A SERIES OF EXTRAORDINARY AND UNIQUE BOOKS RECOMMENDED BY MPI

Coupled Tensors of Piezoelectric Materials State

Dr. Ljubisa Peric, Author

426 pages, English language version copyright ©2004 MPI. All international distribution rights reserved.

Some researchers spend a lifetime working towards the understanding of a specific complex problem and, as the culmination of their career, write a technical work offering such a profound and multilevel insight that it could not have been produced in any other way. Our contemporary lifestyle imposes enormous barriers against creating such life-career books, yet this is one. This extraordinary book provides incomparable understanding of piezoelectric materials and their behavior in electro-acoustic transducers.

Dr. Peric's book is available in English exclusively from MPI. To order the book, please use our online store, or read more here.

Some highlights from the mpi-ultrasonics.com site:

Our tube reactors, also based on MMM Technology, are ideal for all through-flow sonochemistry applications providing high intensity, uniform sonication under your complete control. Various sizes available.	Our revolutionary clamp-on ultrasonic systems drive your existing pipes, reactors or pressure vessels, even glass tubes and vessels - with the versatility of MMM ultrasonics.	Ultrasonic systems for the most demanding applications: "MMM Technology" (Multifrequency, Multimode, Modulated Sonic & Ultrasonic Vibrations). Details pages for ultrasonic generators: OF series, OW series, IX series, controllers. MMM ultrasonics manuals on pdf.
An unusual application for ultrasonics - atomization of molten metal alloy. The sonotrode uses a special tip (which is different for atomizing different metals) and water cooling. More information.	Foil immersed for only a few seconds in a benchtop ultrasonic reactor powered by MMM technology. The extent and uniformity of the perforation cannot be matched by any conventional ultrasonic system. The details page includes a small animation and the complete video clip is available for download on our download site.	For high-energy ultrasonic cleaning and sonoreactors, if MMM technology is not required, we also offer this range of top-quality "Push-Pull" transducers (tube resonators), driven by modular generators to suit all power requirements.
We have developed equipment for major manufacturing companies in Switzerland and around the world. Here are some examples:
This is a short video of our prototype ultrasonic compaction unit for reducing the volume of powders in the pharmaceutic industry. (File size 1.5Mb. You may need to download the file first - Right click, "Save target as" and / or download Apple Quicktime).	Another application of MMM Technology - prototype equipment for proving a process of ultrasonic cleaning in supercritical liquid CO2 (more).	Prototype equipment for ultrasonically assisted extrusion of composite plastics. MMM Technology allows the application of ultrasonics directly at the extruder head (more).
