Guwahati: An worldwide joint analysis workforce of two universities from Nagaland and Beijing has discovered a method to use waste apple leaves to defend metals from corrosiResearchers from Nagaland University and the University of Science and Technology Beijing confirmed that carbon quantum dots derived from discarded apple leaves can present long-lasting, eco-friendly safety towards metal corrosion — a typical industrial downside.The India-China examine reported up to 96.2% corrosion safety for copper utilizing biomass-derived carbon quantum dots, presenting a sustainable various to typical, usually poisonous, corrosion inhibitors utilized in infrastructure and manufacturing.The collaborative examine was led by Prof. Ambrish Singh of Nagaland University and Prof. Yujie Qiang of the University of Science and Technology Beijing. The examine discovered that the newly developed apple-leaf carbon quantum dots (ACDs) can suppress copper corrosion in acidic environments with an inhibition effectivity of 94% at low concentrations, rising to 96.2% over longer publicity durations. The researchers mentioned these efficiency ranges are extremely promising for industrial purposes the place metals are routinely uncovered to harsh chemical situations.Prof. Singh, from the division of chemistry at Nagaland University and a visiting professor on the National University of Science and Technology Beijing, mentioned biomass-derived inhibitors like apple-leaf ACDs might lengthen the service lifetime of pipelines, storage tanks, and industrial gear whereas decreasing the environmental and well being hazards linked to typical chemical substances. He mentioned the tip purposes span a number of crucial sectors.“In industries such as oil and gas, chemical processing, power generation, and wastewater treatment, acidic environments accelerate corrosion, driving up maintenance costs and safety risks,” he added.Beyond industrial advantages, the examine additionally highlighted the worth of waste-to-wealth approaches by changing agricultural residue into high-value useful nanomaterials. University officers mentioned this analysis work helps round economic system fashions and will create earnings alternatives for farmers. The present outcomes are primarily based on laboratory-scale validation however the researchers are actually prepared to transfer in direction of pilot-scale testing and real-world deployment.Prof. Qiang of the National Centre for Materials Service Safety on the University of Science and Technology Beijing mentioned, “Using a green hydrothermal process, our research team converted apple leaves, an abundant agricultural waste, into nanoscale carbon particles doped with sulfur and nitrogen. These elements create multiple active sites that strongly adhere to metal surfaces. Electrochemical tests confirmed that the ACDs form a compact, stable protective film on copper, effectively blocking corrosive ion transfer.” “Advanced theoretical modelling further revealed that specific nitrogen-containing groups play a key role in anchoring the protective layer to the metal surface,” Qiang added.The findings have been not too long ago printed within the Journal of Alloys and Compounds, a number one peer-reviewed journal.Prof. Jagadish Kumar Patnaik, vice-chancellor of Nagaland University, mentioned, “Such innovations reinforce Nagaland University’s role in advancing green technologies for infrastructure and manufacturing sectors,” he mentioned.
