Characterization of the acoustic cavitation in ionic liquids in a horn-type ultrasound reactor

Ultrasonics Sonochemistry
Most ultrasound-based processes root in empirical approaches. Because nearly all advances have been conducted in aqueous systems, there exists a paucity of information on sonoprocessing in other solvents, particularly ionic liquids (ILs).

Strongly‐Anchored Ionomer‐Free Anode Catalyst Layer Fabricated via Joule Heating Achieves Efficient Electron/Mass Transfer for Acidic Water Electrolysis

Carbon Energy, EarlyView.
An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.

Influence of Contact Pressure on Performance and Crossover in Zero‐Gap Alkaline Water Electrolysis

Chemie Ingenieur Technik, EarlyView.
Cell performance and product gas quality in zero‐gap alkaline water electrolysis are influenced by the mechanical contact pressure in the electrode area. With a newly developed contact‐pressure cell, it was found that the influence of contact pressure can vary drastically, depending on the cell configuration, electrode type, and diaphragm.

Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...
