Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Chiral‐at‐Metal Racemization of Tris‐Chelated Octahedral Complexes: A DFT Case Study of Al(acnac)3

Chemistry – A European Journal, EarlyView.
Racemization and isomerization of M(a‐chel)3 complexes was unraveled using Al(acnac)3 as a model. The ∆/Λ‐fac isomers have four racemization paths of which one includes isomerization to and racemization of the mer isomer. N‐substitution should enable separation of the ∆‐fac and Λ‐fac enantiomers.

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.
