In January 2026, researchers from Nagaland University developed carbon quantum dots from which agricultural waste to combat metal corrosion?

Researchers from Nagaland University and the University of Science and Technology Beijing developed eco-friendly carbon quantum dots to prevent metal corrosion.

The carbon quantum dots were synthesized from discarded apple leaves, an agricultural waste material.

The newly developed apple-leaf carbon quantum dots (ACDs) act as a sustainable alternative to toxic conventional corrosion inhibitors.

The ACDs demonstrated 94.0% corrosion inhibition efficiency for copper at low concentrations in acidic environments.

Corrosion protection efficiency improved to 96.2% with longer exposure duration, indicating long-term effectiveness.

The research specifically targets copper corrosion in acidic conditions, common in industrial settings.
