A chemistry professor has come up with a more sustainable way to make silicon at much lower temperatures for the kind of advanced batteries used in electronics such as phones, cameras and laptop computers.
The miniature solar panels could power myriad personal devices — wearable medical sensors, smartwatches, even autofocusing contact lenses.
"If you ask an ordinary person, ‘What is glass?’ they will point to a window, but glass is a much broader category of materials,” says Mark Ediger.
Tiny sheets of the semiconductor zinc oxide could have huge implications for the future of a host of electronic and biomedical devices.
University of Wisconsin–Madison engineers have developed a new approach to structuring the catalysts used in essential reactions in the chemical and energy fields. The advance offers a pathway for industries to wean themselves off of platinum, one of the scarcest metals in the earth's crust.
