two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...

This paper presents the optimization process in sol-gel technique to synthesize Titanium dioxide (TiO2) thin films using in-house Nano-TiO2 powder. Nano-TiO2 powder was previously synthesized in our lab from ilmenite which is a tin mining byproduct using a modified hydrothermal method. By varying the mass of Nano-TiO2 powder and acetic acid (catalyst) concentration in the sol-gel process, highl...

Objective(s): A remarkable growing effort has been conducted by several researchers to fabricate food packaging materials which are able to protect foodstuffs and enhance their shelf-life from food-borne pathogens and fungal attack which causes great damage to the food industries. Recent studies has focused on the potential applications of nano-metal oxides in food packaging area. Method...

To make predictions about the possible effects of nanomaterials across environments and taxa, toxicity testing must incorporate not only a variety of organisms and endpoints, but also an understanding of the mechanisms that underlie nanoparticle toxicity. Here, we report the results of a laboratory experiment in which we examined how titanium dioxide nanoparticles impact the population dynamics...

In this study, catalyst of rutile titanium dioxide nanoparticles (rTiO2-NP) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. To evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. The geometric...

Abstract: Reduction of the Titanium dioxide, TiO2, by methane was investigated in this work. The thermodynamic of reaction was examined and found favorable. The reaction of titanium dioxide with methane was carried out in the temperature range 1150°C to 1450°C at atmospheric pressure with industrial high porosity pellets prepared from titanium dioxide powder. The evolved gas analyzing method wa...

The acquisition of substantial dermal sealing determines the prognosis of percutaneous titanium-based medical devices or prostheses. A nano-topographic titanium surface with ordered nano-spikes and pores has been shown to induce periodontal-like connective tissue attachment and activate gingival fibroblastic functions. This in vitro study aimed to determine whether an alkali-heat (AH) treatment...
