Abstract: This study explores novel alginate–konjac glucomannan core–shell aerogel particles for drug delivery systems fabricated via air-assisted coaxial prilling. A systematic approach is needed for the optimization of this method due to the numerous processing variables involved. This study investigated the influence of six variables: alginate and konjac glucomannan concentrations, compressed airflow, liquid pump pressures, and nozzle configuration. A hybrid software using A[...]

A Deep Simulation Study of Hydraulic Fracture Cleanup in Heterogeneous Tight Gas Reservoirs
Published on 2025-07-09 by Hamid Reza Nasriani, Mahmoud Jamiolahmady @MDPI
Abstract: Ultra-tight gas reservoirs present severe flow constraints due to complex interactions between rock–fluid properties and hydraulic fracturing. This study investigates the impact of unconventional capillary pressure correlations and permeability jail effects on post-fracture cleanup in multiple-fractured horizontal wells (MFHWs) using high-resolution numerical simulations. A novel modelling approach is applied to represent both weak and strong permeability jail phenomena in heteroge[...]
Our summary: A study on hydraulic fracture cleanup in tight gas reservoirs using high-resolution numerical simulations investigates the impact of unconventional capillary pressure correlations and permeability jail effects. The study reveals that strong jail zones hinder fracture fluid recovery, while weak jail configurations interact with heterogeneity to produce non-linear cleanup trends. Integrating unconventional Kr and Pc behavior in hydraulic fracturing design is crucial for optimizing flowback and long-term gas recovery.

Bionic Bovine Achilles Tendon Collagen Composite Membrane Loaded with Anti-Inflammatory Kukoamine B Promotes Skin Wound Healing
Published on 2025-07-04 by Ruting Luo, Yujie Mu, Le Zhao, Jinglin Hua, Lixin Cao, Danting Chen, Kun Li, Zhenkai Jin, Yanchuan Guo, Bing Zhang, Min Wang @MDPI
Abstract: Skin is the first line of defence between the human body and the outside world, and it is constantly exposed to external injuries and wounds for a variety of reasons. Collagen is a structural protein of the extracellular matrix and an important component of the dermis. As a wound dressing, collagen not only provides nutrients to wounds but also enhances the immune response in the pre-healing phase, making it an excellent biomaterial for healing. In this study, we used electrospinning and freeze-[...]
Our summary: Bovine Achilles Tendon Collagen Composite Membrane loaded with Anti-Inflammatory Kukoamine B promotes skin wound healing through enhanced immune response and nutrient delivery, making it an excellent biomaterial for healing. The physicochemical properties and biocompatibility of the membrane were verified, showing significant effects on skin wound healing in a mouse model. The composite membrane had the best capacity for promoting wound healing and can be used as a wound dressing for further research and development.

Abstract: This study aimed to evaluate the drying kinetics, microstructural features, moisture content, color, pH, aw, texture, acidity, rehydration capacity, and sensorial attributes of strawberry slices processed by different drying methodologies. Strawberry samples were processed by hot air-drying (HA, 60 °C, 0.5 m/s), freeze-drying (FD, 0.055 mbar), and pulsed electric field (PEF)-assisted freeze-drying (PEFFD, 1 kV/cm and 3.2 kJ/kg). PEF pre-treatment significantly increased cell membrane[...]
Our summary: This study evaluated the impact of different dehydration methods on the drying efficiency, nutritional and physico-chemical quality of strawberry slices. PEF pre-treatment improved drying efficiency and quality, with PEFFD samples showing better retention of shape and volume. Further research is needed to assess industrial scalability and economic feasibility.
