MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008896 A) filed by National Institute Of Technology, Warangal, Telangana, on Jan. 29, for 'ultrasonically assisted eco-friendly method for synthesizing copper nanoparticles.'
Inventor(s) include Rajanikumar Kandikonda; Uday Kumar Khanapuram; Haranath Divi; and Rakesh Kumar Rajaboina.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an eco-friendly, cost-effective, and scalable method for synthesizing stable copper nanoparticles (Cu NPs) via a metal displacement reaction as shown in figure-1. The tartaric acid serves a dual function as a complexing agent for copper ions and a capping agent for the resulting nanoparticles, controlling nucleation and preventing aggregation. A copper-tartrate complex is prepared by mixing an aqueous copper salt solution with tartaric acid, followed by reduction using aluminum scrap as a sustainable reducing agent. Ultrasonic agitation is employed to enhance reaction kinetics, mass transport, and nanoparticle dispersion, yielding uniform, spherical to quasi-spherical Cu NPs with particle sizes of 20-50 nm. The nanoparticles exhibit high crystallinity, oxidation resistance, and long-term stability under ambient conditions. The synthesized Cu NPs are suitable for a wide range of applications, including wastewater treatment, catalysis, electronics, antimicrobial coatings, energy storage, biomedical, and agricultural uses, demonstrating versatility and industrial applicability without requiring toxic chemicals or inert atmospheres."
