From Top to Bottom: Manufacturing Process‐Context Aware Resolution of Energy Device Electrodes Through a 3D Diffusion Generative Model

Advanced Energy Materials, EarlyView.
The application of a generative diffusion model, enhanced with a training data augmentation pipeline retaining the manufacturing process context of electrode microstructures, leads to improved fidelity of the through‐plane tortuosity factor in the AI generated samples.

Nanocrystalline LCO/LLZO Composite Cathode Films for Solid State Batteries

Advanced Energy Materials, EarlyView.
A single precursor solution is solution‐deposited and calcined at only 750°C to yield a dense, nanograined LiCoO2/LLZO composite cathode, in which both phases crystallize independently with minimal interdiffusion. Assembled into all‐solid‐state Li‐metal batteries, the composite delivers 111.7 mAh g−1 initial discharge capacity and retains 93% after 100

Hybrid DeepONet surrogates for multiphase flow in porous media

Journal of Computational Physics
The solution of partial differential equations (PDEs) plays a central role in numerous applications in science and engineering, particularly those involving multiphase flow in porous media. Complex, nonlinear systems govern these problems and are notoriously computationally intensive, especially in real-world applications and reservoirs.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Erosion and multiphase flow in porous media. Application to sand production

European Journal of Environmental and Civil engineering, 2010
ABSTRACT Experimental results from sand production hollow cylinders tests are presented for cavity failure and sand production quantification. The effects of important parameters such as the sandstone class, stress rate, fluid flow rate, and time are presented and show how they influence sand production.

Multiphase flow in fractured porous media [PDF]

, 1995
The major goal of this research project was to improve the understanding of the gas-oil two-phase flow in fractured porous media. In addition, miscible displacement was studied to evaluate its promise for enhanced recovery.

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

The competition between gravity and flow focusing in two-layered porous media [PDF]

, 2013
The gravitationally driven flow of a dense fluid within a two-layered porous media is examined experimentally and theoretically. We find that in systems with two horizontal layers of differing permeability a competition between gravity driven flow and ...

Transient multiphase multi-component flow in porous media

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1973
Abstract A one-dimensional transient two-phase, two-component flow in a porous medium is investigated analytically. The flow is described by the use of a continuity equation for each component, a momentum equation for each phase, the first law of thermodynamics, state equations, and relations for the transport properties.

From Ecological States to Trajectories: Revealing Ecological Dynamics Through Environmental Nucleic Acids

Biological Diversity, EarlyView.
Environmental nucleic acids (eNA) observations integrate temporal and ecological information across multiple dimensions of an ecological state. Repeated and complementary observations extend biomonitoring from state assessment toward reconstruction of ecological trajectories, including their direction, rate, pathways, progression, recovery, and ...
