[ 1 ] - Preparation and Characterisation of ZnO - SiO2 and Bi2O3 – CuO Nanocomposites
In the present work, ZnO - SiO2 and Bi2O3– CuO nanocomposites have been prepared by sol gel with alternate precursors existing in literature. They are characterised by XRD, SEM,UV, FTIR and photoluminescence spectra .The XRD results indicate a crystallite size of approximately 80 nm for both nanocomposites. SEM image shows a heterogeneous particle size for bot...
[ 2 ] - A report on the latest trends in nanofluid research
The term Nanofluids was first coined by Sir Stephen Choi in 1995 at Argonne National Laboratory ,U.S.A .Since the discovery, nanofluid have been explored as heat transfer fluids. Nanofluids increased the thermal conductivity of existing coolants (Water, Ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .From 1995 till 2008 nano...
[ 3 ] - Selection of nanofluid for heat transfer applications from existing models of thermal conductivity
Nanofluids are gaining much importance over the past decade due to their enhanced thermal conductivity, specific heat, cooling capacity, electrical conductivities. Novel properties of nanofluids are yet to be explored to the highest potential applications. One of the prominent applications of nanofluids is in thermal conduction. The presence of nanoparticle in a fluid can enhance the thermal co...
[ 4 ] - PREPARATION AND CHARACTERIZATION OF TiO2 Fe2O3 NANOCOMPOSITE BY SOL GEL METHOD
Nanocomposites have improved aspect ratio and better mechanical properties when compared to the composites which had structures less than 100nm They are 1000 times tougher compared to conventional composites. Besides mechanical properties, nanocomposites also have improved electrical conductivity, thermal stability, chemically resistant, flame retardant and low permeability. TiO2 finds its best...
