Cooling is one of the most important challenges in industries, especially in the automotive industry. The coolant which is used in engine radiators possesses lower thermal conductivity. To enhance the thermal properties, coolant was dispersed in nano-sized particles and the fluid is called as Nanofluid. In this Study, Silica Nanoparticle was dispersed in Paraflu Engine coolant usin...

Nanomaterials tend to agglomerate in aqueous media, resulting in inaccurate safety assessment of the biological response to these substances. The present study searched for suitable dispersion methods for the preparation of nanomaterial suspensions. Titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles were dispersed in a biocompatible dispersion medium by direct probe-type sonicator and i...

Realizing the efficacy of liquid-phase exfoliation technique to obtain a greater quantity graphene, this study demonstrates cost-effective bio-surfactant-assisted few-layer graphene (FLG) with low defect ratio. An ultrasonic bath without any toxic chemicals or chemical modification was employed exfoliate at room temperature. Several state-of-the-art characterization techniques such as TEM, AFM,...

This paper presents an investigation of the effect graphene nanoparticles on mechanical properties glass fiber reinforced epoxy composite. The composites were fabricated using vacuum infusing molding. Dispersion nanoplatelets was done bath sonicator and stirring. physical examined according to ASTM standards. Results showed that there a significant improvement in tensile flexural by addition 0....

The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. It can also recombine to form hydrogen peroxide which is very useful in water treatment. In this study, terephthalic acid (TA) and potassium iodide dosimetry were used to quantify and inve...

Benzyl alcohol used as the sample preparation solvent in the determination of residual solvents in pharmaceutical bulks yielded benzene, toluene, and benzaldehyde on capillary gas chromatography (GC) by sonication. The factors responsible for compounds generated are discussed. The quality of benzyl alcohol and the type of sonicator were not involved in the generation of benzene, toluene, and be...

The purpose of this experimental study is to evaluate the effects of particle species, surface charge, concentration, preparation technique, and base fluid on thermal transport capability of nanoparticle suspensions (nanofluids). The surface charge was varied by changing the pH value of the fluids. The alumina (Al2O3) and copper oxide (CuO) nanoparticles were dispersed in deionized (DI) water a...
