Background and Context
The Problem
Friction and wear are among the major causes of energy loss and equipment failure in industrial machinery worldwide. This leads to:
- Significant energy wastage
- Frequent machinery breakdowns
- High maintenance costs
- Reduced equipment lifespan
Why Castor Oil?
- Renewable resource
- Biodegradable
- Environmentally friendly
- However, limited performance without additives
What is Borophene?
- Two-dimensional (2D) nanomaterial composed entirely of boron atoms
- Possesses high mechanical strength
- Exhibits excellent electrical conductivity
- Previously studied for:
- Batteries
- Supercapacitors
- Fuel cells
Mechanism of Action
The borophene additive works through the following mechanism:
