1. Microemulsions with Ionic Liquids: Phase Behavior, Microstructure and Solubilization

Project Details

Principal Investigator: Dr. Sandeep R. Patil, Assistant Professor, B. Tech. Program

Funding Agency: Science and Engineering Research Board (SERB)-Department of Science and Technology (DST),Govt. of India

Research Scheme: DST Fast Track Young Scientist

Funding Amount:Rs. 24,58000/-

Duration:June 2014- May 2017


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

Objectives of the proposed project

  • To replace a conventional solvents as a non polar phase by a hydrophobic ionic liquid in a ternary microemulsion systems containing sugar based surfactant.
  • To replace water by a room temperature ionic liquid as a polar phase in a ternary microemulsion systems.
  • Formulating microemulsion systems that are stable over a wide temperature range.
  • To achieve reduction in surfactant concentration required to solubilize two immiscible solvents.
  • To verify the effect of variation surfactant amphiphilicity, oil chain length, ionic liquid type on the phase behavior and microstructure of microemulsion systems.
  • To utilize ionic liquid microemulsion systems for solubilization of metal salts, biomolecules, synthesis of metallic nanoparticles.

Project Objectives

  • To democratize Higher Education by making available quality education to large segments of population- both in rural and urban areas while also including adults who wish to upgrade their skills.
  • The gross enrolment ratio in India for Higher Education is 12.4% but is expected to achieve 21% by the end of the 12th Five Year Plan. The objective of developing this e-Content is to help achieve the above mentioned targets.
  • To provide an innovative system of Higher Education which is flexible in terms of time, place, age of the learner and which maintains comparable standards with the existing formal systems of education.
  • To provide an opportunity to distant learners to be exposed to a rich source of information and guided learning material available at all times, with requisite support machineries that would enable a sound base for learning.
  • To highlight the potential/necessity of future research in areas of health science, biomedical engineering, pharmaceuticals, industry, etc.

Objectives - For Learners

  • To enhance digital literacy and critical thinking skills.
  • To understand the significance of networking and working co-operatively in multicultural environments.
  • To become self learners and lifelong learners.
  • To become effective communicators -verbal and written.

3. Materials Under High Pressure

Project Details

Principal Investigator: Dr. Pallavi Ghalsasi, Associate Professor, School of Engineering and Technology

Funding Agencies

  • Department of Science and Technology-Women Scientists Scheme (A), Government of India, Rs. 23,80,000/-,November 2011-May 2015.
  • Department of Atomic Energy-Board of Research in Nuclear Sciences, Government of India, Rs. 24,37,001/-,August 2012-March 2015.

Research Theme

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.
