 The director is coming. Hopefully. I will check now. He might be signed on as Joanna Lacy maybe. So you will give the... The director is joining right now. Yes, I will do. Okay. Okay. Well, sorry for a bit of the delay. So good morning, everyone. Well, good afternoon. Good evening. Wherever you're joining from. Welcome to this first virtual meeting of the African physical society. It's a pleasure to welcome all of you here virtually. My name is Ali Hassan Ali. I'm the local organizer of this activity. I work in the condensed matter group. My area of research is in broadly in the field of atomistic simulations. So this activity was actually supposed to be held physically in Kigali in Rwanda, but unfortunately due to these very trying times that we're in, this is something that we cannot do, but instead we decided to put this activity as a virtual event. So without further ado, I want to introduce a couple of people to say some words. Let me start with the, our director of ICDB, Artish. Are you around? If Artish is not here yet, we could start with Amadou again, the president of the African physical society. Amadou. Thank you. Thank you, Ali. Good morning, everybody. It is a great pleasure for me to be with all of you this morning for the first African physical society virtual meeting. And first of all, I would like to thank ICTP for the support because, you know, this meeting will not be possible without the support of ICTP with all the connections. And also I would like to thank the local organizer, Ali, who have put a tremendous effort to make this happening, to make this possible. This is a really a big challenge. And I see that it is starting very well. And also I would like to say hello to the director of AFR, Professor Omolulu, and also to the secretary, Adriana Pinto, who make all these things also possible. So thank you very much. I think that it is a good start. And I hope that we will be able to make the African physical society a real scientific society which can bring together all the African scientists and to try to contribute to the development of science in Africa, and especially physical science. Once again, I don't want to talk too much. I want to thank especially all the organizer to thank ICTP and Ali, thank you very much. And okay, we can go ahead. Thank you very much, Amadou. I think Atish has joined now. So Atish, could you say a couple of words please? Hi, welcome everybody. It's a pleasure for me to welcome all of you. I wish it could be at ICTP, but okay, this is the new times where we are online. I became the new director of ICTP one year ago, and ICTP has a very important presence in, and also involvement in Africa. And I'm very happy to see, I think many of you might be actually some of you, I'm sure have been students, diploma students are associates of ICTP. We also have a great partnership. Umolulu is here with Eiffel in Rwanda. And in fact, we view our Rwanda as a kind of a hub for all of Africa, even though it is located in Kigali, it can actually has the potential to grow and become a regional center and perhaps we can. So I'm really happy to have this online meeting of all of you. And I wish all the best for this initiative. And thanks Ali for putting it together in this times, COVID times. Thank you very much for joining us. Okay. And so before we start with the scientific program, last word from the director of Eiffel. So good morning everybody. I think for both of us in Africa is morning. So I'll say good morning everybody. And for some other people in the East is probably afternoon at this time. So first I'd like to welcome you virtually to Kigali. If there's anything like that, because virtually you can be in many places at the same time, virtually now you're in Kigali, you're wherever you are, you're in ICTP, you're in different places. So I welcome you to this program. This is the beginning of the AFPS African physical society, international conference and we're having it online for reasons that all of us know. We hope that next year, especially with the development of this new vaccines from Moderna and from Pfizer and maybe from some other groups, we'll be able to come to Kigali and have a meeting next year in Kigali or in 2022 also. We should be able to have a meeting on different things in Kigali. So I wanted to plan to visit Kigali to have this kind of a meeting. So I welcome you to this conference. And in particular, I will say we should work together by listening to talks in this conference and by collaborating together. We should work together for African development and advancement. We should work together to create like new drugs, new medicines, new catalysts that can help in African development and advancement. We should work together to create new energy solutions, new solutions for purification of water. And many other things that we need in Africa, we can work together to do with our scientists, we are researchers and we can, we should work together by collaborating with IFA and with ICTP in different places so that we can have a great network for African development and advancement. So I welcome you again and I thank you for being with us. Thank you. Thank you very much. Okay, so I think we're ready to get to the fun stuff, which is the science. So we have a pretty intense scientific program for the next three days. A bit about the program, it's all online. You've all received it. Some of the things that are being held in parallel jointly with the African signature on light source. And so all those details are online. So please, please take a look at that. Just a reminder that, that please don't confuse the different time zones. So make sure you check that carefully when you're looking at the program. So I think we're ready to get started. So our first speaker today is Jart Kruger from University of Pretoria. So Jart. Yes. Can I say just one, if you want, concerning the meeting for next year? Can we, can we leave it to one of the, the discussion sessions? Okay. Just so that we keep time. Okay. So.
