Summary: This study investigated the effects of different emulsion types, oil compositions, and oil fractions on the structure and lipid oxidation in emulgel systems. It was found that emulgels were more susceptible to oxidation compared to soybean oil, with water-in-oil emulgels showing higher oxidation resistance than oil-in-water emulgels. Additionally, the degree of unsaturation in the oil composition and oil fraction had significant impacts on lipid oxidation in the biphasic emulgel systems.

Summary: In this study, porous carbon electrodes were prepared by direct laser sintering on commercial polymer films, which can be used directly without any modification. Combined with a 3D-printed flow reactor, the amount of analyte required during the detection process was significantly reduced. Numerical simulations of analyte velocities under stirring and flowing conditions showed that flow detection is more conducive to improving detection sensitivity. The limit of detection for Pb2+ was found to be about 0.0330 mg/L, and the electrode exhibited good repeatability and stability.

Summary: A superhydrophobic copper foam containing re-entrant nanostructures was fabricated through anodization, electrostatic assembly of carbon nanotubes (CNTs), and grafting of nonafluorohexyltriethoxysilane (NFH-silane). By stacking multiple copper foams to form a columnar bed separator, the permeation channels can be controllably extended and the residence time of emulsified water droplets prolonged. When 30 pieces of copper foams were accumulated and the thickness of the stack was extended to 45 mm, the separation efficiency reached 99.14 %, and the permeation flux reached 31,500 Lm-2h-1 for separating surfactant-stabilized water-in-toluene emulsion.

Summary: This study investigated the effect of oil-in-water and water-in-oil emulsions with the same Span 80 emulsifier on flotation performance. By comparing the particle size composition and recovered water of concentrates using kerosene, water-in-oil, and oil-in-water emulsions as collectors, it was found that oil-in-water with 0.5 g Span 80 showed the highest concentrate yield and combustible recovery, while water-in-oil had higher ash content, flotation rate constant, and recovered water. These differences can be attributed to variations in the oil droplet composition of the emulsions, which affect the yields of coarse particles in the concentrates, and subsequently influence the recovery water and fine particle variation.

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: Metallophytes are plants that can tolerate extreme metal concentrations in soil. A study on the Dugald River gossan in Australia found that there was no direct relationship between the occurrence of metallophytes and prevailing soil metal concentrations. Crotalaria novae-hollandiae was identified as a strong polymetallic indicator-type metallophyte that can accumulate high concentrations of metals in its leaves.

Summary: This study investigated the simultaneous formation of oil-in-water (O/W) and water-in-oil (W/O) emulsions from the same raw materials using three-phase emulsification. Experimental results showed that the type of emulsion formed depended on the interaction between hydrophilic nanoparticles and the oil-water interface. When nanoparticles were attached to the interface, only O/W emulsion was obtained, while both emulsion types were formed when nanoparticles partially penetrated the oil phase. Additionally, the formation of both O/W and W/O emulsions could be independently controlled by adjusting non-thermodynamic parameters during preparation.
