Ph.D. Thesis (completed 2018)

Mineral surfaces control the adsorption of water vapour and other atmospheric gases (e.g CO2, SO2) as well as aqueous species formation. These reactions are central  to  atmospheric, environmental, (bio)geochemistry and even astrobiological studies.

My Ph.D. thesis (main supervisor: Jean-François Boily) was focused on the adsorption/condensation of water vapour and ice at mineral surfaces, as well as their relationship to  cryosalt minerals and their interactions with CO2. Mineral-bound thin water and ice films are directly relevant to, (bio)geochemistry, astrobiology and atmospheric sciences. For instance,  cloud formation can often be triggered by the condensation of water vapor on tiny mineral dust particles. My work involves the study of over 19 different minerals relevant to the atmosphere, terrestrial systems, and even potentially  for planet Mars.  These minerals are of different i) surface structures and (ii) morphologies, (iii) chemical compositions and (iv) particle sizes. Examples  include synthetic iron (oxyhydr)oxides, silicates, clays Arizona Test Dust (ATD) and Icelandic volcanic ash.


I have predominantly used Fourier Transform Infrared Spectroscopy (FTIR) for my research. Using various reaction IR cells, I have experience in operating systems from ultrahigh vacuum to pressurized environments, and with temperatures ranging from -130°C to 700°C. Additionally, I have gained, from by  MSc work in Physics, experience with Raman spectroscopy and spectroscopic ellipsometry to characterize semiconductors coated with thin carbon-based fullerene (C60) films.
