Summary: This study demonstrates a microwave-assisted method for synthesizing a novel crosslinked nanocomposite from TiO2NP-chitosan and ZrO2NP-chitosan for the removal of trivalent gadolinium and samarium ions from water. The synthesized nanocomposite exhibits good sorption properties controlled by various factors, with maximum uptake capacities achieved at pH 7. Models used to describe the adsorption processes agree with pseudo-first order and Langmuir-Freundlich isotherms.

Summary: A solid adsorbent based on Chinese gallotannin and chitosan was synthesized and applied for adsorption of rare and scattered metals from simulated zinc plant leachates. The adsorption mechanism involved Schiff-base condensation and phenol-formaldehyde reaction between gallotannin and chitosan. Increase in pH enhanced the adsorption capacity of immobilized Chinese gallotannin (ICGT), and temperature had a limited effect on the adsorption capacity of the adsorbent. The adsorption of the metals followed a quasi-second-order kinetic equation with chemisorption as the mechanism, and Langmuir isotherm model was found to fit the adsorption data well.

Summary: This study utilized a synthesized cross-linked magnetic chitosan with graphene oxide beads for the removal of perchlorate from wastewater, showing that adsorption can occur over a wide range of pH and follows a pseudo-second-order kinetic model and Langmuir adsorption isotherm. The findings suggest that the adsorption process is exothermic and spontaneous, with the perchlorate adsorbent effectively regenerated by a 0.1% NaCl solution.

Summary: Given the large amount of harmful pharmaceuticals being released into the water stream, it is crucial to eradicate or reduce these chemicals to a minimum permissible limit. This study reports the fabrication of a magnetic guar gum graphene oxide nano-composite (mGG/GO NC) for the adsorption of ciprofloxacin from wastewater. Various techniques were used to characterize the guar gum and the nanocomposite, and it was found that the adsorption process followed the pseudo second order model and Langmuir isotherm model. The nanocomposite exhibited high adsorption capacity and recyclability, potentially due to a synergistic effect of multiple interactions in the adsorption mechanism.

Summary: Micropollutants (MPs) in wastewater pose environmental challenges and require advanced treatment methods for removal, such as dosing powdered activated carbon (PAC) before membrane filtration. Research shows that the efficiency of MPs removal is influenced by the PAC concentration in the stock suspension, with lower concentrations leading to better removal. Therefore, maintaining a low PAC concentration in the stock suspension can enhance the overall performance of the treatment process.

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.
