Using photon emissions from individual molecules of silver, researchers at the Georgia Institute of Technology have created what may be the world’s smallest electroluminescent light source.

Believed to be the first demonstration of electroluminescence from individual molecules, the work could lead to new types of nanometer-scale optical interconnects, high-resolution optical microscopy, nanometer-scale lithography and other applications that require very small light sources. And becaus

An enormous source of clean energy is available to us. We see it almost every day. It’s just a matter of harnessing it.

The problem with solar energy is that it has not been inexpensive enough in the past. David Kelley, professor of chemistry at Kansas State University, developed a new type of nanoparticle — a tiny chemical compound far too small to be seen with the naked eye — that may reap big dividends in solar power.

Kelley’s team is studying the properties and tech

New technology for generating power from coal mining waste was launched by the Federal Minister for Industry, Tourism and Resources, the Hon. Ian Macfarlane, at CSIRO in Brisbane today.

The revolutionary technology has the potential to significantly reduce greenhouse gases and bring big savings to mining companies operating coal mines.

The CSIRO-Liquatech hybrid coal and gas turbine system unveiled at the Queensland Centre for Advanced Technologies will generate electricity from wa

The kerosene that lights your heater or stove might be the same type of fuel powering the nation’s next space vehicle.

Kerosene — almost as common to American life as gasoline — is being considered as a fuel for two main engine candidates for a second generation reusable launch vehicle, now in development by the Space Launch Initiative. The Initiative is NASA’s technology development program to design a complete space transportation system with increased safety and reliability at a lower c

Siemens Automation and Drives (A&D) presents new electronic components in the Delta switches and socket outlets range for the retrofit market in the area of lighting and shutters. The new products include universal dimmer and shutter control inserts, conventional and wireless operator pushbuttons, and a battery-operated wall-mounted transmitter.

The “sys universal dimmer insert” is suitable for all types of lighting to 420 watts/volt-ampere connected load. The dimmer can be easily retrofitt

Photovoltaics is a science that examines light-electricity conversion. Conversion of solar energy carried by photons is transformed by solar cells into direct-current electrical energy. Interest in the use of photovoltaic (PV) solar technologies is growing rapidly, as it will permit the direct production of electricity from solar radiation without any harmful emissions or noise. Rising energy costs, the finite nature of fossil fuels and worries about climate change has renewed interest in making the
