For practical application, the functional piezoelectric film in microelectromechanical systems should meet the requirement of physical properties, as well as the mechanical properties. In this article, 0.5Ba(Ti0.8Zr0.2)O3-0.5(Ba0.7Ca0.3)TiO3 (0.5BZT-0.5BCT) thin films with varied properties were prepared on (100) Si substrates via a sol-gel technique at different annealing temperatures. The effects of the annealing temperature on the morphology, piezoelectricity, hardness, and elastic modulus were studied. Particular attention was paid to the surface frictional behavior of films, and the changes in the friction force can be radically explained in terms of differences in the hardness/elastic modulus ratio and the residual stress of films. …

OnLine Social Networking sites (SNS) hold a vast amount of information that individuals and organisations post about themselves. Investigations include SNS as sources of evidence and the challenge is to have effective tools to extract the evidence. In this exploratory research we apply the latest version of a proprietary tool to identify potential evidence from five SNS using three different browsers. We found that each web browser influenced the scope of the evidence extracted. In previous research we have shown that different open source and proprietary tools influence the scope of evidence obtained. In this research we asked, What variation …
