PhD student in Physical Chemistry (B) at the Department of Materials and Environmental Chemistry.
The Department of Materials and Environmental Chemistry (MMK) is one of the largest departments at the Faculty of Natural sciences with about 130 employees. Research activities of MMK in the areas of Materials and Solid-State Chemistry focus on different classes of materials; e.g. ceramics and glasses, self-assembled and porous materials, and soft matter. The work often encompasses synthesis, characterization by X-ray and neutron diffraction and electron microscopy, NMR studies, modelling with computer simulations of materials with a potential for various applications. Environmental aspects are an important part of the research activities.
Project title: High Performance Thermoelectric Materials by Thermal Decomposition of Tailor-Made Metalorganic Precursors in Ionic Liquids.
Supervisor: Professor Anja-Verena Mudring, firstname.lastname@example.org.
In most energy conversion processes and in many equipment or chemical processes heat is dissipated which represents substantial energy losses. Thus, recovery of lost heat and conversion to high-value electric energy is an important, integral contribution to a robust and resource-efficient energy system. For this efficient thermoelectrics are needed that can recover the waste heat and convert it back to high-value electric energy. The project aims at developing improved thermoelectric materials for waste heat recovery through decomposition of metal-organic precursors with defined composition in task-specific ionic liquids (ILs) by microwave heating and subsequent mild compaction. This approach allows in a unique way to independently optimize the three key physical properties of a thermoelectric material where typically the optimization of one property is only possible at the expense of the other: Seebeck coefficient (single source precursor: defined charge carrier concentration, electric (IL: templating agent not compromising conductivity) and thermal conductivity (compaction: preserves microstructure). The PhD project will be supported through a grant from the Swedish Energy Agency, Energimyndigheten.
The successful candidate should have a background in chemistry, materials science, chemical engineering or a related subject. The position required the synthesis, structure and reactivity characterization of organometallic compounds as well as studying their transformation to the corresponding nanoscale materials, interpretation of data and scientific presentation. The project involves synthetic organic chemistry and several characterization methods, such as NMR, MS, vibrational spectroscopy, X-ray diffraction, thermal analysis as well as computational modelling. Experience in those techniques and methods is beneficial, although not strictly required.
