Dynamic Cap‐Mediated Substrate Access and Potent Inhibitor Design of Monkeypox Virus I7L Protease

Advanced Science, EarlyView.
The first crystal structure of MPXV I7L protease, revealing its unique dimeric form is resolved. The structures and MD simulations uncovered a dynamic cap region that regulates substrate access to the active site. The structural basis of substrate recognition and the catalytic mechanism are elucidated, which led to the development of a FRET‐based assay

Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

Trimerization of 1,2‐Diaminocyclohexane Catalyzed by a Metal–Organic Cage Tandem Catalyst with Dual Biomimetic Active Sites

Advanced Science, EarlyView.
Dual biomimetic active sites, i.e., mononuclear {ZnII(L)(H2O)} and dinuclear {L2ZnII(CHO2)(OH)ZnIIL2}, have been successfully intergrated into a metal–organic cage, Zn20‐MOC. These two different active sites in Zn20‐MOC catalyze different steps of cascade trimerization of 1,2‐diaminocyclohexane. The mononuclear {ZnII(L)(H2O)} site catalyzes the initial

Spontaneous Strain‐Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High‐κ and Switchable Dielectric Permittivity

Advanced Science, EarlyView.
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Recycling Defunct Lithium‐Ion Battery Cathodes to Quaternary Layered Double Hydroxides for Efficient Oxygen Evolution Reaction

Advanced Science, EarlyView.
Li(Co0.8Ni0.1Mn0.1)O2 and LiFePO4 cathode materials are functional recycled by simple leaching and co‐precipitation methods to synthesize Quaternary iron‐nickel‐cobalt‐manganese hydrotalcites as oxygen‐evolution‐reaction catalysts. The highly disordered structure and strong electronic interactions between metal cations result in excellent catalytic ...

Electronic Microenvironment Regulation of Bismuth‐salophen Single‐site Catalysts for Enhanced Selectivity in CO2 Electrolysis to Formic Acid

Advanced Science, EarlyView.
The microenvironment modulation of Bi SSCs via electronegative group (─F/─H/─OMe) modification demonstrably suppresses the HER at high current densities, achieving a HCOOH FE of 95%. The ─F group optimizes the electronic structure of Bi, significantly enhancing CO2 adsorption and reducing the energy barrier for *OCHO intermediate formation, thereby ...
