When a laser experiment fails to produce the expected flash of light, most researchers would assume something went wrong with ...

Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using ...

Liquids and solutions may look simple, but on the molecular scale they are constantly shifting and reorganizing. When sugar dissolves in water, each sugar molecule quickly becomes surrounded by fast ...

Researchers at the University of California, Santa Cruz, have reported the first observations of ultrafast electronic dynamics in a system of strongly interacting gold nanoparticles. The observations ...

Bringing ultrafast physics to structural biology has revealed the dance of molecular ‘coherence’ in unprecedented clarity. How molecules change when they react to stimuli such as light is fundamental ...

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is ...

The top panel illustrates halide substitution in cesium lead halide (CsPb(Br/Cl)₃) nanocrystals, where photoirradiation induces exchange between bromide and chloride ions, altering the Br/Cl ratio.

(Nanowerk News) How molecules change when they react to stimuli such as light is fundamental in biology, for example during photosynthesis. Scientists have been working to unravel the workings of ...
