Journal ArticleDOI
Rethinking Arsenate Coordination at the Surface of Goethite
TL;DR: The cumulative results show that arsenate coordinates at the water-goethite interface in a predominately monodentate fashion and find no evidence for bridging-bidentate coordination, which is a finding that impacts oxoanion bioavailability and challenges theories of mineral dissolution and surface complexation.
Journal ArticleDOI
Scrutinizing negative thermal expansion in MOF-5 by scattering techniques and ab initio calculations.
Nina Lock,Mogens Christensen,Yue Wu,Vanessa K. Peterson,Maja K. Thomsen,Ross O. Piltz,Anibal J. Ramirez-Cuesta,Garry J. McIntyre,Katarina Norén,Ramzi Kutteh,Ramzi Kutteh,Cameron J. Kepert,Gordon J. Kearley,Bo B. Iversen +13 more
TL;DR: A uniform and comprehensive picture of NTE in MOF-5 has been drawn, and it is provided direct evidence that the main contributor to NTE is translational transverse motion of the aromatic ring, which can be dampened by applying a gas pressure to the sample.
Journal ArticleDOI
The influence of the local structure of Fe(III) on the photocatalytic activity of doped TiO2 photocatalysts—An EXAFS, XPS and Mössbauer spectroscopic study
Éva G. Bajnóczi,Nándor Balázs,Károly Mogyorósi,Dávid Ferenc Srankó,Zsolt Pap,Zoltán Ambrus,Sophie E. Canton,Katarina Norén,Ernő Kuzmann,Attila Vértes,Zoltán Homonnay,Albert Oszkó,István Pálinkó,Pál Sipos +13 more
TL;DR: In this article, Fe-K edge X-ray absorption measurements were performed to quantify these effects, and it was learned that Fe(III) was present in a distorted octahedral environment in both series, however, the extent of distortion is much more significant within the S than within the F one.
Journal ArticleDOI
An X-ray absorption near-edge structure (XANES) study of the Sn L3 edge in zirconium alloy oxide films formed during autoclave corrosion
Helen Hulme,Felicity Baxter,R. Prasath Babu,Melissa A. Denecke,Mhairi Gass,Axel Steuwer,Katarina Norén,Stefan Carlson,Michael Preuss +8 more
TL;DR: The application of Sn L3-XANES to study the oxidation state of alloying additions of tin (1-1.2wt%) in this paper was described in Section 2.
Journal ArticleDOI

TL;DR: In this paper, structural and morphological characterizations of bimetallic Pd-Pt/Al2O3 model catalysts were performed using X-ray diffraction, Xray absorption spectroscopy, transmission electron microscopy, and CO chemisorption.
