Summary: This study achieved effective adsorption of GenX by using chitosan (CS) modified adsorbent. The prepared CS-DEO-APTES adsorbent showed high adsorption capacity and excellent stability. Kinetic and isothermal data revealed chemisorptive interactions between GenX and CS-DEO-APTES with a uniform distribution of adsorption sites. GenX-saturated beads were successfully regenerated multiple times. Density functional theory calculations indicated that electrostatic interactions primarily influenced the adsorption of GenX. These results highlight the effectiveness of the CS-DEO-APTES adsorbent for removing GenX from aqueous solutions.

Summary: Lead (Pb) is a highly toxic heavy metal that can enter the biological system through the food chain, and lead ion (Pb (II)) can be released into the environment from natural and anthropogenic sources. Among various remediation techniques, adsorption is considered effective for its economic and versatile properties. The study showed that the CS-AC-PVA composite beads have better adsorption capacity for Pb (II) compared to lone CS, AC, and CS-AC beads, with a 44% increase compared to CA-AC beads. The adsorption capacity of CS-AC-PVA beads for Pb (II) was highest at 25 degrees C, following the Freundlich isotherm model with increasing concentrations and decreasing temperatures. This demonstrates the potential of CS-AC-PVA composite beads as an adsorbent for environmental remediation of Pb (II) from aqueous solutions.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist.
