Hard Carbon Networks for Mitigating Graphite Lattice Strain Under Extreme‑Low‑Temperature Fast Charging

ABSTRACT Low‐temperature fast charging of lithium‐ion batteries is primarily constrained by sluggish reaction kinetics and mechanical degradation of graphite anodes. Here, a kinetic–structural coordination strategy based on a 15 wt.% hard carbon (HC) percolating network embedded...

Halogen Substitution as a “Chirality Editor” for Amplifying Spin‐Selective Transport in Lead‐Free Metal‐Halide Hybrids

ABSTRACT Lead‐free metal‐halide hybrids hold promise as flexible semiconductors for X‐ray detection, but their application is constrained by inefficient carrier transport. Here, we introduce halogen substitution on chiral molecular cations as a “chirality editor” to modulate the...

DiastereoselectiveAddition of Racemic α-BorylOrganozinc Reagents to Aldimines

Abstract The addition of alkylzinc reagents to imines is a key route to amines, but suffers from poor selectivity when racemic secondary alkylzincs are employed. Herein, we report a transition-metal-free diastereoselective addition of racemic α-boryl organozincs to aldimines, aff...

A Dragonfly Wing-InspiredMXene-Reinforced Soy ProteinAdhesive with Balanced Strength, Toughness, and Multifunctionality

Abstract Replacing petroleum-derived wood adhesives with soy protein isolate (SPI) offers a sustainable alternative, yet the practical application of SPI is severely hindered by its intrinsic poor water resistance and mechanical fragility. To overcome these drawbacks, we develope...
