low carbon steel samples were both shot into and inoculated with titanium in order to improve mechanical properties such as strength and toughness. sem observations and x-ray analyses revealed that titanium nitride and titanium carbonitride precipitates being scattered in the ferrite substrate reduce the grain size in all as-cast, heat-treated and as-rolled cases. the growth of the grains at hi...

This photocatalytic conversion of carbon dioxide laboratory experiment is designed for an advanced undergraduate chemistry or chemical engineering majors laboratory course. It introduces the science of emerging sustainable energy technologies through hands-on experimentation. By photo-irradiating a glass flask containing water, catalyst, and carbon dioxide, students explore the potential of new...

Porous titanium carbide (TiC) and TiC/Ti composites were synthesized by self-propagating high-temperature synthesis (SHS). Titanium and carbon powders were blended by various Ti/C blending ratios. The heat of reaction between titanium and carbon was high enough to induce the self-sustaining reaction of TiC formation on condition that some processing parameters (Ti/C ratio and porosity of the pr...

in this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (tio2). the tio2nanoparticles was characterized by scanning electron microscopy (sem), x-ray diffraction (xrd) and bet technique.the tio2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6h-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite electrode. the resulting modified el...

Strong adsorption of pollutants on activated carbon may inhibit their diffusion to the catalyst on the surface of the adsorbent and hence reduce he whole photocatalytic process. Oxidation of the carbon surface will change the adsorption properties of the carbon; and increase the capability of arbon surface to carry more titanium dioxide. In this work, activated carbon was oxidized with differen...

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...

The aim of the article is to present recent developments in material research with bisphenyl-polymer/carbon-fiber-reinforced composite that have produced highly influential results toward improving upon current titanium bone implant clinical osseointegration success. Titanium is now the standard intra-oral tooth root/bone implant material with biocompatible interface relationships that confer p...

Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...
