Summary: This study introduces the use of Millettia speciosa Champ cellulose (MSCC) and carboxymethylcellulose (MSCCMC) in the fabrication of 3D-network hydrogels as a delivery system for probiotics. The structural features, swelling behavior, and pH-responsiveness of the MSCC-MSCCMC hydrogels were characterized, along with their encapsulation and controlled-release behavior for Lactobacillus paracasei BY2 (L. paracasei BY2). The results showed that the MSCC-MSCCMC hydrogels had porous and network structures, and their properties were influenced by the concentration of MSCCMC.

Summary: Traditional biopolymer coating technologies such as spray-drying and freeze-drying have difficulties with bioactive-loaded vesicular systems. Electrohydrodynamic processing, including electrospinning (ES), is an emerging new technology for addressing these challenges. This review summarizes the principles of ES and explores the application of plant proteins as electrospun fibers (EFs) in meat analogues. It also discusses the encapsulation of various bioactives through ES techniques using meat analogue proteins, with a focus on vesicular systems. The study examines the potential of vesicular embedded EFs in antioxidant and antimicrobial food packaging, as well as the enhancement of bioaccessibility and protection of loaded bioactives.

Summary: We developed a switchable hydrogel film adhesive with pattern-tunable wrinkles to control adhesion, addressing the challenges of on-demand adherence and detachment from tissue surfaces. The generated compressive stress from the bilayer system leads to self-similar wrinkling patterns at different wavelengths, regulating interfacial adhesion. We demonstrated the application of our adhesive in a random skin flap model, showing its potential for tissue sealing, neovascularization promotion, and gradual detachment through dynamic wrinkling pattern transition.

Summary: In this study, protein-reinforced pectin hydrogel beads were developed to overcome the limitations of porous networks and poor mechanical properties. HBPEC-CAS showed a compact network structure and high encapsulation efficiency of EGC, with the ability to delay its release in an aqueous environment and ensure sufficient release in a simulated gastrointestinal environment. Furthermore, EGC was chemically stabilized in HBPEC-CAS through the inhibition of its epimerization, oxidation, dimerization, and trimerization. These findings offer valuable insights for the tea-based food and beverage industry.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
