Proposition of a PhD student stipend in the Power Sources Group

 

We propose a PhD student stipend in the Faculty of Chemical Technology, Poznan University of Technology (Poland) for a collaborative work during 48 months in the frame of a MAESTRO project funded by the National Science Centre (Narodowe Centrum Nauki - NCN).

The main objective of the project is to develop new knowledge for better understanding the charging/discharging mechanisms of electrochemical energy storage systems (e.g., supercapacitors) made of porous electrodes and ionic liquids as electrolytes. In order to extend the operating range of the systems, a special attention will be paid to studying the low temperature properties of binary mixtures of ionic liquids. Within the frame of the project, the PhD student will i) develop new carbon materials with controlled porous structure; ii) study the thermal properties of ionic liquids and their binary mixtures in a wide temperature range; iii) determine the properties of electrochemical cells based on ionic liquids and carbons with specially designed porous structure; iv) establish models of the interaction of ions with the pores of electrodes.

This work program is recommended for chemists interested by fundamental and applied science, and aiming at developing a future carrier connected with research and industrial developments. The fellow should possess a good background in materials science and electrochemistry. She/he should be good team player and have ability and willing to taking initiative. Good English speaking and writing is also expected.

Amount of stipend per month: 3,000 PLN netto
Starting date: September 1st, 2017
Duration: 48 months


Candidates wishing to apply are requested to send their Curriculum Vitae, a recommendation letter from their current scientific supervisor, a motivation letter, attested copies of education certificates including grade reports and other documents to
Professor F. Béguin (francois.beguin@put.poznan.pl) before August 11th, 2017.

Proposition of a Post-Doctoral position
Objective of the research:

Effect of ionic liquid confinement in carbon nanopores on electrical double-layer charging

 

We offer a Post-Doctoral position for a collaborative work during 24 months in the frame of a MAESTRO project funded by the National Science Centre (Narodowe Centrum Nauki - NCN).

The objective of the project is to develop high energy electrochemical capacitors (ECs, also called supercapacitors) able to operate in the temperature range from -50°C to 100°C by implementing ionic liquids (ILs). In a first task, the interactions of ions with nanopore walls will be studied during electrical polarization of a carbon electrode with well-designed porosity, while applying binary mixtures of ILs to reach the lowest temperatures. The second task will be to design demonstration models of ECs and to determine their performance parameters vs operational temperature.

Within the frame of the project, the Post-doctoral fellow will design nanocarbons (nanoporous carbons, graphenes, carbon nanotubes...) and implement them together with ILs in supercapacitors. The materials will be characterized by physico-chemical techniques, the IL binary mixtures by thermal techniques, while electrochemical methods will be used to determine the performance of electrodes and supercapacitors.

This work program is recommended for a chemist interested by fundamental and applied science, and aiming at developing a future carrier connected both with research and industrial developments. An excellent background in materials science and electrochemistry is required. Good English speaking and writing is expected in order to participate to international conferences and also to submit publications in high impact factor journals.

Starting date: October 1st
2017 Duration: 24 months
Amount of salary: 5,900 PLN.


Candidates wishing to apply are requested to send the following documents:
i) Curriculum Vitae, including a detailed description of research experience and foreign traineeships (if available), a list of publications and presentations in conferences;
ii) recommendation letters from their scientific supervisors;
iii) a motivation letter;
iv) copies of the most representative research publications (maximum 3);
v) attested copies of education certificates including grade reports and other documents

Unique lignin-based functional fractions: exploring electrocatalytic modification of monomers and oligomers


The fast depletion of fossil fuels as a source for fuels, chemicals, and energy is one of the major challenges our society is currently faced with. Olefins (ethylene, propylene and butadiene) and aromatics (benzene, toluene and xylenes) make up 90 % of the petrochemical production and are the building blocks to almost all other petrochemicals and polymers. The shift towards non-conventional feedstocks, primarily fueled by the fast growing shale gas economy in the US and the abundance of coal in China, will affect the availability of the traditional base chemicals, such as propylene and BTX aromatics. Indeed, shale gas lacks C3- and C4-building blocks as well as aromatics. On top of that, market and societal challenges are asking for biobased molecules. Within these, the aromatics are currently remarkably far less developed than the aliphatic ones. However, companies (e.g. textiles) are currently looking for biobased products, such as polymers, with new functionalities based on renewable building blocks.

Lignin is the most abundant renewable carbon source on Earth, after cellulose. Woody plants typically contain 20-30 % of lignin. An estimated 60-70 million tons of lignin is formed (liberated) into different pulping spent liquors in global pulp and paper industry, with Kraft and sulphite pulping being the two dominating process technologies. More than 95 % of this type of lignin matter is used, together with other dissolved compounds, as a biofuel to generate heat and power. Only less than 5 % of dissolved lignin is recovered from the pulping spent liquors for chemical and material applications.
However, the high functionalization of lignin represents an inherent advantage for producing molecules with greater complexity and wider application scope. Hence, lignin represents an excellent alternative feedstock for the elaboration of chemicals and polymers which is currently rarely exploited, rather than just being burnt as a process energy source. By generating methods for the material utilization of lignin the gap in the value chain of complete lignocellulose processing to value-added products can be closed.

Taking into account the wide availability and low cost of lignin, this natural material may be an excellent candidate for chemical modifications based on its highly functionalized character, allowing to potentially access a wide variety of polysubstituted benzenes. - Although there has been a growing interest over the last decades to use lignin as an attractive alternative to phenols due to the structural similarities between lignin and phenolic fractions, the low reactivity of lignin is a major issue. Key in the approach of developing lignin-based materials are the controllability of the lignin fragments, concerning molecular weight, phenolic number, functional groups, hydrophobic/hydrophylic character, reactivity etc.. This is only possible via partial depolymerization, fractionation/separation and conversion into the right building blocks (pure or controlled mixtures).

The aim of this Postdoctoral research topic is to look at the electrocatalytic modification/functionalization of lignin-derived compounds (monomers – oligomers) to promote their suitability for different application fields, e.g. adhesives, coatings, plastics and other industrial applications by increasing their reactivity, and hence to contribute to creating new wood/lignin applications.
