6. Crossing Membrane Boundaries: Investigating How Heat Energy Moves Across Thin Films Using a computational approach, the team mathematically modeled different types of scattering processes of heat energy in thin films. Through the mathematical modeling, the researchers discovered that limiting factor of the thermal conductivity of a zeolite is the scattering of heat energy due to the arrangement of pores in the zeolite material.

7. Improving Environmentally-Friendly Processes Involving Non-volatile Ionic Liquid Solvents (a.k.a. Salts) Room Temperature Ionic Liquids (RTILs) are being considered as a "green" replacement for less viscous conventional solvents and for carbon dioxide sequestration processes. A ten-fold decrease in ionic liquid viscosity observed with the addition of water (disrupting IL anion-cation coulombic interactions) and an observed increase in viscosity resulting from the addition of lithium salts (enhancing coulombic interactions).

8. One new approach to disinfection was described last spring by researchers from the University of Illinois at Urbana-Champaign. They demonstrated a new class of synthetic antimicrobials that disinfect by inducing negative curvature in bacterial membranes, generating pores.
