Flow and Heat Transfer of Single-and Two-Phase Boiling of Nanofluids in Microchannels
TL;DR: In this paper, high-speed video captured images of boiling two-phase flow through the transparent microchannel wall, where heat was provided electrically to the micro channel wall to bring about heating and phase change while recording temperature (via infrared camera) and channel pressure drop.

Anomalously increased effective thermal conductivities of ethylene glycol-based nanofluids containing copper nanoparticles
TL;DR: In this paper, it was shown that a "nanofluid" consisting of copper nanometer-sized particles dispersed in ethylene glycol has a much higher effective thermal conductivity than either pure or pure glycol or even polyethylene glycol containing the same volume fraction of dispersed oxide nanoparticles.
