When traversing a solid material such as glass, a light wave can deposit part of its energy in a mechanical wave, leading to a color change of the light. This process called “Brillouin scattering” has important technical applications.
DNV GL has been contracted by PUB, Singapore’s national water agency, as technical advisor for the 50 MW floating solar photovoltaic (PV) project at the Tengeh Reservoir in Singapore. Once completed, the floating solar project will be one of the largest single floating solar systems in the world.
Edmund Optics® (EO), the premier provider of optical components, is proud to announce several additions to its product lineup, including Hexa-Black™ C-Mount Noise Reduction Extension Tubes, TECHSPEC® CA Series Fixed Focal Length Lenses and Low GDD Ultrafast Mirrors.
In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice the energy needed to do so.
Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom wherever it is found. A hydrogen atom in outer space absorbs light at the same energies as one on Earth.
Material developed at MIT can passively capture solar heat for home heating or industrial applications.
Jigang Wang patiently explained his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentioned light-induced superconductivity without energy gap. He brought up forbidden supercurrent quantum beats. And he mentioned terahertz-speed symmetry breaking.
Scientists from the University of Bristol and the Technical University of Denmark have found a promising new way to build the next generation of quantum simulators combining light and silicon micro-chips.
Leaders in the field of ultracold molecule research from Columbia and Harvard Universities are teaming up to propel understanding of the quantum mechanics of chemical reactions.
Thin-film solar panels, the cell phone in your hand and the LED bulb lighting your home are all made using some of the rarest, most expensive elements found on the planet.
