List of courses being offered in Monsoon Semester 2022
Special Centre for Nanoscience (SCNS) is a newly created inter-disciplinary research and teaching centre at JNU. The nanoscience related research topics pursued currently include ferromagnetic nanostructures, magnetic nanocomposites; microwave absorbers; nano-devices; magnetic nanoparticles based target-specific drug-delivery & treatment of cancer cells by radio-frequency-(RF) Hyperthermia; Giant-Magneto-Resistance bio-sensors; nano-biotechnology, bio-sensors, hybrid nanomaterials, anti-bio films, Electron microscopy, ferroelectric/ multiferroic nanocomposites, soft condensed matter, nanoscale interface, etc.
The Centre has faculty members with background in Physics, Electronics, Biology, Materials Science, and Electron Microscopy.
Presently, SCNS common instrumentation facility (CIF) has nanomaterial synthesis and nano-bio synthesis labs consisting of all basic characterization facilities including UV-vis, Raman spectrophotometer, BOD incubator, Laminar Hood, Dynamic Light Scattering, Zeta Potential Measurement, UV-NIR Spectrophotometer, Viscometry, Tensiometry, Potentiostat-Galvanostat, Cell culture facility, Fluorescence Spectrophotometer, Contact Angle Measurement, Elisa Reader, etc.
The Nano-electronics and microwave laboratory consists of DC and microwave probe-stations, microwave nano-devices testing facilities like; Vector Network Analyzer (Keysight Inc. PNA - 44 GHz), Spectrum Analyzer (Rohde and Schwarz Inc. - 40 GHz), Microwave Power Amplifier (Marki microwave) for absorbance testing, angle and temperature dependent variable-frequency Ferromagnetic Resonance (FMR) system. For nanostructure deposition we have multi-target RF Sputtering and thermal evaporation system. 750mJ Pulsed EXCIMER Laser based PLD ultra-high vacuum deposition system is under procurement process. We have photolithography and dry etching facilities for device fabrication. For in-vivo and in-vitro study, we have automated Radio-Frequency Hyperthermia system (MSI AUTOMATION, INC.) on mouse model and human cell-lines.
The Ferroelectrics and Multiferroics Characterization laboratory consists of Impedance Analyzer (20 - 120 MHz, Keysight Technologies), Sawyer Tower Ferroelectric/Multiferroic Hysteresis Loop Measurement Setup; Liquid Nitrogen Cryostat (77 – 800 K) etc.
Nanobio lab consists of human cell culture and storage facility (-20oC). We also have Fluorescence Microscope to monitor nanotoxicity and nano bio-interface. We have Multichannel Electrochemical analyzer to get electrochemical response of multianalytes on a single electrode. Beside this, we have Electro-spinning setup for synthesis of nano-fibres for biomedical application.
Thin-film laboratory has a RF-DC magnetron sputtering system. Presently thin-films and bulk materials of functional oxides are being synthesized using mixed oxide and wet chemistry methods. Lead-free ferroelectrics and antibiofilms are currently being investigated. TEM investigations are an integral part of the research which will be carried out at AIRF of the university. Ion milling machine for preparing TEM samples is being installed at AIRF.
A wide range of analytical facilities including XRD, Transmission Electron Microscopy, Scanning Electron Microscopy, PPMS, Confocal Microscope, and other on-line cell imaging facilities are available at the Advanced Instrumentation and Research Facility (AIRF), which is a central facility of the JNU.
