MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611001952 A) filed by Swami Rama Himalayan University, Dehradun, Uttarakhand, on Jan. 8, for 'method for the green synthesis of aluminium nanoparticles from scrap materials utilizing citrus peel extract.'
Inventor(s) include Dr. Archna Dhasmana; Ayushi Santhanam; and Dr. Sanjay Gupta.
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 invention relates to a green synthesis method in the field of nanomaterials, where aluminium nanoparticles are produced from scrap materials employing citrus peel extract as both reducing and capping agent. The process involves preparing an aqueous citrus peel extract by cleaning, drying, and grinding citrus peels, followed by extracting bioactive phytochemicals under heating conditions. Scrap aluminium is processed into an aluminium precursor solution, which is then combined with the extract in a reaction vessel equipped with a heating element, stirring mechanism, and pH sensing means. The mixture is maintained at 82 C to 88 C and a pH of 6.5 to 7.0 for 6 to 8 hours to yield a colloidally stable nanoparticle suspension. Subsequent high-speed centrifugation and drying yield a fine nanoparticle powder with uniform size distribution, characterized by a UV-visible absorption peak at approximately 225 nm."
