Summary: Surfactant-based oil recovery processes are used to lower interfacial tension and change the wettability of rock in immiscible displacement processes. The key factors affecting this process are temperature, salinity, pH, surfactant concentration, and adsorption. Chemical enhanced oil recovery (cEOR) processes combine surfactants with other chemicals to exploit their synergy. This review study categorizes the role and displacement mechanisms of surfactants and discusses key factors for analyzing fluid displacement in porous media.

Summary: Through analyzing the properties of ASP produced water in Daqing Oilfield, it was found that the critical micelle concentration of ASP produced water is greatly affected by pH and slightly affected by temperature. The addition of polymer increases the viscosity of produced water and enhances its stability. The presence of inorganic salts promotes the formation of surfactant micelles in ASP produced water, further enhancing its stability.

Summary: Surfactants are widely used in various industries such as household cleaning, personal care, and cosmetics. However, most of the surfactants currently in use are derived from fossil fuels and are environmentally unfriendly and toxic. Therefore, there is a need for greener alternatives. The determination of the critical micelle concentration of surfactants is crucial for their development as analytical tools and commercial materials. A fast and cost-effective method using dried drop coffee ring image analysis is proposed for determining the surfactant critical micelle concentration.

Summary: This study determines the costs of using CO2 capture technologies in the refining and petrochemical sectors. Depending on the process and method used, CO2 emissions costs of EUR 30 to 40 per ton of CO2 can be avoided. Advanced low-temperature CO2 capture technologies may not provide significant benefits compared to conventional technologies. An analysis estimated a reduction potential of about 0.5-1 Gt/yr for the oil and gas industries using short- and long-term technologies. The integration of CO2 capture into the oil production process helps reduce costs and emissions.

Summary: Nanomaterials, specifically silica-graphene quantum dots (Si-GQDs), have been synthesized and dispersed in water to form nanofluids. These nanofluids exhibit significant reduction in interfacial tension and wettability alteration, leading to enhanced oil recovery from carbonate reservoirs. The experimental results show that the nanofluids formulated with 1000 ppm Si-GQDs in distilled water enable an additional 14.4% oil recovery due to the reduction in interfacial tension and contact angle.

Summary: In this study, experiments were conducted to investigate the distribution of sulfur in the products during thermal degradation of vacuum residues under different operating conditions. Three vacuum residues with different sulfur contents were selected, and the effects of pressure and temperature on product yields and properties were studied. The results show that increasing temperature results in increased sulfur distribution in liquid fuel and reduced sulfur distribution in petroleum coke. In addition, the reaction temperature has an effect on the yields of light coker gasoil.

Summary: This study investigates the effects of organic amines (methylamine, dimethylamine, amylamine) and urea on the kinetics of CO2 + CH4 hydrate formation through molecular dynamics simulations. The results show that the presence of methylamine, dimethylamine, and their mixture is more kinetically efficient in promoting hydrate formation. These molecules can also induce guest gases to be located inside the formed cages. However, the addition of urea does not exhibit the same efficiency as the combined methylamine and dimethylamine.

Summary: Shale formations can swell when exposed to water-based drilling fluids, presenting challenges for drilling operations. One solution is to modify drilling mud with shale swelling inhibitors. In this study, Dodecyltrimethylammonium Chloride (DTAC) was investigated as a new shale stabilizer and swelling inhibitor. Various tests were performed to evaluate its effectiveness, and DTAC showed good inhibition power in controlling and reducing the swelling of shale and bentonite samples. It is also compatible with other additives in drilling fluids and exhibits stronger function compared to other inhibitors like CTAB and NH4Cl.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

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.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

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.
