The equipment uses a single crystal diamond-tipped tool to manufacture high-quality precision components, like molds, lenses, mirrors/reflectors, diffractives, cavities from metals, semiconductors, acrylic, and other materials. Not just flat and spherical surfaces, but complex profiles like paraboloids, aspheric, free-form, etc. can be processed with micron level form accuracy.

The Illumina next-generation sequencing (NGS) method is based on sequencing-by-synthesis (SBS), and reversible dye-terminators that enable the identification of single bases as they are introduced into DNA strands.

This is the first remotely operable LEAP facility in the world. Any researcher in India can use the facility by contacting the NFAPT management. More details can be found on https://nfapt.iitm.ac.in . IIT Bombay users should submit the proposals for measurement to the Facility Management Committee chaired by head of SAIF/CRNTS.

When matter absorbs ultraviolet radiation, the electrons present in it undergo excitation. This causes them to jump from a ground state (an energy state with a relatively small amount of energy associated with it) to an excited state (an energy state with a relatively large amount of energy associated with it). It is important to note that the difference in the energies of the ground state and the excited state of the electron is always equal to the amount of ultraviolet radiation or visible radiation absorbed by it.

The sample is imaged from different directions, ideally across an angular range of at least 180°. A single image at one particular angle is called a projection. Computer algorithms can be used to reconstruct the internal, 3-dimensional (3D) structure of the sample from a series of projections. The reconstructed volume can be visualized in different ways; for example slice by slice (also referred to as virtual cross-sectioning), or by rendering a 3D view of individual internal features.

Electrospray ionization mass spectrometry is a desorption ionization method. Desorption ionization methods can be performed on solid or liquid samples and allows for the sample to be nonvolatile or thermally unstable. This means that ionization of samples such as proteins, peptides, oligopeptides, and some inorganic molecules can be performed.

It can perform all analysis that a typical GC-TOF-MS can perform. Its particular benefit is for analysis of organic compounds from complex mixtures and environmental samples where high end separation is involved. It involves two columns (that can achieve separation based on different attributes). A thermal modulator ensures cryo focusing of effluent from the first column before its release to the second column. The two-dimensional output helps in resolving the peak of target analytes even when matrix interferences are present. The enhanced spectral collection rate of the TOF-MS detector together with the software capabilities can help in de-convolution of co-eluting compounds.

X-ray diffraction (XRD) is an instrumental technique to study crystalline materials. An X-ray beam is focused on the planes of the atoms forming the crystal lattice of the material under study. Of the incident beam, a part is transmitted, a part is absorbed, a part is refracted and scattered while the remaining part is diffracted. On diffraction of the x-ray beam from the sample, the distances between the planes of the atoms constituting the sample can be obtained by applying the Bragg's law. Bragg's law is given as nλ=2d sinθ, where n is the order of the diffracted beam, λ is the wavelength of the incident x-ray, d is the distance between adjacent planes of atoms and θ is the angle of incidence of the x-ray. With known values of λ and θ the d-spacings of the atoms in the sample can be calculated. The characteristic set of d-spacings and theirs intensity generated in a typical X-ray scan provides a unique "fingerprint" of the phases present in the sample. On proper interpretation with comparison with standard references available, the sample material can be identified from the respective "fingerprints" obtained.
