Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Synthesis of tin disulphide (SnS2) and its characterization
    (CCSHAU, HISAR, 2022-07) Deepika Rani; Vinay Kumar
    The utilization of two dimensional materials in electronic and optical appliances is increasing day by day because of their excellent properties which can be utilized in various applications. The goal of the current study is to synthesize tin disulphide by low cost, wet chemical method at room temperature. To investigate its morphology, size, structure, and optical characteristics, different characterization techniques were used including FTIR, XRD, UV-Vis spectroscopy, PL spectroscopy, FESEM. FTIR spectra show Sn-S and S-S stretching vibrations which provide verification for the fabrication of SnS2. The band gap obtained from PL spectrum was found almost of the same order as obtained from UV-Vis spectrum. FESEM pictures represent the well-defined spherical morphology of the prepared SnS2. The XRD outcomes show the crystalline nature of the SnS2.
