Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

open access: yesAdvanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Augmenting migration statistics with expert knowledge [PDF]

open access: yes
International migration statistics vary considerably from one country to another in terms of measurement, quality and coverage. Furthermore, immigration tend to be captured more accurately than emigration.

Fast‐Charging Phosphorus Anodes Enabled by Fluorinated Weakly Solvated Electrolytes for Stable and High‐Rate Lithium Storage

open access: yesAdvanced Materials, EarlyView.
A universal weakly‐solvated electrolyte design principle is established for phosphorus‐based anodes through systematic evaluation. Based on this criterion, the fluorinated solvent of FEC emerges as the optimal co‐solvent, effectively suppressing the dissolution of lithium polyphosphides while enhancing desolvation/charge‐transfer kinetics and ...

Regional international migration distribution in Spain: which factors are behind? [PDF]

open access: yes
International migration issues are at the forefront of the political debate in the European Union (EU). Some reasons justify the increasing relevance of this topic, being the unprecedented scale of international migration flows, especially in countries ...

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.
