Al0.83Sc0.17N Contour-Mode Resonators With Electromechanical Coupling in Excess of 4.5%

Paul Muralt, Luis Guillermo Villanueva Torrijo, Andrea Lozzi

In this paper, we demonstrate the fabrication of contour-mode resonators (CMRs) with Al0.83Sc0.17N as a piezoelectric layer. Moreover, we assess the electromechanical coupling and the maximum achieved quality factor from 150 to 500 MHz. In comparison to pu ...

Nitrogen reduction and functionalization by a multimetallic uranium nitride complex

Rosario Scopelliti, Marinella Mazzanti, Lucile Sylvie Danielle Chatelain, Ivica Zivkovic, Marta Falcone

Molecular nitrogen (N-2) is cheap and widely available, but its unreactive nature is a challenge when attempting to functionalize it under mild conditions with other widely available substrates (such as carbon monoxide, CO) to produce value-added compounds ...
