Nanotechnology and ICT



when is big small and small big and smaller bigger again we live in a world where we need to create greater and greater data storage capacity and mastering that data storage issue can be hugely enabled by the use of nanotechnology everything in the world is getting much much smaller and of course nanoscale is vital to kind of help us continue with this technology we can't go any further is that everything has to have a dimension is size associated with it and we can't make things smaller but nanotechnology offers a new path to take miniaturization to the next level ten years ago you would get an mp3 player that would have a certain amount of space on it you might only have a few megabytes and now you can routinely get an mp3 player or twenty two gigabytes so in the space of 10 years we've had to tears and times more space for our entities to pen these devices so the advantage of having a higher density data storage medium would be that you could store more information in a much smaller space so that your iPods other two mobile phone can store an awful lot more information than it currently does the data storage issue is influenced and governed by a recognized principle called Moore's Law Moore's law states we will double the number of transistors on a computer chip every two years that really means make them smaller Moore's laws on scalability reducing everything getting twice as much in the same area every two years these things are going to keep getting smaller we're going to keep packing more and more transistors and hence giving more and more punch to electronic devices so that they'll be able to do things that now we can only imagine so knowledge technology in essence at least in the microelectronic industry is just the natural evolution from micro technology to nanotechnology and with constant development in the nanotechnology world how would greater data storage be achieved magnetism which is how memory is created has already been vastly improved and its devices miniaturized by nanotechnology you might have thought that magnetism was something which was done and dusted 50 years ago with the horseshoe magnets that used to see but in fact nothing could be further from the truth magnetism is is something which is developing very fast it's at the cutting edge of information technology and if you look at your computer for example your computer and you have billions of magnets in your computer we're looking at magnetic nano wires so these are very very thin stripes of magnetic materials like iron or cobalt or nickel and the nice thing about the Nano is that we grow in our lab is that they're in astana so parallel rolls almost like a very long zebra crossing these could be used for a very high density data storage medium maybe it could be the next generation of hard drives our data storage our world is constantly changing bringing with the revolutions in technology that can seem fanciful but in fact many are almost with us already the industrial world needs to be ahead of its game in responding to these new technologies yes let me give you a very good example about four and a half years ago Hewlett Packard came to us and wants us to address the possibility was to helping them develop electronic paper and we were wondering why but it became clear to us in no short period of time at all the Hewlett Packard makes their money from actually selling toner and if conventional paper was to disappear they would actually be on a business so if you could imagine having a piece of plastic and on that plastic our nano sized electronics that allow it to act as a display to show off moving pictures show of text but it's not ink on paper it's an electronic display just like your TV screen or your computer monitor and that could be rolled up folded put in your back pocket oh it's be updated by Wi-Fi you could read the internet on it you could read books read newspapers except it's not a rigid thing like an iPad or akin it's a piece of paper like plastic and this is a paper and some companies think this is really the future if you've seen Avatar in the command center of the the Marines they have surveillance with wrap around screams displaying maps and all sort of information so that's one of the things that people want to be able to do is make transparent screens but still are able to show images new electronic materials and new processes are already available the logical next steps would be to integrate them into how we live and explore their commercial applications globally this huge rush to investigate this really really exciting area so that as scientists and businessmen can exploit the really interesting findings and knowledge that scientists gain carbon nanotubes are a great example of a material which perform fantastically in a research laboratory they conduct electricity beautifully for example and we can take advantage of that in our chip production so my project is working on how one might take advantage of carbon nanotubes in an industrial process can we make this material manufacturable three years ago we weren't even players we're now world's leaders in making these materials not a technology some people might argue it's just good old-fashioned physics in chemistry it didn't just arrive today people have been working in physics and chemistry for a long time the scientific challenges that face us in the next 10 years are so diverse that we need all the help we can get I certainly believe it's gonna make everything much better much faster much stronger it's the way forward
