Chemists have discovered a way to use visible light to synthesize a class of compounds particularly well suited for use in pharmaceuticals. The class of compounds, called azetidines, had been ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

During the past 15 years, an increasing number of research groups have embraced visible-light-mediated synthetic transformations as a powerful strategy for the construction and functionalization of ...

This Review aims to highlight the developments in the field of visible-light-mediated enantioselective photocatalysis utilizing bifunctional organic photocatalysts by giving an overview of the ...

Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases an ultraweak glow, a stream of photons that appears to switch off when life ...

From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...
