A nanoscale glimpse of batteries in action

Lithium–oxygen (Li–O2) batteries are a new type of experimental battery that electric car manufacturers are hoping will address the issue of limited driving range. Unlike the lithium-ion batteries used today, lithium–oxygen ...

Engineers solve energy puzzle

University of Toronto materials science and engineering (MSE) researchers have demonstrated for the first time the key mechanism behind how energy levels align in a critical group of advanced materials. This discovery is ...

Living on the edge: How a 2-D material got its shape

Ever since its discovery in 2004, graphene—an atomically thin material with amazing strength and electrical properties—has inspired scientists around the world to design new 2-D materials to serve a broad range of applications, ...

World record silicon-based millimeter-wave power amplifiers

Two teams of DARPA performers have achieved world record power output levels using silicon-based technologies for millimeter-wave power amplifiers. RF power amplifiers are used in communications and sensor systems to boost ...

Copper nanowires could become basis for new solar cells

(Phys.org) —By looking at a piece of material in cross section, Washington University in St. Louis engineer Parag Banerjee, PhD, and his team discovered how copper sprouts grass-like nanowires that could one day be made ...

First detailed electronic study of new nickelate superconductor

The discovery last year of the first nickel oxide material that shows clear signs of superconductivity set off a race by scientists around the world to find out more. The crystal structure of the material is similar to copper ...
