Q. Discuss the significance of 2D nanomaterials like borophene and graphene in advancing sustainable industrial technologies in India. (15 marks, 250-350 words)

Two-dimensional (2D) nanomaterials — atomically thin sheets such as carbon-based graphene and boron-based borophene — deliver large gains in surface area, strength and conductivity at minute doses. This "small input, large effect" property makes them a direct lever for India's transition to energy-efficient, low-emission industry.

Energy and material efficiency - Adding just 0.1 weight percent borophene to castor oil cut friction by about 42%, with better wear resistance and load-bearing capacity — demonstrated by IASST, Guwahati [1]. - The mechanism is a protective tribofilm of iron oxides, carbonaceous species and boron compounds that lowers shear stress and surface roughness [1]. Lower friction means lower industrial energy consumption and fewer associated emissions.

Greening industrial inputs - Castor oil is a renewable, biodegradable lubricant base; borophene disperses in it without chemical modification, avoiding toxic additive packages [1]. - This offers a substitute for petroleum-derived lubricants, aligning industry with India's climate and energy-conservation commitments.

Economic and strategic value - Reduced wear extends machinery lifespan and cuts maintenance costs in renewable energy systems, marine applications and manufacturing [1]. - Being the first demonstration of borophene as a lubricant additive — previously studied only for batteries, supercapacitors and fuel cells — it strengthens indigenous intellectual property in a frontier materials field [1].

Enabling research ecosystem - The work came from an autonomous institution under the Department of Science and Technology, IASST Guwahati (set up 1979) [2], showing that applied nanotechnology capacity now extends beyond metropolitan laboratories. - Support through the INSPIRE fellowship illustrates how research-talent schemes translate into publishable, application-oriented output [1].

2D nanomaterials thus link three national priorities — energy conservation, green manufacturing and self-reliance in advanced materials. The way forward lies in scaling laboratory results to industrial pilots, building cost-effective synthesis routes, and coupling such research with domestic feedstocks like castor. Sustained institutional support can convert these thin sheets into a broad-based foundation for sustainable industrialisation.
