The Cover Feature illustrates the set-up of a closed bipolar cell for anodization titanium foils towards TiO2 nanotube layers. By using this kind set-up, two sides foil can be anodized simultaneously in different electrolytes. layers with identical or dimensions thus formed on both foil.

Nanoparticles synthesised by fungi have various applications and is much effective than the nanoparticles synthesised by other means. The present study is aimed to determine the antimicrobial potential of Titanium dioxide nanoparticles synthesised from the fungus, Aspergillus niger. The synthesised nanoparticles were characterised using UV spectrophotometer, SEM, and XRD. The antibacterial acti...

One of the major limitations during titanium (Ti) implant osseointegration is poor cellular interactions at biointerface. In present study, combined effect recombinant human Bone Morphogenetic Protein-2 (rhBMP-2) and nanopatterned Ti6Al4V fabricated with Directed irradiation synthesis (DIS) investigated in vitro. This environmentally-friendly plasma uses ions to create self-organized nanostruct...

Titanium dioxide is an emerging optical material, with a relatively high refractive index (n ∼ 2), which allows for high confinement of the electromagnetic field. Extensive research has been conducted on the negatively charged nitrogen vacancy centre in diamond due to its robust electronic and optical properties. In particular, its stable room-temperature photoluminescence properties have been ...

background and aims. incorporation of nano-particles to orthodontic bonding systems has been considered to prevent enamel demineralization around appliances. this study investigated cytotoxicity of transbond xt adhesive containing 1 wt% titanium dioxide (tio2) nano-particles. materials and methods. ten composite disks were prepared from each of the conventional and tio2-containg composites and ...

anionic dbs surfactant can be photodegraded in a tio2 dispersion and h2o2 solution under an hg-lamp (15 w) uv illumination or solar exposure. degradation process has been monitored through cleavage of aromatic moiety. degradation of the detergent was small when the photolysis was carried out in the absence of tio2 and h2o2 and it was negligible in the absence of light. most of the curves repres...

ag/tio2 photocatalytic nanoparticles by two methods, the sol – gel using a reducing agent and spattering was produced. crystalline phase of titanium dioxide was investigated in both. ag/tio2 peak in the sol – gel method at temperatures of 300,500 and 6000c were studied. ag/tio2 peak at different temperatures were determined using the spattering. xrd patterns of calcined this is tio2 and ag/ tio2.

in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...

The oxidation of alcohols to carbonyl compounds in a clean fashion (i.e., with water as a solvent or under solvent-free conditions, and using O2 or H2O2 as the primary oxidant) is the subject of considerable research efforts. A new approach for the selective oxidation of soluble aromatic alcohols in water under mild conditions via a novel composite photocatalyst has been developed. The catalyst...

Titanium and its alloys have superior electrochemical properties compared to other alloy systems due the formation of a protective TiO2 film on metal surfaces. The ability generate oxide layer will depend upon type be used. aim this work was characterize corrosion behavior titanium Ti-CP2 Ti-6Al-2Sn-4Zr-2Mo, Ti-6Al-4V, Ti Beta-C. Samples were anodized in 1 M H2SO4 H3PO4 solutions with current d...
