TL;DR: In this article, the effect of nanofluids on convective heat transfer was investigated through a circular straight tube with a constant heat flux condition in the laminar and turbulent flow regime.

TL;DR: In this paper, various carbon-based particles such as graphite, carbon black, graphite nanofibers and carbon nanotubes were dispersed in mineral oil to systematically examine the effect of the size and shape of particles on the properties of friction performance.

TL;DR: In this article, the characteristics of NO production mechanisms in counter-flow flames with gasified coal syngas have been computationally studied through detailed chemical reactions and transport properties, and the NO production mechanism was analyzed in detail through the overall chemical reaction pathways.

TL;DR: In this paper, a one-step electrochemical method to produce water-based stable carbon nano colloid (CNC) without adding any surfactants at the room temperature was presented.

TL;DR: This study convincingly demonstrates that the large enhancements in the thermal conductivities of EG-based ZnO nanofluids tested are beyond the lower and upper bounds calculated using the models of the Maxwell and Nan et al. with and without the interfacial thermal resistance.
