The use of mineral lubricants has been demonstrated to be detrimental to the environment. Consequently, there has been a shift toward the utilization of biodegradable lubricants, such as those derived from vegetable sources. The last ones necessitate the incorporation of additives to …

• Novel GO-N-DDP nanosheets were synthesized from GO. • Modified GO-N-DDP nanosheets showed good stability in PAO6. • 0.05 wt% GO-N-DDP nanolubricant showed great friction performance (25 % reduction). • 0.10 wt% GO-N-DDP nanolubricant showed the greatest antiwear behavior. • Tribofilm formation …

The aim of the present research is to analyze thermophysical and tribological properties of PAO4 nanolubricants containing functionalized (GO-polyethyleneimine-oleic acid, GO-PEI-OA) and non-functionalized (GO) graphene oxide. Nanodispersions of these NPs were prepared, observing a better stability for the GO-PEI-OA nanolubricants. As for …

In the last few years we have observed a breakpoint in the development of graphene-derived technologies, such as liquid phase filtering and their application to electronics. In most of these cases, they imply exposure of the material to solvents and ambient moisture, …

Abstract Triangulenes are a class of open‐shell triangular graphene flakes with total spin increasing with their size. In the last years, on‐surface‐synthesis strategies have permitted fabricating and engineering triangulenes of various sizes and structures with atomic precision. However, direct proof of the …
