Twisting the light away

Add a deceptively simple twist to a tiny fiber of glass and you get a versatile new class of optical devices to filter light; sense changes in temperature, pressure or other environmental factors; or transmit information via powerful, inexpensive lasers, according to researchers at Chiral Photonics Inc. of Clifton, N.J. Writing in the July 2 issue of Science, the company describes a new class of devices called chiral gratings that were developed with support from the Advanced Technology Program at t

USC scientist invents technique to grow superconducting and magnetic ’nanocables’

’we can supply a group of previously unavailable materials to the nanotechnology community’

A University of Southern California engineer has discovered a way to manufacture composite “nanocables” from a potent new class of substances with extraordinary properties called Transition Metal Oxides (TMOs).

Chongwu Zhou, an assistant professor in the USC Viterbi School of Engineering’s Department of Electrical Engineering, is creating dense arrays of ultrafine wires made of magn

Horns Reef work in progress

As previously informed, Vestas has experienced a series of problems with the operation of the offshore project Horns Reef located in the North Sea, 15 kilometres off the shore near Esbjerg located on the Danish west coast.

Harsh environment

The environment at Horns Reef is harsh and it has been ascertained that all transformers and a number of generators had to be changed. In close and constructive collaboration with the customer, the Danish utility Elsam, Vestas and ABB a

A New Twist On Fiber Optics

Spiraling glass fibers provide new way to control behavior of light By twisting fiber optic strands into helical shapes, researchers have created unique structures that can precisely filter, polarize or scatter light. Compatible with standard fiber optic lines, these hair-like structures may replace bulky components in sensors, gyroscopes and other devices. While researchers are still probing the unusual properties of the new fibers, tests show the strands impart a chiral, or

Making the future with nanoelectronics: a strategy for Europe

To become the world’s most competitive powerhouse, Europe must lead the transition of the micro-electronics sector to the next generation of nano-electronics, with co-ordinated public and private investments of at least €6 billion per year. This is the message from a report drawn up by CEOs of leading companies and research organisations and presented today to European Research Commissioner Philippe Busquin and Enterprise and Information Society Commissioner Erkki Liikanen. Smarter and smaller elec

Purdue Yeast Makes Ethanol from Agricultural Waste More Effectively

A strain of yeast developed at Purdue University more effectively makes ethanol from agricultural residues that would otherwise be discarded or used as animal feed, and the first license for the yeast has been issued to the biotechnology company Iogen Corp.

Purdue’s genetically altered yeast allows about 40 percent more ethanol to be made from sugars derived from agricultural residues, such as corn stalks and wheat straw, compared with “wild-type” yeasts that occur in nature.
