3D Printed Sodiophilic Reduced Graphene Oxide/Diamane Microlattice Aerogel for Enhanced Sodium Metal Battery Anodes

Advanced Science, Volume 12, Issue 22, June 12, 2025.
A 3D printed sodiophilic rGO/diamane microlattice aerogel with uniform ions flux and exceptional sodiophilic features is demonstrated as a stable host for sodium metal anode. The sodiophilic diamane nanoflakes regulate the uniform deposition of metallic Na with a dendrite‐free deposition morphology, achieving an ultra‐high areal capacity of 78.60 mAh ...

Effects of pressure depletion rate, solvent, and surfactant on non‐equilibrium reactions in foamy oil

The Canadian Journal of Chemical Engineering, Volume 103, Issue 6, Page 2688-2707, June 2025.
Overview of the Investigation into the Effective Operating Parameters of the Foamy Oil Process. Abstract This research employed a visual method to explore the behaviour of foamy oil in heavy oil systems. A Hele‐Shaw cell was designed for observing the volumetric expansion of foamy oil as the system pressure decreased.

Impact of Heterogeneity and Miscibility on scCO2 Drainage Flow Patterns and Implications for Experimental Interpretation

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract In this study, we investigated the coupling effect of sub‐core‐scale heterogeneity and miscibility on the development of flow pattern under drainage in porous media. We performed experiments with two Bentheimer sandstone cores (usually considered homogeneous) both with mild heterogeneity. For both cores, two drainage experiments were performed:

Experimental and modelling studies on static sag of solid weighting powders in Polysulfonate workover fluids at high temperature and high pressure

Petroleum
The solid weighting material in a high-density workover fluid is prone to static sag. Existing experimental methods cannot predict the parameters of the settling stability of workover fluids at high temperature and high pressure (HTHP).

Numerical Modeling and Simulation of Thermal Effect-Driven Bottom Hole Pressure Variation and Control Technology During Tripping-Out in HTHP Ultra-Deep Wells

Modelling
Controlling bottom hole pressure (BHP) during tripping-out is a key challenge in ultra-deep well drilling. Under high-temperature and high-pressure (HTHP) conditions, ultra-deep wells feature long tripping-out cycles, where thermal effects are prone to ...
