Listening to the Nanopores : Smart Nanomaterials Use Humidity to "Tune" Hypersound Like a Guitar String

What if humidity could act as a control knob for hypersound ? Researchers have shown that nanometer-scale pores in thin films can “sense” moisture in the air and dynamically change how they trap sound, turning ordinary water vapor into a tool for controlling vibrations at the nanoscale. Nanophononic devices — structures that control sound at the nanoscale — are emerging as key components for ultrafast signal processing, telecommunications, …

C2N Highlights 2025 : a year in review

Here is our Highlights 2025 report. This booklet presents an overview of the activities carried out and the research conducted within the laboratory. It also highlights the key institutional and scientific moments of 2025. These highlights once again demonstrate C2N’s position as a leading laboratory at the local, national, and international levels, made possible by the dedication and commitment of all its teams: researchers, professors, associate professors, engineers, technicians, administrative …
