Project Title: Engineering thin mesoporous films for development of sensor
Project Status: completed
Duration: 3 years
Date of start: 1. 4. 2005
Funding agency: MHRD
Total cost: Rs. 20 lakhs
Summary of the project: Thin mesoporous (or nanoporous, in this case) silica films have been formed by spin coating a sol-gel reaction mixture from the liquid phase. The pores consist of hexagonal channels of controllable diameter of either 5 nm or 20 nm approximately. This has been verified by AFM, BET etc. Subsequently the pores have been functionalized with OTS or TMCS to make them hydrophobic, so as to make only benzene selectively adsorb in the pores, whereas water is not. As a result it can be used as a way of detecting and separating benzene at a very low concentration of tens of ppm in an aqueous mixture. The adsorption dynamics and equilibrium has been followed by UV-Visible absorbance of peak of benzene. This can be used as a sensor, which can detect very fast, and work reversibly on the basis of presence or absence of a response stimulus, like benzene.

Project Title: Scanning mobility particle sizer (SMPS) for gas-borne nanoparticulate systems
Project Status: Equipment installed and project completed
Duration: 1 year
Date of start: 10. 9. 2005.
Funding agency: IIT Kanpur
Total cost: Rs. 31.8 lakhs
Summary of the project: Gas-borne nanoparticulate systems find an important place in both environmental processes and in various technologies of commercial interest. The former comes under the purview of aerosol science, which involves the study of solid and liquid particles present in the atmosphere, and has implications in air pollution and climatic patterns. On the other hand, nanoparticles of carbon, iron, silica, titania and other metal oxides are synthesized in gas based processes (like chemical vapour deposition, flame and laser ablation reactors) for applications as reinforcing fillers, catalysts, pigments etc. Data on particle size distribution is fundamental to the understanding of the mechanism of formation and properties or new applications of these nanoparticles. The proposed Scanning Mobility Particle Sizing (SMPS) system furnishes this data.
SMPS has been utilized for obtaining particle size distribution data for both outdoor ambient aerosols and common household smoke particles in an enclosed, indoor environment. In the first case, patterns of diurnal and seasonal variations of nanoparticulates and black carbon in the environment has been analyzed and correlated successfully. On the other hand, in the second application area using SMPS; size distribution and chemical composition measurement of indoor aerosols has led us to identify the more harmful aerosols, among common household sources of smoke.

Project Title: General Strategies for Nanoparticles of Controlled Size, Shape and Composition: Magnetite as a Case Study for MRI Applications
Project Status: Finished
Duration: 3 years
Date of start: 7. 5. 2008
Funding agency: DST
Total cost: Rs. 38.94 lakhs
Summary of the project (Up-to date Technical progress report for on-going projects):
Achieved stable aqueous dispersions of magnetic Fe3O4 nanoparticles of diameter < 20 nm, coated with different coating agents – like citric acid, dextran, PAA etc.
Required cytocompatibility levels were obtained for citric acid or dextran coated Fe3O4 nanoparticles by incubating them with HepG2 cells, for up to 24 hrs.
For achieving a stable dispersion, the minimum shell thickness of a coating agent
required for a given particle size was predicted by Monte Carlo simulation.
Through experiments and MC simulation, the states of aggregation of particles were found.
Achieved continuous, silica thin films containing iron oxide nanoparticles (with negligible aggregation) distributed uniformly within the film.
