Summary: Green polymers, such as Chitosan, were synthesized in this study for environmental applications. The swelling behavior of crosslinked and physical Chitosan hydrogels were compared, showing that crosslinked hydrogels have better mechanical strength but lower water absorption compared to physical hydrogels. The research also found that swelling of the hydrogels increased with temperature and lower salt concentrations.

Summary: Recent research has focused on the development of drug-loaded hydrogels for wound healing. A carboxymethyl chitosan-gelatin hydrogel was chemically cross-linked using genipin as the cross-linking agent to deliver both substance P and DMOG. The synthesized hydrogels showed good biocompatibility and physicochemical properties, with the SP and DMOG combination promoting cell proliferation and facilitating wound healing in vivo. These findings suggest the potential application of this co-loaded drug hydrogel as a wound dressing material.

Summary: A cactus mucilage-gelatin bio-composite film was made using a solution casting method. The effects of citric acid as a crosslinking agent at different concentrations on the film's moisture sorption characteristics and mechanical properties were studied. Results showed that incorporating citric acid reduced the film's moisture content, swelling ratio, water vapor permeability, and moisture sorption tendency. The film with 0.5% citric acid exhibited the best crystallinity and highest tensile strength, making it suitable for food packaging applications.

Summary: A pH-sensitive composite hyaluronic acid/gelatin hydrogel drug delivery system containing carboxymethyl chitosan microspheres loaded with CUR was fabricated for the treatment of IBD. In vitro studies showed good sustained release properties, with a drug release rate of 65% over 50 hours. In vivo pharmacokinetic experiments demonstrated that high levels of CUR were maintained in colon tissue for over 24 hours, exhibiting anti-inflammatory effects and inhibiting pro-inflammatory cytokines secretion. The formulation group of CUR@gels showed the best therapeutic effect on colitis in mice, indicating the potential of the composite gel delivery system for effective CUR delivery in colitis treatment.

Summary: It was found that the use of nano-platelet aluminum particles in PET materials not only increased the tensile modulus, tensile strength, and impact resistance, but also significantly improved the flexural modulus. The aluminum platelets could easily become oriented during molding, leading to higher performance compared to talc, mica, and graphene. The aluminum-polyethylene terephthalate (Al-PET) composite is a cost-effective and high-performance combination for making conductive composites.

Summary: Conductive plastics, created by adding conductive fillers to polymer matrices, are more effective when used in binary polymer blends with a co-continuous morphology. Embedding aluminium nano platelets, a relatively low-cost conductive filler, in a 60/40 PBT/PET polymer blend resulted in a reduction of resistivity to the level of an electrostatic charge dissipation material. The dimensional stability of the conductive articles remained above the T-g of PET due to the crystallization of the 60/40 PBT/PET blend during injection molding.

Summary: In this study, polypropylene composites with strontium aluminate-based fillers were prepared and their auto-glowing properties were examined. The intensity of the phosphorescence emission and decay was found to be proportional to the filler content. The fillers decreased the overall crystallinity of the composites without affecting the melting and crystallization temperature values. The thermal stability of the composites was slightly improved with the fillers, but the mechanical properties were decreased.

Summary: In previous works, the addition of micron-sized, irregular-shaped aluminum powder or aluminum nano platelets improved the mechanical properties and electrical conductivity of polyesters. However, when using nano-spherical particles of aluminum in a PBT/PET polyester blend, the tensile strength and flexural strength decreased gradually with increasing filler loading. The spherical shape and nano size of the Al particle caused it to be less effective than the micron-sized, irregular-shaped Al powder or flakes.

Summary: This study investigates the effects of incorporating stearic acid in candelilla wax and groundnut oil oleogel. The results show that stearic acid modifies the crystal structure of the oleogel and increases ordering within the crystallite network. Interestingly, the firmness of the oleogel remains unaffected, but the spreadability decreases with the addition of stearic acid. The addition of stearic acid also affects the color and crystallization rate of the oleogel.

Summary: This research investigated the effects of stearic acid, sunflower lecithin, and sorbitan monooleate on SYW/RBO-based oleogels. The samples were analyzed using various techniques, including colorimetry, microscopy, FTIR, mechanical testing, crystallization kinetics, X-ray diffraction, and drug release investigation. The results showed that emulsifiers did not affect the appearance or oil binding capacity of the oleogels. Emulsifiers smoothed the surface and influenced the crystallization kinetics of the oleogels. The drug release study indicated that emulsifiers had a significant impact on the release of curcumin from the oleogels.
