New bacteria-resistant materials discovered

August 13, 2012 3:53 am | News | Comments

Using state-of-the-art technology, scientists at The University of Nottingham have discovered a new class of polymers that are resistant to bacterial attachment. These new materials could lead to a significant reduction in hospital infections and medical device failures.

Graphene's behavior depends on where it sits

August 13, 2012 3:41 am | by David L. Chandler, MIT News Office | News | Comments

When you look at a gift-wrapped present, the basic properties of the wrapping paper are not generally changed by the nature of the gift inside. But surprising new experiments conducted at the Massachusetts Institute of Technology show that graphene behaves quite differently depending on the nature of material it's wrapped around. When sheets of graphene are placed on substrates made of different materials, fundamental properties can be drastically different, depending on the nature of the underlying material.

Discovery a big step toward room-temperature multiferroics

August 10, 2012 4:24 am | News | Comments

Multiferroics are expected to be applied to a new type of memory devices in which dielectric polarization is controlled by a magnetic field and magnetization is controlled by an electric field. However, multiferroic materials that function at room temperature are rare. In a breakthrough toward this goal, a  team in Japan and the U.K. have achieved ferroelectric polarization without a magnetic field after discovering that they could swap out atoms and still maintain control of the multiferroic’s dielectric and magnetic properties.

Study: Skin-aging radicals also age naturally-formed particles

August 10, 2012 3:54 am | by Jocelyn Duffy | News | Comments

Pine trees give off gases that react with airborne chemicals, creating tiny, invisible particles that muddy the air. New research shows that the biogenic particles formed from pine tree emissions are more chemically dynamic than previously thought. A study has generated the first experimental evidence that such compounds are chemically transformed by free radicals, the same compounds that age our skin, after they are first formed in the atmosphere.

Gecko feet hold clues to creating bandages that stick when wet

August 10, 2012 3:45 am | News | Comments

Scientists already know that the tiny hairs on geckos' toe pads enable them to cling, like Velcro, to vertical surfaces. Now, University of Akron researchers are unfolding clues to the reptiles' gripping power in wet conditions in order to create a synthetic adhesive that sticks when moist or on wet surfaces.

Cheaper, cleaner, more efficient catalyst for burning methane

August 9, 2012 12:06 pm | News | Comments

Researchers from the University of Pennsylvania, along with collaborators from Italy and Spain, have created a material that catalyzes the burning of methane 30 times better than currently available catalysts. The discovery offers a way to more completely exploit energy from methane, potentially reducing emissions of this greenhouse gas from vehicles that run on natural gas.

Stable charge-separated silver represents new materials class

August 9, 2012 9:16 am | News | Comments

Researchers at Argonne National Laboratory and in Switzerland have recently demonstrated the existence of long-lived charge-separated states in silver clusters. The stable charge-separated state, together with the fact that the clusters absorb light over a wide range of wavelengths, mean that the clusters represent a new and promising class of materials for solar energy applications.

New ballistic standard helps tie guns to criminals

August 9, 2012 5:30 am | News | Comments

Cartridge cases—the empty shells left behind after a gun is fired—are routinely sent to forensic laboratories for analysis when they're found at a shooting scene. Forensics experts need to have confidence in the accuracy of the equipment and procedures used to make a link, which makes the new standard reference material from NIST a valuable tool for law enforcement.

Advance in X-ray imaging shines light on nanomaterials

August 8, 2012 3:52 am | News | Comments

Up until now, most nanomaterial imaging has been done using electron microscopy. X-rays penetrate further into the material than electrons, but making lenses that focus X-rays is difficult and measuring the diffraction pattern of the sample has resulted in poor image quality. Researchers in the U.K., however, have invented a method to solve the image quality problem, revealing the 3D shape of gold nanocrystals in dramatic fashion.

New phenomenon in nanodisk magnetic vortices

August 8, 2012 3:48 am | News | Comments

New findings from a team of Lawrence Berkeley National Laboratory and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.
