Synthesis of charged chitosan nanoparticles as functional biolubricant

Colloids and Surfaces B: Biointerfaces, 2021
Osteoarthritis has been a major disease in recent years, which is mainly related to the breakdown of the lubrication function of the cartilage sliding interface, along with the inflammation of the joint capsule. In this paper, one kind of novel biomimetic nanoparticles (NPs) lubricant, named CS-PS, is synthesized through chemically grafting hydrophilic

Interfacial Water an Exceptional Biolubricant

Crystal Growth & Design, 2009
Interfacial water layers attract more and more attention in both material sciences and life sciences because of two characteristics that depend on the polarity of the surfaces involved: crystalline order and surface stability. Their interplay allows us to understand friction at the nanoscale under realistic conditions, including but not limited to the ...

Synthesis biolubricant from rubber seed oil

AIP Conference Proceedings, 2017
The objective was biolubricant preparation from rubber seed oil (RSO) using polymerization reactor with/without catalyst in batch reactor. Before become reactant in polymerization reaction, a non-edible rubber seed oil was converted into methyl ester by esterification/tranesterification reaction with methanol and acid/base catalyst.

Diesel biolubricants - synthesis and characterisation

2023
Over the past decade, regulations have been changed to reduce the environmental impact of diesel fuel reducing the content of sulphur and aromatics. This has resulted in a deterioration of low-temperature properties and lubricity. Also more attention has been given to renewability of the products to lessen the impact on the environment.

Production of Biolubricant From Castor Oil

SPE Nigeria Annual International Conference and Exhibition, 2017
Abstract In this research, bio-lubricant was produced from castor oil in two stage processes where methyl ester of the oil was produced by esterification and then transesterified using homogenous catalyst (NaOH). It was then blended with 15w/w% of Sodium Lauryl Sulphate (SLS) to produce bio-lubricant.

Synthesis of Branched Biolubricant Base Oil from Oleic Acid

ChemSusChem, 2020
AbstractThe mature manufacturing of synthetic lubricants (poly‐α‐olefins, PAO) proceeds through oligomerization, polymerization, and hydrogenation reactions of petrochemical ethylene. In this work, we utilize the inexpensive bio‐derived oleic acid as raw material to synthesize a crotch‐type C45 biolubricant base oil via a full‐carbon chain synthesis ...

Superior Biolubricant from a Species of Red Microalga

Langmuir, 2006
The rheological properties of the sulfated polysaccharide of the red microalga Porphyridium sp., a heteropolymer with a molecular weight of 3-5 x 10(6) Da, indicated that this material might be an excellent candidate for lubrication applications: the viscosity of the polysaccharide is stable over a range of temperatures, pH values, and salinities.

Rheology of Karanja (Pongamia) Oil Based Biolubricant

2017
Rheology is the science of flow and deformation of liquids and semi-solid materials under the effect of an applied force. Rheological characterization of lubricating oils is important to predict their flow behaviour in each stage starting from preparation to processing up to application.
