Origami inspires research into materials that self-assemble when exposed to light

August 23, 2012 10:20 am | News | Comments

A multi-university research team led by North Carolina State University will be developing methods to create 2D materials capable of folding themselves into 3D objects when exposed to light. The effort, which is funded by a grant from the National Science Foundation, is inspired by origami and has a broad range of potential applications.

Biocompatible cellulose nanostructures could speed wound recovery

August 23, 2012 6:30 am | News | Comments

Nanocellulose is a highly fibrillated material, composed of nanofibrils with diameters in the nanometer scale, with high aspect ratio and high specific surface area. Recently, the suitability of cellulose nanofibrils from wood for forming elastic cryogels has been demonstrated by scientists. These gels could improve wound healing if used in dressings.

Mars rover passes driving test, looks to hit road

August 23, 2012 4:14 am | by Alicia Chang, AP Science Writer | News | Comments

Curiosity’s test drive was a success, allowing scientists at NASA to begin planning their next move. An intriguing spot 1,300 feet will mark the rover’s first attempt to drill into bedrock. The ultimate destination is Mount Sharp, a towering mountain that looms from the ancient crater floor. Signs of past water have been spotted at the base, providing a starting point to hunt for the chemical building blocks of life.

New crystalline material could bring down of cost of electronics, computers

August 23, 2012 4:06 am | by Megan Fellman | News | Comments

A team of organic chemists have discovered they can create very long crystals with desirable properties using just two small organic molecules that are extremely attracted to each other. The attraction between the two molecules causes them to self assemble into an ordered network, and, most importantly, they possess the ferroelectric properties that are useful in computing.

Superconductor 'flaws' could be key to its abilities

August 23, 2012 4:04 am | News | Comments

Physicists who study superconductivity strive to create a clean, perfect sample. But a Purdue University team that has mapped seemingly random, four-atom-wide dark lines of electrons on the surface of copper-oxygen based superconducting crystals has discovered that they exist throughout the crystal. The findings suggest the lines, which are “flaws”, could play a role in the material's superconductivity at much higher temperatures than others.

One-molecule-thick material has big advantages

August 23, 2012 3:44 am | by David L. Chandler, MIT News Office | News | Comments

Graphene has been heralded for its strength and other novel characteristics, but one property in particular—its 2D nature—suggests that graphene its just the start of a wave of new 2D materials. The latest one, molybdenum disulfide, was first described just a year ago by researchers in Switzerland. In that year, researchers at Massachusetts Institute of Technology, which struggled unsuccessfully to build circuits from graphene, succeeded in making a variety of electronic components from molybdenum disulfide. They say the material could help usher in radically new products.
