New nanostructure technology provides advances in eyeglass, solar energy performance

17.09.2009
Chemical engineers at Oregon State University have invented a new technology to deposit "nanostructure films" on various surfaces, which may first find use as coatings for eyeglasses that cost less and work better.

Ultimately, the technique may provide a way to make solar cells more efficiently produce energy.

The films reduce the reflectance of light, and in the case of eyeglasses would capture more light, reduce glare and also reduce exposure to ultraviolet light. Some coatings with these features are already available, but the new technology should perform better at a lower cost, and be able to be applied on-site in a dispenser's office.

"There's really a whole range of things this technology may ultimately be useful for," said Chih-hung Chang, an associate professor in the OSU Department of Chemical, Biological and Environmental Engineering. "They should be able to make almost any type of solar energy system work more efficiently, and ultimately could be used in cameras or other types of lenses."

A patent has been applied for on the new technology, and the first commercial products may be ready within a year, Chang said.

The key to the process is use of a chemical bath, controlled by a microreactor, to place thin-film deposits on various substrates such as glass, plastic, silicon or aluminum. In this case, the technology will create a type of nanostructure that resembles millions of tiny pyramids in a small space, which function to reduce the reflectance of any light that strikes the material.

The scientists are now working on the application of this thin film to polycarbonate, the type of plastic most commonly used in eyeglass production, and also plan to create a small unit that can apply the films inexpensively in an office setting.

The final product should be faster to apply, less costly, reduce waste of materials and perform better than existing technologies, the researchers said.

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
