Functionalization and Surface Science of Nanostructured Materials

Niroj Kumar Sahu is an Associate Professor at the Centre for Nanotechnology Research at the Vellore Institute of Technology, India. His areas of research are as follows: Condensed matter physics, physics and chemistry of nanomaterials; magnetism and magnetic materials; ferrites based nanostructured magnetic materials for magnetic hyperthermia, thermochemo-therapy, and magnetic resonance imaging (MRI); fabrication, surface functionalization and self-assembly of metallic, oxides and alloy nanostructured materials their application applications in energy storage, removal of environmental hazard and biomedicine. Dr. G. Swati is a Senior Assistant Professor at the Centre for Nanotechnology Research (CNR), Vellore Institute of Technology, Vellore, India. Her major research areas include surface-functionalized nanomaterials and quantum dots for energy harvesting, thermoluminescent materials for dark vision display, luminescent security ink for anti-counterfeiting, and nanomaterials for optoelectronic applications. Dr. Swati has published 17 research papers in peer-reviewed journals, 3 book chapters, and 1 patent. She is a lifetime member of the Luminescence Society of India (LSI), and sessional member for the Indian National Science Academy (INSA). Dr. P. Sathyanarayanan is a Senior Assistant Professor in the School of Electronics Engineering (SENSE) at VIT University Vellore campus, Tamil Nadu, India. He obtained Ph.D. in Physics from the Nanostructured Physics Group of Hasselt University, Belgium, and worked as a post-doctoral researcher on nanofabrication of molecular structures through nano-chemistry at the University of Lille, France. Dr. Sathyanarayanan has expertise in the ultrafast synthesis of nearly mono-disperse, well-ordered, and well-separated inorganic nanostructures using the micellar technique, with applications across different fields including optics, optoelectronics, magnetic recording-media, catalysis, chemical reactivity, nanotubes, nanowires, and biomedicine. He has also extensively researched low-pressure CVD-based growth of carbon nanostructures grown in-situ and characterization by XPS, AFM, SEM, TEM and Raman Spectroscopy, and recently developed a new design and fabrication of nanofluidic channels based on 3D prototyping of Hydrogen Silsesquioxane (HSQ) using electron beam lithography. Dr. Sathyanarayanan has published 15 research papers in peer-reviewed journals.
