Summary: Salt-extracted canola protein isolate (CPI) was used to develop concentrated canola oil-in-water emulsions, showing gel-like structure with higher storage moduli than loss moduli. Addition of salt or vinegar reduced viscosity and gel strength of emulsions, while the presence of both led to non-flowing strong gel structure with higher viscosity. Heat treatment led to increased gel strength due to CPI thermal denaturation.

Summary: This study focuses on the spray characteristics of water-in-diesel emulsion, finding that the emulsified fuel has a wider spray angle and is prone to droplet puffing/microexplosion, resulting in more severe droplet deformation. As the water content increases, the average diameter of the droplets also increases, indicating that the spray droplets may undergo puffing/micro-explosion in a short period of time.

Summary: The study investigated the effects of different concentrations of acetylated cassava starch (ACS) on the physical and rheological properties of multicomponent emulsion-based products at specific pH values. Results showed that increasing ACS concentrations enhanced particle size, apparent viscosity, and rheological moduli of the products. However, higher ACS concentrations could lead to larger aggregations and coarser textures, impacting visual appearance and overall acceptability negatively. Additionally, acidic conditions promoted droplet aggregation while neutral conditions had no effect.

Summary: This study investigates the microstructural changes and their effects on rheological and drying properties of ceria-based suspensions at different pH values. The suspensions are classified into four zones based on pH values, with well-dispersed or aggregated states of ceria particles discerned by zeta-potential magnitude and condensation reaction at high pH. Suspensions with well-dispersed particles exhibit transition between shear-thinning and Newtonian behavior, while suspensions with agglomerated particles show significant shear-thinning and thixotropic behaviors. The motion of particles within suspension droplets is quantified using multi-speckle diffusing wave spectroscopy, revealing distinct coffee-ring patterns for well-dispersed particles compared to aggregated particles during drying.

Summary: This review provides an overview of the use of poly- and perfluorinated alkyl substances (PFAS) in electronic products, trends in ewaste generation, PFAS exposure pathways during e-waste handling and processing, and the presence of PFAS in environmental and human samples collected near e-waste processing sites. The manufacturing processes of electronic components make recycling or materials recovery very difficult. Exposure to PFAS can occur through inhalation, ingestion, and dermal routes. However, it is challenging to directly associate adverse health effects from e-waste exposure with PFAS, as there are other contributing factors. Better monitoring and epidemiological studies are needed to assess the potential health risks of PFAS exposure at e-waste handling sites.

Summary: This study examines the thermal properties of municipal solid waste (MSW) components and their impact on temperature increases in gas and leachate in landfills. The study finds that heat generated during waste decomposition primarily affects the temperature of the leachate. Most waste components have low thermal conductivities and low thermal diffusivities, resulting in significant temperature gradients during warming up and cooling off stages.

Summary: Floating crude oil patches can separate from the main oil slicks depending on oil characteristics and sea conditions. The breaking tendency of smaller oil patches from the fresh crude oil slicks vary depending on oil type and thickness of the oil slick. These observations explain the conditions that lead to formation of highly stable oil patches at sea that can remain floating and travel long distances, some eventually depositing at beaches and in shallow waters as large oil patches.

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.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
