Thermal conductivity enhancement in MoO3–H2O nano-sheets based nano-fluids

This contribution reports on the thermal conductivity enhancement of MoO3–H2O nano-sheets based nano-fluid. The MoO3–H2O based nano-fluid consists of a set of 2D type nano-sheets with a basal size, approximately ranging from 108 × 200 nm2 to 415 × 631 nm2. A Higher Resolution Transmission Electron Microscopy (HRTEM) observation indicated that the nano-sheets consist of a collection of nano-crystallites (Ø∼7 nm) with various crystallographic orientations with 15 nm in average diameter. The Molybdenum is mainly in 6+ electronic valence. Their thermal conductivity measured via standard Pt wire exhibited an enhancement of about 36%.
