At Microscience 2008, London, 24-26 June, further developments in this extraordinary new technique will be presented in the scientific conference, as well as on show in the free to attend exhibition
Royal Microscopical Society (RMS) President, Professor Mark Rainforth, clarifies the significance of this new technique which is undergoing a quiet revolution: "Until recently it has only been possible to see a projection of atoms, not the individual atomic columns themselves.
"However, we live in exciting times, with literally a revolution in microscopy and a 50 year old dream fulfilled.
"R Feynman, Nobel laureate, predicted the need for aberration-free transmission electron microscopes in 1959 with the words: "It would be very easy to make an analysis of any complicated substance; all one would have to do would be to look at it and see where the atoms are.
"I put this out as a challenge: Is there no way to make the electron microscope more powerful?.
This question has, at last, been answered with a resounding 'yes'.
New aberration-correction lenses allow, for the first time, the position and chemistry of single atomic columns to be directly resolved.
This is leading to many long standing scientific issues and questions being re-visited.
For example, the presence of intentional or unavoidable trace elements in materials can dramatically alter properties, but until the advent of the latest TEM techniques, determination of the trace element location was extremely difficult.
These new microscopy techniques will bring new understanding in the degradation mechanisms in solid oxide fuel cells, a crucial technology for the future of sustainable, low carbon emission and power generation.
Similarly, developing new light weight high strength steels for the transport industries, crucial to reducing green house gas emissions, will require the latest high resolution techniques.
Many other very latest microscopical advances will also be highlighted at this major biennial event organised by the Royal Microscopical Society.
