Ions, not particles, make silver toxic to bacteria

July 11, 2012 8:26 am | News | Comments

Rice University researchers have recently settled a long-standing controversy over the mechanism by which silver nanoparticles, the most widely used nanomaterial in the world, kill bacteria. Scientists have long suspected silver nanoparticles themselves may be toxic to bacteria, but not so. Ionization is the key.

Triboelectric generator captures power from plastic

July 9, 2012 11:58 am | News | Comments

Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us—this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this "triboelectric" generator could provide alternating current from activities such as walking.

Tiny bubbles snap carbon nanotubes like twigs

July 9, 2012 7:46 am | News | Comments

A computer model from Rice University shows that long nanotubes bend and snap like a twig when blasted with ultrasonic energy. The research finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.

Sounding rocket mission has finest mirrors ever made

July 9, 2012 6:28 am | News | Comments

On July 11, NASA scientists will launch into space the highest resolution solar telescope ever to observe the solar corona. Often one improves telescope resolution simply by building bigger mirrors, but this is not possible when constraining a telescope to the size of a sounding rocket, so the High Resolution Coronal Imager (Hi-C) orbiter has a 9.5-inch with a variance of less than two atoms.

Subatomic details of exotic ferroelectric nanomaterials

July 9, 2012 4:42 am | News | Comments

As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact and efficient devices. In new research, scientists at Brookhaven and Lawrence Berkeley national laboratories and other collaborating institutions describe one such advance—a technique, called electron holography, revealing unprecedented details about the atomic structure and behavior of exotic ferroelectric materials. The research could guide the scaling up of these materials.

Catalysts open green route to chemical products

July 9, 2012 4:16 am | by Kimm Fesenmaier, California Institute of Technology | News | Comments

California Institute of Technology chemists have developed a new class of catalysts that will increase the range of chemicals that can be synthesized using environmentally friendly methods. The new chemicals include the metal ruthenium and help drive a chemical reaction called olefin metathesis. The reaction has proven useful and efficient for making chemical products that involve pairs of carbon atoms connected by double bonds.

Molecule changes magnetism and conductance

July 5, 2012 7:35 am | News | Comments

One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers in Germany and Japan have now developed a magnetic memory with one bit per molecule. Using an electric pulse deliver by atomic force microscopy, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state.
