Summary: An experimental study was conducted on fouling characteristics of Water-CaSO4 solutions to heat transfer surfaces, showing that fouling can enhance heat transfer when rotational bulk solution Reynolds number (Re) is high without bulk precipitation. Under surface crystallization (SC) conditions, fouling resistance (R-f) and fouling rate (dR(f)/dt) decrease with increasing Re, while the presence of bulk precipitation (BP) significantly increases fouling rate and alters fouling mechanisms.

Summary: A novel membrane bioreactor (MBR) called ABGMBR was developed to improve pollutant removal and reduce membrane fouling. Compared to the control MBR (AGMBR), the ABGMBR system had higher pollutant removal rate and longer operation time. The ABGMBR system effectively reduced the content of pollutants on the membrane, resulting in the formation of a porous and loose cake layer and a slow increase in transmembrane pressure. The extended Derjaguin-Landau-Verwey-Overbeek theory suggested that the aggregation and adhesion of foulants on the membrane were greatly inhibited in ABGMBR.

Summary: This study found that the molecular structure rather than molecular weight of polysaccharides influenced the fouling behavior of reverse osmosis membranes. Branched-chain polysaccharides were more likely to cause severe membrane fouling and form thicker foulant layers on membrane surfaces compared to straight-chain polysaccharides. Additionally, the presence of Ca2+ had a significant impact on the fouling behavior of straight-chain acid polysaccharides but not on branched-chain polysaccharides or neutral polysaccharides.

Summary: By studying the fouling mechanisms of anionic polyacrylamide (APAM) in high-salinity environments, it was found that both divalent cations Ca2+ and Mg2+ aggravated membrane fouling. Compared to hydrated Mg2+, hydrated Ca2+ has a larger charge density and can form regular porous complexes with APAM carboxylate, resulting in weaker osmotic pressure. Therefore, lower fouling resistances and higher flux recovery rates were achieved in the case of Ca2+.

Summary: Chemical injection is an effective method to enhance oil recovery, and this study focuses on the interfacial activity of halogen-free ionic liquid-based catanionic surfactants. The results demonstrate that the synthesized surfactant with medium-chain ionic liquid (n=8) and sodium dodecyl sulfate has higher interfacial activity, lower crude oil-brine interfacial tension, and good wettability alteration. Moreover, the adsorption density of this surfactant onto the dolomite surface is considerably lower compared to the control experiment. The findings suggest that this catanionic surfactant has great potential for future chemical enhanced oil recovery applications.

Summary: Acid stimulation can cause formation damage due to incompatibility between the injected acid and crude oil, resulting in stable emulsions and acid sludge. This study found that crude oil properties, such as TBN, CII, asphaltene to resin ratio, and aromaticity, affect emulsion stability more than the pH value of the spent acid. The interaction between acid and crude oil is closely related to the characteristics of the interfacial film.

Summary: This study investigates the formation and stability of emulsions by measuring the colloidal instability index (CII) under ambient and reservoir conditions. The research finds that when CII is greater than 1.059, the formed emulsion is more stable as a result of the excessive instability of asphaltene. However, when CII is below 1.059, the emulsion tends to be less stable. Higher pressures enhance the stability of the emulsion.

Summary: This study investigates the most significant removal mechanisms of shear force, rolling, and rebound for asphaltene deposits under field operating conditions. The findings reveal that the removal of asphaltene is controlled by shear force, rolling, and rebound under geological conditions, while the impact of oil properties, casing diameter, and casing material is negligible. Additionally, larger asphaltene particles have a higher possibility of removal. The sticking probability is examined to calculate the proportion of precipitated asphaltene particles that will ultimately attach to the casing surface.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
