Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature.

What is common to blood, ink and gruel? They are all liquids in which tiny particles are suspended – so called “colloids”

A new advance in solar cells that tips the surface with minuscule cone structures could neutralize manufacturing defects, boosting efficiency up to 80 percent. In conventional solar panels, more than 50 percent of the charges generated by sunlight are lost due to defects, said Jun Xu, a researcher at the Department of Energy's Oak Ridge National Laboratory. The irregularities in the formation of the crystalline structure of solar cells can trap electrons and limit the transfer of sunlight to electrical energy.
