Solving molybdenum disulfide's 'thin' problem

Research team increases material's light emission by twelve times

01-Apr-2015

The promising new material molybdenum disulfide (MoS2) has an inherent issue that's steeped in irony. The material's greatest asset - its monolayer thickness - is also its biggest challenge.Monolayer MoS2's ultra-thin structure is strong, lightweight, and flexible, making it a good candidate for ...

Researchers synthesize material for efficient plasmonic devices in mid-infrared range

18-Feb-2015

A research team led by North Carolina State University has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared (IR) range. This is the first time anyone has demonstrated a material that performs efficiently in ...

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 ...

Freshmen-level chemistry solves the solubility mystery of graphene oxide films

Common contaminant found responsible for the material's stability in water

07-Jan-2015

A Northwestern University-led team recently found the answer to a mysterious question that has puzzled the materials science community for years - and it came in the form of some surprisingly basic chemistry.Like many scientists, Jiaxing Huang did not understand why graphene oxide (GO) films were ...

Penn researchers show commonalities in how different glassy materials fail

11-Dec-2014

Glass is mysterious. It is a broad class of materials that extends well beyond the everyday window pane, but one thing that these disparate glasses seem to have in common is that they have nothing in common when it comes to their internal structures, especially in contrast with highly ordered and ...
