Nanotechnology plays an important role in removing toxic chemicals found in the soil. Currently more than 70 Environmental Protection Agency (EPA) Superfund sites are using or testing nanoparticles to remove or degrade environmental contaminants. One of these — nano-zero-valent iron — is widely used, though its effect on organisms has not been examined. In a…

With a new technique for manufacturing single-layer organic polymer solar cells, scientists at UC Santa Barbara and three other universities might very well move organic photovoltaics into a whole new generation of wearable devices and enable small-scale distributed power generation. The simple doping solution-based process involves briefly immersing organic semiconductor films in a solution at…
