Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Study of gold ion irradiation induced effects on grapheme oxide/nickel ferrite nanocomposites
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Rawat, Pankaj Singh; Srivastava, R.C.
    In present work, the properties of graphite, graphene oxide (GO), reduced grapheme oxide (rGO), nickel ferrite (NiFe2O4) and GO/NiFe2O4 nanocomposites are investigated. The modifications induced by 100 MeV Au ion irradiation in ion fluence range of ~5×1011 ions/cm2 to 1×1013 ions/cm2 are studied. The samples GO and rGO were synthesized from graphite by modified Hummer’s method and NiFe2O4 was synthesized using PVP assisted auto-combustion method. The GO/NiFe2O4 nanocomposites were synthesized by ultrasonication mixing method. XRD, FESEM, TEM, FTIR, EDX, XAS, XPS, UV-Vis spectroscopy, Raman, VSM and EPR characterization techniques were employed to investigate various properties of pristine and irradiated samples. The multilayered less defective structure of graphite and few layered structures of GO and rGO were substantiated by XRD and Raman studies. Au ion irradiation increased the defect densities in graphitic layers of all samples. It is found that ion irradiation lead to the removal of oxygen functionalities and increased graphitization in GO in a controlled manner. However, in contrast to GO, the relative oxygen functionalities of graphite and rGO showed an increment upon Au ion irradiation. This suggests that the microstructure and abundance of oxygen functionalities played a dominant role in deciding the behaviour of graphene based samples towards irradiation. Homogeneous distribution of NiFe2O4 in GO matrix was observed in FESEM. A decrease in saturation magnetization of composite in comparison to NiFe2O4 was due to the presence of nonmagnetic GO layers. The NiFe2O4 system remained in the spinel phase in composite form even after irradiation. The structural properties and optical band gap of irradiated NiFe2O4 and GO/NiFe2O4 samples were not changed appreciably after irradiation. The phase stability of NiFe2O4 in irradiated composite was also verified by XPS investigation. Saturation magnetization of both NiFe2O4 and composite samples decreased after irradiation, while coercivity and remnant magnetization showed slight increment. The decrease in g-value and EPR line width upon irradiation in NiFe2O4 samples was attributed to increased intraparticle super-exchange interactions. The minute changes in different properties of NiFe2O4 and composite samples may be due to the creation of defects and small variations in structural parameters with the irradiation. Results suggest that the GO based materials are sensitive towards SHI irradiation while NiFe2O4 shows appreciable resistance towards Au ion irradiation upto 1x1013 ions/cm2.
