Mixed matrix membranes (MMMs) were fabricated by incorporating synthesized titanium dioxide (TiO2) nanoparticles into polyether block amide (PEBA) matrix to fabricate TiO2/PBEA MMMs for CO2/N2 separation. The mesoporous channels of TiO2 increased the density of active sites with high accessibility and also facilitate the diffusion of CO2 in the gas separation process. Furthermore, amine groups ...

This study investigates the mechanism of photosensitization and the recombination of excited electron-hole pairs affected by depositing platinum (Pt) on the surface of titanium dioxide (TiO2). A new catalyst of Pt-TiO2 was prepared by a photoreduction process. Being model reactions, the photocatalytic oxidation of methylene blue (MB) and methyl orange (MO) in aqueous solutions using the Pt-TiO2...

Polyaniline (PANI) additives have been shown to have a significant effect on titanium dioxide (TiO2) nanoparticles as lithium ion battery anode materials. TiO2/PANI composites were prepared using a solid coating method with different ratios of PANI and then characterized using XRD and SEM. These composites have shown increased reversible capacity compared with pure TiO2. At the current rate of ...

A phase change memory (PCM) cell with atomic layer deposition titanium dioxide bottom heating layer is investigated. The crystalline titanium dioxide heating layer promotes the temperature rise in the AlSb3Te layer which causes the reduction in the reset voltage compared to a conventional phase change memory cell. The improvement in thermal efficiency of the PCM cell mainly originates from the ...

Production of titanium-dioxide nanomaterials (nano-TiO2) is increasing, leading to potential risks associated with unintended release of these materials into aquatic ecosystems. We investigated the acute effects of nano-TiO2 on metabolic activity and viability of algae and cyanobacteria using high-throughput screening. The responses of three diatoms (Surirella angusta, Cocconeis placentula, Ach...

Highly selective cellulose acetate (CA)/poly (vinyl alcohol) (PVA)/titanium dioxide (TiO2) imprinted membranes were synthesized by phase inversion and dip coating technique. The CA blend imprinted membrane was synthesized by phase inversion technique with CA as membrane matrix, polyethyleneimine (PEI) as the functional polymer, and the salicylic acid (SA) as the template molecule. The CA/PVA/Ti...

Titanium dioxide (TiO2) nanoparticles surface-modified by octadecyltrimethoxysilane (commercial name WD-11) are prepared via in situ surface-modification in dehydrated ethanol at room temperature. As-obtained TiO2 nanoparticles are characterized by means of Fourier transform infrared spectrometry, thermogravimetric, X-ray diffraction and transmission electron microscope. The tribological proper...

From 1916 to 2011, an estimated total of 165050000 metric tons of titanium dioxide (TiO2 ) pigment were produced worldwide. Current safety regulations on the usage of the TiO2 pigment as an inactive ingredient additive in human food are based on legislation from 1969 and are arguably outdated. This article compiles new research results to provide fresh data for potential risk reassessment. Howe...

OBJECTIVE There is a wide application of titanium dioxide (TiO2) nanoparticles (NPs) in industry. These particles are used in various products, and they also has biological effects on cells and organs through direct contact. MATERIALS AND METHODS In this experimental research, the effect of TiO2 on chondrogenesis of forelimb buds of mice embryos was assessed in in vivo condition. Concentratio...

Titanium dioxide (TiO2) nanofibres are a novel fibrous nanomaterial with increasing applications in a variety of fields. While the biological effects of TiO2 nanoparticles have been extensively studied, the toxicological characterization of TiO2 nanofibres is far from being complete. In this study, we evaluated the toxicity of commercially available anatase TiO2 nanofibres using TiO2 nanopartic...
