Summary: Tissue engineering scaffolds with tunable viscoelasticity and adaptability were fabricated using a dynamic interpenetrating polymer network (IPN) hydrogel. The IPN hydrogel consisted of methacryloyl gelatin (GelMA) and hyaluronic acid (HASH), with GelMA providing stable support for cells and HASH providing an adaptable microenvironment for cell growth. The IPN hydrogel exhibited tunable porosity, swelling, degradation, and mechanical properties, mimicking the extracellular matrix (ECM) and regulating cellular behaviors. The hydrogel showed promise in promoting the growth of human skin cells and in the development of bilayer tissue-engineered skin with satisfactory mechanical stability and barrier functions, leading to accelerated wound healing.

Summary: This study developed a novel conductive self-healing hydrogel through an interpenetrating polymer network strategy, showing reversible self-healing in both mechanical and electrical properties. The self-healing mechanism was determined using H-1 NMR and FT-IR spectroscopy, demonstrating the cooperative effect of dynamic covalent and noncovalent interactions for its self-healing capability. The hydrogel's macroscopic and microscopic properties were examined through rheology, scanning electron microscopy, and light-emitting diode circuits, showing potential for applications in soft and conformable electronics.

Summary: This work explores the preparation of ionic liquid (IL)-based semi-interpenetrating polymer network (sIPN) membranes composed of poly(ethylene oxide) (PEO) network and linear nitrile butadiene rubber (NBR). The incorporation of different ILs improved the thermal stability of the membranes and affected mechanical properties while maintaining high elongation properties, ultimately enhancing CO2/N-2 and CO2/H-2 separation performances.

Summary: In this study, IPN hydrogels with high flexibility and conductivity were prepared by modifying agar, oxidized alginate, and polyacrylamide. The presence of potassium and sodium ions in the modified agar and alginate chains endowed the hydrogels with conductive properties. These hydrogels exhibited strain-sensitive properties and can be used for detecting human motion. Furthermore, they maintained their flexibility and conductivity even after storing for six months.

Summary: Flexible zinc-air batteries with gel polymer electrolyte (GPE) are considered promising for next-generation wearable devices due to their high energy density, low cost, safety, and environmental friendliness. However, the evaporation of liquid component in GPE significantly reduces battery performance and lifespan. To address this issue, a hierarchically porous PVA/PAA hybrid GPE is developed, which improves electrolyte uptake and retention properties, and enhances ionic conductivity. The hybrid GPE demonstrated excellent cycling stability, rate characteristics, and power output in zinc-air batteries, showing their feasibility for powering wearable smart watches.

Summary: The CLCsolid balls exhibit excellent elastic properties suitable for small strain sensors, while the CLCsolid-IPN balls show pH-responsive color change, which can be applied for small pH sensors. Immobilizing urease on the CLCsolid-IPN balls enables their use as small urea sensors. The CLCsolid-IPN-KOH balls, when swollen, can be used to detect divalent metal ions, making these photonic balls a potential new sensor platform with simple functionalization and minimal sample requirements.

Summary: This study demonstrates underwater self-layering interpenetrating polymer-network coatings with excellent anti-fouling and anti-icing properties. The coatings, consisting of fluorocarbon resin and poly-acrylate, exhibit micro-wrinkled structures on the surface, which reduce surface energy and prolong ice-crystal nucleation time. The coatings show exceptional adhesion inhibition against bacteria, algae, and mussels as well as excellent de-icing and anti-icing performance after immersion.

Summary: Solid-state lithium metal batteries (SSLMBs) are an ideal future energy source due to their enhanced safety and energy density. Poly(ethylene oxide) (PEO)-based network solid polymer electrolytes (SPEs) have attracted attention for their low cost and good device performance. However, they face an issue of low anodic stability. Through the introduction of an interpenetrating network (IPN) consisting of PEO-based SPE and PAN secondary network, the oxidative stability was significantly increased, allowing SSLMBs to achieve high capacity and excellent cycling stability.

Summary: To enable large-scale commercial applications of anion exchange membrane fuel cells, it is crucial to achieve high ionic conductivity and long-term durability of anion exchange membranes (AEMs). In this study, a novel tripartite cationic full-interpenetrating polymer network (F-IPN QPSVBC-PQ10) AEM was fabricated using poly(styrene-co-4-vinylbenzyl chloride) (PSVBC) as the framework material and secondary anion carrier, and polyquaternium-10 (PQ10) as the main anion carrier. The optimized AEM exhibited excellent mechanical properties, dimensional stability, alkaline stability, and oxidation resistance, with an ionic conductivity of 81.89 mS/cm and a peak power density of 119.31 mW/cm2. Moreover, it maintained 91.06% of its initial mass and 88.37% of its original ionic conductivity after successive oxidation and alkali resistance tests. This unique design of tripartite cationic F-IPN AEMs without aryl ether linkages holds great promise for the development of high-performance anion exchange membranes.

Summary: This study demonstrates that CRH induces complex intrafollicular HPA response and non-HPA-related stress response in human AGA HFs, which can be effectively antagonized by caffeine. Additionally, caffeine enhances the expression of inositol trisphosphate receptor, newly detected in human HFs, supporting the hypothesis that stress can impair human hair physiology and induce hair loss, and caffeine may prevent stress-induced hair damage and loss.
