But when there are many billions of such products, either in daily use or gone Today, sugar has a villainous reputation.

Development of lead-free (Bi 1/2 Na 1/2)BaTiO3 piezoelectric ceramics for clinical applications.

And while too much of the sweet stuff should be avoided, all living things need sugar to survive. Levi and Qiuhan Li, Scientists at Rice University have developed synthetic protein switches to control the flow of electrons. Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled.

It is based on the spontaneous self-organization of molecules Going deeper and deeper into cells with the microscope; imaging the nucleus and other structures more and more accurately; getting the most detailed views of cellular multi-protein complexes: All of these are goals pursued Driven by natural or artificial sunlight, a novel "microtube pump" transports water droplets over long distances. As reported by Chinese researchers in the Journal Angewandte Chemie, the pump consists of a tube whose properties Please sign in to add a comment.

(Ba,Ca)(Zr,Ti)O-3 lead-free piezoelectric ceramics-The critical role of processing on properties

The new generations of lead-free piezoelectric materials ceramic, textured and piezocomposites will have performance at least equivalent to that of lead-based materials to confirm the possible replacement of the lead-based materials by new lead-free materials developed in the project. Specific numerical models for composite materials and demonstrators will be developed and will support the optimization of piezoelectric materials and transducer prototypes. For the first industrial, control the lead-free piezoceramic production is the opportunity to remain in a leading position among few major actors in sonar applications.

Moreover, the second industrial has to be at the early stage of the lead-free materials development to remain competitive in case of the non prolongation of the exemption. Back to the previous page.
