Invited Speaker / Conférencier(ère) invité(e)

Laser-induced breakdown spectroscopy (LIBS) is a real-time spectrochemical technique that involves performing time-dependent optical emission spectroscopy on high-temperature laser-induced microplasmas. The use of a focused laser beam allows one to make sensitive assays of the elemental composition of specimens while requiring only micrograms of analyte mass. Numerous medical and biomedical...

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

Purpose: In the context of previous analysis of dynamic nuclear medicine acquisitions, a
lack in available software was noticed: commercial systems are too opaque and do not
allow a sufficiently flexible use. To tackle this challenge, home-made scripts were
devised, which were then packaged for wider use. The goal is two-fold: dissolve
difficulties specific to dynamic nuclear medicine...

Our group is developing a plastic fiber optic probe dosimeter based on a radiochromic sensor for real-time in vivo dosimetry. The active component of the probe material is a lithium pentacosa -10, 12-diynoate (LiPCDA) coating on the order of microns in thickness. In radiochromic optical dosimeters both sensitivity and active material thickness variations in manufacturing can lead to...

We are well aware that every human can be identified by their unique fingerprint. Taking inspiration from natures’ this wonder, there is an exclusive feature to identify different molecules/chemicals in materials science. We can find this attribute in the way molecules vibrate. Different molecules have different vibrational modes depending on their chemical constituents, bonding strength,...
