Advanced Functional Materials, EarlyView.In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction
Advanced Functional Materials, EarlyView.This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Advanced Functional Materials, EarlyView.Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...

Proton transport in water is doubly gated by sequential hydrogen-bond exchanges [PDF]
The transport of excess protons in water is central to acid-base chemistry, biochemistry, and energy production. However, elucidating its mechanism has been challenging.

Hydrogen-Bond Mediated Catalysis: The Aminolysis of 6-Chloropyrimidine as Catalyzed by Derivatives of Uracil [PDF]
, 2016 The aminolysis of 6-chloropyrimidine and 2-amino-6-chloropyrimidine has been examined by using density functional theory. Relative to the aminolysis of 6-chloropyrimidine, the addition of an electron-donating NH2 group to C2 increases the barrier to ...

Low‐Barrier and Canonical Hydrogen Bonds Modulate Activity and Specificity of a Catalytic Triad
Angewandte Chemie, 2019 AbstractThe position, bonding and dynamics of hydrogen atoms in the catalytic centers of proteins are essential for catalysis. The role of short hydrogen bonds in catalysis has remained highly debated and led to establishment of several distinctive geometrical arrangements of hydrogen atoms vis‐à‐vis the heavier donor and acceptor counterparts, that is,
