Summary: The study demonstrated the utilization of an electric field generated by high voltage discharge plasma over a liquid water surface containing glycine compound to synthesize TiO2 nanoparticles. The applied voltages, pulse numbers, and repetition rates significantly influenced the decomposition reaction of glycine compounds and electrode erosion. The UV-vis spectra and HRTEM images confirmed the formation of TiO2 nanoparticles and TiC as nanoparticle products, suggesting that this process has potential for advanced nanoparticle synthesis technology.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: This study successfully synthesized titanium dioxide nanoparticles using rutin as a mediator and evaluated their antibacterial, antidiabetic, and antioxidant properties. The results showed that the biosynthesized nanoparticles exhibited good antioxidant activity and moderate inhibition of alpha-amylase and alpha-glucosidase. Furthermore, these nanoparticles showed no toxicity and had comparable properties to chemically prepared nanoparticles.

Summary: Engineered nanomaterials with unique properties may pose health and environmental concerns. A study using zebrafish PMR test for toxicity evaluation, along with automated dechorionation, showed improved bioavailability of nanomaterials. Behavioral and toxicological responses were measured at 30-31 hours and 120 hours, revealing behavioral responses for 13 nanomaterials and acute toxicity levels below the maximum test concentration for 9 nanomaterials.

Summary: A stable colloid of titanium dioxide nanoparticles was prepared at neutral pH to immobilize horse radishperoxidase, resulting in highly active protein microarrays with 3-dimensional nanoconfiguration. The sensitivity of the protein microarray based on peroxidase-titanium dioxide nanoparticles was nearly 20 times higher than conventional technology.

Summary: The biogenic titanium dioxide nanoparticles (TiO2 NPs) synthesized using the seed extract of Abelmoschus esculentus (AE) as reducing and capping agents demonstrated high photocatalytic activity in the degradation of methylene blue dye. Characterization of the synthesized TiO2 NPs confirmed the successful synthesis of spherical anatase phase nanoparticles, with phytochemicals in the extract playing a role in capping and stabilization. The synthesized TiO2 NPs showed uniform size distribution and achieved over 80% degradation in 240 minutes of irradiation, outperforming commercial TiO2 NPs.

Summary: Developing efficient and stable visible light active photocatalyst has significant environmental applications. In this study, TiO2 nanoparticles were functionalized with salicylic acid and sensitized with chlorophylls, resulting in improved degradation efficiency and catalyst stability for the degradation of Ciprofloxacin under visible light. The degradation followed pseudo-second-order kinetics and was reduced in the presence of other scavenging species in the wastewater matrix system.

Summary: Hybrid eco-friendly nanocomposite films were fabricated by blending high-methoxyl pectin, gelatin, TiO2, and curcumin through the solution casting method. The addition of TiO2 nanoparticles and curcumin affected the surface morphology, roughness, and compactness of the films. Moisture content, water solubility, and light transmittance reduced with increasing TiO2 nanoparticle content.

Summary: This work focuses on synthesizing hybrid nanocomposite electrode materials for supercapacitor applications. The performance of different hybrid electrode materials, such as MoS2/CNTs, TiO2/CNTs, and MoS2/TiO2/CNTs, was enhanced by incorporating carbon nanotubes (CNTs) into MoS2 and TiO2. The synthesized MoS2/TiO2/CNTs exhibited superior electrochemical performance compared to other hybrid electrode materials, with a higher specific capacitance and lower overall impedance. It also displayed good cycling stability and high energy and power densities.
