Johnson, III, along with Dr. Stephen Roberson (FAMU doctorate, Fall 2006), and Dr. Charlemagne Akpovo of FAMU have found first evidence of turbulent behavior in ionized gases which have a lifetime of less than 100 nanoseconds. (A nanosecond is one thousandth of one millionth of one second.) Laser induced plasmas in Nitrogen, Argon, Xenon, Neon and Krypton were studied using measuring speeds at rates in excess of 10 x109 per second. Turbulent flow fluctuations which influence mixing on such short time scales will cause dramatic changes in applications such as ion implantation in semiconductors. Such fluctuations will drastically change the reaction dynamics in the synthesis of new nano-materials. Furthermore, computations and modeling for the molecular dynamics in nanotechnology must now include new physics driven by turbulence in order to correctly predict the manufacturing... http://www.nsbp.org/en/rel/84/ noemail@nsbp.org Fri, 18 Jan 2008 22:00:00 GMT
