How iron feels the heat

New findings could one day help researchers design better and stronger steel

17-Feb-2015

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 from teapots to skyscrapers. But the details of just how and why ...

New self-stretching material developed

No limit to number of times material can change shape

17-Feb-2015

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation. The findings were recently published in the journal ACS Macro ...

Better catalysts, made-to-order

Scientists have taken a big step toward the rational design of catalysts

16-Feb-2015

Most of our food, medicine, fuel, plastics and synthetic fibers wouldn't exist without catalysts, materials that open favorable pathways for chemical reactions to run forth. And yet chemists don't fully understand how most catalysts work, and developing new catalysts often still depends on ...

Scientists get first glimpse of a chemical bond being born

A fundamental advance has big implications for making chemistry more efficient

16-Feb-2015

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. This fundamental advance, reported Feb. 12 in Science Express and ...

Better batteries inspired by lowly snail shells

13-Feb-2015

Scientists are using biology to improve the properties of lithium ion batteries. Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, which binds strongly to lithium manganese nickel oxide (LMNO), a material that can be used to ...

Buckyballs offer environmental benefits

In Rice University study, treated carbon-60 molecules remove metals from liquids

12-Feb-2015

Treated buckyballs not only remove valuable but potentially toxic metal particles from water and other liquids, but also reserve them for future use, according to scientists at Rice University.The Rice lab of chemist Andrew Barron has discovered that carbon-60 fullerenes (aka buckyballs) that ...

New design tool for metamaterials

Berkeley Lab study shows how to predict metamaterial nonlinear optical properties

11-Feb-2015

Metamaterials - artificial nanostructures engineered with electromagnetic properties not found in nature - offer tantalizing future prospects such as high resolution optical microscopes and superfast optical computers. To realize the vast potential of metamaterials, however, scientists will need ...
