For the first time, scientists have captured how complex molecules change shape when exposed to UV light—an ultra-fast ...

Tiny molecules that can change their shape ... that bend in response to visible wavelengths of light and revert back in the presence of UV light. “We were inspired by the way bacteria propel ...

But state-of-the-art ultraviolet and visible (UV-vis) spectrophotometry, which measures electronic transitions of a wide range of molecules as they absorb light, was cumbersome and expensive. In July ...

can utilize circularly polarized luminescence (CPL), which is produced when specific types of molecules are irradiated with UV light. The electric field of the CPL rotates in a spiral shape.

Since these are photoresponsive molecules, when the stacked helical structures are exposed to weak ultraviolet (UV) light, the helical assembly disassembles back into individual molecules ...

Here's how these UV light sanitizers actually work. UV light is highly effective at killing germs The three main types of UV rays are UVA, UVB, and UVC. Because UVC rays have the shortest ...

But his latest isn’t only about 3D printing. He shows how he uses a DLP printer — which has UV light, after all — to expose PC board blanks with great results. Honestly, once we heard the ...

Because certain biological molecules are capable of molecular recognition and ... are promising for applications in lighting systems (warm white light without UV and infrared irradiation) and high ...
