Electron Bridge Enhanced Charge Polarization Enables Efficient and Ultra‐Long Stable Urea Electrosynthesis

open access: yesAngewandte Chemie, EarlyView.
An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

Methane Activation by B5+ Toward a CB5H2+ Isomer Containing a Planar Tetracoordinate Carbon Atom

open access: yesAngewandte Chemie, EarlyView.
Methane activation by B5+ yields CB5H2+ through H2 elimination. Electronic‐structure calculations connect the nascent dehydrogenation product to a low‐lying isomer containing a planar tetracoordinate carbon atom. ABSTRACT Planar tetracoordinate carbon (ptC) motifs have been identified predominantly in the global‐minimum structures of gas‐phase clusters

Chemical Synthesis and Functional Screening of an 800 000‐Member Library Using a Peptide‐Pairing Strategy

open access: yesAngewandte Chemie, EarlyView.
Chemical peptide synthesis allows the generation of structurally highly diverse compounds suited for ligand development, but current methods in parallel peptide synthesis limit the achievable library size to a few thousand. A strategy is presented based on combinatorial pairing of short peptides via disulfide linkage that enables the generation and ...

Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

open access: yesAngewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.
