It was back in 2018 when our team was actively exploring the potential of ionic liquids in membranes for carbon capture. While the results were promising, we were always mindful of their sustainability issues like high costs and non-biodegradable nature. Then one day, Dr Mazhar Amjad Gilani introduced a game-changing idea: how about replacing ionic liquids with deep eutectic solvents (DES) that were hardly being talked about those days. Extremely cheap, derived from plant origins, and potentially even more effective in separations, this idea sparked a new direction in our research.
Since then, this journey has been transformative. We became one of the pioneers in the field, completing nearly a dozen projects, producing two successful PhDs, and publishing several impactful papers. And last week, we reached what I can only describe as the essence or culmination of this work with a brilliant publication by our PhD student, Palwasha Khan, in ACS Sustainable Chemistry and Engineering.
Under the supervision of Dr. Dr-Muhammad Yasin who has been a great contributor and a live wire in broadening our group's applications, this research truly brings the best from our group. It addresses one of the biofuel industry's critical challenges about efficient ethanol-water separation by introducing DES enhanced pervaporation membranes.
Using the COSMO-RS, we identified a menthol/thymol based DES with exceptional hydrogen bonding and selectivity properties. Incorporating this DES into PDMS membranes achieved remarkable improvements in separation efficiency. The DES-PDMS membranes demonstrated outstanding performance achieving excellent separation factors with significant flux rates, aligning perfectly with our COSMO-RS predictions.
This publication brought a feeling of great accomplishment to this amazing journey of last 6 years that is still continuing. We will keep on moving ahead on our path to Sustainability and green engineering.
A huge thanks to Palwasha, Dr. Muhammad Yasin, Dr. Mazhar Gilani, Dr. Asim Khan and everyone who contributed to making this vision a reality.
Efficient separation of ethanol from water is a critical challenge in the biofuel industry, where traditional methods often fall short in terms of energy efficiency and selectivity. To address this, we explore the potential of novel deep eutectic solvents (DESs) to enhance the performance of pervapo...
