Titanium implants have a thin oxide surface layer. The properties of this oxide layer may explain the good biocompatibility of titanium implants. Anodic oxidation results in a thickening of the oxide film, with possible improved biocompatability of anodized implants. The aim of the present study was twofold: (1) firstly, to characterize the growth behaviour of galvanostatically prepared anodic ...

Titanium is a highly reactive metal so that a thin layer of oxide forms on its surface whenever exposed to the air or other environments containing oxygen. This layer increases the corrosion resistance of titanium. The oxide film is electrochemically formed through anodizing. In this study, anodizing of titanium was performed in phosphate-base solutions such as H3Po4, NaH2Po4, and Na2Hpo4 at 9....

Density functional theory calculations were carried out to study the interaction of heroin molecule with pristine and N-dopedTiO2 anatase nanoparticles. The oxygen atom of heroin molecule was found to be the binding site on the heroin molecule. In contrast, the binding site of TiO2 nanoparticle was positioned over the fivefold coordinated titanium atoms. The results showed that the adsorption e...

objective(s):  titanium oxides are known to be appropriate hemocompatible materials which are suggested as coatings for blood-contacting devices. little is known about the influence of nanometric crystal structure, layer thickness, and semiconducting characteristics of tio2 on blood hemostasis.   materials and methods: having used sol-gel dip coating method in this study, tio2 thin films were d...

Synthesis of different kinds of nanotubes were considering after the discovery of carbon nanotubes . Lately has been noticed synthesis of vanadium oxide nanotubes. Vanadium oxide nanotubes are made of multilayer scrolls with thick walls built up from several vanadium oxide layers. This compunds be used as catalysts, molecular sieves, absorbents and energy storage devices. In this research study...

Most widely affecting species include Culex quinquefasciatus, A. albopictus and aegypti which serve as vectors for many hematophagous diseases. Various control measures have been used to the mosquitoes but most important is use of synthetic insecticides. This research focused on botanical extracts green synthesized silver nanoparticles four different plants i.e. Moringa Olifera, Zingiber offici...

The application of implants for dental and orthopedic surgery has increased rapidly within the past few decades. In craniomaxillofacial surgery, different implant systems have been applied, for example, for dental and bone replacement or osteosynthesis plates and screws. These implants may be made of pure titanium or a titanium alloy, usually titanium-aluminumvanadium (Ti-6Al-4V). The surface c...

Aggregation of metal oxide nanoparticles in aqueous media complicates interpretation of in vitro studies of nanoparticle-cell interactions. We used dynamic light scattering to investigate the aggregation dynamics of iron oxide and zinc oxide nanoparticles. Our results show that iron oxide particles aggregate more readily than zinc oxide particles. Pretreatment with serum stabilises iron oxide a...
