Publication number: 20130057360Abstract: In a bulk acoustic wave (BAW) filter based on laterally acoustically coupled resonators on piezoelectric thin films, one can utilize two distinct acoustic plate wave modes of different nature, for example the thickness extensional (longitudinal) TE1 and the second harmonic thickness shear (TS2) mode to form a bandpass response. The invention is based on the excitation of at least two lateral standing wave resonances belonging to different plate wave modes that facilitate the transmission of signal. The passband is designed by tailoring the wave propagation characteristics in the device such that the resonances are excited at suitable frequencies to form a passband of a desired shape. The bandwidth of the filter described herein may therefore be more than twice that of the existing state-of-the-art microacoustic filters. Consequently, it has significant commercial and technological value.Type: ApplicationFiled: April 21, 2011Publication date: March 7, 2013Applicant: Teknologian Tutkimuskeskus VTTInventors: Johanna Meltaus, Tuomas Pensala

Publication number: 20130009089Abstract: The invention relates to a method for the carbon coating of metallic nanoparticles. The metallic nanoparticles, which are produced using the metal-salt hydrogen-reduction method, can be coated with carbon by adding a hydrocarbon (for example, ethylene, ethane, or acetylene) to the hydrogen using in the synthesis. The carbon layer protects the metallic particles from oxidation, which greatly facilitates the handling and further processing of the particles. By altering the concentration of the hydrocarbon, it is possible, in addition, to influence the size of the metallic particles created, because the coating takes place simultaneously with the creation of the particles, thus stopping the growth process. A carbon coating at most two graphene layers thick behaves like a semiconductor. As a thicker layer, the coating is a conductor. If the hydrocarbon concentration is further increased, a metal-CNT composite material is formed in the process.Type: ApplicationFiled: December 14, 2010Publication date: January 10, 2013Applicant: TEKNOLOGIAN TUTKIMUSKESKUS VTTInventors: Ari Auvinen, Jorma Jokiniemi, Johanna Forsman, Pipsa Mattila, Unto Tapper
