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, …

Inspiring women scientists…

They are astrophysicists, biologists, mathematicians, engineers, climatologists… All passionate, all bold, they have forged their own paths in the world of science. Their stories are powerful invitations to dream, to dare, and to explore—encouraging girls to pursue careers in science. Among them is Muriel Thomasset, head of the MultiPhysics platform at C2N. Under the direction of Isabelle Vauglin & Anne Haguenauer, with carte blanche contributions from Valérie Masson-Delmotte …
