Summary: Anisotropic microparticles with various shapes were continuously prepared using a simple strategy that involved deforming oil-droplet templates within microfibers and locking their shapes via thermo/photo-polymerization. The size and geometry of the oil-droplet templates were precisely controlled by altering fluid flow conditions. Functionalized rod-like microparticles exhibited superior performance in removing contaminants compared to spherical microparticles, as they had a larger specific surface area for improved contact between catalysts and pollutants. Additionally, the magnetic rod-like microparticles could be easily recovered and reused without compromising their catalytic efficiency.

Summary: This study aimed to develop a multiphasic Janus particle system for programmed drug delivery. Triple-phase Janus microparticles with different degradation properties in each phase were generated using a one-step microfluidic preparation process. The particles exhibited programmed degradation behaviors and partial degradation as well as triggered cargo release in response to changes in temperature or pH. By modifying the particles with graphene nanosheets and silica nano-spheres, their functions were enriched. Co-loading of doxorubicin and curcumin in the triple-phase microparticles enabled zonal drug loading, and the particles showed programmed release behavior and enhanced tumor inhibition efficacy.

Summary: The exploration and synthesis of degradable plastics can help address environmental pollution caused by petroleum-based plastics. In this study, a KGM/zein/PVA ternary blend plastic was successfully prepared, and the addition of KGM and zein improved its compatibility and disrupted the molecular and crystalline structure of PVA. The blended plastic with the right proportion of KGM to zein exhibited the best mechanical properties and showed improved degradability compared to pure PVA plastic.

Summary: This study focused on controlling the particle sizes of polymer blends at low temperatures to ensure superior properties. The method employed exhibited energy efficiency during melt processing and resulted in a polymeric product with appreciable mechanical properties. By synthesizing a PS/PET blend system at 180 degrees C, the resulting blends showed uniquely shaped PET dispersed phase and mechanical properties that were significantly higher than blends processed at a higher temperature of 290 degrees C. The proposed method is the first to incorporate polymeric fibers into another polymer matrix at a lower temperature, leading to energy efficiency and superior mechanical properties.

Summary: Films of keratoses and sericin were successfully prepared using solution casting method with water as a common solvent and glycerol as a plasticizer. The addition of sericin led to rougher film surfaces, while there was good miscibility between keratoses and plasticizer. However, there were no covalent interactions between the polymers. Glycerol changed the thermal stability of sericin films, but had less impact on keratoses, and adding keratoses improved the mechanical properties of the sericin plasticized films.

Summary: Polymeric microparticles (MPs) have gained significant attention in environmental remediation due to their economic benefits, ease of manipulation, and ability to be recycled. However, most polymeric MPs contribute to microplastic pollution, which can be mitigated through the use of biodegradable polymers. In this study, we synthesized a photocurable polycaprolactone diacrylate (PCLDA) as a sustainable sorbent for treating organic contaminants. PCLDA formed a chemically interconnected network, allowing for a solid state with swelling behavior in organic solvents. Monodisperse oil-in-water emulsions were generated using a flow-focusing droplet generator and PCLDA solution, and MPs were formed through in situ photopolymerization under UV light. Compared to traditional solvent evaporation methods, PCLDA MPs exhibited a fine morphology and narrow size distribution. The swelling behavior of PCLDA MPs in different solvents was evaluated based on solubility parameter, and the particles demonstrated high performance as sustainable organic sorbents in the treatment of toluene oil droplets and solutes from water with good recyclability.
