First chemical imaging study on 3D printed catalysts used for CO2 methanation

Finden scientists new work on the characterisation on 3D printed catalysts has been published in a new paper, “3D printed Ni/Al2O3 based catalysts for CO2 methanation – a comparative and operando XRD-CT study” in the Journal of CO2 Utilization. The X-ray chemical imaging work was performed with Vesna Middelkoop from the Flemish Institute for Technological […]

New work on sustainable iron-based oxygen carriers for hydrogen production published

Finden Ltd collaborated with Yoran De Vos (Ghent University) to look at the evolution of an Fe-based oxygen carrier under operando conditions. The project has resulted in a paper published in the International Journal of Greenhouse Gas Control titled, “Sustainable iron-based oxygen carriers for hydrogen production – Real-time operando investigation.“ In this work, a spray-dried […]

Our paper on the first X-ray diffraction tomography experiment of real-life size micro-tubular SOFC has been published in Nature Communications

Our new work on a state-of-the-art SOFC has been published in a paper “Design of next-generation ceramic fuel cells and real-time characterization with synchrotron X-ray diffraction computed tomography“ in Nature Communications. Solid oxide fuel cells offer a clean and efficient means of producing electricity through a variety of fuels. However, miniaturization of cell dimensions for […]

Operando and Postreaction Diffraction Imaging of the La–Sr/CaO Catalyst in the Oxidative Coupling of Methane Reaction

Our paper on Operando and Postreaction Diffraction Imaging of the La–Sr/CaO Catalyst in the Oxidative Coupling of Methane Reaction has been published online by The Journal of Physical Chemistry. A La–Sr/CaO catalyst was studied operando during the oxidative coupling of methane (OCM) reaction using the X-ray diffraction computed tomography technique. Full-pattern Rietveld analysis was performed […]

Tomographic software nDTomo released!

The nDTomo software is now publicly available for download. Developed by our research scientist Dr. Antony Vamvakeros and primarily designed for processing XRD-CT data, it can be used for other tomographic techniques as well. The software suite contains GUIs for the acquisition, pre-processing and analysis of X-ray chemical tomography data. Download it at https://github.com/antonyvam/ndtomo

A masterpiece on a on a pin head

Finden Ltd’s work with microfocus X-ray beams at Diamond Light Source recently appeared in an article in The Telegraph, “Old Master paintings shown to be ‘crusting over’ by microscope 10 billion times brighter than the Sun.” Dr. Stephen Price explains in the article, “We were able to plot the different chemistry from the surface down […]

Prof. Andrew Beale discusses our recently published paper on 5D diffraction imaging in his Behind the Paper article – Chemistry in multiple dimensions

Solid catalysts are used in almost every field of the chemical industry, ranging from pharmaceuticals to petrochemicals as well as the automotive industry, to produce the desired products. These catalytic solids usually comprise complex 3D structures which can be inhomogeneous. In recent years, it has been realised that it is crucial to investigate these materials […]

5D operando tomographic diffraction imaging of a catalyst bed

Our paper on 5D operando tomographic diffraction imaging of a catalyst bed has been published online by Nature Communications, volume 9, Article number: 4751 (2018) We report the results from the first 5D tomographic diffraction imaging experiment of a complex Ni–Pd/CeO2–ZrO2/Al2O3 catalyst used for methane reforming. This five-dimensional (three spatial, one scattering and one dimension to denote time/imposed […]

3D Printed Catalysts

Finden Ltd’s techniques for 3D imaging computed tomography appeared in the September 2017 edition of Chemistry World, in the article titled, “Diamonds are forever” which can be found at Chemistry World: Here is an extract from the article which explains the techniques Professor Andrew Beale, Chief Scientific Officer at Finden Ltd uses, “Principal beamline scientist […]
