Carbon nanotubes with big possibilities

A scientist at the U.S. Department of Energy’s Brookhaven National Laboratory, working with colleagues at the IBM T.J. Watson Research Center, has caused an individual carbon nanotube to emit light for the first time. This step in research on carbon nanotubes may help to materialize many of the proposed applications for carbon nanotubes, such as in electronics and photonics development.

The light emission is the result of a process called “electron-hole recombination.” By running an el

Another Twist in the Field of Superconductivity

Researchers at the U.S. Department of Energy’s Brookhaven National Laboratory have discovered an interesting type of electronic behavior in a recently discovered class of superconductors known as cobalt oxides, or cobaltates. These materials operate quite differently from other oxide superconductors, namely the copper oxides (or cuprates), which are commonly referred to as high-temperature superconductors.

When traditional superconductors are cooled to nearly absolute zero (0 Kelvin or –452

Europe at the forefront in research on solar, wave and geothermal energies

Today at the “Solar platform” test site in Almeria (Spain) the European Commission presented the state of play on its research programmes in alternative energy sources, including solar thermal, wave and geothermal energy. World energy consumption will double over the next 50 years, with Europe currently depending heavily on foreign energy sources. Currently, 41% of EU energy consumption is based on oil, followed by gas (23%), coal (15%), nuclear (15%) and only 6% is based on renewable energies. The t

Reactor of the future destroys nuclear waste – KTH to head major EU project to cut storage times dramatically

A power plant that generates energy from used nuclear waste and destroys it as well. Could this become a reality? A three-year research project involving 23 European partners coordinated by KTH is being launched to investigate the matter.

In the last few years great strides have been taken in research into so-called transmutation (see footnote) of nuclear waste. Therefore, the EU is now committing €4 million in Project Red Impact. The objective of the project is to present several alternati

Production nanophotonics – dream or reality?

Nanophotonics could well revolutionise the fields of telecommunications, computing and sensing, according to Professor Clivia Sotomayor Torres. But why is research into nanophotonics important?

It has the potential to provide ultra-small optoelectronic components, high speed and greater bandwidth. Professor Sotomayor Torres believes current research into fabricating nano-electronics could open the way for new methods of making nanophotonic devices, i.e. mass producing light handling devices

Surrey successfully demonstrate steam micro-propulsion in-orbit

Surrey Satellite Technology Ltd (SSTL) have demonstrated in-orbit the use of a steam propulsion system onboard the UK-DMC satellite, launched on 27th September 2003.

The novel micro-propulsion experiment used 2.06 grams of water as propellant. This ‘green’ propellant is non-toxic, non-hazardous to ground operators and results in improved specific impulse over conventional cold gas nitrogen, at a significantly lower cost.

During the first in-orbit firing, the thruster was pre-heated
