Solution Grown Nanostructured Ceramic Coatings for Photocatalytic and Antibacterial Surface

Tao T., Cho J., Binghamton University, US

Ceramics coatings have received great attention for use as a functional surface, as well as a protective and barrier coating. We report a low-temperature hydrothermal processing of nanostructured ceramic coatings that enable their surface to [...]

Titanate TiO2 Nanowire Bio-Scaffold as a Novel Sensor for Cancer Cell Differentiation

Alismail H., University of Arkansas, US

Human body cells undergo continuous division to compensate the cell loss in the body. This process is highly regulated and any abnormality can cause Cancer, which is a hot topic nowadays. Indeed, Cancer cell research [...]

A Combined Photoelectrochemical and Theoretical Study to Understand Adsorption Properties of Organic Molecules on TiO2 Surfaces

Sun T., Yunnan University, CN

Titanium dioxide (TiO2) applications in clean energy generation and environmental remediation involve interactions between organic species and TiO2 materials. Such interactions not only depend on the intrinsic properties of TiO2, but also on its surfaces [...]

Roll-to-roll application of photocatalytic TiO2 nanoparticles for printed functionality

Saarinen J.J., Valtakari D., Bollström R., Stepien M., Haapanen J., Mäkelä J.M., Toivakka M., Abo Akademi University, FI

We present here ultraviolet A (UVA) light controlled photocatalytic activity of roll-to-roll (R2R) deposited TiO2 nanoparticles on paper, board, and plastic films both for controlled wetting and oxygen sensors for modified atmosphere packages (MAPs). It [...]

Comparing Biocompatibility of Titanium Orthopaedic Implants With and Without an Ultra-thin Coating of TiO2 by Ion Beam Assisted Deposition

Miralami R., Namavar F., Thiele G.M., Sharp J.G., Garvin K.L., University of Nebraska Medical Center, US

Introduction: Annually, more than one million Americans undergo arthroplastic surgeries, and by 2030 the projected number will exceed more than four million [1]. Thus, there is a serious need to accommodate such overload. It has [...]

Immobilization of TiO2 nanopowders in multilayer fluorinated coatings for highly efficient clear and turbid wastewater remediation

Diamanti M.V., Bettini L.G., Milani P., Sansotera M., Persico F., Navarrini W., Pedeferri M.P., Politecnico di Milano, IT

The use of nanosized photocatalytic TiO2 in suspension or slurry type reactors is well reported. However, the industrial feasibility of such systems is limited, on account of the low quantum efficiency reported for slurry processes [...]

Photocatalytic activity of commercial TiO2 oxides in the oxidation reaction of nitric oxide

Luévano-Hipólito E., Martínez-de la Cruz A., López-Gallegos V.M., Garza-del Bosque H., Universidad Autonoma de Nuevo Leon, MX

In this work will be explored the potential application of six commercial titanium oxides with different crystalline structures to act as an efficient photocatalyst in the conversion reaction of NOx gases to innocuous products as [...]

Catalytic oxidation of carbon using TiO2 based nanoparticles prepared using flame synthesis

Memon N.K., Ismail M.A., Anjum D.H., Chung S.H., Qatar Environment and Energy Research Institute, QA

Titanium dioxide (TiO2) nanoparticles are used in numerous applications involving catalysis, photo-catalysis, water purification, electrode for Li-ion batteries, polymer fillers, and pigments. Multiple-diffusion flames are used to coat/dope the TiO2 nanoparticles with various elements such [...]

Nanoaerosol release characteristics of wallpaper coated with TiO2 nanoparticles in an air-jet simulated test chamber

Bae G.N., Park S.H., Lee S.B., Kim J.B., Korea Institute of Science and Technology, KR

Consumer nanoproducts are interested in public health aspects. In Korea, wallpaper is a popular construction material of housing. Wallpaper is well known to emit various volatile organic compounds and carbonyl compounds. Some wallpaper is coated [...]

Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]
