Lumami - Researchers from Nagaland University in collaboration with University of Science and Technology, Beijing have developed a green and sustainable solution to protect metals from corrosion by using discarded apple leaves.

The research team converted apple leaf vase into carbon quantum dots, which acts as an eco-friendly corrosion inhibitor for copper. Laboratory tests showed that this method can provide up to 96.2% protection against corrosion, especially in acidic environments where metals are highly vulnerable. The study was led by Prof. Ambrish Singh from Nagaland University and Prof. Yujie Qiang from the University of Science and Technology,  Beijing. The findings suggest that these biomass-derived materials can form a stable protective layer on metal surfaces preventing, damage caused by corrosion.

The research has been published in the international peer-reviewed journal Journal of Alloys and Compounds, highlighting it's a scientific importance and global relevance.

Congratulating , the research team Prof.  Jagdish Kumar Patnaik, Vice-Chancellor of Nagaland University said the study demonstrate how agricultural waste can be transformed into high-value, environmentally friendly solutions. He added that such innovations reduce dependence on toxic chemicals and promote sustainable industrial practices. The researchers also noted that this technology has potential applications in sectors such as oil and gas, power generation, chemical processing and wastewater treatment. Apart from industrial benefits the study supports the concept of a circular economy by converting waste into useful materials and creating new opportunities for farming communities..

The international collaboration places Nagaland University at the forefront of sustainable material research and showcases its contribution to solving global environmental challenges.
