Heat power plants (HPPs) supply electrical energy to many cities in the world. The production of heat and electricity starts with burning coal in a combustion…
Researchers previously thought that acoustic tractor beams were fundamentally limited to levitating small objects as all the previous attempts to trap…
The Solar Cells Laboratory of the Calibration and Test Center (CalTeC) at the Institute for Solar Energy Research (ISFH) has been added to the list of…
Our daily life depends more than ever on a reliable electricity supply.
In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves a question: Why not simply use water as an electrolyte? Water…
Metalenses — flat surfaces that use nanostructures to focus light — promise to revolutionize optics by replacing the bulky, curved lenses currently used in optical devices with a simple, flat surface. But, these metalenses have remained limited in the spectrum of light they can focus well. Now a team of researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed the first single lens that can focus the entire visible spectrum of light —…
New research featured in Ecology Letters showcases how streams can be used as sensors to diagnose a watershed's sensitivity or resiliency to changes in land…
A team of researchers led by the Department of Energy's Oak Ridge National Laboratory used a high-resolution inelastic X-ray scattering technique to measure…
Ten times more powerful than its predecessor, the world's largest and most powerful plasma injector has begun operation at General Fusion's facilities in…
Monocrystalline silicon solar cell achieves 25.7% efficiency
“Flexible electronics hold promise for use in many fields, but there are significant manufacturing costs involved – which poses a challenge in making them…
When cutting materials, high temperatures occur at the site of the cut that can negatively affect the cut and the workpiece, as well as shortening the tool’s…
Over the coming years there is a legal commitment for all the countries of Europe to improve the energy efficiency of buildings, which boils down to…
The amount of computer processing power needed for a robot to sense a gust of wind, using tiny hair-like metal probes imbedded on its wings, adjust its flight…
A team at Caltech has figured out a way to encode more than one holographic image in a single surface without any loss of resolution. The engineering feat…
Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while…
