Experimental Study on the Mechanism of Enhanced Imbibition with Different Types of Surfactants in Low-Permeability Glutenite Reservoirs.

Due to the complex physical properties of low-permeability glutenite reservoirs, the oil recovery rate with conventional development is low. Surfactants are effective additives for enhanced oil recovery (EOR) due to their good ability of wettability alteration and interfacial tension (IFT) reduction, but the reason why imbibition efficiencies vary with different types of surfactants and the mechanism of enhanced imbibition in the glutenite reservoirs is not clear. In this study, the imbibition efficiency and recovery of surfactants including the nonionic, anionic, and cationic surfactants as well as nanofluids were evaluated and compared with produced water (PW) using low-permeability glutenite core samples from the Lower Urho Formation in the Mahu oil field.

The Development of Prenatal Muscle Satellite Cells (MuSCs) and Their Epigenetic Modifications During Skeletal Muscle Development in Yak Fetus.

To investigate prenatal muscle satellite cell (MuSC) development and the associated epigenetic modifications in yak. Here, we conducted morphological and protein co-localization analyses of fetal longissimus dorsi muscle at various developmental stages using histology and immunofluorescence staining methods. Our study observed that primary muscle fibers began forming at 40 days of gestation, fully developed by 11 weeks, and secondary muscle fibers were predominantly formed by around 105 days.

Mesoporous silica nanoparticles as sensitizers: A novel approach to enhancing shear wave elastography in liver stiffness measurement.

Purpose: The objective of this study is to elucidate the sensitizing effect of mesoporous silica nanoparticles (MSNs) on shear wave elastography (SWE) and to investigate the potential application of MSNs as a sensitizer to enhance the sensitivity of SWE in the diagnosis of metabolic-associated steatohepatitis (MASH).

Rapidly self-crosslinking sodium alginate hydrogel for infected wounds.

The risks associated with wound infections are significant, making a snug-fitting hydrogel dressing an optimal choice for wound management. For it, we employed the self-cross-linking method of oxidized sodium alginate (SCSA), incorporating clarithromycin (Cla) and basic fibroblast growth factor (bFGF) to formulate a rapidly forming, bacteriostatic, and wound-healing hydrogel (SCSA@C/b). Bacteriostatic and cytocompatibility assays demonstrated that SCSA@C/b exhibits exceptional antibacterial activity alongside strong biocompatibility.

Linear Enhanced 3D Nanofluid Force-Electric Conversion Device.

The inherent trade-off between permeability and selectivity has constrained further improvement of passive linear force-electric conversion performance in nanofluidic pressure sensors. To overcome this limitation, a 3D nanofluidic membrane with high mechanical strength utilizing aramid nanofibers/carbon nanofiber (ANF/CNF) dual crosslinking is developed. Due to the abundant surface functional groups of CNF and the high mechanical strength of ANF, this large-scale integrated 3D nanofluidic membrane exhibits advantages of high flux, high porosity, and short ion transport path, demonstrating superior force-electric response compared to conventional 1D and 2D configurations.
