Drug-delivering medical feedback loops that would invidualize and improve the effectiveness and safety of drugs, particularly for diabetes management, are of outmost importance nowadays. However, numerous limitations severely prevent commercialization among which the lack of small and implantable power source. The goal of our work is to design such power source, called Biofuel cells (BFC), using glucose/O2 that can be found in the human body. The electro enzymatic reduction of O2 is performed with a multi copper oxidase (Bilirubin oxidase) and remains the limiting part of the BFC.
The objective of the PhD student is to combine electrochemistry and biochemistry to study in details the kinetics of the BOD, in solution and immobilized at the electrode surface. Determination of the rate limiting step will allow us, for example, to improve the enzyme by enzyme engineering. The work is at the interface of chemistry and biochemistry and will request the combination of different analytical and biochemical techniques.
at the Université libre de Bruxelles under the supervision of
Prof. C. Buess-Herman
The researcher will be involved in a project supported by FNRS (Fund for Scientific Research in Belgium) The scientific objective of this research is to correlate the properties and structure of metal electrode-room temperature ionic liquid (RTIL) interfaces to its reactivity.
The project will be developed along two main lines: competition between the ionic liquid and water on the one hand and the ionic liquid and organic additives on the other hand for surface occupancy. Besides more traditional electrochemistry measurements performed at well-defined electrodes (mercury and low-index gold single crystal faces) in-situ spectroscopic measurements (will provides us with molecular information of the interfacial region in presence of RTILs. The description of the electrical double layer in RTILs is a key step in order to be able to correlate the structure of the electrode-room temperature ionic liquid (RTIL) interface to its electrochemical reactivity and to design ultimately interfaces for specific applications.
Position available for one year with probability of an additional year. Starting date : May June 2015
- Researcher in international mobility with max 7 years after date of PhD degree.
- Expertise in electrochemistry. Candidates that have additional experience in ionic liquids and/or spectroscopic techniques will be strongly favored.
Application including full CV should be sent to Prof. C. Buess-Herman

University of Reims Champagne-Ardenne
PhD student: Silicon/titania nanostructures for lithium ion batteries
Laboratoire de Recherche en Nanosciences (LRN) at the University of Reims Champagne-Ardenne is recruiting a PhD student for the Nano-SiBL project in the topic of silicon/titania nanostructures for lithium ion batteries. The role of the PhD project will be synthesis of 1-D silicon and silicon/titania nanostructures by means of electrodeposition. The experimental work will be performed in glove box. The primary goals are synthesis, materials characterization, and study of the fundamental properties for the composites. The developed materials will be studied as a negative electrodes in lithium ion batteries.
As a PhD student you will be working with researchers at the Laboratoire de Recherche en Nanosciences (LRN) Reims, France and Laboratoire de Reactivite et Chimie des Solides (LRCS), Amiens, France. As the successful candidate you will have an experience in electrochemistry and preferably in lithium ion batteries. You will also have demonstrated ability to experimentally realize and characterize 1-D dimensional materials as well as experience of working with state-of-the-art electrochemical techniques. Furthermore, we seek the ability to work effectively both as a member of a research team and independently when required, to meet project outcomes and milestones.
