Summary: A composite ER polishing particles composed of PIL ER active particles covalently attached with commercial Al2O3 nanoabrasives is reported, offering a solution to the insufficient performance of traditional ER polishing fluids. The composite particles, prepared by polymerization of a Pickering emulsion, effectively overcome the phase separation issue and exhibit significantly better ER effect and polishing property compared to simple mixtures. By integrating ER effect and polishing property into a particle system, this study provides a new direction for improving ER polishing technology.

Summary: In this study, a direct approach for the fabrication of noncovalent raspberry-shaped microgels was developed. This approach utilizes electrostatically driven heterocoagulation of binary microgels with complementary functional groups at the oil-water interface. The results show that the addition of hexanoic acid improves the hydrophobicity and interfacial activity of microgels, and raspberry-shaped microgels achieve high coverage on the droplet surface, resulting in an elastic interface and excellent stability of emulsions.

Summary: This study investigates the polymerization kinetics with different thermal initiators in various LLC structures, finding that the IFW system utilizing ammonium persulfate exhibits higher reaction rates and conversion rates compared to the IFO system using azobisisobutyronitrile and benzoyl peroxide. It is also discovered that nanoconfinement effects on polymerization rates can be minimized through the IFW system, as shown in both DSC and chemorheology results. Additionally, polymers obtained from the IFW system show improved mechanical properties compared to those from the IFO system at similar monomer conversions.

Summary: Precise multiblock copolymer synthesis coupled with self-assembly provides control over the structure on length scales from nanometers to micrometers. The use of a nanoreactor concept in emulsion polymerization has expanded the scope of multiblock copolymer synthesis. However, the high glass transition temperature of some polymers has been a limitation. This study demonstrates that this limitation can be alleviated by choosing the appropriate radical initiator. More hydrophobic initiators resulted in narrower molecular weight distributions. These findings are expected to significantly expand the range of low-dispersity multiblock copolymers in aqueous emulsion via RAFT polymerization.

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.
