Researchers develop new method of controlling nanodevices

In a discovery that could lead to big changes in storing digital information and powering motors in small hand-held devices, researchers at UCLA have developed a method for switching tiny magnetic fields on and off with an electric field - a sharp departure from the traditional approach of running a current through a wire.

Gold Nanorods a whole new way of harvesting solar energy

A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods.

Researchers demonstrate fullerene crystals with bimodal pore architectures

Scientists for the first time demonstrated template-free novel mesoporous carbon material: fullerene (C60) crystals with bimodal pore architectures and having highly crystallized framework. Experiments have proven that this novel meso- and macroporous material show better electrochemical performance compared to pristine C60 due to higher electrochemically active surface areas.

Protein 'passport' helps nanoparticles get past immune system

The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices like pacemakers or artificial joints, are just as foreign and subject to the same response. Now, rersearchers have figured out a way to provide a "passport" for such therapeutic devices, enabling them to get past the body's security system.

Titanium dioxide nanoreactor

Researchers have developed a synthesis to produce nanoparticles at room temperature in a polymer network. Their analysis has revealed the crystalline structure of the nanoparticles. This represents a major step forward in the usage of polymeric nanoreactors since, until recently, the nanoparticles had to be thoroughly heated to get them to crystallize.

Supramolecular velcro for underwater adhesion

When gluing things together, both surfaces usually need to be dry. Gluing wet surfaces or surfaces under water is a challenge. Korean scientists have now introduced a completely new concept. They were able to achieve reversible underwater adhesion by using supramolecular "velcro".
