Offer Description
Tallinn University of Technology School of Engineering, Department of Energy Technology offers a 4-year PhD position in chemical, materials and energy technology.
The proposed PhD thesis topic: "Enhancement of thermal properties of amine-based protic ionic liquids and their performance as LHTES materials"
Supervisors: Senior Researcher Oliver Järvik and Tenured Associate Professor Alar Konist (TalTech)
Abstract
The overall goal of the project is to synthesize, study, and find ways for improving the properties of amine- based protic ionic liquids (PILs) for their potential application as latent heat thermal energy storage (LHTES) materials. The project addresses the following research questions: How is the thermal stability of amine-based PILs affected by the structure? How does the structure affect some thermal properties (specific heat capacity, thermal conductivity) of amine-based PILs? To what extent is it possible to improve the thermal properties using additives? How is thermal cycling affecting the PILs? How do the PILs behave in a confined matrix?
Description
One of the keys for achieving the policy initiatives set by the European Commission is the successful combination of different energy resources and the reduction of thermal energy losses. Waste energy is a significant source of thermal energy losses. A promising technology for its reduction is energy storage and short-distance transportation to consumers utilizing latent heat thermal energy storage (LHTES). More importantly, it can also be used to provide electricity and heat cogeneration in combination with Organic Rankine Cycle solutions and Stirling engines.
For successful application of LHTES the LHTES materials need to have favorable properties: high energy and power density, and low cost. Consequently, materials with favorable properties for LHTES have to be found. A class of “green” materials considered suitable for this is ionic liquids (IL). As trillions of ILs could be possibly created, the selection is further narrowed to amine-based protic ionic liquids (PILs). These materials are not well studied and the data about their properties is scarce. The proposed PhD project deals with the study of amine-based protic ionic liquids, with the main focus on the study of their thermal properties (thermal conductivity, heat capacity), the enhancement of these properties, the effect of thermal cycling on these PILs and the behavior of PILs when they are confined in porous matrices.
It is expected that the project addresses the following research questions: How is the thermal stability of amine-based PILs affected by the structure? How does the structure affect some thermal properties (specific heat capacity, thermal conductivity) of amine-based PILs? To what extent is it possible to improve the thermal properties using additives? How is thermal cycling affecting PILs? How do the PILs behave in a confined matrix?
