Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations

open access: yesAnnalen der Physik, EarlyView.
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Chemical Bonds Containing Hydrogen: Choices for Hydrogen Carriers and Catalysts

open access: yesAngewandte Chemie, EarlyView.
Hydrogen carriers utilizing B─H, C─H, N─H, and O─H bonds are evaluated for their potential in hydrogen storage and release. Key candidates such as methanol, ammonia, and formic acid are examined with a focus on critical factors influencing performance, including the nature of chemical bonds, reaction pathways, and catalytic processes.

“Naked Nickel”‐Catalyzed Heteroaryl–Heteroaryl Suzuki–Miyaura Coupling

open access: yesAngewandte Chemie, EarlyView.
We report that an air‐stable “naked nickel”, Ni(4‐CF3stb)3, can efficiently catalyze heteroaryl–heteroaryl Suzuki–Miyaura cross‐coupling (SMC) reactions in the absence of exogenous ligands. This protocol permits the construction of >15 different heterobiaryls containing multiple Lewis basic heteroatoms from a broad set of 6‐membered heteroaryl bromides

In Situ High Selectivity Contact‐Electroreduction of CO2 to Methanol Using an Imine‐Mediated Metal‐Free Vitrimer Catalyst

open access: yesAngewandte Chemie, EarlyView.
A vitrimer catalyst with C═N bond enables efficient CO2 reduction via contact‐electrocatalysis, driven by water droplet‐induced charges. Imine groups stabilize CO2 adsorption, enrich electrons, and mediate electron transfer, achieving >90% methanol selectivity.

Advances and Challenges in Low‐Temperature Upcycling of Waste Polyolefins via Tandem Catalysis

open access: yesAngewandte Chemie, EarlyView.
This review presents an overview of recent advances in mild catalytic transformations of polyolefins, emphasizing the kinetic and thermodynamic interplay between endothermic C─C bond cleavages and the exothermic formation of new C─H, C─C, and C─O bonds.
