in the present study, the interaction between nano-tio2 and lysozyme was investigated by the method of uv-vis detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-tio2 over the temperature range (293-373) k in different buffer and ph, using temperature scanning spectroscopy. the presence of nano-tio2 ...

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...

The influences of nano-ZrO2 (NZ), nano-TiO2 (NT), nano-Fe2O3 (NF) and nano-Al2O3 (NA) additions on properties of the fresh and hardened cement paste in comparison with the fine cement paste were experimentally studied. Mini slump and flow cone tests were conducted on fresh cement pastes. Moreover the compressive and tensile strength of hardened cement paste were measured. SEM micrographs and XR...

Recently nano-materials are widely used but they have shown contrasting effects on human and plant life. Keeping in view the contrasting results, the present study has evaluated plant growth response, antioxidant system activity and photosynthetic apparatus physiological and ultrastructural changes in Brassica napus L. plants grown under a wide range (0, 500, 2500, 4000 mg/l) of nano-TiO2 in a ...

Titanium dioxide (TiO2) micro and nano architectures have been intensively studied in 15 the past years because of many varied applications in environmental, energy conversion, and 16 storage fields, such as heterogeneous catalysis, dye-sensitized solar cells, lithium/sodium ion 17 batteries, lithium-sulfur (Li-S) batteries, and bio-nanotechnology, etc. Especially the surface and 18 interface s...

BACKGROUND Oral cavity is a doorway for a variety of products containing titanium dioxide (TiO2 ) nanoparticles (NPs) (nano-TiO2 ) such as food additives, oral healthcare products and dental materials. Their potential to penetrate and affect normal human oral mucosa is not yet determined. OBJECTIVES To evaluate the ability of nano-TiO2 to penetrate the in vitro reconstructed normal human bucc...

Assisted by the aerosol co-deposition approach, Prussian blue (PB)-TiO2 composite film can be in-situ formed in one step. The architecture of this film is constructed by two layers: PB-TiO2 nano-particles as a ground layer and individual PB micro-cubes as a top layer. Together with the strong electrocatalytic ability from regular PB morphology, TiO2 can denote its high catalysis in H2O2 detecti...

Titanium dioxide (TiO2) (nano)particles are produced in large quantities and their potential impacts on ecosystems warrants investigations into fate after disposal. TiO2 particles released wastewater retained by treatment plants accumulate digested sludge, which is increasingly incinerated industrialized countries. Therefore, we investigated the changes of Ti-speciation during incineration as-r...

asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...
