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.

Bacteria Turns Carbon Dioxide Into Liquid Fuel

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which has great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.

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.
