Tribological Study of Functional Fluids Based on Castor Oil

open access: yesASM Science Journal, 2022
Vegetable oil-based lubricants are environment-friendly options as against conventional lubricants. This paper discusses the synthesis as well as characterisation of esters from ricinoleic acid and sebacic acid whose main source is castor oil ...

Technical Performance and Chemical–Physical Property Assessment of Safflower Oil Tested in an Experimental Hydraulic Test Rig

open access: yesLubricants, 2023
Safflower (Carthamus tinctorius L.) is an underestimated and multipurpose crop resistant to environmental stresses. Its oil presents useful chemical–physical properties, potentially exploitable for industrial purposes as a bio-based lubricant.

On the kinetic and allosteric regulatory properties of the ADP-glucose pyrophosphorylase from Rhodococcus jostii: An approach to evaluate glycogen metabolism in oleaginous bacteria [PDF]

open access: yes, 2016
Rhodococcus spp. are oleaginous bacteria that accumulate glycogen during exponential growth. Despite the importance of these microorganisms in biotechnology, little is known about the regulation of carbon and energy storage, mainly the relationship ...

Evaluation of the lubricating power of chemical modified Sesame oil additivated with Cu and Al2O3 nanoparticles

open access: yesDyna, 2018
Biolubricant from modified sesame oil (Sesamumindicum L.) was produced. The lubricant base consists of a mixture in a volume ratio of 74 parts of epoxidized sesame and 26 parts of transesterified sesame oil.

An Environmentally Friendly Nb–P–Si Solid Catalyst for Acid-Demanding Reactions [PDF]

open access: yes, 2017
Here, we report the structural characteristics, the surface properties, and the catalytic performances of a Nb–P–Si ternary oxide material (2.5Nb2O5·2.5P2O5·95SiO2, 2.5NbP) in two reactions of importance for biomass valorisation and green industrial ...

Data set for determination of lubrication film thickness and lubrication state between bone and Ti–6Al–4V interface under three biolubrications

open access: yesData in Brief, 2019
The lubrication states between the friction pairs in lubrications have an important effect on its tribological behavior. Therefore, the aim of this complementary data article is to identify the corresponding lubrication states between bone and Ti–6Al–4V ...

Process Optimization of the Transesterification Processes of Palm Kernel and Soybean Oils for Lube Oil Synthesis [PDF]

open access: yes, 2017
Palm kernel and soybean oils were used as raw materials to produce lube oils. Their transesterification/conversion processes were investigated for different catalyst-oil concentrations.

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Friction and wear phenomena of vegetable oil based lubricants with additives at severe sliding wear conditions [PDF]

open access: yes, 2017
The tribological responses of palm oil and soybean oil, combined with two commercial antiwear additives (zinc dialkyl dithiophosphate and boron compound), were investigated at a lubricant temperature of 100 °C and under severe contact conditions in a ...
