New solar cell design uses ‘invisible’ nanowires to harness power potential of reflected light

By Stephanie Liverani / December 2, 2015

Scientists at Stanford University in California are developing a new solar cell that uses ‘invisible’ nanowires to redirect sunlight that is reflected away and lost with traditional solar cell designs.

Apple’s gold made stronger with ceramics

By Jessica McMathis / March 15, 2015

The gold in Apple’s watch is far from pure: The alloy is actually one-quarter ceramic reinforcement that makes the gold “twice as hard,” more scratch resistant, and less dense.

Several recent, unrelated posts have been about materials with nanoscale porosity (diamond aerogels, chalcogenide PCMM). Here is another one, but perhaps this one will prove to be not so unrelated. In the June 3 issue of Science, authors Jin and Weissmüller describe a…

Nanoscale intergranular films shed light on grain boundary behavior

By Eileen De Guire / May 26, 2011

During one of their studies, grain boundary researchers began with gold films broken into particles (via annealing) dispersed across a sapphire substrate. Credit: Baram, et al; Technion. Materials scientists have long recognized that grain boundaries and interfaces can limit a material’s bulk properties, especially at high temperatures. Significant research effort has gone into understanding their nature with an eye to…

Gold used to enhance nanocrystal conductance

By / September 15, 2009

Researchers at Berkeley Lab reported a technique by which the electrical conductivity of nanorod crystals of cadmium-selenide was increased 100,000 times. “The key to our success is the fabrication of gold electrical contacts on the ends of cadmium-selenide rods via direct solution phase-growth of the gold tips,” says Paul Alivisatos, interim-director of Berkeley Lab, who…

3-2-1, Liftoff!

By / July 16, 2009

After five failed attempts, space shuttle Endeavour lifted off at NASA’s Kennedy Space Center in Florida on the STS-127 mission to the International Space Station. Endeavour’s flight will deliver the final components of the Japan Aerospace Exploration Agency’s Kibo laboratory to the ISS. The 16-day mission will include five spacewalks and the installation of two…
