New work on the chemical and crystallographic heterogeneities present in a Ni/NiO-YSZ solid oxide fuel cell electrode after re-oxidation

In our latest work, we look with at the chemical and crystallographic heterogeneities present in a Ni/NiO-YSZ solid oxide fuel cell electrode after re-oxidation. The research was carried out in collaboration with Dr Thomas Heenan from the Electrochemical Innovation Lab (EIL) at UCL Chemical Engineering, UCL Chemistry and ESRF. The solid oxide fuel cell (SOFC) anode […]

Methane activation via integrated Membrane Reactors – project results

The results of our MEMERE project show novel membranes and catalysts reduce greenhouse gas emissions in chemical industry The production of ethylene (C2H4) is one of the largest carbon dioxide (CO2) emitting industries in Europe. We have worked with EU-funded researchers to develop a cost-efficient, environmentally friendly process that produces higher yields than current technologies […]

Dr. Antony Vamvakeros webinar on X-ray diffraction computed tomography July 21 – available to watch online

Synchrotron X-ray diffraction computed tomography (XRD-CT) is a marriage between powder diffraction and computed tomography using a “pencil” beam approach. The spatially-resolved signals obtained with XRD-CT can reveal information that would otherwise be lost in bulk measurements, which opens up new possibilities in functional material characterization. In this webinar, our research scientist Dr. Antony Vamvakeros […]

Watch Webinar from Prof. Andrew Beale on studying catalytic materials with intense radiation sources

Our Chief Scientific Officer Prof. Andrew Beale gave a webinar for the UK Catalysis Hub discussing opportunities for studying catalytic materials with intense radiation sources; what, where, when and how. It was in 1836 that Jöns Jacob Berzelius provided the first, basic description of a catalyst and its properties. Both the breadth and depth of […]
