Topology‐Dependent Coke Formation in the Catalytic Pyrolysis of Phenol Over HFAU and HZSM‐5 Zeolites

Angewandte Chemie, EarlyView.
The coke formation and speciation during the catalytic pyrolysis of lignin over different zeolite topologies were studied with a combination of operando EPR spectroscopy and ex situ pulsed techniques aided with DFT calculations. Operando EPR data showed that the coke formation in HFAU is fast compared to HZSM‐5.

Ultra‐Low‐Strain Calcium and Magnesium Ion Storage Enabled by Tunnel‐Structured MoO3 Positive Electrode

Advanced Energy Materials, EarlyView.
A hexagonal tunnel‐structured MoO3 is nanoparticulated via hydrothermal synthesis followed by ball‐milling. As a positive electrode in Ca and Mg batteries, it delivers superior capacity and structural reversibility, enabling divalent cation intercalation with minimal lattice distortion and no phase transitions.

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.

Alkyne‐Based Dual‐Function Self‐Assembled Monolayers for Efficient and Stable p‐i‐n Perovskite Solar Cells

Angewandte Chemie, EarlyView.
A novel molecular design strategy is employed to modify the D–A type SAM using an alkyne linker. Incorporation of the alkyne linker enhanced π‐electron delocalization, facilitating more efficient hole transfer, and strengthened interfacial bonding, thereby improving device stability. As a result, the perovskite solar cells achieved an impressive PCE of

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

Angewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Radical‐Based On‐Surface Transformation of Nonplanar Aromatics Into Nonbenzenoid Nanographenes

Angewandte Chemie, EarlyView.
Formation of radicals in nonplanar hydrocarbons through thermally induced dehydrogenation leads to molecular transformation via intramolecular radical‐based cyclization and dimerization, leading to formation of nonbenzenoid nanographenes. ABSTRACT On‐surface synthesis has emerged as a powerful tool for atomically precise C─C bond formation, enabling ...

Nickel‐Catalyzed Enantioconvergent Arylation of Unactivated Cyclic Electrophiles: Asymmetric Synthesis of 3‐Substituted Pyrrolidines

Angewandte Chemie, EarlyView.
Metal‐catalyzed enantioconvergent substitutions of unactivated cyclic electrophiles by organometallic nucleophiles have not previously been reported. Herein, a chiral nickel catalyst is described that achieves this objective, coupling 3‐iodopyrrolidine derivatives with arylzinc nucleophiles.
