New approaches of soft chemistry for preparation of nanostructured multifunctional composite coatings

Vinogradov A.V., Vinogradov V.V., Vinogradov A.V., Vinogradov V.V., Agafonov A.V., Institute of Solution Chemistry RAS, RU
In this work, we have obtained film heterostructures such as MeO/TiO2 possessing high photoactivity by low-temperature sol-gel method. We have succeeded in obtaining photoactive TiO2-based crystalline coatings, FeTiO3 and CoTiO3, without calcination and possessing an [...]

Nanosized titania reservoirs for epilepsy treatment

Kozina A., Espinoza K.A., Ortiz-Islas E., Rivero I.A., Lopez T., Instituto Nacional de Neurologia y Neurocirugia ‘MVS’, MX
Around 50 million people in the world suffer from epilepsy. Although there is no cure for this disease, with the right type and dosage of anti-epileptic medication the majority of patients can have their seizures [...]

Coatings of Polymers with TiO2 Nanoparticles by Sonochemical Method

Perkas N., Gedanken A., Bar-Ilan University, IL
The TiO2 films due to their photocatalytic properties are widely used for coating of polymers to impart them with the self cleaning properties. Although the titania films were thoroughly studied earlier the development of simple [...]

Visible Photoluminescence Emission from Chemically Synthesized MWCNT/TiO2 Hybrid Nanostructure

Paul R., Kumbhakar P., Mitra A.K., National Institute of Technology, Durgapur, IN
We report here a simple chemical precipitation process to synthesize a heterostructure of multi-walled carbon nanotubes (MWCNTs) and TiO2 (titania) nanoparticles of average size 3.5 nm. The hybrid structure has been characterized by high resolution [...]

Fabrication and Characterization of pH-Responsive, Nanoparticle-Attached Porphyrins for Singlet Oxygen Production

Li W., Courtney S., Gandra N., Ellis E.D., Tiyyagura P.T., Gao R., Jackson State University, US
The goal of this work was to understand if singlet oxygen (1O2) production from an immobilized dye could be regulated directly on support media such as titania and silica. Two types of pH- responsive, nanoparticle-attached [...]

Green Chemistry Derived Nanocomposite of Silver-modified Titania used for Disinfectant

Liu J., Ramirez I., Bashir S., Mernaugh R., Texas A&M University-Kingsville, US
A significant accomplishment of this study centers on developing nanocomposite (NC) materials via green synthesis (GS) techniques for inactivation of prokaryotes like Escherichia coli. The motivations are to: (1) implement fundamental research in nanochemistry for [...]

Tailored nanoscaled TiO2 dispersions for photocatalytic applications

Pilotek S., Tabellion F., Gossmann K., Buhler Inc., US
The use of the photocatalytic activity of nanoscaled anatase particles is intriguing. Whereas the effect has been known for a long time it is still a challenge to make the effect useful in everyday applications. [...]

Solid State and Template Free Synthesis of a Nanotubular Polyaniline-TiO2 Composite

Bonnot K., Grandcolas M., Keller V., Spitzer D., ISL-CNRS, FR
Our work report on the synthesis of a novel polyaniline-titania tubular composite at nanoscale. Significant new accomplishments relies on the synthesis of polyaniline-TiO2 composite nanotubes, as up to now most researchs in this field reported [...]

Nanocomposite Contact Material for MEMS Switches

Ding C., MacDonald N.C., university of california, santa barbara, US
This work reports the development of a nanostructured composite contact material for improving the contact reliability of MEMS switches. The nanocomposite material was integrated into a bulk titanium MEMS (BT-MEMS) switch which was fabricated using [...]

High-density polyethylene reinforced with titania nanoparticles

Bondioli F., Dorigato A., Fabbri P., Ferrari A.M., Messori M., Pegoretti A., Università di Modena e Reggio Emilia, IT
Titania nanoparticles were prepared by both hydrolysis of tetraethoxy titanium, in order to obtain a spherical shape, and by hydrothermal crystallisation. Nanoparticles were also surface modified with alkylsilanes in order to improve the compatibility with [...]
