Effective ChargeRediscovered trapping mechanism favours smaller particles

(Nanotechweb.org) A long overlooked aspect of electric field effects on small particles and molecules in fluid environments, dubbed AC electrophoretic (ACEP) phenomena, is in the spotlight thanks to the work of scientists in the US....The group, led by Mark A Reed (Yale University) and Predrag S Krstic (Oak Ridge National Laboratory), has discovered that particles, when placed in a liquid with a spatially non-uniform electric field, experience not only the well known dielectrophoretic (DEP) force due to the polarizability of the particle, but also an electrophoretic (EP) force due to the charge on the particle...6/21

Manhattan Project memos: Roots of secrecy

(Knoxville News Sentinel) A couple of memos from Arthur H. Compton, head of the so-called Metallurgical Laboratory charged with developing the uranium reactors to produce plutonium and the methods to separate it, provide a good sense for what scientists were told at Clinton Labs -- where the Graphite Reactor served as a pilot facility for the plutonium work. Tim Gawne, who's doing research in the archives at Oak Ridge National Laboratory, passed along electronic copies of the declassified memos...6/18
