Summary: We examined the stability of SiO2 and Al2O3 nanoparticles in both deionized water and low-salinity water. The stability was influenced by dispersion techniques and surfactant addition. SiO2 showed better stability due to its hydrophilicity, while Al2O3 tended to aggregate in low-salinity water. Various dispersion methods were applied to Al2O3, and the best stability was achieved with cationic and nonionic surfactants at pH 2.

Summary: This research compares the performance of two fine-emulsification systems and one conventional ultra-low interfacial tension (IFT) system in heavy oil recovery. The results show that fine-emulsification systems can generate more stable emulsions and achieve higher oil recovery rates compared to the ultra-low IFT system in certain conditions. However, the difference between the two systems becomes less significant as the water-oil viscosity ratio increases.

Summary: Liquid nanofluid (LNF) can be transported in nano-scale pores efficiently without excessive adsorption, increasing oil recovery efficiency. During the imbibition process, with wettability alteration and proper interfacial tension, LNF displaces oil more effectively. The higher retained permeability reduces flow resistance and energy consumption while indirectly increasing production.

Summary: This study used microfluidics to observe the fluid flow phenomenon in blind-ends and analyzed the oil displacement mechanism in blind-ends. The results showed that the width of blind-ends affected the displacement efficiency, and heavy oil was more difficult to displace. Polymer flooding and surfactant reduced capillary force and improved the displacement of light oil.

Summary: This study developed an experimental system to simulate the mechanism of percolation, energy storage, oil displacement, and flowback of chemical agents in the hydraulic fracturing assisted oil displacement process. The research showed that this technology could effectively enlarge the swept volume, improve the oil displacement efficiency, and replenish formation energy. The degree of formation energy deficit was found to be the main factor affecting the effective swept range of chemical agents.

Summary: SiO2 nanofluid alternating with CO2 injection can be used as an effective substitute for the conventional water alternating gas (WAG) process in oil flooding experiments. The SiO2 nanofluid demonstrates excellent stability and emulsification properties, making it a promising medium for petroleum-related applications. Smaller slug sizes and an optimal slug ratio can delay the breakthrough time and enhance the effectiveness of nanofluid alternate CO2 flooding for enhanced oil recovery (EOR). Additionally, lower permeability rock cores show higher oil recovery rates.

Summary: Nowadays, oil companies use nanofluid flooding to increase oil production from reservoirs. In this study, a three-dimensional porous medium filled with oil was simulated to extract oil using a multiphase flow in porous media. The finite element method was employed to solve the nonlinear partial differential equations of continuity, energy, Darcy's law, and nanoparticle transport. The results showed that SiO2 had the best oil recovery factor (ORF) compared to other nanoparticles, with an optimum volume fraction (VF) of 4% at an inlet temperature of 353.15 K.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
