The most wear-resistant metal alloy in the world

17-Aug-2018

If you're ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid -- not drive, skid -- around the Earth's equator 500 times before wearing out the tread. Sandia's materials science team has ...

Catalysts combination opens doors to making useful compounds

17-Aug-2018

Researchers have developed a new method that aids in the process of making valuable compounds by using a unique combination of catalysts. Huimin Zhao, Professor of Chemical and Biomolecular Engineering and leader of the Biosystems Design research theme at the Carl R. Woese Institute for Genomic ...

Particles pull last drops of oil from well water

Nanoscale solution to ‘produced water’ problem

17-Aug-2018

Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...

'Building up' stretchable electronics to be as multipurpose as your smartphone

16-Aug-2018

By stacking and connecting layers of stretchable circuits on top of one another, engineers have developed an approach to build soft, pliable "3D stretchable electronics" that can pack a lot of functions while staying thin and small in size. As a proof of concept, a team led by the University of ...

The behavior of water

New properties of H2O

15-Aug-2018

A team of scientists has uncovered new molecular properties of water--a discovery of a phenomenon that had previously gone unnoticed. Liquid water is known to be an excellent transporter of its own autoionization products; that is, the charged species obtained when a water molecule (H2O) is split ...

Microscopy Today Innovation Award for novel X-ray lenses

High numerical aperture and sharp focus enable record resolution microscopy

14-Aug-2018

For a novel X-ray lens with unprecedented properties, a research team headed by DESY group leader Saša Bajt has been awarded the 'Microscopy Today Innovation Award' by the magazine Microscopy Today. The team's “High numerical aperture, high efficiency X-ray lenses” were judged as one of the ten ...

Squeezing nanocrystals in a liquid droplet into a solid-like state and back again

13-Aug-2018

A team led by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) found a way to make a liquid-like state behave more like a solid, and then to reverse the process. They put a droplet of a liquid containing iron oxide nanocrystals into an oily liquid ...

The 2-D form of tungsten ditelluride is full of surprises

10-Aug-2018

The general public might think of the 21st century as an era of revolutionary technological platforms, such as smartphones or social media. But for many scientists, this century is the era of another type of platform: two-dimensional materials, and their unexpected secrets. These 2-D materials ...

Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way

10-Aug-2018

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that have a "super" ability to conduct electricity when chilled by liquid nitrogen? A team of scientists set out to answer this question in one ...
