Summary: This study investigates the interference of dissolved organic matters (DOMs) in advanced oxidation processes (AOPs) treatment of pharmaceuticals in reverse osmosis concentrates (ROC). The results show that fulvic acid (FA) and humic acid (HA) have medium to strong inhibition effects. By increasing the dosages of the agents, all the DOMs can be efficiently decomposed into smaller molecules.

Summary: A novel Fe-CCS-g-beta-CD adsorbent was developed using zero-valent iron nanoparticles impregnated cross-linked chitosan grafted beta-cyclodextrin for the removal of cloxacillin from water. The adsorbent was characterized and optimized using various techniques and response surface methodology. The adsorption process was described by Freundlich isotherm model and pseudo-second order kinetic model. The adsorption and pH studies indicated the involvement of C-pi cation interaction and pi-pi interaction in enhancing the removal efficiency of cloxacillin.

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: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
