5 GHz Band n79 wideband microacoustic filter using thin lithium niobate membrane

Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky, Bruno Garcia

Microacoustic resonators made on suspended continuous membranes of LiNbO3 were recently shown to have very strong coupling and low losses at >= 5 GHz, suitable for high-performance filter design. Employing these simple resonator structures, the authors hav ...

An experimental model approach of biologically-assisted silicate dissolution with olivine and Escherichia coli - Impact on chemical weathering of mafic rocks and atmospheric CO2 drawdown

Philippe Gillet, Bruno Garcia

Chemical weathering of Mg, Ca-silicates and alumino-silicates contributes significantly to the drawdown of atmospheric CO2 over long time scales. The present work focuses on how this mode of weathering may change in the presence of free-living bacteria in ...
