Ultrafast & Ultrasmall

Nature has published a tutorial on current research into the realms of the ultrafast and ultrasmall, including work done here in the J. R. Macdonald Laboratory.

"Their goal is to film events that take place in picoseconds (ps, 10-12 s) or femtoseconds (fs, 10-15 s), with atoms moving mere picometres (a hydrogen atom is roughly 100 pm in diameter). At this resolution, researchers can for the first time directly observe a molecule writhing in slow motion, atomic bonds vibrating and breaking, or even electrons washing back and forth. As these techniques become more mainstream, the pay-offs could be huge."

One of the ideas for using a laser to record a few femtoseconds of a molecule's extremely fast vibrations as it breaks apart came from Kansas State University physicists. Chii-Dong Lin, university distinguished professor of physics, and Anh-Thu Le, research associate professor in James R. Macdonald Laboratory, who are part of an international collaborative project which published in the Oct. 21 issue of Science.

That work was highlighted in a recent JRM Lab feature story. Many more on similar topics are also available.
