How iron feels the heat

As you heat up a piece of iron, the arrangement of the iron atoms changes several times before melting. This unusual behavior is one reason why steel, in which iron plays a starring role, is so sturdy and ubiquitous in everything ...

Less expensive fuel cell may be possible

Scientists at Los Alamos National Laboratory have developed a new class of hydrogen fuel-cell catalysts that exhibit promising activity and stability. The catalysts are made of low-cost nonprecious metals entrapped in something ...

Discovery could lead to jet engines that run hotter—and cleaner

Researchers here have made a discovery in materials science that sounds like something from the old Saturday morning cartoon Super Friends: They've found a way to deactivate "nano twins" to improve the high-temperature properties ...

Scientists watch diamond turn into graphite

In a surprising achievement, a team of scientists has turned diamond into graphite, using an X-ray laser. What may seem undesirable at first glance, is a decisive step forward in understanding the fundamental behaviour of ...

PhD student solves decade-long mystery of magnetism

(PhysOrg.com) -- A PhD student from the London Centre for Nanotechnology has won a prize for solving a decade-long mystery central to understanding modern magnetic systems.

Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their ...

One of the most important problems in materials science solved

Together with three colleagues Professor Peter Oppeneer of Uppsala University has explained the hitherto unsolved mystery in materials science known as 'the hidden order' - how a new phase arises and why. This discovery ...

Scientists get first glimpse of a chemical bond being born

Scientists have used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to get the first glimpse of the transition state where two atoms begin to form a weak bond on the way to becoming a molecule.
