Recovering Raw Materials for Green Technologies

Engineering researchers from the University of Leeds have discovered how to recover significant quantities of rare-earth oxides, present in titanium dioxide minerals. Rare-earth oxides are useful in many applications, such as the manufacture of wind turbines, energy-efficient lighting, and hybrid and electric cars.

New Nano-Material Could Revolutionize Solar Panels and Batteries

Tel Aviv University researchers have found a novel way to control the atoms and molecules of peptides so that they "grow" to resemble small forests of grass. These "peptide forests" repel dust and water — a perfect self-cleaning coating for windows or solar panels which, when dirty, become far less efficient.

Hitting the Theoretical Roof of Converting Waste Heat to Electricity

The need to get rid of excess heat creates a major source of inefficiency in everything from computer processor chips to car engines. According to Peter Hagelstein, an associate professor of Electrical Engineering at MIT, existing solid-state devices to convert heat into electricity are not very efficient. Experimenting with thermal diodes, an MIT team has come closer to the theoretical limitations for the efficiency of such a conversion.
