Funded PhD positions available in Physics
Funded PhD positions are available to work with Emma MacPherson on "Fast Terahertz Imaging and Spectroscopy", and with James Lloyd-Hughes on "Ultrafast terahertz spectroscopy of novel perovskite photovoltaics". Please get in touch if you are interested in a PhD or MSc by Research in the group. These are funded studentships lasting 3.5 years, and are available to UK and EU students. For more details please see the Physics Postgraduate admissions page.
IR beamline aces reproducibility
The IR beamline has been undergoing rigourous refining and further testing and has beautifully reproduced data from published results. See the results gallery to view this new exciting data of N-methyl pyridone in ACN excited at 267 nm.

First Step toward a Universal Fluorescent Probe: Unravelling the Photodynamics of an Amino–Maleimide Fluorophore
Michael Staniforth, Wen-Dong Quan, Tolga N. V. Karsili, Lewis A. Baker, Rachel K. O’Reilly, and Vasilios G. Stavros
J. Phys. Chem. A, 121:6357 (August 2017)
WCUS and affiliates publish a brand new work in which we discuss fluorescence quenching in a small, single moleucle fluorophore, and how learning the mechanism of this quenching can aid us in future design of new fluorescent tags.
WCUS conference season - Optical Terahertz Science and Technology, UCL, 2-7th April.
WCUS members attended the Optical Terahertz Science and Technology meeting at UCL on 2-7th April, 2017. James lloyd-Hughes presented his findings on "Colossal terahertz magnetoresistance at room temperature in oxide nanocolumns."
