Summary: Nanocomposites of HDPE and zinc oxide nanoparticles were successfully produced with improved thermal stability and mechanical properties through a green preparation method. The presence of pectin-organophilized filler significantly influenced the crystallization and degradation processes of HDPE, leading to enhanced fire properties as confirmed by thermogravimetric analysis. The interactions between HDPE, pectin, and ZnO were found to be crucial for the structural and performance properties of the composites, with the biopolymer reacting with ZnO via ionic interaction and hydrogen bonding.

Summary: A comparative study was conducted to remove hexavalent chromium from wastewater using synthesized nanoparticles such as chitin, chitosan, zinc oxide, and ZnO-chitosan composite. The results showed that the ZnO-chitosan nanobiocomposite had the highest uptake capacity for chromium (VI). The optimal conditions for adsorption were found to be a concentration of 20 ppm, a dosage of 0.5 g/l, pH 3, and a time of 60 min.

Summary: This study reports on the adsorption of tetracycline using magnetic chitosan as the adsorbent. The highest adsorption capacity was achieved at pH 7.0, and the efficiency of the adsorbent depended on pH, initial concentration, and dosage. Ionic strength significantly affected the process. The Sips and Elovich models provided the best fit for the experimental data, indicating heterogeneous surface adsorption predominantly through chemical mechanisms. The adsorption of tetracycline was governed by hydrogen bonds and cation-pi interactions, and the incorporation of magnetite on the chitosan surface enhanced its removal efficiency. Thermodynamic parameters suggested a spontaneous and exothermic process. Magnetic chitosan proved to be effective in tetracycline removal even after multiple adsorption/desorption cycles.

Summary: The demand for new biocompatible materials to replace invasive materials in biomedical applications has led to the development of four formulations based on polycaprolactone and polylactic acid incorporated with zinc oxide nanoparticles and tea tree essential oil. The synthesis of zinc oxide nanoparticles resulted in spherical particles with an average size of 11 +/- 2 nm. Fourier Transformed infrared spectroscopy confirmed the presence of characteristic functional groups in each composite component. The study showed that the inclusion of tea tree essential oil and zinc oxide nanoparticles resulted in smooth surfaces, while membranes containing only one of these components exhibited porous morphologies. Histological implantation demonstrated the biocompatibility and biodegradability of the membranes after 60 days.

Summary: In this study, zinc oxide nanoparticles were synthesized using aqueous solutions at ambient temperature and 70 degrees C. The synthesized nanoparticles were analyzed using various techniques, and the results showed that temperature, mixing method, and stoichiometric ratio had significant effects on the particle size and morphology. Temperature also played a role in converting precursors into a single-phase compound. Furthermore, the calcination process had a significant impact on the crystal size of the synthesized particles.
