Summary: We successfully prepared mesoporous polymer microspheres with uniform pore size using aqueous suspension polymerization. The size and pore size of the microspheres can be independently controlled, and they exhibit a nanostructured bicontinuous morphology. We also demonstrated the incorporation of functional pore walls and showed the high efficiency of the microspheres in dye removal. This method has great potential for applications in catalysis, chromatography, and water remediation.

Summary: The suspension polymerization process was used to create acrylate resin microspheres for mesh coating technology. The synthesized microspheres had mesh numbers of 140-200 µm and particle sizes of 100 µm. The optimal reaction conditions for synthesis were determined to be a dispersant dosage of 30 g of calcium carbonate, a monomer ratio of 4:1, a reaction time of 1 h, an initiator dosage of 1.2 g of BPO, and a reaction temperature of approximately 75-80 °C, resulting in microspheres with a regular spherical shape and smooth surface.

Summary: A new method of water-compatible noncovalent imprinted microspheres was proposed to overcome the challenges in preparing molecularly imprinted polymers (MIPs) with specific recognition in aqueous solution. The method involved screening functional monomers using molecular dynamics (MD) and preparing spherical MIPs with a modified suspension polymerization method. The synthesized SPM-MIP and CDCA-MIP showed high adsorption capacities, selectivity, and resistance to protein adsorption in an aqueous medium.

Summary: This study introduces a method for synthesizing microspheres using sunlight as a purely light-driven platform, producing stable particles without the need for initiators, surfactants, or heating. This unconventional approach provides a new opportunity for particle synthesis, different from the traditional thermally-driven methods.

Summary: A new type of ultra-lightweight proppant with high compressive strength was prepared via in situ suspension polymerization, showing good sphericity and even dispersion of fly ash in the matrix. The obtained poly(St-co-MMA)/FA composite microspheres are promising for application as an ultra-lightweight proppant in oil or gas exploitation, providing a new approach for the design of high performance proppants.

Summary: Polystyrene microspheres were prepared in magnetized form using a modified route of suspension polymerization with a surface-active agent as stabilizer, ensuring uniform size and stable magnetic property. The addition of oleophilized iron oxide nanoparticles in the monomer phase played a key role in achieving the successful production of microspheres with excellent and stable ferromagnetism.

Summary: In this study, fluorine-free superhydrophobic separation films were prepared by depositing polymer microspheres on stainless steel meshes. The hydrophobic meshes showed excellent oil-water separation efficiency and permeation flux, and remained stable in corrosive environments. These meshes have potential practical applications in sewage treatment or separation/purification.

Summary: In this study, PSm materials were successfully synthesized via suspension polymerization method with a particle size distribution ranged around 90-200 μm. The repeatability of PSm synthesis and its radioactivity measurement performance were verified. Optimal concentrations of fluorescent materials were determined to achieve good light yield and counting efficiency. The counting efficiency of PSm was significantly affected by the quenching of the solution.

Summary: Oil absorbent particles made from surface-modified polypropylene can facilitate the removal of oil from the environment. In this study, it was found that these particles stimulated the growth of biofilms and enriched specific bacterial species. Compared to oil suspension, cultures with these particles degraded more crude oil. Bacterial communities pre-exposed to crude oil had different community structures and degraded more oil.

Summary: The study evaluated the toxicity of four widely used essential oil components on nematodes and found that these compounds had a concentration-dependent effect on nematode survival at moderate to high concentrations, with reproduction being a more sensitive endpoint for toxicity evaluation. The findings suggest that these compounds can be toxic at lower doses than those required for their biological action.
