Facility Description
SAXS is an analytical characterization tool used to determine the structure of particle systems in terms of averaged sizes or shapes. The materials can be solid or liquid and they can contain solid, liquid or gaseous domains (so-called particles) of the same or another material in any combination. The method is accurate, non-destructive and usually requires only a minimum of sample preparation. Applications are very broad and include the metal, cement, oil, polymer, plastics, food and pharmaceutical industries and can be found in research as well as in quality control.
The state of the art machine just installed at SAIF IITB provides opportunities to analyze samples in various environments (ambient, low and high temperature, high pressure, and flow conditions).
X-rays are scattered at the electrons of the atomic shell. During the scattering process the electron is starts oscilating. It
becomes a dipol and a spherical wave is sent out. The wavelength and energy of the scattered wave does not change (elastic scattering).
By detecting x-rays scattered at different angles, different sample information is gained at different resolutions: SAXS has nanoscale resolution (good for samples 100-1 nm in size) while WAXS has atomic resolution (1-0.1 nm). Due to this, SAXS can be typically used to analyse larger scale bulk microstructure within a sample, while WAXS is more similar to x-ray diffraction.

Applications
1)The Properties of functional materials are strongly linked to their size, shape, interaction potential.
2)Functionalization of self-assembled structure.
3)Self assemblies of amphiphilic molecules called micelles are often utilized to stabilized water –insoluble functional substances such as vitamins, perfumes and many more in water based products.
4)Pharmaceutical materials- Drug delivery systems are made of nano-carrier.
5)Food and nutrients- The structural information has become more and more important for developing better texture and functionalities that make food product wholesome.
6)Nano size inorganic particles are used in a wide verity of industrial fields such as cosmetics, paints and ceramics production.
7)Nano composites
8)Lipoproteins- SAXS often fast and precise measurement of LP particles using only small amount of samples.
