Dr. Rohit Ranjan Shahi from the Department of Physics of Central University of South Bihar (CUSB) has filed an Indian patent at Kolkata Patent Office for his latest innovation on the development of High Entropy Alloys Target and Thin Fims along with his research scholar Priyanka Kumari. The patent, titled “Target Preparation of High Entropy Alloys for Thin Film Deposition and Method thereof”, is an Indian patent from the department of Physics of CUSB published in official journal of the patent office. CUSB Vice-Chancellor Prof. Kameshwar Nath Singh, Registrar Prof. Narendra Kumar Rana, Prof. Budhendra Singh, Head, Physics, Dean SPCS Prof. Atul Pratap Singh congratulated to Dr. Shahi and Priyanka for their advance cutting edge research in the area of Quantum materials that will also fulfil the mission and vison of National Quantum Mission of Government of India. CUSB Vice-Chancellor Prof. Kameshwar Nath Singh said that through this research CUSB will also contributing for the global research in the area of QUAUTUM Materials.

The patent was filed on 19th January 2026 and after initial examination and novelty of the patent It has now been published in the Patent Office Journal with issue no. 05/2026 on 30th January, 2026. Dr. Shahi, group leader and Patent Investigator (PI) said that commercial availability of High Entropy Alloy targets with precise composition is limited, but the developed target demonstrates superior homogeneity and enables the precise synthesis of thin films, marking a step forward in the design and application of advanced magnetic and non-magnetic materials. For the synthesis of different thin films the targets are brought from China or from other country. Further he said the developed materials and its method will be useful for overcoming critical bottlenecks in large-scale industrial applications and contribute to the make in India initiative of the government of India. This innovation is expected to improve efficiency, reduce costs, enhance performance, and facilitate the development of magnetic and non-magnetic HEA thin films which can also be used as an essential component for future technological devices. The innovation is helpful for the design and development of novel HEA advanced Quantum materials which will accelerate the Quantum mission of government of India.
