Non‐Destructive Hydrophobic Engineering of Inverse Catalysts for Methanol Synthesis from CO2

Advanced Science, EarlyView.
In this study, we report a non‐destructive hydrophobic modification strategy for ZrO2/Cu catalyst through physical mixing with PDVB. The optimized ZrO2/Cu‐PDVB catalyst achieves a methanol space‐time yield of 920.10 mgCH3OH gcat−1 h−1 under mild conditions, outperforming the unmodified catalyst by 30 %.

Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

Advanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.

Trisoxazole Macrolides Potentiate the Microtubule Assembly and Antimitotic Activities of Taxanes

Angewandte Chemie, EarlyView.
Photoaffinity experiments identified tubulin as a new target of mycalolides. Though weakly cytotoxic, the trisoxazole macrolactone moiety enhanced paclitaxel's microtubule assembly and antimitotic effects. Molecular modeling studies suggested that MyC stabilizes α/β‐tubulin heterodimer interactions.

Ambient Hydrocarbonylation of Olefins Enabled by Visible‐Light

Advanced Science, EarlyView.
A novel photo‐induced methodology for hydrocarbonylation has been established, resolving the inherent conflicts between competitive olefin and CO insertion in traditional methods that necessitate harsh conditions. Accordingly, an efficient and versatile hydrocarbonylation of olefins enabled by visible‐light irradiation under ambient conditions has been

Rational Design of Ni3+‐Rich Nickel Nitride Enables Paired Electrooxidation of Sterol and Hydrogen Evolution in a Flow Electrolyzer

Advanced Science, EarlyView.
The rational design of Ni3+‐rich active sites on nickel nitride nanosheets via Pd‐induced electronic modulation, which was employed in the electrooxidation of sterol coupled with H2 production in a large flow electrolyzer. This work offers a novel strategy for the design and synthesis of highly efficient electrocatalysts and electrolyzers toward the ...

Steering the Shape‐shifting of Bullvalene‐PdII Complexes Through Steric and Geometric Strain

Angewandte Chemie, EarlyView.
This study explores the use of bis‐pyridyl substituted bullvalenes as dynamic shape‐shifting ligands within cis‐capped PdII complexes. The ring position of the pyridyl nitrogen is critical, leading to a range of Pd2L2 metallacycles and simple PdL complexes, each with distinctive bullvalene isomer preferences (represented in the figure by A‐D isomer ...

High chemoselectivity in the phenol synthesis

Beilstein Journal of Organic Chemistry, 2011
Efforts to trap early intermediates of the gold-catalyzed phenol synthesis failed. Neither inter- nor intramolecularly offered vinyl groups, ketones or alcohols were able to intercept the gold carbenoid species. This indicates that the competing steps of

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Domino Polymerization for the Synthesis of Reductively Degradable Poly(disulfide)s With Arbitrary Side‐Chain Structures

Angewandte Chemie, EarlyView.
We developed a novel domino polymerization to synthesize reductively degradable poly(disulfide)s with tunable side chains. A novel monomer bearing thiolactone and pyridyl disulfide groups reacts with various amines, enabling continuous ring‐opening and disulfide exchange.
