Structural and Chemical Dynamics of Cu/NiO/Cu(100) Surfaces During CO2 Hydrogenation

Angewandte Chemie International Edition, EarlyView.
Dynamic segregation as a design principle for Cu–Ni catalysts. Operando LEEM/XPEEM tracks reduction, reshaping, and surface segregation processes taking place in Cu‐encapsulated NiO islands supported on Cu(100) during CO2 hydrogenation. ABSTRACT Understanding the dynamic restructuring of bimetallic catalysts under reaction conditions is key to ...

Ferroelectric control of magnetism in artificial multiferroic composites [PDF]

, 2015
In this thesis, we studied ferromagnet/ferroelectric heterostructures, so-called artificial multiferroic composites, which exhibit magnetoelectric coupling between different ferroic order parameters. For a range of material combinations, we found that

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Straintronics and Twistronics in 2D Materials: Structural Control and Predictive Design

Small, EarlyView.
Strain and twist engineering in 2D materials is established as a programmable design parameter responsible for reconstructing lattices, tuning interlayer coupling, and developing new quantum functionalities. Through the integration of advanced fabrication techniques, multiscale characterization, computational modeling, and machine learning, this review

Homologous Fatty Acid Additives for Simultaneous Corrosion Suppression and Zn2+ Transport Enhancement in Aqueous Zinc‐Ion Batteries

ChemElectroChem, Volume 13, Issue 19, 1 October 2026.
Aqueous zinc‐ion batteries are viable for grid‐scale storage. Dendrites, corrosion, and hydrogen evolution hinder their deployment. Sodium salts of medium‐chain fatty acids (C12–C14) are chosen as electrolyte additive. They block side reactions while sustaining Zn2+ transport.

An all‐polymer blend for photovoltaic applications: A combined photoabsorption, photoemission and ab initio multi‐configurational study

Polymer International, Volume 75, Issue 10, Page 983-992, October 2026.
Near‐edge X‐ray absorption fine structure, X‐ray photoelectron spectroscopy and multi‐configuration self‐consistent field results show, respectively, preferential edge‐on and face‐on orientations for the thiophene and naphthalene diimide units of the PBDB‐T‐SF:P(NDI2OD‐T2) all‐polymer blend, and surface accumulation of the acceptor.
