Summary: The interaction between groundwater matrices and nanoscale zero-valent iron (NZVI) affects the mobility of NZVI. In this study, polyacrylic acid-stabilized NZVI and Mg(OH)2-coated NZVI were investigated as representative stabilizers for NZVI. The presence of divalent cations and humic acid induced aggregation and sedimentation of NZVI-PAA, while encountered groundwater electrolytes could not effectively provide electrostatic repulsion. However, sonication of the NZVI slurry with groundwater eliminated the sedimentation behavior. In comparison, the settling behavior of NZVI@Mg(OH)2 was hindered, and it exhibited higher mobility after adsorption sites of the sand surface were exhausted.

Summary: In this study, an integrated system of Fe-0 and hydrogenotrophic microbes mediated by nitrate (NMB-Fe-0) was established to remediate Cd(II)-contaminated sediment. The results showed that the system successfully immobilized and enriched Cd(II)(aq) on iron surface through the promotion of iron corrosion and increased biomineral production. The Cd(II)(aq) removal rate in the NMB-Fe-0 system was much higher compared to the NM-Fe-0 system, and the leachability of Cd(II) decreased significantly while the residual fraction increased.

Summary: Green synthesized nano-zero-valent iron (GT-nZVI) has been shown to be an excellent material for in-situ soil remediation due to its stability and environmental friendliness. The transportability of GT-nZVI is affected by soil components (bacteria and phosphate), and phosphate can enhance the co-transport of GT-nZVI with bacteria at pH 6.0 but reduce its mobility at pH 8.0 due to cell-cell interactions. This study highlights the importance of considering surface property changes in complex environments for effective in-situ remediation.

Summary: Red mud, a polluting waste product emitted from the aluminum production industry, poses a potential threat to the environment due to its high alkalinity and complex chemical composition. In this study, granular porous zero valent iron (ZVI) adsorption reaction materials (Fe/GSBR) were prepared using red mud, straw, and bentonite. The optimal preparation conditions were determined through response surface analysis, and the properties of Fe/GSBR were characterized to demonstrate its porous and ZVI material nature. Additionally, the regeneration properties and toxic leaching of the materials were evaluated to ensure their environmental safety during use.

Summary: This study investigated the effect of hydrogenotrophic denitrification on cadmium (Cd(II)) removal and column life-span using hydrogen-autotrophic microorganisms and zero-valent iron (Fe-0) filled columns. The results showed that the nitrate-mediated bio-Fe-0 column had a higher Cd(II) removal efficiency and longer service life compared to the bio-Fe-0 and Fe-0 columns. This improvement was attributed to hydrogenotrophic denitrification, which caused more iron corrosion and more secondary mineral generation, providing more reaction sites for Cd(II) adsorption and immobilization. The distribution of reactive zone along the bio-Fe-0 column mediated by nitrate was found to be uneven, with the latter half part identified as a more active region for Cd(II) immobilization.

Summary: In this study, biochar was pyrolyzed with potassium ferrate to achieve porosity, graphitization, and iron doping simultaneously, resulting in the synthesis of nanoscale zero-valent iron loaded porous graphitized biochar. The nZVI/PGBC showed superior efficiency in removing 17 beta-estradiol compared to other materials, and the removal efficiency was affected by reaction conditions. The reaction mechanism involved the activation of persulfate by Fe2+ and Fe3+ redox reactions, with PGBC acting as a carrier for nZVI and a mediator for electron transfer in E2 degradation.

Summary: The study investigated the anti-staphylococcal activity of daptomycin and bacteriophage K, alone or in combination, against S. aureus and S. epidermidis strains. Best results were achieved when both agents were combined in high concentrations, with bacteriophage K showing effectiveness within a few hours depending on concentration. The combination was more effective against staphylococci, suggesting it may be a potential choice for biofilm-associated infections prevention or therapy.

Summary: This study aimed to develop optimal sustained-release moxifloxacin-loaded liposomes for the treatment of endophthalmitis. The active loading method (AL) showed higher drug encapsulation efficiency and antimicrobial potential compared to the dehydration-rehydration method (DRV), with longer drug retention in liposomes. The lipid composition did not affect drug release from DRV liposomes, but significantly altered drug loading and release in AL liposomes, indicating the importance of drug retention in liposomes for their activity.

Summary: Arsonolipids are a class of arsenic-containing compounds that have interesting biological properties. In this study, novel arsono-containing lipids were synthesized for the first time, where the alkyl groups are connected through stable ether bonds. These ether arsonolipids are expected to have higher chemical stability compared to conventional ester-linked arsonolipids. The preliminary in vitro assessment showed that the novel ether arsonolipids exhibited significant anticancer activity similar to that of conventional arsonolipids.

Summary: Untreated banana peel can efficiently adsorb cationic dyes but weakly adsorb anionic dyes. Conversion of banana peel into activated carbon through thermochemical treatment enhances the sorption capacity for both types of dyes. Among the tested activated carbons, the highest sorption capacity for both dyes was achieved when banana peel was modified with NaOH and pyrolyzed at 700 degrees C (BPAC-NaOH-700).

Summary: A dimensionless artificial neural network (ANN) is developed to simulate the remediation of organic waste-polluted muds. The mud is pretreated with synthetic seawater and anionic surfactant, and oxidized with ozone-rich gas in a semi-batch bubble flow column. Experimental data are used to calibrate a knowledge-based model (KBM) for generating simulated results to be used for ANN. The interpretation of ANN results shows that the removal efficiency of total organic carbon (TOC) is enhanced by increasing the initial TOC concentration in the solid phase, pre-treating mud with seawater/surfactant solution, increasing ozone concentration of injected gas, having moderate Reynolds number in the liquid phase, and high SDS concentration.

Summary: This research aims to evaluate the capacity of low-cost adsorbents fabricated from coffee wastes and diatomaceous earth to remove phenanthrene (PHE) from water, and to assess the role of pore structure on PHE sorption dynamics. The most efficient adsorbent chosen for further studies was CWAC-NaOH-800, which exhibited remarkable specific surface area, pore volume, and maximum PHE sorption capacity. The adsorbent could be regenerated with cold atmospheric plasma (CAP) and showed a recovery rate of around 35%. The dominant adsorption mechanism was believed to be the pi-pi interactions between hydrophobic PHE aromatic rings and CWAC-NaOH-800 graphene layers.

The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
