Summary: This study presents a novel approach to evaluate wax deposition inhibitors by measuring the differential pressure in a test tube. The results showed that the use of inhibitors prolonged the time until the maximum differential pressure of 1000 mbar was reached and reduced the wax particle size and agglomeration tendency.

Summary: Plant-based, edible water-in-oil biphasic gels (bigels) were developed and characterized in this study. The addition of monoglycerides (MG) in the oil phase and the ratio of oil gel to water gel were evaluated. The bigels were self-supporting and visually homogeneous, except for a specific formulation with phase separation. The mechanical properties of the bigels were mainly determined by the oil gel phase, and the addition of MG increased their solid fat content.

Summary: The study investigated the use of cheaper organic wax inhibitors obtained from crude palm oil and crude palm kernel oil to improve the flow of crude oil and reduce viscosity. Results showed that these palm-based additives were more effective at reducing the viscosity of the crude oil compared to commercial wax inhibitors like triethanolamine and ethylene vinyl acetate.

Summary: Hydrates and waxes are major flow assurance issues in deep-water multi-phase transport units in the energy industry. This study investigates the anti-aggregation performance of an eco-friendly amphoteric surfactant, CAPB, in wax-containing oil-water systems. The concentration of CAPB and wax content synergistically influence its anti-aggregation performance. Adding 1.5 wt% CAPB effectively inhibits hydrate formation and improves flow in oil-water systems without wax. Adding 2.0 wt% CAPB slows hydrate growth rate and reduces inter-particle aggregation in waxy oil-water systems.

Summary: A novel algorithm for calculating the wax precipitation temperature (WPT) of wax-based warm mix asphalt binder was proposed. The study investigated the wax precipitation process in asphalt, as well as the effects of aging, cooling rate, and shear rate on wax precipitation characteristics. The findings suggest that the refined WPT algorithm has higher precision and reproducibility than the traditional viscosity method, and that wax precipitation in asphalt is influenced by aging, cooling rate, and shear rate.

Summary: The study found that the application of glyphosate (2592 g a.i. ha(-1)) and the sequential application of glyphosate can result in higher levels of intoxication. However, the combination of B. subtilis BV02 with glyphosate (2592 g a.i. ha(-1)) can prevent losses in relative chlorophyll a and b values and the total chlorophyll index. Soybean yield is reduced when plants are subjected to a sequential application of glyphosate.

Summary: In this study, the influence of lacquer wax content and whipping time on overrun was investigated. It was found that an appropriate amount of wax and whipping time can enhance crystal dual stabilization and close packing, resulting in improved overrun. Polyglycerol polyricinoleate (PGPR) aided in absorbing and improved the contact angle, promoting adsorption at the A-O interface. Partial substitution of high-melting fat palm stearin (POs) in 8 wt% oleogel produced oleofoams with increased melting point, structural strength, and beta'-form crystal, enhancing storage and temperature stability. The oleofoam exhibited a maximum overrun of 189% and maintained decorating shape for over 15 days at ambient temperature, demonstrating potential in low-fat food applications and other delivery systems.

Summary: The practice of replacing traditional polymer modifiers with waste plastics has gained increasing interest in recent years, especially with polyethylene-based plastics showing promising potential in bitumen modification. Additionally, the chain length of waxes, the form of added waste polyethylene, and the blending protocol have critical effects on the properties of the mixture.

Summary: Two organic-inorganic hybrid nonlinear-optical crystals, [C5H6O2N3](2)[IO3](2) and [C5H6O2N3][HSO4]center dot H2O, were successfully synthesized in aqueous solution using 2-amino-3-nitropyridine as the cation and different anions of [IO3](-) and [HSO4](-). The crystals, crystallized in noncentrosymmetric space groups of P2(1) and P2(1)2(1)2(1), exhibit second-harmonic-generation effects and large birefringence. This work provides a new feasible path for the rational design of high-performance organic-inorganic hybrid materials.

Summary: This study compared PM18-g-NSiO2 prepared by an amidation reaction with PM18/SiO2 prepared by the solution blending method. The characterization results showed that a chemical bond was formed between PM18 and NSiO2, and PM18-g-NSiO2 exhibited a more regular morphology structure. The rheological tests demonstrated that the optimal concentration for both PM18-g-NSiO2 and PM18/SiO2 was 300 mg/kg, but the temperature decrease of PM18-g-NSiO2 was 19°C, while PM18/SiO2 was only 13°C. The addition of PM18-g-NSiO2 resulted in a lower viscosity and more regular and smaller wax crystal structure compared to PM18/SiO2. The study concluded that differences in synthesis methods can affect the coverage of polymer on nanoparticle surfaces.

Summary: In recent years, wax-based warm mix additives have been used to lower the construction temperatures of asphalt, resulting in substantial energy savings and promoting energy sustainability. This study introduced a new method to inhibit the premature precipitation of these additives by using wax inhibitors (WIs) to improve compatibility. The effects of WIs on the cracking resistances of warm mix asphalts were investigated, and it was found that the addition of WIs reduced the wax precipitation temperature (WPT) and improved the compatibility of additives. The WIs also enhanced the elasticity and resistance to rutting and fatigue at high and intermediate temperatures, as well as improved the cracking and thermal fatigue resistances at low temperatures.

Summary: The rechargeable aqueous zinc-iodine batteries (AZIBs) with a multipurpose sponge-like porous matrix of a metal-organic gel show superior electrochemical performance due to limited iodine diffusion, leading to high capacity retention and long-term stability even after 1500 cycles. Prototype flexible band-aid-type AZIBs also demonstrate promising performance in real-scale wearable applications.

Summary: Octahedral-shaped Cu2O nanocrystals were synthesized and used as catalyst for benzylic sp(3) C-H bond oxidation. The oxidation of Cu2O to CuO can be avoided in the dark or inert atmosphere or continuous flow of oxygen gas. The proposed reaction mechanism involves activation of O-2 molecule through single electron transfer (SET) mechanism on the (111) facets of semiconducting Cu2O NCs in light.

Summary: Fe3O4@L-Arginine and Fe3O4@L-Histidine nanoparticles were synthesized and used as catalysts for sequential Knoevenagel condensation and Michael addition reactions. Optimized reaction parameters resulted in high yields of 97% in Knoevenagel adducts and 70% in Michael products under solvent-free conditions at 80 degrees C. However, Fe3O4@L-Histidine NPs did not show any catalytic activity for the sequential Michael addition. The reasons behind the high activities of Fe3O4@L-Arginine NPs have been discussed, and the catalyst could be reused for 5 cycles with consistent activity and selectivity. This optimized protocol offers high isolated yields, cost savings in solvents, and falls within the domain of green chemistry.
