A technique to combine the ultrasensitivity of surface enhanced Raman scattering (SERS) with a slippery surface will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
Scientists offer a more generalized theoretical description of chemical potential (usually denoted by the Greek letter mu) for light and show how mu can be controlled and applied in a number of physics research areas.
Scientists took a different approach to the PEC process, which uses solar energy to split water into hydrogen and oxygen. The process requires special semiconductors, the PEC materials and catalysts to split the water.
Computer simulations that predict the light-induced change in the physical and chemical properties of complex systems, molecules, nanostructures and solids usually ignore the quantum nature of light. Scientists have now shown how the effects of the photons can be properly included in such calculations.
Everyone expects objects at the atomic scale to follow the weird rules of quantum mechanics. But in the past few years, scientists have shown that comparatively large mechanical objects can be coaxed into exhibiting a surprising variety of quantum properties.
