Summary: This study investigated the adsorption of heavy metals (Cd and Cr) from industrial wastewater using a series of Ca-substituted nickel zinc nanoferrites (CaxNi0.4Zn0.6-xFe2O4 (x = 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6)) (CNZNFs). The effect of calcium doping and contact time on the adsorption of cadmium and chromium ions was examined, and the prepared nanoadsorbents showed high removal efficiencies for both Cd (98.25%) and Cr (51%) ions. Structural analysis confirmed the formation of spinel structured nanoparticles with varying crystallite size and porosity depending on the calcium concentration. The adsorption data was well fitted by the pseudo second order kinetic model and Langmuir isotherm model, with high adsorption efficiencies of Cd (128.20 mg/g) and Cr (23.54 mg/g) observed. The Langmuir isotherm model showed better fitting than the Freundlich isotherm model due to higher correlation coefficients for both heavy metals.

Summary: In this study, microorganisms with high resistance to lead ions were isolated and evaluated for their efficiency in removing lead ions from wastewater through biosorption. The optimized conditions for biosorption of Pb (II) were determined, and the biosorption efficiency and capacity of the isolated Brevibacillus strain were analyzed. Surface characterization and analysis of key functional groups involved in biosorption were conducted. The results showed that the biomass of Brevibacillus can be used as a promising biosorbent for the removal of metals, including lead, from wastewater.

Summary: In this study, the adsorption and subsequent desorption of titanium dioxide (nTiO2) and zinc oxide (nZnO) nanoparticles, as well as polyethylene microplastics (MPs), in aquatic media were investigated. The results showed that nZnO had a faster adsorption rate than nTiO2, but nTiO2 had a higher adsorption extent on MPs. The low adsorption of nZnO could be attributed to the partial dissolution of zinc from nZnO, which resulted in soluble zinc complexes not being adsorbed on MPs. The adsorption process was found to be controlled by physisorption for both nTiO2 and nZnO. Meanwhile, the desorption of nTiO2 was low and independent of pH, while the desorption of nZnO was pH-dependent, with a higher desorption rate at a slightly acidic pH. These findings provide insights into the complex interactions and fate of MPs and metal engineered nanoparticles in the aquatic environment.

Summary: In this study, an adsorption process utilizing a novel hematite-based nanomaterial loaded onto biochar was used for the remediation of toxic cadmium ions from aqueous media. Experimental results showed that the hematite-loaded Saccharum munja biochar and Saccharum munja biochar were more effective in Cd(II) removal compared to raw Saccharum munja. The thermodynamic studies indicated the adsorption process was feasible, spontaneous, and endothermic, with physiosorption being the predominant mechanism.

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.
