Summary: The stress corrosion behavior of X70 pipeline steel under the combined action of SRB and constant load was investigated. It was found that plastic stress and SRB greatly increased the susceptibility of X70 pipeline steel to stress corrosion cracking (SCC). SRB promoted pitting corrosion, and the synergistic effect of SRB and plastic stress further enhanced the occurrence of pitting on the pipeline steel. Elastic stress did not play a significant role in promoting corrosion. The synergistic effect of tensile stress and SRB was explained from the perspective of corrosion thermodynamics.

Summary: Three gemini cationic surfactants with different hydrophobic tails were synthesized and confirmed spectroscopically. Surface tension measurements were conducted to examine their corrosion inhibition efficiency. It was found that the hydrophobicity and temperature affected their adsorption and micelle formation. The synthesized surfactants showed efficient affinity to mitigate steel corrosion, with GSBH exhibiting the highest inhibition efficiency of 94.5%. The adsorption of the inhibitors on C-steel was confirmed, and their behavior followed a modified Langmuir isotherm. The synthesized surfactants also showed affinity to mitigate sulfate reducing bacteria, with GSBO being the most effective.

Summary: Salt-resistant polymer flooding technology has been widely promoted in oilfields, however, the high mineralization and solid impurities in the water used for polymer configuration, as well as its incompatibility with formation water, often lead to scaling in the pipelines. Additionally, the presence of polymers and anaerobic conditions in buried pipelines create an environment that facilitates corrosion by microorganisms. This study investigated the corrosion behavior of sulfate reducing bacteria (SRB) on pipelines under CaCO3 deposition using different tests and analysis techniques. The results showed that the deposition layer provided an anaerobic environment for SRB, significantly increasing corrosion rate and promoting galvanic corrosion under deposition.

Summary: This study investigated the influence of different solvents (hexane, ether, chloroform, and methanol) on the corrosion of mild steel in 1 M HCl solution using seed extracts of Datura stramonium plant. The results showed high performance of the methanolic extract with a maximum inhibition efficiency of 94.2% at a concentration of 0.2 g L-1. The inhibitors were found to be of mixed type and preferentially blocked the active sites responsible for corrosion, which was confirmed by UV-visible spectroscopy and SEM/EDX analysis.

Summary: The study investigates the biofilm formation and corrosion of sulfate-reducing bacteria on a shale gas pipeline steel at different liquid flow rates. It finds that at low flow rates, the SRB biofilm thickens gradually, while at higher flow rates, the existing biofilm is stripped away leading to accelerated corrosion due to flow erosion. The study provides insights into the synergistic corrosion behavior between SRB and flow rate, which can be valuable for corrosion protection in shale gas fields.

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.
