There is ongoing recruitment for the areas listed below (for Ph.D. and master's students as well as post-docs). Please contact Dr. Y Roy for further details.
Arsenic remediation from groundwater: India has the largest population affected by arsenic contamination in groundwater. The presence of this species in drinking water causes severe illness in affected populations. Therefore, arsenic remediation continues to be an important research topic. The candidate will focus primarily on adsorption for arsenic remediation from groundwater. The work would be partly experiment-based and partly simulation-based.
Membrane-based gas separations for industrial applications: The isolation of a gas from a binary or multi-component mixture is relevant to several practical applications. Examples include hydrogen isolation from syngas and nitrogen isolation from air. Several aspects of these operations remain to be optimized, primarily to reduce cost and energy requirements, as well as isolate more of each valuable gas from the mixture. A simulation-based project will be offered to design a techno-economically optimized membrane system for an application of the student’s interest. Promising results from simulation may attract industrial support to conduct experiments.
DMSO-water separation using pervaporation: DMSO (dimethyl sulfoxide)-water mixtures comprise effluent streams from the pharmaceutical industry, microelectronics industry, and various other industries. In order to prevent environmental pollution and human hazard due to the dumping of this effluent into the environment, recovery of these solvents, and their subsequent reuse must be practiced. Recent results show that this separation can be achieved using the membrane technology pervaporation (please see group homepage for more details on pervaporation), which would reduce energy requirement compared to the state-of-the-art distillation methods – comparison between these two approaches is the focus of this project. The project will primarily be simulation-based, although some experiments to verify the results would be possible.
We are actively seeking post-doctoral candidates to be recruited via the IoE and CV Raman programs at IISc (https://iisc.ac.in/post-docs/). Other schemes such as the SERB-National Post Doctoral Fellowship (NPDF) can also be supported. The research areas are the same as listed above.
