“…Since this time, many papers concerning nanofluids have been published and their number increase from year to year. Carbon-based material as new type of nanomaterials including multiwalled carbon nanotubes [2,3], nanofibers [4], graphene [2,5] or fullerenes [6,7,8] are largely considered. Also, more regular and traditional materials, such as metals [9] or oxides [10], are used in the preparation of nanofluids and show interesting thermophysical properties.…”
