Experimental study on channeling plugging with in-situ generating foam in CO2 displacement process

Youqi dizhi yu caishoulu
In order to solve the problem of channeling in the process of CO2 displacement， a technique of the in-situ generating foam system carried by CO2 for formation flow and foam plugging was studied. The law of channeling plugging with in-situ generating foam

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Hydrogels Augmented With Artificial Sweeteners can Inhibit Multidrug‐Resistant Acinetobacter baumannii Growth and Biofilm Formation While Demonstrating Safety in Pre‐Clinical Pilot Human Trials

Advanced Healthcare Materials, EarlyView.
Using PVA–borax hydrogels as carriers for off‐the‐shelf artificial sweeteners to fight multidrug‐resistant A. baumannii. These soft, biocompatible hydrogels rapidly reduce bacterial viability within multidrug‐resistant A. baumannii biofilms by more than 99% within one hour and sustain antimicrobial activity over time, while demonstrating safety in both

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.

Effect of temperature and surfactant concentration on CO2 foam strength in Bentheimer sandstone at reservoir conditions

Journal of Petroleum Exploration and Production Technology
Surfactant-stabilized CO2 foams reduce CO2 mobility and improve CO2 sweep efficiency during CO2 enhanced oil recovery (EOR) and storage processes. However, the behavior of nonionic surfactant-stabilized CO2 foams near their cloud-point regions remain ...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Assessment of foam generation and stabilization in the presence of crude oil using a microfluidics system

Journal of Petroleum Exploration and Production Technology, 2023
The use of foams is a promising technique to overcome gas mobility challenges in petroleum reservoirs. Foam reduces the gas mobility by increasing the gas apparent viscosity and reducing its relative permeability.

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.
