Summary: In this work, stable limonene-in-water Pickering emulsions were successfully produced by synthesizing biodegradable nanoparticles through a combination of polymerization techniques. The size of the oil phase and wetting properties of limonene could be strictly controlled by tuning the physico-chemical properties of the nanoparticles. The adoption of thermo-responsive polymer chains within the emulsifiers allowed on-demand destabilization of the emulsions for selective dispensing of limonene by increasing the temperature.

Summary: The electrical connection between the redox active site of enzymes and the electrode surface is crucial for the performance of enzyme catalyzed biofuel cells. In this study, a polythiophene-titanium oxide (PTH-TiO2) nanocomposite was synthesized and used as a support material for immobilizing the mediator ferritin (Frt) and the enzyme glucose oxidase (GO(x)) to create a highly efficient and stable bioelectrode. The electrochemical analysis confirmed that the use of PTH-TiO2 significantly improved the bioelectrocatalysis of glucose to gluconolactone via GOx.

Summary: A new-fangled PSA@PS-TiO2 photocatalyst was fabricated using periwinkle shell ash (PSA) and polystyrene (PS). The morphological images of all samples showed a size distribution of 50-200 nm. The PSA@PS-TiO2 exhibited better photocatalytic efficiency for methyl orange degradation due to its rough surface morphology, main crystal phases of TiO2, low bandgap, and beneficial functional groups.

Summary: This study investigates the influence of initiator type on the morphology of PP/PS composite particles. It was found that cationic initiator VA-044 led to the formation of multilayer structures in the composite particles, while the nonionic initiator VA-086 resulted in void structures with a PP shell encapsulating the PS phase. Anionic initiator V-501 led to PS primarily attaching to the outer surfaces of PP particles. These differences were due to electrostatic interaction between the initiator and PP particles of negative zeta potential.

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.
