Device only atoms across may allow infinitesimal but powerful computers

Single-molecule diode may change Moore’s ’law’ of microchip memory

Using the power of modern computing combined with innovative theoretical tools, an international team of researchers has determined how a one-way electrical valve, or diode, made of only a single molecule does its job.

Diodes are critical components within computer, audio equipment and countless other electronic devices. If designers can swap existing diodes with the single-molecule one,

Solar cell manufacturing process examined with a view to increasing cell efficiency

Electro-optical characterization of in-situ indium doped CdS thin films by chemical bath

As the world becomes increasingly aware of global warming and climate change, the need for alternative energy sources is generating greater demand. Electricity generated from solar cells is often quoted as being the solution to our climate problems. Unfortunately, this method of energy generation is quite inefficient. Overcoming this inefficiency is key to the widespread commercial acceptan

Cool nanotechnology can save energy

Huge reductions in heating bills, safer surgery and the next generation of miniaturised computers are among the potential benefits of new nanotechnology developed at Leeds.

By suspending nanoparticles in water or other liquids, Professor Richard Williams and Dr Yulong Ding have created ‘nanofluids’ which can transfer heat up to 400% faster than other liquids. In a central heating system, nanofluids could increase efficiency without the need to use a more powerful pump, so saving energy and

Coal-based jet fuel poised for next step

A jet fuel comparable to Jet A or military JP 8, but derived from at least 50 percent bituminous coal, has successfully powered a helicopter jet engine, according to a Penn State fuel scientist.

“Because the fuel is 50 percent derived from coal, it could reduce our use of imported petroleum for this purpose by half,” says Dr. Harold H. Schobert, professor of fuel science and director of Penn State’s Energy Institute. “We have shown in tests that the mix can go to at least 75

New sensor technology detects chemical, biological, nuclear and explosive materials

Applications for homeland security, emergency planning

Engineers at the U.S. Department of Energy’s Argonne National Laboratory, using an emerging sensing technology, have developed a suite of sensors for national security applications that can quickly and effectively detect chemical, biological, nuclear and explosive materials.

“We can use this technology to detect chemical and biological agents and also to determine if a country is using its nuclear reactors to pro

Energy prices, uncertainty and energy saving by companies

Why do so many companies fail to make use of the energy-saving technologies which are available? Dutch researcher Mark Koetse used a meta-analysis of various empirical studies to assess the relevance of two possible explanations.

Meta-analysis is a research method that has been gradually gaining ground within economics since the mid-1980s. The doctoral research of Mark Koetse focused on the problems associated with this methodology. That is why in his thesis he described the ne
