Characterisation of nanoparticles is important to understand and control their synthesis and applications. However, the main challenges faced currently in characterisation of these materials is the inability and lack of instruments to observe this (technique), measure and manipulate the materials at the nanoscale. In the past, the studies have been carried out on the collective behaviours and properties of a large number of nanostructured materials, which are generally group characteristics. There is a pressing need for developing methods and instrumentation techniques to observe measure and manipulate the individual nanomaterials and nanostructures. This requires development of techniques that are extremely sensitive, accurate and offer atomic level resolution.

Presently, characterisation of nanomaterials is done by using a variety of techniques, mainly drawn from materials science, to probe into the internal structure and properties of a material. Common techniques are electron microscopy (TEM, SEM), atomic force microscopy (AFM) dynamic light scattering (DLS), X-ray photoelectron spectroscopy(XPS); powder X ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF), ultraviolet-visible spectroscopy, dual polarisation interferometry and nuclear magnetic resonance (NMR).

Don’t want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works.

For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to
