Engineers discover a high-speed nano-avalanche

Charles McLaren, a doctoral student in materials science and engineering at Lehigh University, arrived last fall for his semester of research at the University of Marburg in Germany with his language skills significantly ...

NASA study finds solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according ...

Storing a Lightning Bolt in Glass for Portable Power

(PhysOrg.com) -- Materials researchers at Penn State University have reported the highest known breakdown strength for a bulk glass ever measured. Breakdown strength, along with dielectric constant, determines how much energy ...

Vacuum arcs spark new interest

Whenever two pieces of metal at different voltages are brought near each other, as when an appliance is plugged into a live socket, there is a chance there will be an arc between them. Most of the arcs people see are a breakdown ...

Gallium nitride transistor could replace silicon

(PhysOrg.com) -- A Cornell researcher has created an extremely efficient transistor made from gallium nitride, which may soon replace silicon as king of semiconductors for power applications.

Graphene Shows High Current Capacity and Thermal Conductivity

(PhysOrg.com) -- Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a ...

Promising new alloy for resistive switching memory

Memory based on electrically-induced "resistive switching" effects have generated a great deal of interest among engineers searching for faster and smaller devices because resistive switching would allow for a higher memory ...
