Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Controlled Hydrogen Delivery by Single‐Atom Ru Accelerates Electrocatalytic Ammonia Synthesis

Angewandte Chemie, EarlyView.
Single Ru atoms anchored on Co3O4 guide reactants along a hydrogen‐rich surface pathway, enabling efficient and selective conversion of NO to NH3. By linking atomic design to catalytic performance, this strategy clarifies the reaction mechanism and offers a versatile platform for engineering oxide catalysts for electrochemical ammonia synthesis ...

Heavy‐Atom Tunneling at Room Temperature Revealed by Instanton Theory

Angewandte Chemie, EarlyView.
Usually, tunneling does not play a significant role in chemical reactions except at low temperature, especially when heavy atoms are involved. However, using nonadiabatic instanton theory we find that heavy‐atom tunneling dominates the reaction mechanism for spin‐forbidden processes in the synthesis of strained organic molecules even at room ...

Stable-isotope probing as a tool in microbial ecology

Microorganisms are responsible for driving the biogeochemical cycling of elements on Earth. Despite their importance and vast diversity(1), the taxonomic identity of the microorganisms involved in any specific process has usually been confined to that ...

Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

Angewandte Chemie, EarlyView.
Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

Template‐Encoded Assembly and Adaptive Function in Selenium‐Based Molybdenum Chalcoxide Rings

Angewandte Chemie, EarlyView.
External templates write structural information into Se‐containing molybdenum rings, while selenium's softness confers adaptive host–guest behaviour and catalytic responsiveness, an integrated framework for programmable inorganic function. ABSTRACT Controlling both structure and function in inorganic self‐assembly remains a major challenge.
