About me

Research fields:

  • Atmospheric corrosion, corrosion inhibition
  • Biomimetic cell membranes
  • Water surfaces
  • Polyelectrolyte multilayers

Expertise in techniques:

  • Vibrational sum frequency spectroscopy (VSFS)
  • Infrared reflection/absorption spectroscopy (IRAS)
  • Langmuir / Langmuir-Blodgett films
  • Quartz crystal microbalance (QCM)

My research is focused on studies of surface phenomena in the fields of atmospheric corrosion and biochemistry. The main technique used is the surface specific laser technique VSFS.

Atmospheric corrosion:

Model in-situ studies of indoor atmospheric corrosion processes at various coated and uncoated metal surfaces are performed with a multianalytical approach. Recent studies involve investigations of how self-assembled monolayers of alkyl thiols and selenols can be used as corrosion inhibitors to protect copper surfaces exposed to a humid atmosphere containing formic acid, a common indoor corrosion promoter. A combination of three analytical techniques has allowed examinations of the nature (IRAS) and mass (QCM) of the corrosion products formed, as well as induced changes in the order and orientation of the corrosion inhibitor (VSFS) to be performed. 

Biomimetic cell membranes:

Langmuir and Langmuir-Blodgett films are prepared to model natural cell membranes, and VSFS is used to study their packing, order, orientation, hydration, oxidation, and interactions with drugs.
