Cathode 'defects' improve battery performance

Engineers strive to design smartphones with longer-lasting batteries, electric vehicles that can drive for hundreds of miles on a single charge, and a reliable power grid that can store renewable energy for future use. Each ...

New electrode design may lead to more powerful batteries

New research by engineers at MIT and elsewhere 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, ...

First view of hydrogen at the metal-to-metal hydride interface

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the ...

Researchers' golden touch enhances quantum technology

Scientists at the U.S. Naval Research Laboratory discovered a new platform for quantum technologies by suspending two-dimensional (2-D) crystals over pores in a slab of gold. This new approach may help develop new materials ...

Making new catalysts from unique metallic alloys

Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ability to regain their original ...

Measuring the wear and tear of metals

For the past 50 years, researchers at the National Institute for Materials Science (NIMS) have been conducting detailed short- and long-term testing of a wide variety of structural materials manufactured in Japan to ensure ...

Surface effects affect the distribution of hydrogen in metals

The researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) and Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences studied the distribution of hydrogen in metals in the ...
