Summary: The influence of hydrophobic carnauba wax-based particles on the structure and hydrophobicity of chitosan coating films was investigated using Pickering emulsion. The results showed that micro-scale particles with nano-scale TiO2 uniformly distributed on their surface were formed. The hierarchical structure, hydrophobicity, and arrangement of the particles resulted in chitosan coating films with higher contact angle and lower sliding angle. The small particle coating film exhibited higher hydrophobicity than the large particle coating film due to the small particle size and the formation of more small gaps.

Summary: This research investigates the potential of using waxes as ingredients in food-grade water-in-oleogel emulsions without added emulsifiers. The study examines the effects of wax type, wax concentration, and water concentration on systems containing water, sunflower oil, and wax. The findings suggest that carnauba wax and beeswax can stabilize emulsions without additional emulsifiers if present in sufficient concentration.

Summary: In this study, a shape-stable hybrid emulsion gel (EGel/GO) was developed through Pickering emulsion polymerization, which combines sodium acetate trihydrate (SAT) and paraffin wax (PW). The polymer dual-phase cross-linking in EGel/GO enhances the material's shape stability, slows the loss of crystalline water in hydrates, and reduces supercooling. Addition of graphene oxide (GO) increases the optical absorption properties of EGel/GO-0.5, resulting in a high photothermal conversion efficiency of 89.1%. Furthermore, EGel/GO has high latent heat and no leakage or phase separation, making it an ideal choice for effective utilization of solar energy and building energy storage.

Summary: This paper investigated the formation, stability, rheological characteristics, and magnetic behavior of liquid paraffin oil-in-water Pickering emulsions stabilized by MCNC. The presence of 37-83 wt% magnetite in the hybrid was found to lead to the most stable emulsions. Additionally, MCNC-stabilized emulsions exhibited higher dynamic viscosity and better adsorption capabilities for toxic compounds like Cr(VI) compared to other hybrids.

Summary: This research focuses on the phase inversion emulsification of paraffin oil/high-density polyethylene wax (PEW) blend in water using mixed surfactant systems. The usage of gemini surfactants in the emulsification process is found to be more effective compared to monomeric surfactants. The results show that the change in water phase volume fraction at the phase inversion point is in accordance with the change in interfacial tension between the water phase and the oil phase. The usage of mixed monomeric/gemini surfactant systems leads to larger zeta potentials, comparable drop sizes, and higher long-term stability of the emulsions.

Summary: In this study, simple oil-in-oil emulsions were prepared using layered nanoparticles as stabilizers between silicone and castor oil. Layered double hydroxides with a shigaite-like structure were prepared by co-precipitation, followed by surface grafting with octadecyltrimethoxysilane in an apolar medium. The functionalized materials maintained their structure and morphology and showed good performance in controlling the hydrophobicity of the surface for application in oil-in-oil emulsions, improving their compatibility for dispersion in non-polar liquids.

Summary: The nonionic surfactant sucrose stearate C-1801 can form crystals at high temperature in oil, which then stabilize water-in-oil (W/O) Pickering emulsions. These emulsions show long-term stability even after undergoing multiple heating-cooling cycles and freeze-thaw cycles. The behavior of C-1801 as an emulsifier demonstrates its potential as a stabilizer for W/O food products.

Summary: The usual problem of meltable phase-change agents is their instability in form during heating, which can be solved by incorporating them into a continuous polymer matrix. This study demonstrates that molten paraffin wax forms a stable Pickering emulsion in an epoxy medium with the presence of asphaltenes extracted from heavy crude oil. The rheological studies reveal the viscoplastic behavior of the obtained dispersions at 25°C, which disappears upon heating and melting of the paraffin phase.

Summary: This study reports the first stable water-in-oil emulsions stabilized solely by a naturally occurring steroidal sapogenin. Concentrated emulsions with high internal water ratios can be obtained with low diosgenin concentrations, which significantly influence the microstructure and rheological properties. The emulsions exhibit excellent freeze/thaw stability and thermal stability, with the structural properties attributed to the combined action of diosgenin crystal shells and needle-crystals. This novel food grade emulsion demonstrates great potential for applications in food and biomedical-related fields.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
