We launched the company while still completing our master degrees, which meant we were knee deep in fundamental research in chemistry. One of the motivations – especially for me – of setting up our laboratory was to have our very own scientific playground. As chemists,

Research Note – Alexis St-Gelais, M. Sc., chimiste Essential oils can sometimes be surprising. It so happens that well-known species that have been frequently studied yield, in particular conditions, peculiar volatile molecules that are otherwise not widely recognized to be characteristic of the plant. When such an observation is made, it is useful to publish
