Catalysis, Electrochemical XPS

Dr. Mark Isaacs
Researcher and Experimental Officer

I have been working with XPS for over 10 years, starting out as a PhD student under the supervision of Profs. Karen Wilson and Adam Lee at Cardiff University. Since then I've been fascinated with how to use XPS to obtain new and different information for nanocomposites, particularly porous architectures. My research involves developing new XPS techniques, ex- and in-situ, to inform novel nanomaterial design. Interests: Porous materials, Multi-technique analysis, Operando/In-Situ XPS, Catalysis, Antibacterials, CryoXPS

Dr. Josh Davies-Jones

Researcher in Cryogenic XPS and photo-induced force microscopy (PiFM) at Harwell XPS, studying surface chemistry and bonding in microbes and plastics for applications in diagnostics and antimicrobial resistance. Specializes in developing methods for the analysis of complex samples and the growth mechanisms of nanoparticles. Interests: CryoXPS, Microplastics, Microbiology, PIFM, Catalysis

Dr. Arthur Graf

I have been working with surface chemistry since undergraduate alongside prof Rocco in Brazil, where I have fallen in love with spectroscopy. As standard in the HarwellXPS team, I am very enthusiastic when it comes to XPS and XAS techniques, their uses and instrumentation. My research interests focus on spectroscopy of inorganic nanomaterials - Janus Particles, quantum dots and thermochromics. More recently I have been using the Cryo-XPS to analyse sensitive inorganic systems (including explosive materials). TAGS: Surface Chemistry, temperature-controlled XPS, inorganic nanoparticles, PiFM

Charalampos Drivas

I have been working with surface and interface analysis by UPS and XPS since 2016, during my MEng and PhD at the University of Patras, Greece under the supervision of prof. S. Kennou and S. Ladas. I am very keen on investigating the interaction between the substrate and the adlayer regarding the interface properties and how these affect their application. Interests: Operando/In-situ XPS & UPS, Interface analysis, Charge transfer, 2D materials, Semiconductors

Ben Spencer
Faculty Lead - HAXPES

Ben is faculty lead for Surface Analysis at the University of Manchester and also works within the Henry Royce Institute for Advanced Materials. Since 2019 he has led development of laboratory-based hard X-ray photoelectron Spectroscopy (HAXPES) with a first-of-its-kind instrument from Scienta Omicron GmbH, part of Royce as well as HarwellXPS. His research spans a variety of advanced materials research particularly energy materials including photovoltaics. Ben is a committee member in the IoP Materials and Characterisation special interest group.
