Titania Nanoparticles Doped Electrospun Membranes [PDF]

Archives of Metallurgy and Materials
Electrospun membranes exhibit very promising properties, such as high surface area, high surface area-to-pore volume ratio, high pore interconnectivity, and uniform pore distribution. Nanoparticles are a promising alternative for improving the properties

Medical and Dental Applications of Titania Nanoparticles: An Overview. [PDF]

Nanomaterials (Basel), 2022
Currently, titanium oxide (TiO2) nanoparticles are successfully employed in human food, drugs, cosmetics, advanced medicine, and dentistry because of their non-cytotoxic, non-allergic, and bio-compatible nature when used in direct close contact with the human body.

Development of coating formulation with silica–titania core–shell nanoparticles against pathogenic fungus [PDF]

Royal Society Open Science, 2018
In the present study, we developed an antifungal coating formulation using silica, titania and silica–titania core–shell nanoparticles individually. The idea behind the synthesis of core–shell nanoparticles was to use the mechanical strength of silica ...

Morphology and photoluminescence study of titania nanoparticles [PDF]

Colloid and Polymer Science, 2011
Titania nanoparticles are prepared by sol-gel chemistry with a poly(ethylene oxide) methyl ether methacrylate-block-poly(dimethylsiloxane)-block-poly(ethylene oxide) methyl ether methacrylate triblock copolymer acting as the templating agent. The sol-gel components-hydrochloric acid, titanium tetraisopropoxide, and triblock copolymer-are varied to ...

Titania Nanosheets as a Component of Reusable Substrates for Reproducible SERS Signal

Materials Proceedings, 2023
Titania nanosheets (TNS) represent 2D photocatalytic material, which can strongly bind with metal nanoparticles, and, therefore, materials based on it are promising in the development of reusable substrates for reproducible SERS. In the present research,

Hard and transparent films formed by nanocellulose-TiO2 nanoparticle hybrids. [PDF]

PLoS ONE, 2012
The formation of hybrids of nanofibrillated cellulose and titania nanoparticles in aqueous media has been studied. Their transparency and mechanical behavior have been assessed by spectrophotometry and nanoindentation.

Electrochemical investigations and antimicrobial activity of Au nanoparticles photodeposited on titania nanoparticles. [PDF]

Heliyon
Titanium oxide nanopowder (TiO2 NPs) was synthesized via anodization in 0.7 M perchloric acid then annealed in nitrogen at 450 °C for 3 h to prepared the Titanium Oxide Nitrogen annealed nanoparticles (TiO2 NPs-N2) powder as catalytic support. Using a photodeposition process, gold was added with isopropanol as a sacrificial donor and H[AuCl4] acid ...

Solvent Effects in the Deaggregation of Titania Nanoparticles

KONA Powder and Particle Journal, 2000
We report on the effect of alcohols in the acid peptization of aggregated titania nanoparticle produced from alkoxides. Peptization was studied in the presence of each one of the following alcohols: methanol, ethanol, propanol and isopropanol. We find that the final particle size is correlated to the dielectric constant of the peptizing medium. Kinetic
