XAS probing the redox mechanism and the role of transition metals in O3-type layered oxide cathodes for sodium-ion batteries

Blanka DETLEFS (ORCID: 0000-0002-9768-647X) · Rishikesh VENGARATHODY · Yang HU · Soutam PANJA

This project focuses on O3 type layered transition-metal oxide cathodes Na0.9Mn0.48Fe0.3(Cu/Zn)0.22O2 for Na-ion batteries. We aim to probe the transition metals on their cycling-induced evolutions in redox activity and local structure by synchrotron operando XAS. We expect to distinguish the role of these TMs in the o...

Tracing the evolution of Lathrobium: A phylogenomic approach using museum specimens

Alexandra Tokareva · Aslak Kappel Hansen · Dagmara Żyła

Megadiverse insect lineages often lack robust phylogenetic frameworks, limiting our ability to understand the processes underlying their diversification and morphological evolution. The rove beetle genus Lathrobium (Staphylinidae: Paederinae), with nearly 800 described species distributed primarily across the Holarctic...

The threshold phenomena for propagation in fractional Laplacian diffusion equations

Faye, Grégory · Zhao, Min

In this paper, we investigate the threshold phenomenon between extinction and propagation in fractional Laplacian diffusion equations for a class of compactly supported initial data. We provide the first quantitative estimates on the threshold when the reaction nonlinearity is of bistable or ignition type. We mainly us...

Optimal market-aware scheduling and control of EV batteries in second-life usage

Maria-Eleni Peponi · Matthieu Jacobs · Vladimir Sovljanski · Mario Paolone

As the share of renewable energy in power systems increases, the resulting need for additional flexibility can be supported by second-life battery energy storage systems. However, their operation is complicated by the heterogeneity of the constituent battery packs. This paper addresses this challenge by proposing an op...

Belgium BAG

Anmol GAUTAM · Sergei STRELKOV · Thibault VANTIEGHEM · Evgenii OSIPOV · y 2 más

The Belgium BAG includes groups situated at four Flemish universities: Antwerpen, Brussels, Ghent and Leuven. The proposed projects are highly diverse, including viral, prokaryotic and eukaryotic proteins with a strong focus on targets and processes of biomedical relevance. Many projects deal with membrane proteins, ce...

Adsorbate-induced phenomena at Pt- and Ru-based catalysts in liquid phase

Alberto RICCHEBUONO · Daniele BONAVIA · Kirill LOMACHENKO · Paolo LAZZARINI · y 4 más

The aim of this proposal is to investigate H2 and CO-induced phenomena occurring at Pt- and Ru-based catalysts by time-resolved XAS experiments in the liquid-phase. Previous multi-technique experiments, comprising Pt L3-edge XAS (CH-5204), revealed that Pt nanoparticles (NPs) restructure in the presence of H2 in the ga...

Very Long-Distance MLL Development and in-situ & in-operando Setups for X-ray Nanodiffraction Analysis of Thin Films and Energy Components

Kevin KUTLESA · Francois LIENARD (ORCID: 0000-0001-6825-454X) · Peter GAWLITZA · Sven NIESE · y 3 más

The project focuses on the development of multilayer Laue lenses (MLLs) for ID13. Previous experiments have already shown focal spot sizes down to ~23 nm with diffraction efficiencies up to about 29 %. The main instrumental goal of this LTP is the development of two types of MLL optics, namely (i) “very long-distance”...

Uniqueness result for semi-linear wave equations with sources

Qiu, Dong · Xu, Xiang · Ye, Yeqiong · Zhou, Ting

This paper addresses the inverse problem of simultaneously recovering multiple unknown parameters for semilinear wave equations from boundary measurements. We consider an initial-boundary value problem for a wave equation with a general semilinear term and an internal source. The inverse problem is to determine the non...

Gastroprotective effect of Daphniphyllum calycinum Benth.–Polygonum hydropiper L. against gastric mucosal injury through autophagy activation and apoptosis suppression

Yunyun, Zhi · Jiayi, Ou · Dexin, Wu · Keli, Zhou · y 3 más

Gastric mucosal injury, commonly induced by ethanol and psychological stress, represents a significant clinical challenge with limited natural therapeutic options. The Li ethnic herbal pair consisting of Daphniphyllum calycinum Benth. and Polygonum hydropiper L. (DCPH), commercially available as Fengliao Changweikang G...
