Tungsten suboxide improves the efficiency of platinum in hydrogen production

30-Oct-2019

Researchers presented a new strategy for enhancing catalytic activity using tungsten suboxide as a single-atom catalyst (SAC). This strategy, which significantly improves hydrogen evolution reaction (HER) in metal platinum (pt) by 16.3 times, sheds light on the development of new electrochemical ...

Disordered materials could be hardest, most heat-tolerant carbides

Simulations predict new class of carbides

28-Nov-2018

Materials scientists at Duke University and UC San Diego have discovered a new class of carbides expected to be among the hardest materials with the highest melting points in existence. Made from inexpensive metals, the new materials may soon find use in a wide range of industries from machinery ...

New solar tech can take the heat and pressure

New material, manufacturing process use sun's heat for cheaper renewable electricity

22-Oct-2018

Solar power accounts for less than 2 percent of U.S. electricity but could make up more than that if the cost of electricity generation and energy storage for use on cloudy days and at nighttime were cheaper. A Purdue University-led team developed a new material and manufacturing process that ...

Nearly pure nanotubes from unusual catalyst

30-Jul-2018

Growing a batch of carbon nanotubes that are all the same may not be as simple as researchers had hoped, according to Rice University scientists. Rice materials theorist Boris Yakobson and his team bucked a theory that when growing nanotubes in a furnace, a catalyst with a specific atomic ...

Unexpected effect could lead to lower-power memory, computing devices

20-Mar-2018

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron magnet (CoFeB) sandwiched at the ends by gold (Au) electrodes on ...

Nanocrystalline diamonds used to study materials under extreme conditions

07-Feb-2018

Using a nanocrystalline diamond built by plasma vapor deposition, Yogesh Vohra, Ph.D., has already produced a pressure nearly two times greater than that found at the center of the Earth. Now he reports that the manufacturing process of these novel, nanocrystalline-diamond micro-anvils has proved ...

Tungsten offers nano-interconnects a path of least resistance

06-Oct-2017

As microchips become ever smaller and therefore faster, the shrinking size of their copper interconnects leads to increased electrical resistivity at the nanoscale. Finding a solution to this impending technical bottleneck is a major problem for the semiconductor industry. One promising ...
