In this study, the mixed convection heat transfer in a mechanical ball bearing filled with nano-lubricants were investigated theoretically. our case, including eight balls revolving counter clockwise while inner shaft rotates direction and outer walls of kept at constant hot cold temperatures, respectively. Two kinds SiO2-water Alumina- Polyalphaolefin (PAO) different shapes nanoparticles consi...

Thirteen different cement-clinker crystalline phases present in the lime-silica-alumina system have been systematically modeled using a simple and general force field. This constitutes a new type of approach towards the study of lime-silica-alumina systems, where the simpler and more transferable Lennard-Jones potential was used instead of the more traditional Buckingham potential. The results ...

Through dip coating method monodisperse nickel nanoparticles assisted carbon membrane was prepared on porous alumina disc support. The solution by blending of thermally stable polymer polyphenylene oxide (PPO) and labile polyvinylpyrrolidone (PVP) followed addition nanoparticles. Size nanoparticles, surface porosity, average pore size, element composition optical properties the were investigate...

This paper reports on the synthesis and characterisation of polysulfone (PSf) ultrafltration (UF) membranes modifed with carbon coated alumina Ni-doped titanium dioxide (CCA/Ni-TiO2) nanoparticles. The syntheses of the membranes was carried out using the phase inversion process. The ...

In present day scenario, pesticides are widely used for pest control in agriculture, because of which, the drinking water sources (both surface and ground water) gets contaminated. Majority of the pesticides are defiant to biodegradation and are found to be carcinogenic in nature even at trace levels. Various conventional methods employed for removal of pesticide are surface adsorption, photo-c...
