Multiphoton upconversion that can convert near-infrared irradiation into ultraviolet emission offers many unique opportunities for photocatalysis and phototherapy. However, the high-lying excited ...

Attosecond time-resolved experiments have revealed the increasing importance of electronic correlations in the collective ...

using a chemical photocatalysis process powered by ultraviolet light. Professor Gunther Andersson, from the Flinders Institute for NanoScale Science and Technology, says the process involves ...
