LBL's Alexandre Chorin and James Sethian Physics folk tunes are cool as Ice

Gene Ice, a researcher at DOE's Oak Ridge National Laboratory and a UT-Battelle corporate fellow, has made his mark in the field of X-ray microdiffraction. The dynamically bent saggital-focusing optics he developed in the 1980s with legendary X-ray scientist Cullie Sparks for Brookhaven Lab's National Synchrotron Light Source were the world's first.

Shewanella oneidensis produced rosettes of iron(II)phosphate in the simulated soil. The bacteria produced these structures without directly contacting the iron oxides. Scientists investigate long-distance bioreduction

The ground beneath our feet is alive with countless microorganisms that go about their lives engaged in transferring electrons to iron oxides. Called “bioreduction,” this microscopic activity changes the oxidation state of iron oxides, affecting its ability to trap contaminants from surrounding soil, sediment and subsurface materials.
