    Study for the effect of size and shape on nanomaterials
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Joshi, Riya; Munish Kumar
    Nanomaterials had attracted researchers towards themselves because of their unique, intriguing, and promising features that differ from those of the bulk, nanoparticle systems are currently a fascinating area which has its application in wide range from medical field to agricultural field. High pressure applications of nanomaterials drew interest of reasearchers in this field. We have applied here Kumar EOS on nano and bulk materials to study their behavior. We have studied the pressure dependence of V/Vo and Bulk Modulus for various materials of different shapes and sizes for which experimental data was available. The materials used here are IF-WS2, NT-WS2, B12As2, Na2O, Pb, NaCl and LiF. Thus the present study reflects the sustainability and applicability of theory for nano as well as bulk materials as far as recent experimental information is concerned. Thus, it seems that we have a simple theory to study the different properties of nanomaterials depending on size and shape. The theory can also be used for bulk materials. We obtained the relation, which gives the size and shape dependence of θD , we computed the size dependence of θD for Co and Au. The results obtained are reported alongwith the available experimental data and comparision of present study with Qi Model is done which shows present study gives better agreement with the experimental data as compared with Qi Model. The size and shape dependence of θD for different nanomaterials viz. Au, Se, Co, Si, Al and Fe are reported.
