A New Metal‐Ester Bonding Motif for the Synthesis of Hybrid Molecular Catalysts on Metal Oxide Supports Leads to Tunable Reactivity

Angewandte Chemie, EarlyView.
This work reports a new metal–ester bonding strategy for anchoring molecular catalysts to metal oxide supports, achieving exceptionally high surface loadings. Catalyst reactivity is predictably tuned by the support's properties, enabling control over electronic behavior and reaction pathways, thus opening new possibilities for designing highly ...

Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

Advanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in

Synthesis of Cyclopropene‐Modified Fatty Acids Allows Single‐Cell Quantification of Uptake by Immune Cells

Angewandte Chemie, EarlyView.
Cyclopropene fatty acids have been made that allow the study of fatty acid uptake in complex mixtures of immune cells with single cell resolution and combined with metabolic and proteomic analysis so that for the first time nutrient uptake can be correlated to the phenotype of single immune cell.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

Angewandte Chemie, EarlyView.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

Angewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for
