The technique, called cathodoluminescence tomography, could assist in the development of high-efficiency solar cells and LEDS, or improve the way biological systems are visualized.
To design the next generation of optical devices, ranging from efficient solar panels to LEDs to optical transistors, engineers will need a 3-dimensional image depicting how light interacts with these objects on the nanoscale.
Unfortunately, the physics of light has thrown up a roadblock in traditional imaging techniques: the smaller the object, the lower the image's resolution in 3-D.

Silicon isn't the only chip-making material under the sun, just the cheapest. But a new process could make the alternative material, gallium arsenide, more cost effective.
Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water.

Associate Professor Yi Cui and his students have turned a material commonly used in surgical gloves into a low-cost, highly efficient air filter. It could be used to improve facemasks and window screens, and maybe even scrub the exhaust from power plants.
In the past few years, Yi Cui has made several business trips to China. Each time he has found himself choked by smog produced by automobiles and coal power plants.
After a few of these trips, Cui, an associate professor of materials science and engineering at Stanford, came up with an idea to clean the pollution. He and his graduate students set to work designing an inexpensive, efficient air filter that could ease the breathing for people in polluted cities.

Putting a film of the crystalline material perovskite on top of a silicon solar cell increases the cell's efficiency nearly 50 percent, Stanford engineers say.
Stacking perovskites, a crystalline material, onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford engineers.
The researchers describe their novel perovskite-silicon solar cell in the journal Energy & Environmental Science.

Using high-brilliance X-rays in a new way, Stanford engineers observed electrons at work during catalytic reactions. Their findings challenge long-held theories about some catalysts, opening the door to new or improved renewable energy applications.
Many of today's most promising renewable energy technologies – fuel cells, water splitters and artificial photosynthesis – rely on catalysts to expedite the chemical reactions at the heart of their potential. Catalysts are materials that enhance chemical reactions without being consumed in the process. For more than a century, engineers across the world have engaged in a near-continual search for ways to improve catalysts for their devices and processes.
