The titanium oxide (TiO2) nanoparticles were prepared using the sol-gel technique. calcination temperature (650, 850) has produced different TiO2 structures (anatase and rutile), effect of particles was studied. on structural properties nanomaterial. Furthermore, at room-temperature casting process used to create a PVA/TiO2 nanocomposite with phases. showed results X-ray diffraction (XRD) that ...

Adviser: Srivatsan Kidambi Titanium dioxide (TiO2) nanoparticles are one of the most highly manufactured nanomaterials in the world with applications in copious industrial and consumer products. The liver is a major accumulation site for many nanoparticles, including TiO2, directly through intentional ingestion or indirectly through increased environmental contamination and unintentional ingest...

In this study, an anatase/rutile mixed-phase titanium dioxide (TiO2) hierarchical network deposited with Au nanoparticles (Au/TiO2 ARHN) was synthesized using a facile hydrothermal method followed by a simple calcination step. Such a unique structure was designed for improving the light harvest, charge transportation/separation, and the performance of photo-electro-chemical (PEC) cells. The pro...

Titanium dioxide nanostructures are formed by a simple one-stage method of thermal oxidation titanium in the temperature range 700-900 o C. The structures were studied high-resolution electron microscopy and X-ray diffraction. It is shown that, depending on temperature, form crystallites, granules, dendrites TiO2-rutile surface metallic titanium. proposed promising for large-scale creation adva...

Surface modification with a nanomaterial has been confirmed to be an effective strategy enhance the visible-light photodegradation efficiency of titanium dioxide nanoparticles (TiO2-NPs). In this regard, we used silver as additive into TiO2-NPs improve their activity under visible light irradiation. Here, novel and eco-friendly process was developed prepare Ag-doped TiO2 nanohybrid named photon...

Catalytic and photocatalytic reactions of (2-chloroethyl) phenyl sulfide (2-CEPS), a mimic of bis (2-chloroethyl)  sulfide (i.e. Sulfur mustard) were studied on the surfaces of titanium oxide. TiO2 nanoparticles (anatase, rutile and mixture of 80% anatase/20% rutile) along with bulk TiO2 were tested as reactive sorbents for reaction of 2-CEPS at room temperature (25±0.5°C). Reactions were monit...

The new properties of engineered nanoparticles drive the need for new knowledge on the safety, fate, behavior and biologic effects of these particles on organisms and ecosystems. Titanium dioxide nanoparticles have been used extensively for a wide range of applications, e.g, self-cleaning surface coatings, solar cells, water treatment agents, topical sunscreens. Within this scenario increased e...

We have investigated the impact of titanium dioxide nanoparticles on the ionic contamination of liquid crystals. Nematic liquid crystals with high and low initial ionic contamination have been examined. It has been shown that titanium dioxide nanoparticles reduced the ion density of liquid crystals with high initial ionic contamination from 134.5 × 1012 cm-3 to 63.2 × 1012 cm-3. In the case of ...
