Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]

, 2009
In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...

Polypropylene foam behaviour under dynamic loadings: Strain rate, density and microstructure effects [PDF]

, 2009
Expanded polypropylene foams (EPP) can be used to absorb shock energy. The performance of these foams has to be studied as a function of several parameters such as density, microstructure and also the strain rate imposed during dynamic loading.

Numerical Simulation of Foam Flooding For Sweep Improvement [PDF]

Annual Technical Meeting, 1997
Abstract Foams are used for mobility control in Enhanced Oil Recovery operations involving injection of gases or steam. The ability of foams to lower the mobility of the vapor phase, under certain conditions, helps in reducing gravity override and channeling leading to improved sweep efficiency and oil recovery.

Characteristics of viscosity-reducer foam flooding in deep low-permeability heavy oil reservoirs

Youqi dizhi yu caishoulu
Viscosity-reducer foam flooding combines the advantages of emulsification of viscosity-reducers and selective blocking of foam to further enhance oil recovery in deep low-permeability heavy oil reservoirs during the later development stages. The suitable

Adaptability to Enhance Heavy Oil Recovery by Combination and Foam Systems with Fine-Emulsification Properties

Energies, 2023
Emulsification is increasingly emphasized for heavy oil recovery through chemical flooding. However, whether systems with fine-emulsification (FE) properties significantly outperform conventional ultra-low interfacial tension (IFT) systems, especially ...

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

Advanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.
