  • Heartiest congratulations to my Ph.D. student, Manish Kumar Mohanta on being conferred the prestigious ‘Karnataka DST Nanoscience Fellowship Award’ consisting of a cash prize of Rs. 50,000/- and a certificate at the Bengaluru India Nano 2022.

  • Our article entitled ‘Group-IV (A) Janus dichalcogenide monolayers and their interfaces straddle gigantic shear and in-plane piezoelectricity’, published in Nanoscale 13 (2021) 5460-5478 has been featured as the themed collection of the Nanoscale most popular 2021 Articles.

  • Our article titled 'Superhigh out-of-plane piezoelectricity, low thermal conductivity and photocatalytic abilities in ultrathin 2D van der Waals heterostructures of boron monophosphide and gallium nitride' published in Nanoscale 11 (2019) 21880-21890 has been specially selected to feature in an Editor’s Choice web collection focussing on computational nanomaterials research under the theme Computational studies of nanomaterials for energy, catalysis and electronics.

    It is the first report on out-of-plane piezoelectricity (d33) in 2D van der Waals heterostructures.The experimental verification of this theoretical prediction, followed subsequently and was duly acknowledged to be pioneering in Chem. Soc. Rev., 2022,51, 650-671, is truly rewarding!

  • Department of Science and Technology, Government of India acknowledged our works where induction of superhigh out-of-plane piezoelectricity via stacking one monolayer over the other in the 2D nanostructure has been demonstrated.
