Angewandte Chemie, EarlyView.Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...

Advanced NanoBiomed Research, EarlyView.Beyond the green solvent paradigm, this review redefines Deep Eutectic Systems (DES) as programmable supramolecular nanoassemblies. We survey their biomedical convergence: stabilizing thermolabile mRNA to enable cold chain‐free logistics, reshaping transdermal microneedle delivery, enabling long‐term wearables via eutectogels, and utilizing Generative ...

Angewandte Chemie, EarlyView.Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Proglacial sedimentation of late Wisconsin age in Miers Valley, Antarctica [PDF]
, 2013 Miers Valley is an ice free valley in the Koettlitz Region of Victoria Land, Antarctica. The eastern basin of this valley has extensive coverage of gypsum and laminated calcite overlying fine silts and sands, while Lake Miers occupies the western basin ...

Angewandte Chemie, EarlyView.This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

Spin‐Polarized Interfaces Redirect CO2 Reduction From CO to Formate
Angewandte Chemie, EarlyView.The chiral electrocatalyst exploits the CISS effect to establish a spin‐polarized interface that selectively promotes formate production during CO2 reduction while effectively suppressing the competing hydrogen evolution. ABSTRACT Achieving high product selectivity in electrocatalytic carbon dioxide reduction (CO2RR) remains a critical challenge due to

Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation
Angewandte Chemie, EarlyView.The iron(III)‐peroxo complex [FeIII(O2)(12‐TMC)]+ exhibits bifurcating pathways in indole oxidation. N─H indoles undergo N─H H‐atom abstraction, supported by a KIE of 5.2 for N─H/N–D 2,3‐dimethylindoles, whereas N‐methylindoles react via electrophilic addition of the iron‐peroxo group to the C2–C3 double bond of the indole ring, forming iron ...

Angewandte Chemie, EarlyView.A series of oxoiron(IV) complexes was synthesized to determine the impact of electronically tuned aromatic substitution in the secondary sphere of the ligand. Despite possessing identical electronic properties, they show significant differences in C─H oxidation reactions.
