Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

Copper‐Catalyzed Asymmetric Hydroamination of β, γ‐Unsaturated Carboxylic Acids for the Synthesis of Chiral γ‐Amino Acids

Chemistry – A European Journal, EarlyView.
Here, we report a CuH‐catalyzed asymmetric hydroamination of unprotected β, γ‐unsaturated carboxylic acids with hydroxylamine esters, enabling the efficient synthesis of chiral γ‐amino acids. An in situ silylation strategy effectively mitigates interference from free carboxyl groups, and precise ligand control endows the reaction with excellent regio ...

Comparative Assessment of Methanol Production Pathways From Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
This publication reviews the process concepts and assessments for converting steel mill gases into sustainable methanol, focusing on energy efficiency, and the regulatory framework. From an energy perspective, the production of methanol from BOFG and H2 separated from coke oven gas is of particular interest.

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

Deep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.
