Nanotechnology changes behavior of materials

One of the reasons solar cells are not used more widely is cost—the materials used to make them most efficient are expensive. Engineers are exploring ways to print solar cells from inks, but the devices don't work as well.

A coating that protects against heat and oxidation

Researchers have developed a coating technique that they plan to use to protect tur- bine engine and waste incinerator components against heat and oxidation. A topcoat from micro-scaled hollow aluminium oxide spheres provides ...

High performance ceramics for cars

An ambitious project is taking shape at Empa's Laboratory for High Performance Ceramics: ceramic brake disks for compact cars. Empa scientists have teamed up with partners from Italy, Spain and Liechtenstein to develop the ...

Making quantum dots glow brighter

Researchers from the University of Alabama in Huntsville and the University of Oklahoma have found a new way to control the properties of quantum dots, those tiny chunks of semiconductor material that glow different colors ...

Copper nanowires could become basis for new solar cells

(Phys.org) —By looking at a piece of material in cross section, Washington University in St. Louis engineer Parag Banerjee, PhD, and his team discovered how copper sprouts grass-like nanowires that could one day be made ...
