellas, for sunsets, cars, buildings, greenhouses, your textiles everywhere. There for example there's like a police uniform? Exactly, this is a model of a police uniform in which you have a photovoltaics printed on the backside. So the policeman can charge his radio or his mobile phone. And also this one is a model of the partner who has organic photovoltaics for charging your cell phone or your laptop. Most of the devices are made in this kind of roll-to-roll pilot line that is established in our lab. And we do the video there, right? Yeah, and we have a lot of printing and patterning techniques also quality control. So we have insect printing in the lab. We have slot eye coating, gravity printing, inline laser patterning or quality control using reflectometry, ellipsometry, Rama spectroscopy for the luminescence, eddy current measurements and so on. So you here see how it's a production of these kind of devices and also we have the ability to use some RFIDs or any kind of printing electronics actually can be made in a roll-to-roll line. Okay, so this is an ultra-high vacuum-saber. This is one of the first infrastructures that we have in our technology lab. And this equipment is used for creating innovative thin films, ultra-hard coatings or optical coatings that we can use in a variety of applications. Actually, this is a state-of-the-art system, but we have started from this technology since 2025 years ago. Nice. And we go around here. So this is the second pilot line that we have in the lab. So this is a seat-to-seat pilot line. It's consisting of several gloveboxes in the line. And here we have the ability to produce in mean atmosphere samples up to A4 size. And this is a third pilot line actually, which is an organic vapor-faced position line. It's made for 20x20 glasses and this is made mostly for OLEDs but also for organic photovoltaics. And finally, this is a CVD. A pilot line that has the ability to produce a single-layer or multi-layer graphene on X-6-ing's wave-face. Nice. And if you go back over here one second, you have a bio-printer right here. Yes, this is a unique bio-printer system. With this printer, we can print constructs from which we can start doing experiments with biomaterials. And the target is to create novel biomaterials that we can use for treatment of several issues related to human health. And this unique system gives us the opportunity to create such kind of unique constructs, for example, for ear implants or for the eye or for the makeups. Nice. So it goes from solar technology to ion and nanobio? None of the technology covers all. It covers all disciplines and all applications. And what do you talk about on this one? Yeah. So if you go here, around... one of the many strengths of the nanotechnology lab is optical technology and optical metrology. And here you can see the implementation of optical techniques on production systems for the fabrication of organic and pre-electronics. So as you can see, we have installed optical probes directly in the production line. So during the printing of nanomaterials, we can check in real time the thickness and the optical properties of very thin layers in the order of nanometers over several meters area. In this way we can optimize the process and we can develop nanomaterials and devices which have properties that can be used for commercial applications. And this is the smart line project as factories of the future. We build the factory of the future. This is a European project funded by EU from which we will develop this innovative novel tools for optimization of manufacturing processes. And here we have the CORNE project. What is the open innovation environment? Open innovation environment. This project will connect academic research and industrial editors from all around Europe in order to create an open innovation environment. In this way this partners will exchange information about basic properties of materials by modeling and characterization methods in order to develop novel nanomaterials and devices for organic and create electronics. And actually this builds a community with experts in order to bring them all in contact and create all these innovations in order to transform our future life. And this is an open innovation environment, 11 partners from 6 EU countries. Yes, of course everybody is welcome to participate to the CORNE open innovation environment and access this unique data and materials for organic and electronic devices. Switzerland, Italy, Germany, UK, France, Greece. All right. And over there you are talking about the DIH, Digital Innovation Hub. So what is this about? So now Technology Lab LTFN is a member of the Digital Innovation Hub in Europe that means that we are a center, a hub with several pilot lines and infrastructures that are available to everybody who is interested to perform high-level research or to solve some industrial problems. So for example we can contact us, we can discuss and we can help you solve your problems related to research, technology, industry and materials fabrication by using our facilities and our network of stakeholders. Nice. So there's a lot of collaborations happening here. Yes, exactly. This is the same. This shows some of our facilities and our devices which can be used for services to external entities. So if we sit down here for another second, so what would you say has really happened in this conference? 16 years, a long time it's been happening. There's a lot of smart people that come to this conference, right? From lots of different places and they have lots of networking. What's going to happen now? So every year we see a similar story. People from all around the world gather to the same place in order to exchange ideas about promoting and developing organic, electronic materials and devices. So the technology and the science grew over the last 60 years and together with this growth and have seen several innovations in materials such as two-dimensional materials, nanomaterials, nanoparticles, organic electronic devices of inverted architectures and tandem structures. This time in this IS4A19 and also in the nanotechnology we saw several innovative pieces from people that presented also for perovskite photovoltaics. All of these would be adapted to everyday life in a few years. And all these innovations you can also implement in your labs, right? Of course, of course. So it's all about international collaboration kind of? Exactly. We want to promote international collaboration and our nanotechnology lab is also a hub for connecting people from all around the world. In nanotechnology every year brings together more than 1000 people all together to create this hub and this forum for discussion and exchange of ideas. So the status of the system that you had last year you had the world record on this kind of silver? Yes, actually together with our spin-off company Organic Electronic Technology we were able to hit more than 7.4% for single junction organic photovoltaics which looks like this? Something like that but smaller one, yes. Of course on one square centimeter active area this is much, much bigger. So the efficiency of this kind of this size of device is around about 5.5% nearly. How much do you say? But also we have this one which is very transparent you can see through this and this is mainly used for BIPVs building and integrating in order to use any buildings so we can produce power but also in the same time to absorb a part of the light in order to do some stage or during the hot days like we have here in Greece. But some of the innovation some people talking about 16.8% something like that all these innovations, the new materials you can also integrate? Yes, of course it takes some time because all these high performances are achieved with novellas and materials that can be produced only in very, very small quantities. In order to transfer all these innovations to large scale processes you need first to upscale the materials which takes time. Of course our expertise and our facilities our people are ready to proceed with this transfer but of course this takes time. And what do you think is the future for nanotechnology? Is it going to be solving everything or what's it going to be? I think nanotechnology will provide a revolution to our everyday life and it will change the way that we interact with each other and with the environment. Nature works with nanotechnology with a bottom up approach and this is how we are going to do science from now on.
