HOUSTON, Texas, Aug. 17 (TNSjou) -- Rice University issued the following news release: * * * Rice lab leads effort to generate thickness-independent piezoelectricity in atom-thick materials * * * There's still plenty of room at the bottom to generate piezoelectricity. Engineers at Rice University and their colleagues are showing the way. A new study describes the discovery of piezoelectricity -- the phenomenon by which mechanical energy turns into electrical energy -- across phase boundarie  more
