Ni-coated single-walled carbon nanotubes (SWNTs) were dispersed in four fluids (of varying viscosities) to create four different nanofluids. Due to the magnetic properties of the coated nanotubes the researchers induced a magnetic field to increase the thermal conductivity of the nanofluids. The increase in thermal conductivity was due to the alignment of the carbon nanotubes into chains due to the magnetic field. A Thermal Constants Analyzer was used to measure ...
High speed microscopy was used to allow real time visualization of the movement of nanoparticles made up of single-walled carbon nanotubes (SWCNT) and Fe2O3. An electrostatic force was induced to the nanotube/Fe2O3 composite and caused perfect conjugate structures which result in excellent thermal, electrical, and mechanical properties. The alignment of the carbon nanotubes in nanosuspensions may offer new opportunities for the development of nanofluids....
