Researchers at the University of Rochester have demonstrated that using powerful femto-second laser pulses to etch metal surfaces with nanoscale structures could help create highly efficient solar power generators. The researchers found that tungsten, which is commonly used as a thermal solar absorber, has the highest solar absorption efficiency when treated with the new nanoscale structures.

New research by engineers at MIT, the University of Central Florida, the University of Texas at Austin, Brookhaven National Laboratory, and Hong Kong Polytechnic University could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery's two electrodes, the anode. To form the anode, the researchers developed a three-dimensional nanoarchitecture in the form of a honeycomb-like array of hexagonal tubes, partially infused with solid lithium metal. The hexagonal tubes are about 100 to 300 nanometers in diameter and tens of microns in height.

This article is an interview with Ashwin Shahani, an assistant professor of materials science and engineering at the University of Michigan, whose research has revealed that an intricate and beautiful set of nanoscale rods, sheets, and spirals forms spontaneously in cooling metal alloys. His research could lead to a new generation of lightweight alloys and optical products with properties superior to monolithic materials.

Scientists at the U.S. Naval Research Laboratory have discovered a new platform for quantum technologies by suspending two-dimensional crystals over pores in a slab of gold. This new approach may help develop new materials for secure communication and sensing technologies based on the unique laws of physics at the atomic level.

Researchers have, for the first time, created and imaged a novel pair of quantum dots – tiny islands (100 nanometers in diameter) of confined electric charge that act like artificial atoms. Such a ''coupled'' quantum dot could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer.
