In recent years, microemulsions have been evaluated as unique and versatile reaction media for a variety of chemical reactions, such as nanoparticle preparation, organic synthesis, bioorganic synthesis, and so on. Microemulsions are optically transparent, thermodynamically stable solutions of at least three components comprising two immiscible fluids and a surfactant. Such mixtures of water, oil, and surfactant exhibit a rich variety of microstructures within single-phase microemulsion domains and a rich variety of liquid crystalline or mesophases, in addition to many different kinds of multiple phase domains.1 Ionic liquids (ILs) have attracted more and more attention in recent years, because of their unique properties such as low vapor pressure, high thermal stability and wide liquid range.2

Every material changes its behavior as a response to high pressure. Interestingly, nature also uses high pressure high temperature synthesis technique to convert carbon into diamond deep inside Earth's mantle. Diamonds in turn are widely used in investigation of various spectroscopic properties of materials under pressure due to theirhardest behavior and optical transparency.With the advances in technology, today it is possible to mimic extreme high pressures in the laboratory.
In our laboratory we are having different Diamond Anvil Cells (DAC) to generate pressure in the range of40-50 GPa and optical stereo microscope (SMZ1000) with polarizer-analyzer and 4x-160x magnification.Application of pressure to a material inside DAC may change its vibrational (Raman or IR spectroscopy) properties, band gap (UV-visible spectroscopy), structure (X-ray diffraction), electrical resistance (Resistivity). The changes in these properties/behaviour can be correlated to variation in bond vibrations, bond lengths, symmetry and shape of the material. We are basically interested in understanding these aspects in negative thermal expansion materials and organic-inorganic hybrid compounds.
We are investigating applications of high pressure techniques (typically exploited for metallic, covalent and ionic bonded compounds) for relatively weakly (hydrogen or π - π) bonded molecular compounds. We are also involved in in-situ microscopy of crystal growth and new phases of materials under high pressure.
