Carbon Nanotori Structures for Thermal Transport Applications on Lubricants.

Carbon nanostructures have been recently applied to improve industrial manufacturing processes and other materials; such is the case for lubricants used in the metal-mechanic industry. Nanotori are toroidal carbon nanostructures, obtained from chemical treatment of multi-wall carbon nanotubes (MWCNTs). This material has been shown to have superb anti-wear and friction reduction performance, having the ability to homogeneously disperse within water in concentrations between 1-2 wt.

Thermal Conductivity Performance of 2D hBN/MoS/Hybrid Nanostructures Used on Natural and Synthetic Esters.

In this paper, the thermal conductivity behavior of synthetic and natural esters reinforced with 2D nanostructures-single hexagonal boron nitride (h-BN), single molybdenum disulfide (MoS), and hybrid h-BN/MOS-were studied and compared to each other. As a basis for the synthesis of nanofluids, three biodegradable insulating lubricants were used: FR3 and VG-100 were used as natural esters and MIDEL 7131 as a synthetic ester. Two-dimensional nanosheets of h-BN, MoS and their hybrid nanofillers (50/50 ratio percent) were incorporated into matrix lubricants without surfactants or additives.
