NEW PDRA Position

Applications are invited for a full-time Research Associate position that will investigate the electrochemical recycling of lead-acid batteries using deep eutectic solvents (DESs). This proposed project aims to develop a new electrochemical route to secondary lead production, using deep eutectic solvents to decrease the energy consumption of a typical secondary lead smelting plant. Please emailo me for further details.


We are looking to fill a PhD studentship with an outstanding candidate. There are two projects:

(1) High-pressure photoelectron spectroscopy of water on surfaces. This project will utilise the newly commissioned and world-leading HiPPES instrument and focus on the manipulation of and measurement of water on metal surfaces. This has important applications in solar-driven surface chemistry and corrosion.

(2) The new physics of iridium oxides. This project will focus on the determination and understanding of the complex electronic structure of iridium oxides. These materials have been shown to display exotic physics, which culd find use in next generation "quantum" electronic devices. The project will include the synthesis and characterisation of novel iridates using state-of-the-art spectroscopies at synchrotrons worldwide.

The research of the group focuses on the investigation of the surface chemistry and electronic structure materials, using state-of-ther-art photoelectron spectroscopy. 

A range of spectroscopic techniques have been employed including soft and hard x-ray photoelectron spectroscopy (XPS and HAXPES), x-ray emission and absorption (XES and XAS). These experiments have been performed at a number of national and international synchrotron radiation facilities including the ALS (Berkeley, U.S.A.), Diamond (Harwell, U.K.), Elettra (Trieste, Italy), ESRF (Grenoble, France), Max-Lab (Lund, Sweden), NSLS (Brookhaven, U.S.A.). High-resolution XPS has also been performed at NCESS (Daresbury, U.K.). The materials under investigation have been synthesized using different methods. Single crystalline thin films are produced using oxygen plasma assisted beam epitaxy (OPABE) in ultra-high vacuum (UHV) conditions. X-ray diffraction (XRD) (synchrotron- and lab-based), atomic force microscopy (AFM), high- resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM) are all used to characterize the films. Underpinning the work done in UHV, more conventional methods of solid state synthesis are undertaken to produce ceramic samples.
