Lithium-ion batteries charge and discharge because their lithium ions can move in both directions between positive and negative electrodes. Lithium-ion batteries have generally been used in a compact ...

Detection of substances on the single-molecule level could provide a helpful too for pharmacology, medicine, and product safety. But toxic or otherwise unwanted substances sometimes have a low ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...

Surface reflectance is a measure of how much of the incident light is reflected by a given surface. For optical applications driven by the absorption of light, minimizing surface reflectance is ...
