07) What were your personal experiences as a Ph.D. student? Anything interesting? As a Ph.D. student the biggest challenge I had in that country was their main language being Swedish. Even though they allowed us to study in English, when you go to the society, almost no one likes to speak English. Everybody prefers to speak in Swedish. Apart from that, they were quite nice people and the biggest experience I got is from the way that they work. If you just watch them, you feel like they're not doing any work. They come to work at 9:30 am and leave at 3:00 pm. But during that me period, they do things very effec vely. Even those days, there were 16 professors with about 70 Ph.D. students in one 4 storied building and there was one secretary handling all of them and she was above 60 years! That is a good example as to why I don't believe when people say that they do not have enough staff or they do not have enough buildings to do things. 08) What sparked your interest in Nanotechnology? How would you describe your potential in that particular field and what you are involved in right now? When I returned from my PhD In 2006, I was the 9th PhD in the department. Our department wanted to start a research collabora on with a Japanese University. Accordingly I was sent for 3 months to work in one of their labs. I went to Kyushu Ints tute of Technology, Department of Life Science and System Engineering. I got a small project to develop what is called 'Ac ve Polymers'. That was totally different to me since I was doing Distributed Control Systems. This par cular material works as a sensor and also as an actuator, and I had to develop the material. The idea is when you apply an electric poten al, it actuates and also if you bend the material, it generates electricity. A er about one month's effort, I found a method and developed a demonstra on kit to highlight its func onality. A er returning here, I was invited to do a presenta on at the techno conference in 2007. I did the presenta on in front of the Minister of Science and Technology, Ministrial Secretaries and other high ranked officers. Amongst them was the Chairperson of the Na onal Science Founda on. I demonstrated the opera on of the ac ve polymer with the real material in hand. Many did like it and the chairperson asked me to join for the se ng up of the nanotechnology ins tute. There were five of us and we were the first senior scien sts of the Sri Lanka Ins tute of Nanotechnology (SLINTEC) which was a 50:50 public private partnership. During that me I was handling 5 projects in five different areas. We were developing a wearable patch to detect ECG 24*7 and we completed that. That proceeded for the cosme cs, drugs and devices authority's approval a er clinical trials. I also invented a process to develop Carbon nanotubes out of Ceylon vein graphite which is unique for Sri Lanka for which we got a US patent. That was the first patent from the SLINTEC as well. We got another US patent for developing a slow releasing fer lizer. That was the first patent from the Slintech as well. 09) Can you give us an insight into the latest research areas based on Nanotechnology? One is photovoltaic area and the other areas are energy storage where the supercapacitors are there. Supercapacitors became small thanks to nanotechnology. Instead of charge carrying conductors, if you insert nano structured conductors, then that will increase the area dras cally. It is mainly the energy area that I am familiar with but there are sectors like medical, nanorobots etc. IEEE Newsletter University of Peradeniya PAGE 15
