TRLFS determined the numbers of change of
NH2O with pH, and NH2O and RE/M oftrivalent lanthanide of Eu(III). These results
suggest that chemical species of lanthanides
and probably actinides dominate thesorption on microbial cells.

Lasers and photonics could enable uniqueapplications in the extreme environments ofInvitedenergy production, subsurface exploration,and environmental assessment. Thesefeatures include contactlesscharacterization, subsurface stimulation, andin-situ photochemistry.

yongxiang hu, Zhaoyan Li
NASA Langley Research Center
Based on the Monte Carlo simulations of
ICESat-2 measurements of 532-nm laser
light propagation in snow, we find that
average lidar backscattering path length
always equals to twice of the snow depth,
and the average path pength - snow depth
relationship is independent of snow sensity,snow grain size and single scattering phasefunction. This snow depth technique isdemonstrated by the ICESat-2
measurements.
