The low thermal conductivity of fluids used in many industrial applications is one of the primary limitations in the development of more efficient heat transfer systems. A promising solution to this problem is the suspension of nanoparticles with high thermal conductivities in a base fluid. These suspensions, known as nanofluids, have great potential for enhancing heat transfer. The heat transf...

A review of the authors’ research works on Variable-Angle Spectroscopy (VASE) graphene-based films is presented. The interaction graphene oxide (GO) with magnetron-sputtered metals a promising area. VASE optical models GO thin deposited titanium (Ti), silver (Ag) and gold (Au) are discussed. Moreover, properties nanoplatelet (GNPS) reduced (RGO) stabilized Poly(Sodium 4-Styrenesulfonate) (PSS) ...

Collagen microfibrils biomimetically intercalate graphitic structures in aqueous media to form graphene nanoplatelet-collagen complexes (G-Cl). Synthesized G-Cl-based stable, aqueous bionanocolloids exhibit anomalously augmented charge transportation capabilities oversimple collagen or graphene based colloids. The concentration tunable electrical transport properties of synthesized aqueous G-Cl...

Morphological and chemical transformations in boron nitride nanotubes under high temperature atmospheric conditions is probed in this study. We report atmospheric oxygen induced cleavage of boron nitride nanotubes at temperatures exceeding 750 °C for the first time. Unzipping is then followed by coalescence of these densely clustered multiple uncurled ribbons to form stacks of 2D sheets. FTIR a...

The tribological behaviour of diamond-like carbon (DLC) and graphene nanoplatelets (GNP) nanocomposite has not been previously explored in a lubricated environment, with some previous studies reporting only on materials the surface DLC. In this study DLC-GNP films various GNP coverages were synthesised by 3 step process: spin coating suspension, heat treatment, DLC deposition. study, effect cov...
