Invited Speaker / Conférencier(ère) invité(e)

Despite almost 90 years of study the physiological role of vitamin E is still muddied by controversy. Research, both fundamental and clinical, has generated conflicting and contradictory results throughout literature.
Deficiency in α-tocopherol (aToc), the physiological relevant form of vitamin E, has been show to lead to a multitude of conditions including infertility and neuromuscular...

RfaH is a compact two-domain multi-functional protein from the bacteria $Escherichia\ coli\ (E. coli)$. Its C-terminal domain (CTD) has been shown experimentally to be able to undergo a complete conformational change from an $\alpha$-helix bundle to a $\beta$-barrel structure. The $\alpha$-helix bundle to $\beta$-barrel fold switch accounts for the observed dual role of RfaH, whereby it...

2144. Capillary levelling of a liquid stepped film supported on an immiscible liquid film (G)*

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Thin polymeric films have numerous technological applications and their stability has garnered intense interest. The stability and flow of a thin, viscous film is sensitive to the boundary conditions as the film thickness approaches the nanoscale. Here we probe a liquid-liquid boundary condition: a stepped polymer film is placed above a different, immiscible polymer film. The ensemble is...

2222. Voltage-driven translocation through a nanopore: How can we define the capture radius? (G)*

In most polyelectrolyte translocation studies, regardless of the shape of the pore and the strength of the driving force, the polymer chain has to go through three basic steps: (i) diffusion; (ii) capture; (iii) threading. The capture process remains rather ill-understood because it cannot easily be visualized or inferred from the blockage current measured across the nanopore. To estimate the...
