#Nanofluids: one #US_patent for every 240 papers in 2018! The high volume of theoretical and computational studies or low commercialization potential of nanofluids could be the reasons for the difference.
#Nanofluids are mainly used as coolant in #heat_transfer equipment, but novel applications include electromagnetic machines, electronic vehicles, data centers, fuel cells, and so on.
Among different nanomaterials, #diamond_nanoparticles have been widely used as #nanofluids for the enhancement of #heat_transfer.
During the past five years, #nanofluids have had the highest #annual_growth_rate of publications (more than 32%) among all #nanomaterials.
