Warwick Christmas Lectures 2019

As part of the Warwick Christmas Lectures 2019 we held an optics-packed pre-show, featuring demos about some of the weird and wonderful properties of light. Members of the Physics Department and Ultrafast & THz group explained important phenomena like fluorescence, infrared light, polarisation and diffraction and more! The "twangs" of the Department's laser harp helped provide some festive music. There were 1100 members of the public at the lecture, a lot of whom made it to the pre-show science bonanza. On stage James talked about the power of lasers, ably assisted by Edward the Elf (below). Thanks to everyone who helped make the Christmas Lecture on 26th Nov such as success! More pictures here...

WCUS collaborates in new anti-cancer work, published in Nature Chemistry

New research published last week in Nature Chemistry demonstrates a novel highly oxidative Ir(iii) photocatalyst, which is phototoxic towards both normoxic and hypoxic cancer cells.This research was a large collaborative project between groups in China, Switzerland, France, and the UK. WCUS contributed time resolved phosphorescence data to the study, which demonstrated an extremely long phosphorescence lifetime of the photocatalyst, thus leading to a very high oxidation turn over number making it a very effective anti-cancer agent.
