Summary: The relationship between interfacial and bulk emulsion viscoelasticity was investigated in water-in-dodecane reverse Pickering emulsions stabilized with partially hydrophobic silica particles. The results showed that silica and NaCl concentrations affect the viscoelastic properties of the emulsions, with a correlation between the elastic modulus and silica concentration. Increasing the NaCl concentration strengthened the viscoelastic properties of the emulsions, and both silica and NaCl had similar effects on the interface and bulk viscoelastic properties.

Summary: The main stabilization mechanism of Pickering emulsions stabilized by ethyl cellulose nanoparticles is the adsorption of particles at the interface, rather than the formation of a network in the continuous phase. The presence of particles at the interface causes short-range interactions between the droplets, as observed from the rheological behavior of the emulsions.

Summary: Pea protein isolate nanoparticles (PPINs) induced by potassium metabisulfite (K2S2O5) were found to stabilize oil-in-water high internal phase emulsions (HIPEs) by forming a thick interface film, leading to smaller droplet size and better storage and centrifugal stability. These HIPEs exhibited gel-like structure with a higher storage modulus than loss modulus, and remained stable despite flocculation under different conditions, suggesting PPINs-stabilized HIPEs as a potential alternative to hydrogenated oils to reduce trans fatty acid intake.

Summary: Acetylated Kraft lignins were used to structure vegetable oils into oleogels. Microwave-assisted acetylation at higher temperatures resulted in gel-like oil dispersions with improved viscoelastic properties and stronger shear-thinning character, along with enhanced long-term stability. The modified lignins enhanced the stability of water-in-oil Pickering emulsions by enhancing hydrogen bonding between the oil and nanoparticles.

Summary: A magnetic Pickering emulsion is a stable emulsion that can be controlled by an external magnetic field due to the accumulation of magnetic nanoparticles at the droplet interface. Research in this field focuses on the rheological properties and stability of the emulsion, comparing it with other magnetic fluids. The results show that the application of a magnetic field increases the rigidity and resistance to deformation of the emulsion.

Summary: The study shows that particles play a significant role in the rheological behavior of Pickering emulsions, supporting the existence of a three-dimensional network between droplets. The applied percolation method can quantitatively estimate a viscoelastic link between particles, which significantly affects the viscosity and elastic modulus of the emulsions, contrary to the traditional view of interfacial monolayers stabilizing Pickering emulsions.

Summary: This study developed pH-responsive Pickering emulsions stabilized by a low concentration of bare highly hydrophilic Ludox CL nanoparticles without surface modification or addition of surfactants. The formed protective armor and network-like aggregates can separate droplets from each other to prevent coalescence, leading to the formation of stable emulsions that can last up to half a year. Additionally, the method of preparing organic-inorganic composite particles using the template action of the Pickering emulsions provides a simple green strategy for the preparation of stable emulsions.

Summary: This study aimed to improve the surface hydrophobicity and adsorption properties of Zein nanoparticles (ZN) by using the hydrophobic substance Medium-chain triglyceride (MCT) to form hybrid nanoparticles (ZMN). The results showed that the surface hydrophobicity of nanoparticles affected their adsorption properties and the rheological behavior of the composite interface. The increase in the Zein/MCT ratio promoted the exposure of hydrophobic groups and led to rapid adsorption and densely accumulation of ZMN at the interface.

Summary: In this study, water-in-oil (W/O) Pickering emulsions stabilized by different interfacial nanoparticles (ethyl cellulose-EC, whey protein isolate-WPI, Zein) and oleogel networks (glycerin monostearate) were investigated. The study explored the influence of different nanoparticles and oleogel networks on the properties of emulsions under varying internal phase fractions. The findings revealed a dual stabilization mechanism for W/O emulsions, with both nanoparticles and oleogel networks contributing to emulsion stability.

Summary: The role of egg yolk low density lipoprotein (LDL) as a stabilizer in high internal phase Pickering emulsions (HIPEs) was comprehensively studied. The optimal formulation of HIPEs was found to be 80% oil phase and 2% LDL concentration, which resulted in small and uniform droplets. After freeze-thawing cycles, the gel structure of HIPEs was restored through simple rehomogenization. Encapsulation of curcumin into Pickering HIPEs improved its photostability and bioaccessibility.

Summary: Pickering bitumen emulsions stabilized by 1 % aqueous dispersion of microfibrillated cellulose (MFC) were used to obtain micro- and nanocomposite asphalt binders. The addition of 5% sodium dodecyl sulfate (SDS) affects the emulsifying ability of MFC and the properties of the resulting binders. While SDS increases the emulsifying ability and reduces the viscosity of bitumen emulsions, its presence in the dried binders reduces the stiffness, yield stress, and rutting resistance of the resulting microcomposite binders.

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.
