A new type of "quasiparticle" theorized by Caltech's Gil Refael, a professor of theoretical physics and condensed matter theory, could help improve the efficiency of a wide range of photonic devices—technologies, such as ...
Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
The characteristic "rubber duck" shape of the comet carrying a European robot probe through space was the result of a low-velocity impact billions of years ago between two objects which fused, a study said Monday.
Every time you stroll outside you emit energy into the universe: Heat from the top of your head radiates into space as infrared light.
Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky for pitched rooftops and vehicle surfaces.
An international team of scientists has developed what may be the first one-step process for making seamless carbon-based nanomaterials that possess superior thermal, electrical and mechanical properties in three dimensions.
A luminescent solar concentrator is an emerging sunlight harvesting technology that has the potential to disrupt the way we think about energy; It could turn any window into a daytime power source.
A team of researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory developing a bioinorganic hybrid approach to artificial photosynthesis have achieved another milestone. Having generated ...
