Summary: This study aimed to prepare hydroxyapatite (HA) with potential antibacterial activity by incorporating different metal ions during the hydrothermal synthesis. The results showed that metal ions did not affect the formation of HA phases but caused crystal structure distortion and reduced crystallinity. Nanoapatites containing Cu2+, Mg2+, and Zn2+ ions exhibited antibacterial activity, with Cu2+ ions showing the best effect. Furthermore, Cu2+-doped nanoapatites exhibited cytotoxicity, while Mg2+ and Zn2+ doped nanoapatites were biocompatible at low concentrations but became cytotoxic as the concentration increased.

Summary: In this study, cobalt oxide (Co3O4) nanoparticles were prepared via the hydrothermal method at different temperatures (120°C, 140°C, and 160°C). Cobalt nitrate hexahydrate and potassium hydroxide were used as the precursor and precipitating agent, respectively. The size of nanoparticles was controlled by adjusting the precursor concentration, and it was found that the particle size increased at higher temperatures. Nanoparticles with sizes ranging from 13.62 nm to 17.81 nm were successfully obtained. SEM results revealed nonuniform distribution of nanoparticles and sharp grain boundaries. Electrical characterization confirmed the semiconducting behavior of the material, as the resistivity decreased with increasing temperature. Moreover, the Co3O4 nanoparticles showed excellent detection ability for hydrogen peroxide (H2O2) according to the electrochemical measurements.

Summary: The redox chemistry of tellurium was investigated through the synthesis and characterization of tellurium catecholate complexes. The complexes showed stable adduct formation with organic oxidants, leading to ligand oxidation upon heating. The study revealed lower bond orders of tellurium N-oxide compared to catechol derivatives, suggesting higher reactivity of ligands towards oxidation than the tellurium center.

Summary: Aerogels are highly porous and ultralight materials with great potential for various applications. In this study, compounds were synthesized using graphene oxide (GO) and nanocellulose fibers (NFC) through a carefully designed hydrothermal reduction process. Two drying techniques, lyophilization and oven evaporation, were employed to obtain cryogel and xerogel materials, respectively. The results showed that cryogel dried by lyophilization had the best applicability due to its structural flexibility, while xerogel dried through oven evaporation resulted in a rigid and disintegrated compound. The developed cryogel exhibited promising characteristics such as high porosity, low shrinkage rate, light weight, and electrical conductivity, making it suitable for various applications including pressure sensors and electromagnetic shielding.

Summary: In this study, we investigated the electrochemical detection of dopamine in biological samples using a strontium pyrophosphate/hexagonal boron nitride composite. The combination of multiple active sites in the composite resulted in excellent physicochemical features, allowing for successful dopamine detection. The fabricated nanocomposite modified electrode demonstrated low resistance charge transfer, low detection limit, wide linear range, high sensitivity, and acceptable selectivity. The suggested nanocomposite also showed good recovery range for precise and quantitative dopamine measurement in human urine and BSA samples, demonstrating its real-time applicability.
