Model: SmartLab 9kW rotating anode x-ray diffractometer

Powder X-ray Diffractometer

The temperature dependent Powder X-ray diffractometer is built on 9 KW rotating anode x-ray generator with NaI Scintillation counter detection system. Copper anode is used as the target material with fine focus filament as the cathode. Low temperature down to 12K is achieved using closed cycle liquid Helium cryostat. This system has theta-theta goniometer arrangement which keeps the sample horizontal and stationary. The Cross Beam optics technology used in this systems helps in easy changeover from Bragg-Brentano para focusing to high intensity parallel beam geometry and vice versa depending on the application. There is also small angle x-ray scattering unit attached to the system. The attachments for the future installations include high temperature, Grazing Incidence X-ray Diffraction (GIXRD), X-ray Reflectometry (XRR) units.

High Resolution Transmission Electron Microscope (TEM) – Energy Dispersive Spectroscopy (EDS)

An electron microscope uses high energy electron beams for the illumination of samples, instead of light so that magnification to the tune of a million times (10,000,000 x) and subnanometer resolution can be achieved. Electron microscopes are essential tools for characterizing nanomaterials as they provide an array of information such as topography, morphology, composition and crystallographic information. In the nanoworld, 'believe what you see' and electron microscopes such as TEM provides realistic images of nanomaterials. Infact, one of the major reasons for emergence of the field of nanotechnology is the invention of modern microscopes including the electron microscopes that have very high magnification and resolution in the nanometer length scales. In TEM, high energy electron beam passes through a very thin sample and constructs a two dimensional image of the sample. High resolution TEM can achieve atomic resolution. TEM also can be coupled with EDAX for elemental identification. Crystalllographic information of samples can also be obtained using selective area electron diffraction in TEM. EDS can be used to study chemistry of the materials and to do elemental mapping.

Nuclear Magnetic Resonance Spectrometer - 500 MHz

Information about the structure, conformation and dynamics of small and large molecules can be obtained in the solution and solid state using NMR Spectrometer. Apart from common nuclei's like --1H and 13C, we can also record NMR spectra for other active nuclei's such as 19 F, 11B, 15N, 2D, 127I, 207Pb, 7Li, 6Li, 199Hg, 103Rh, 31P, 111Cd etc. Due to recent advances in spectroscopic techniques two dimensional NMR spectroscopy has become powerful tool to derive unique structural information of small and large molecules, some of the most useful techniques include 1H-1H COSY (Correlation Spectroscopy), Double quantum filtered 13C-1H COSY, Carbon detected 13C-1H COSY, Proton detected 1H-13C COSY: HMQC (Heteronuclear Multiple Quantum Correlation), Proton detected, Long Range 1H-13C Heteronuclear correlation: HMBC (Heteronuclear Multiple Bond Coherence), DQF (Double Quantum Filtered)-COSY, 1-D TOCSY (Totally Correlated Spectroscopy), 2-D TOCSY, HMQC- TOCSY, ROESY.

Confocal Microscopy

The wave nature of light and the associated diffraction not only undermine resolution of common light microscope but also impose difficulty of miniaturizing photonic devices such as fiber optic cable and couplers. In order for light based circuitry to be competitive with current electronic circuits and to overcome the speed limitations of electronics, this size compatibility is a central challenge. Some of these tasks could be carried out by molecular devices such as photonic wires, and molecular switches involving organic fluorophores, inorganic quantum dots, nanoparticles, nanocomposites. Further, the advancement of DNA nanotechnology, in recent years, combined with nanomaterial offers a great opportunity to improve the nanotechnology research, biomedical application and in living cells.

Femtosecond Laser System

Transient absorption (TA) spectroscopy encompasses a powerful set of techniques for probing and characterizing the electronic properties of molecules or materials. This technique is used to study ultrafast photophysical and photochemical processes by monitoring transient states (e.g., excited states, charged species). These states are accessed upon absorption of photons and essentially represent higher energy forms of the system, differing from the lowest energy ground state in the distribution of electrons and/or nuclear geometry. Our femtosecond TA setup consists of a Ti:Sapphire regenerative amplifier (Spitfire Ace, Spectra Physics) seeded by an oscillator (Mai Tai SP, Spectra Physics) as light source. The laser output from the amplifier having wavelength 800 nm, pulse width < 35 fs and energy 4 mJ per pulse is divided into two beams to generate pump and probe pulses. A white light continuum (WLC) probe in the visible wavelength range is obtained by sending a small fraction of 800 nm focused beam through sapphire crystal. Probe is splited into two beams and detected as sample and reference separately to eliminate low frequency laser noises. A mechanical chopper of rotational frequency 500 Hz is used to create the pump blocked and unblocked conditions for the detection. TA spectra is recorded by CCD arrays after dispersion using a grating spectrograph (Acton spectra Pro SP 2358).

Single Crystal X-ray Diffractometer

The most common experimental method of obtaining a detailed structure of a molecule, that allows resolution of individual atoms, single crystal X-ray diffraction (SCXRD) is performed by analysing the pattern of X-rays diffracted by an ordered array of many identical molecules (single crystal). Many pure compounds, from small molecules to organometallic complexes, proteins, and polymers, solidify into crystals under the proper conditions. When solidifying into the crystalline state, these individual molecules typically adapt one of only a few possible 3D orientations. When a monochromatic X-ray beam is passed through a single crystal, the radiation interacts with the electrons in the atoms, resulting in scattering of the radiation to produce a unique image pattern. Multiple images are recorded, with an area X-ray detector, as the crystal is rotated in the X-ray beam. Computationally intensive analysis of a set images results in a solution for the 3D structure of the molecule.

BET surface area

The adsorption/desorption isotherms and pore volumes of the adsorbents were determined by nitrogen adsorption-desorption isotherms, measured at 77 K using Quanta chrome Autosorb 1C system. The samples were degassed at 200oC under vacuum before starting N2 adsorption. Surface area and pore volumes (or pore size distribution) were determined using the Brunauer-Emmet-Teller (BET) equation, Barret-Joyner-Halenda (BJH) and DFT methods respectively.

All chromatographic separations, including HPLC operate under the same basic principle; separation of a sample into its constituent parts because of the difference in the relative affinities of different molecules for the mobile phase and the stationary phase used in the separation.

Rheology

Rheology is the study of the flow of matter, primarily in a liquid state, but also as “soft solids” or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. It is a branch of physics which deals with the deformation and flow of materials,both solids and liquid.

Chemisorptionanalyser(BEL CAT2)

Chemisorption is a kind ofadsorption which involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbant surface. Examples include macroscopic phenomena that can be very obvious, likecorrosion, and subtler effects associated withheterogeneous catalysis. The strong interaction between theadsorbate and thesubstratesurface creates new types of electronicbonds.
