Optimized Pt–Co/BN Catalysts for Efficient NaBH4 Hydrolysis

Advanced Energy and Sustainability Research, EarlyView.
The BOx shell protects bimetallic Pt–Co catalyst, where the BOx shell modulates the electronic properties of the Co–Pt active sites and the core–shell structure effectively prevents metal leaching, efficiently and stably produces hydrogen through sodium borohydride hydrolysis reaction.

Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction

Angewandte Chemie, EarlyView.
Organoautocatalyzed transamination metathesis of cyclic tertiary amines is disclosed as a high‐yielding, scalable reaction that proceeds under mild, catalyst‐free conditions. It operates via a multi‐step domino reaction mechanism, where an in situ‐formed pyrrolidinium salt functions as a HBD organoautocatalyst.

Crystallization of L‐Cysteine in Heavy Water Induces Intrinsic Fluorescence

Angewandte Chemie, EarlyView.
Crystallization of L‐Cysteine in D2O${\rm D}_2{\rm O}$ generates a remarkably different structure compared to H2O${\rm H}_2{\rm O}$. The crystals formed in D2O${\rm D}_2{\rm O}$ display enhanced intrinsic fluorescence, and using state‐of‐the‐art excited state simulations, we determine the molecular origins of this luminescence and propose design ...

Heterogeneous Photocatalytic Dehydrogenative Cross‐Coupling and Addition Reaction with Metal‐Loaded Titanium Oxide Photocatalysts

Advanced Energy and Sustainability Research, EarlyView.
Heterogeneous photocatalysis with metal‐loaded TiO2 photocatalysts under mild conditions can be utilized for various dehydrogenative cross‐coupling reactions, including the functionalization of aromatic rings via radical addition‐elimination or radical–radical coupling mechanisms, and the radical anti‐Markovnikov addition of alkenes. In some cases, the

Cooperativity of Electron Transfer Coupled Spin Transitions in a Tetranuclear Fe/Co Prussian Blue Analogue Revealed by Ultrafast Spectroscopy

Angewandte Chemie, EarlyView.
Ultrafast pump‐probe spectroscopies show that irradiation of a square Fe/Co Prussian blue analogue induces electron transfer within one Fe–Co subunit followed by fast spin crossover, and coupled equilibria between all states trigger a second electron transfer coupled to spin crossover in the other Fe–Co subunit on a ns timescale.

Construction of Active Sites‐Accessible Au8 Clusters for Intensive Tumor Pyroptosis

Aggregate, EarlyView.
Ethynylferrocene (EFc) was utilized to engineer molecular‐like gold nanoclusters (NCs) with accessibly catalytic centers, resulting in NCs exhibiting excellent peroxidase‐like activity and the ability to radiosensitize, leading to the production of intracellular oxidative stress and activation of pyroptosis.

Beyond Structure: Methylation Fine‐Tunes Stability and Folding Kinetics of bcl2Mid G‐Quadruplex

Angewandte Chemie, EarlyView.
The introduction of a single 5‐methylcytosine into a G‐rich sequence originating from the B‐cell lymphoma 2 (BCL2) gene promoter affects both the folding kinetics and thermodynamics of the two G4 structures and thus plays a crucial role in regulating G4 folding pathways, which has significant implications for the control of gene expression.
