IAS Visiting Fellow Dr Ardila Hayu Tiwikrama delivers a seminar on their research, fully titled "A novel generation of sorbents capable of capturing carbon dioxide using ionic liquids and deep eutectic solvents" -

In large-scale industrial applications, the high cost and energy associated with CO2 capture from flue gases is a significant obstacle. Therefore, it is crucial to develop a technically and economically efficient technology for CO2 capture. In this study, the CO2 absorption potential of functionalized DESs and ILs is investigated. The improvement of the absorption capacity of ILs can be achieved by incorporating CO2-philic functional groups, such as amine, into the cation and/or anion moiety. The anion component of ILs is more efficiently functionalized than the cation component. In the present study, the solubility of CO2 in diisopropylethylammonium-based ILs and polyol-based DESs with a certain molar ratio was measured using a variable volume high-pressure cell at temperatures from 298.15 to 373.15 K and pressures up to 150 bar. The experimental vapor-liquid equilibrium (VLE) data were correlated with the PC-SAFT. Novel ILs and DESs with promising absorption capacities are conceivably developable.

Arrivals from 11:45 am for a 12:00 noon start. For those joining in-person, lunch will be served after the seminar from 1:00pm.

This event is hybrid format, please use the required booking button at the bottom of the page to choose either in-person or online attendance.
(Please note that in-person spaces are limited and booking is required, so we can manage numbers for catering and also the space in the seminar room)

By booking a place at this event, attendees agree to behave in a respectful manner such that everyone feels comfortable contributing as they wish. The IAS reserves the right to eject anyone who does not abide by this policy.

IAS seminars are typically recorded, minus any Q&A sessions at the end, again to encourage contributions. The recordings are then uploaded to our website on a Fellows bio page and/or Programme page, along with our IAS YouTube Channel. If you are not able to attend a seminar live, please do still register as we will email everyone who registered to let them know once the recordings are made available.
