New gas sensors patterned with conducting polymer

An improved method for depositing nanoporous, conducting polymer films on miniaturized device features has been demonstrated by researchers at the National Institute of Standards and Technology (NIST).

Described in the April 6 issue of the Journal of the American Chemical Society,* the method may be useful as a general technique for reproducibly fabricating microdevices such as sensors for detecting toxic chemicals.

Unlike most polymers, conducting polymers have the elec

New Material Structure Produces World’s Fastest Transistor

A new type of transistor structure, invented by scientists at the University of Illinois at Urbana-Champaign, has broken the 600 gigahertz speed barrier. The goal of a terahertz transistor for high-speed computing and communications applications could now be within reach. The new device – built from indium phosphide and indium gallium arsenide – is designed with a compositionally graded collector, base and emitter to reduce transit time and improve current density. With their pseud

New sensors that see rubbish and gas

The SINTEF Group, in co-operation with the re-cycling company Tomra now goes beyond cash deposits for bottles and cans to recycling plastic, glass and metal. Newly developed, patented technology makes it possible to sort different types of plastic, different colours of glass as well as metal – easily, effectively and inexpensively. A new, inexpensive gas-detector that contributes to a better indoor climate, is another area of use.

Although many things can be recycled or reused,

Terrorist-proof buildings from new high-tech sensors

Scientists develop a breed of sensors that can survive extremes of heat and pressure

Scientists have developed a new breed of sensors which can survive incredible levels of pressure and heat and that are helping researchers work out how to make buildings that could survive massive explosions. Professor Julian Jones, of Heriot-Watt University, will reveal the next generation of sensing devices at the Institute of Physics conference Physics 2005 in Warwick, heralding a new range of me

Fresh air for air passengers

Air travellers rarely think about the indoor climate in airport terminals, or about the kitchens where their in-flight meals are prepared. These catering centres are vast, busy facilities, often located in hot, humid climates – posing a challenge to ventilation systems. Air distribution in public areas of airports is another crucial, demanding speciality.

Finnish technology offers indoor climate solutions for two dozen airports as far-flung as Shanghai, New York, Auckland and Brussels. Pic

Vulcain 2 engine now in full production

A small ceremony took place yesterday at the site of Snecma Moteurs in Vernon, France, to mark the beginning of industrial production of the Vulcain 2 engine, designed for the new Ariane 5 ECA and Ariane 5 ES ATV launchers.

Present at the ceremony was Patrick Devedjian, the French Minister for Industry and Jean-Paul Béchat, Chairman of the Executive Board of Sagem-Snecma. ESA was represented by Antonio Fabrizi, Director of Launchers and Robert Lainé, Head of the Ariane Department.
