The tribology of lubricated poly(ether ether ketone) (PEEK)—steel tribosystems was investigated in the static and boundary friction regime. Pentaerythrite ester and trimellitic acid ester were used as lubricants. The lubricants differed in their molecular structure but showed only minor differences in their rheological and cohesive energetic properties. In order to investigate the effect of the...

Recently, bio-based oil was used as industrial lubricant due to the increasing consideration on environment effect and health issues and in order to replace the usage of petroleum-based oil. The modified vegetable oil exhibit excellent lubrication and tribological performances when compared to the petroleum-based oil. In this study, the crude jatropha oil was modified via chemical modification ...

The long-term stability...

An understanding of the relationship between chemical structure and lubricant performance is highly desirable from both a fundamental and a practical perspective, such knowledge being vital to improve the performance of mineral oils and to guide the design of future synthetic lubricants. The rheological properties of alkanes of intermediate molecular size (C20–C40) are of particular interest as...

Inspired by the long-term effectiveness of living antifouling materials, we have developed a method for the self-replenishment of synthetic biofouling-release surfaces. These surfaces are created by either molding or directly embedding 3D vascular systems into polydimethylsiloxane (PDMS) and filling them with a silicone oil to generate a nontoxic oil-infused material. When replenished with sili...

The objective of this paper was to study the performance of household refrigerator having both air and water-cooled condenser, with 0.06% mass fraction CuO nanoparticle-lubricant mixture and different types of compressor oils. The experiment was done using HFC134a as the refrigerant, CuO nanoparticles, Polyol-ester oil (POE) oil which is used as the conventional lubricant in the household refri...

Depletion of mineral reservoirs along with health and environmental concerns have led to a greater focus on bio-lubricants. The purpose this study was analyze optimize the reaction conditions transesterification process for cotton biolubricant synthesis by using Response Surface Methodology (RSM). In RSM, Rotatable central composite design selected examine effect input factors yield bio-lubrica...
