Research group of physical chemistry and electrochemistry

Keywords: physical chemistry, electrochemistry, conducting polymers, scanning electrochemical microscopy, fast Furrier transformation based electrochemical impedance spectroscopy, fuel- and bio-fuel cells, surface modification.

The research team is focused on synthesis of conducting polymers and evaluation of mechanisms of this synthesis, investigation and application of scanning electrochemical microscopy, development of biofuel cells.

 

Research group activities

Our research group is focused on three main topics:

• Synthesis of conducting polymers and evaluation of mechanisms of this synthesis. Conducting polymers are applied in various research areas, sensors, biosensors, batteries, super-capacitors. Therefore it is very important to evaluate polymerization mechanisms of these conducting polymers in order to create new structures suitable for various technological applications with tailored properties.
• Investigation and application of scanning electrochemical microscopy and improvements of scanning electrochemical microscopy, by advanced electrochemical techniques such as fast Furrier transformations. Scanning electrochemical microscopy is new advanced method which could be applied for electrochemical investigation of sensor and biosensor surfaces, therefore new advances in this research direction could have number of technological and scientific applications.
• Development of biofuel cells based on microorganisms and conducting polymers that could solve some problems in energetics and environmental pollution.

Proposal

• We offer our knowledge and experience in synthesis of conducing polymers, electro-optical, electrochemical quartz-crystal micro-balance based and ellipsometry based measurements for various technological and scientific applications including biotechnological applications and investigations of surfaces.
• We are looking for partners for further improvements of scanning electrochemical microscopy.
• We seek partners for developing competitive research projects targeting HORIZON 2020 and other international programs.
