Recently, scientists from IASST, Guwahati, have demonstrated for the use of borophene, as a high-performance lubricant additive in castor oil.
Definition – Borophene is a two-dimensional (2D) nanomaterial composed of a single atomic layer of boron atoms.
Properties
High mechanical strength
Excellent thermal conductivity
High electrical conductivity
Superior chemical stability
Excellent load-bearing capability
Innovation – A minimal concentration of 0.1 wt.% borophene was incorporated into castor oil by the researchers.
The incorporation of the nano-additive resulted in a substantial improvement in lubrication performance, without necessitating chemical modification of the oil.
Mechanisms – During operation, borophene generates a protective tribofilm composed of the following components:
Iron oxides
Carbonaceous compounds
Boron-based compounds
Key Advantages
Energy Efficiency – Borophene-based bio-lubricants reduce energy losses associated with friction.
These lubricants contribute to improved operational efficiency in machinery.
Sustainability – They utilize renewable and biodegradable castor oil as a base component.
Their use reduces reliance on petroleum-based lubricants.
Equipment Protection – Borophene-based bio-lubricants minimize wear and surface degradation of mechanical components.
This protection extends the operational lifespan of machinery.
Environmental Benefits – Borophene-based bio-lubricants are environmentally friendly alternatives to conventional lubricants.
Their adoption supports sustainable manufacturing practices.
