Synthesis, characterisation and thermo-physical investigations on magnesia nanoparticles dispersed in ethylene glycol–DI water (50:50)

In the present work, magnesia nanoparticles (17 nm) were synthesised by solution combustion and characterised using X-ray diffraction and scanning electron microscopy. Nanofluid prepared by magnesia dispersion in ethylene glycol and deionised water (50:50) is characterised using Fourier transform in...
