Summary: In this study, hierarchical porous hydroxyl aluminum oxide hollow microspheres with controllable structure and morphology were prepared. The CO2 trapping performance of potassium carbonate-based adsorbents prepared using these microspheres as supports was evaluated. The results showed that the loading of potassium carbonate, the pore structure, and the surface basic site of the adsorbent significantly influenced its CO2 trapping performance.

Summary: A novel, facile and continuous flow photopolymerization of Pickering emulsion method was used to fabricate nanoporous composite microspheres. Palygorskite (PAL) fibers were chosen as stabilizers in the oil phase system, which included Methyl methacrylate (MMA), (ethylene glycol) diacrylate (EGDMA), Irgacure 819 (I 819, photoinitiator), and toluene (porogenic agent). The influence of PAL concentration on the emulsion stability and the morphology of the microspheres was fully investigated. It was found that the presence of 1.5 wt% PAL fibers provided the best conditions for obtaining polymerized porous microspheres. N-2 adsorption-desorption isotherm characterization revealed a specific BET surface area of 171 m(2)/g, indicating the great potential applications of this methodology. Suitable polymerization flow rate was also found to be a key parameter for the formation of PMMA/PAL composite microspheres. The formation mechanism and porosity of the microspheres were discussed.

Summary: Two methods were developed to fabricate porous poly(L-lactide) (PLLA) fibres with good internal pore connection, including the removal of a pore-forming agent and non-solvent induced recrystallization. The results showed that the porous structures were successfully achieved in PLLA fibres with higher crystallization, leading to improved mechanical properties.

Summary: In this study, porous polymeric microspheres were prepared using a one-pot strategy involving photopolymerization and organic solvents as porogens. The oil phase, containing organic solvents and photopolymerizable materials, was stabilized in water to form a stable emulsion. Upon UV irradiation, the photopolymerizable materials underwent polymerization to form microspheres, and the subsequent removal of organic solvents resulted in the generation of porous polymeric microspheres. The effects of organic solvents, as well as the chemical structure and concentration of photopolymerizable materials, on the microsphere structure were systematically explored. This strategy allows for the scalable and facile preparation of porous microspheres in a time-saving and energy-saving manner.

Summary: In this study, a new microfluidic device was proposed for generating double-emulsion droplets without pre-emulsification. The device allowed for easy control of particle size and porosity by adjusting flow rates. The characteristics of the PLGA microspheres, including SEM images, drug loading capacity, and encapsulation efficiency, were analyzed, with porosity being a key factor. This study provides a continuous and efficient method for preparing double-emulsion droplets or structured/functio000ning polymetric microspheres, applicable to various industries.

Summary: In this work, carboxylated azobenzene-coordinated metal-organic-framework (AZO-MOF) ion channels with impressive light-gating properties were synthesized, achieving high on-off ratios up to 40.2. The AZO-MOF ion channels maintained a crystalline and three-dimensional porous structure, and the AZO-containing ligands controlled the pathways by bending and stretching upon light irradiation. This study suggests a way to achieve subnanoscaled gating of ion transport by angstrom-porous MOFs coordinated by stimuli-responsive ligands.
