Such a device could be used for ultra-high-speed and high-resolution imaging in chemistry, biology, materials science and condensed matter physics. For example, in the life sciences, one could view images with resolutions clear enough to see individual carbon atoms, or to discern events such as a chemical reactions that last one quadrillionth of a second or shorter.

Read moreResearchers from NIST have established guidelines for using surface plasmon polaritons (SPPs) to improve absorption in both photovoltaic or photoelectrochemical cells used for energy conversion. In both types of photocells, SPPs have the potential to increase the amount of light absorbed in the active material layer, improving the overall efficiency of light collection in solar energy devices.
