The present work was targeted to design a surface against cell seeding and adhering of bacteria, Bacillus subtilis. A multi-walled carbon nanotube/titanium dioxide nano-power was produced via simple mixing of carbon nanotube and titanium dioxide nanoparticles during the sol-gel process followed by heat treatment. Successfully, quercetin was immobilized on the nanocomposite via physical adsorpti...

3,3,6,6-Tetramethyl-9-phenyl-3,4,6,7,9,10-hexahydroacridine-1,8-(2H,5H)-dione derivatives are synthesized by nano titanium dioxide as an efficient and reusable heterogeneous nano catalyst in a one pot multi component reaction. Easy preparation and separation of catalyst, simply workup procedure, clean reaction and reusability of the catalyst up to 7 times without appreciable loss of its catalyt...

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...

Paper presents results of study aimed the tin dioxide nanowire gas sensing performance improvement via in situ functionalization with NiO. Developed nanostructures have demonstrated improved by order gas sensitivity toward H2 and CO and drastic increase of selectivity to H2 against CO. Obtained results are discussed from the point of view of NiO/SnO2 heterojunction formation and its influence o...

Titanium dioxide has been proven for toxicity by in vitro and in vivo approaches, however, further studies are needed in nano-toxicological research using in silico analysis. In this study, Autodock 4.0.5 was used in an attempt to evaluate the interaction of titanium dioxide with proteins. Different cellular proteins were sorted to study the interaction, binding sites, and active sites as a poc...

Titanium Nitride (TiN) films were synthesized on AISI52100 bearing steel surface employing plasma immersion ion implantation and deposition (PIIID) technique. X-ray diffraction (XRD) proves that TiN phase exists in the surface layer. The depth profiles and chemical bonds were analyzed with X-ray photoelectron spectroscopy (XPS) combined with Ar ion etching. Atomic force microscope (AFM) reveals...

An ultrabroad absorber based on double-ring-shaped titanium nitride (TiN) nanoresonators, which can work in high temperatures, is proposed and numerically studied. The with some optimal parameters exhibits an averaged absorption of 94.6% the range 200 - 4000 nm (from ultraviolet to mid-infrared) a band from 3518 having > 90%. We have demonstrated detail physical mechanisms ultra-broad absorptio...

In the present study, 1.1 volume percent of nano size copper was incorporated into pure tin using hybrid microwave sintering assisted powder metallurgy route. Microwave sintered samples were extruded both at room temperature and at 230 °C. Microstructural characterization studies were conducted on the extruded samples to investigate the distribution characteristics of secondary phase and grain ...

Semiconductor sensors based on nanosized Pd-containing tin dioxide have been obtained by a sol-gel technique. Semiconductor gas-sensitive materials were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD) methods. Influence of Pd additives on sensitivity of the sensors to methane has been studied. Temperature dependences of electrical resistance in air and sensor...
