Ni-based catalyst for dry reforming of methane with high stability

Wei WANG · Wei ZHOU · Charles SIDHOUM · Vadim DIADKIN · y 2 más

Ni-based catalysts have garnered significant interest in the dry reforming of methane (DRM) due to their cost-effectiveness and notable activity. Via the surface organometallic chemistry (SOMC) method, which has emerged as a powerful tool to synthesize well-defined model catalysts for an array of reactions, we have syn...

High-resolution X-ray absorption spectroscopy for improved management of critical-metal geo-resources: probing the gold-thallium coupling in

Grégory CIULLA · Marc BLANCHARD · Gleb POKROVSKI · Mauro ROVEZZI

Pyrite is the major sulfide mineral on Earth hosting a plethora of precious and critical trace metals. They are often coupled with thallium that might act as ore pathfinder. On the other hand, the presence of Tl, a harmful pollutant, strongly devaluates sulfide ore and poses environmental threat. To manage such metal r...

EuXFEL-CFEL collaboration BAG for TR-SSX

Dmitrii ZABELSKII (ORCID: 0000-0001-6906-975X) · Thomas LANE · Esther Rosalie LANGE · Volha CHUKHUTSINA · y 3 más

Beamline ID-29 offers unique opportunities for time-resolved structural biology in the microsecond regime and - because of the small focus - for the use of small crystals for e.g. faster diffusion of ligands. We will combine in this BAG research interests from groups from CFEL and EuXFEL, that span from methods develop...

Coupling oxidation state and catalyst stability during pulsed electrochemical CO2 reduction via operando X-ray absorption spectroscopy

Alessandro SENOCRATE · Davide SALUSSO · Finn BEIGLBOECK · Francesco BERNASCONI

Electrochemical CO2 reduction (eCO2R) is a promising pathway to convert detrimental CO2 emissions into sustainable chemicals. The use of gas diffusion electrodes (GDEs) fed by gaseous CO2 enables achieving high activity and selectivity, albeit with limited stability. We recently demonstrated by operando wide-angle X-ra...

Simultaneous Estimation and Dataset Selection for Transfer Learning in High Dimensions by a Non-convex Penalty

Li, Zeyu · Liu, Dong · He, Yong · Zhang, Xinsheng

In this paper, we propose to estimate model parameters and identify informative source datasets simultaneously for high-dimensional transfer learning problems with the aid of a non-convex penalty, in contrast to the separate useful dataset selection and transfer learning procedures in the existing literature. To numeri...

Exploring the interaction mechanisms of extracellular vesicles with model membranes

Paola BROCCA · Sally Helmy ABDALLA · Valeria Maria RONDELLI · Lorenzo DAL FABBRO · y 2 más

Owing to the content of the Extracellular Vesicles (EVs), they can target their cargoes to control and mediate the intercellular communications by both paracrine and endocrine mechanism. Yet, their exact interaction mechanism is not yet fully elucidated. Therefore, we address this by a multi-technique approach, using m...

Nitridation and catalytic performance of metal oxides in low-temperature NH3 decomposition

Magnus RONNING · Alicia SAN MARTIN RUEDA · Kenneth MARSHALL · Sahra Louise GULDAHL-IBOUDER · y 1 más

This proposal aims to investigate the effects of nitridation on the structural transformation of mixed metal oxides, and to determine how structural and electronics changes relate to catalytic activity during ammonia decomposition. We will compare the structural modifications and catalytic properties of supported and n...

Study of the local structure of 2D chiral perovskites

Camilla FERRARI · Margherita GARBACCIO · Lorenzo MALAVASI · Marco MORONI · y 1 más

Chiral metal halide perovskites are emerging as important materials for non-linear optical properties and spin-related phenomena due to their chiroptical and chiro-spintronic properties. To date several chiral perovskites have been prepared and characterized but the exact mechanism of chiral transfer is still elusive a...
