BACKGROUND The purpose of this study was to investigate the influences of nanoscale wear particles derived from titanium/titanium alloy-based implants on integration of bone. Here we report the potential impact of titanium oxide (TiO2) nanoparticles on adhesion, migration, proliferation, and differentiation of mesenchymal stem cells (MSC) from the cellular level to the molecular level in the Wi...
Environmental remediation of xenobiotic pollutants is an important issue in industrialized society. Catalyst-mediated pollutant photodegradation using solar light shows promising results. Titanium dioxide nanoparticles (TiO2 NPs) are a well-known standard for mineralizing organic water pollutants. Its use as sludge pointed out the need to support this photocatalyst ease both its and recovery. P...
Objective Titanium dioxide (TiO2) is a white pigment which is used in paints, plastics, etc. It is reported to induce oxidative stress and DNA damage. The N-acetylcysteine (NAC) was used to fight oxidative stress-induced damage in various tissues. The aim of this study was to evaluate the toxic effects of TiO2 nanoparticles by oral administration and the protective role of NAC on testes of a...
Titanium dioxide nanostructures are formed by a simple one-stage method of thermal oxidation titanium in the temperature range 700 - 900 °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 adv...
Strawberry (Fragaria × ananassa Dutch) is a widely grown fruit crop in the world due to its high aroma, taste, and nutritional value. In this study, the effect of foliar application of titanium dioxide nanoparticles on phytochemical modifications of strawberry cv. Sabrina under deficit fertigation conditions was investigated. The interaction effect of titanium dioxide nanoparticles (0, 6 and 12...
Titanium(IV) oxide graphene [1] or graphene oxide nano composite [2] were prepared by one-pot thermal hydrolysis of suspension graphene or graphene oxide nanosheets and titanium oxide in three different forms as a starting materials. Graphene nanosheets were produced in a large quantity from natural graphite using a high intensity cavitation field in a pressurized ultrasonic reactor [3]. The gr...
Several studies have been performed to understand the influence of titanium dioxide nanoparticles (TiO2-NPs) on cell function; however the effects of nanoparticle exposure on the plasma membrane have not been addressed so far. Since this interaction may alter cell metabolism and integrity, it is of importance to understand the modifications of the cell membrane, in particular of epithelial cell...
Multilayer coating structure comprising a copper (Cu) layer sandwiched between titanium dioxide (TiO2) were demonstrated as a transparent heat reflecting (THR) coating on glass for energy-saving window application. The main highlight is the utilization of Cu, a low-cost material, in-lieu of silver which is widely used in current commercial heat reflecting coating on glass. Color tunable transpa...
Nowadays, with the applications of titanium dioxide nanoparticles (TiO2-NPs) in pharmacy, food industry, cosmetics, toothpaste and sunscreens, pregnant women are exposed to nanoparticles. Since tooth development is vuln-erable to environmental impacts and mandibular first molar bud develops before maxillary first molar bud, in this ex-perimental study the effects of TiO2-NPs on the development ...
Titanium dioxide (TiO2) nanoparticles are currently the second most produced engineered nanomaterial in the world with vast usage in consumer products leading to recurrent human exposure. Animal studies indicate significant nanoparticle accumulation in the brain while cellular toxicity studies demonstrate negative effects on neuronal cell viability and function. However, the toxicological effec...
