The nanoparticles self-assemble into layers one particle thick and into multilayer, self-supporting porous films.
Scientists have identified a new mechanism for the breakdown of the building blocks of cell membranes.

Most ammonia capture is done through the Haber-Bosch (HB) process, an energy-intensive technique used to produce fertilizer that accounts for 1-2% of the world’s annual energy consumption. Columbia engineers report they have recovered ammonia through a new method with a very low level of energy, approx 1/5 of the energy used by HB. And because the technique recycles ammonia in a closed loop, the ammonia can be recaptured for reuse in fertilizer, household cleaners, etc.
