The mechanism of lime dissolution in steelmaking slag and the factors that influence rate are highly significant improving efficiency process; however, they yet to be fully understood. Here, effects Al2O3/TiO2/Na2O additives on composition molten were investigated using a rotating cylinder technique. results indicate promotion coefficients at 1400 °C decrease order Na2O > TiO2 Al2O3. Further...

This study investigates the prediction model of compressive strength of self–compacting concrete (SCC) by utilizing soft computing techniques. The techniques consist of adaptive neuro–based fuzzy inference system (ANFIS), artificial neural network (ANN) and the hybrid of particle swarm optimization with passive congregation (PSOPC) and ANFIS called PSOPC–ANFIS. Their perf...

Titanium(IV) oxide graphene [1] or graphene oxide nano composite [2] were prepared by one-pot thermal hydrolysis of suspension graphene or graphene oxide nanosheets and titanium oxide in three different forms as a starting materials. Graphene nanosheets were produced in a large quantity from natural graphite using a high intensity cavitation field in a pressurized ultrasonic reactor [3]. The gr...

Metal oxide nanoparticles are used in a broad range of industrial processes and workers may be exposed to aerosols of the particles both during production and handling. Despite the widespread use of these particles, relatively few studies have been performed to investigate the toxicological effects in the airways following inhalation. In the present study, the acute (24 h) and persistent (13 we...

Two types of ceramic-polymer composite thick films were deposited on Cu substrates by an aerosol deposition process, and their properties were investigated to fabricate optimized ceramic-based polymer composite thick films for application onto integrated substrates with the advantage of plasticity. When polymers with different mechanical properties, such as polyimide (PI) and poly(methyl methac...

The oxidation crack healing of Cr2AlC and Cr2(Al,Si)C was studied and compared with known healing of Ti2AlC. The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides -Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only -Al2O3 is formed, but full crack healing is relatively slow. The efficiency o...

we report on the synthesis, morphology, chemically and structurally of tio2-nio-sio2 nanostructure. the tio2-nio-sio2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. the coatings were deposited on dried soda-lime glass slides by spin coating. composite powders and coating on glass have been characterized by xrd, sem, edax, and ...

In present work a experimental study based on thermosyphon is investigated using a solid nano-particles added to water as a working fluid. Tests are made on a thermosyphon. The experiment was performed in order to measure the temperature distribution and compare the heat transfer rate of the thermosyphon with the nano uid and with pure water. The tested concentration level of the nano-particles...

Bismuth vanadate and titanium dioxide (BiVO4/TiO2) composites, used as visible-light-driven photocatalysts were successfully synthesized with different mole ratios by coupling of a co-precipitation method with a sol-gel method. The phase transitions of the as-prepared BiVO4/TiO2 composites were carried out by X-ray diffraction (XRD). The results clearly indicated that the as-synthesized BiVO4/T...

Engineered aluminum oxide (Al2O3), titanium dioxide (TiO2), and silicon dioxide (SiO2) nanoparticles (NPs) are utilized in a broad range of applications; causing noticeable quantities of these materials to be released into the environment. Issues of how and where these particles are distributed into the subsurface aquatic environment remain as major challenges for those in environmental enginee...
