Search for new semiconductors heats up with gallium oxide

ScienceDaily.com: Nanotechnology News - Mon, 07/22/2019 - 21:24
Electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field's hottest material -- beta-gallium oxide -- to their arsenal. Beta-gallium oxide is readily available and promises to convert power faster and more efficiently than today's leading semiconductor materials -- gallium nitride and silicon, the researchers said.

'Diamonds from the sky' chemistry converts greenhouse gas into valuable nanocarbon materials

NanoWerk.com - Fri, 07/19/2019 - 14:25
Carbon nano-onions (CNOs), a less studied morphology of carbon nanomaterials, are exotic structures with extraordinary properties and numerous applications. These applications have been largely ignored due to their high synthesis cost. Researchers now have produced inexpensive, stable carbon-nano onions directly from carbon dioxide. The carbon dioxide reactant replaces nano-diamonds as the reactant to form the nano-onions. The source of CO2 to produce these CNOs can be the consumption of industrial flue gas or CO2 directly captured from the air.
