First ever Solar Thermionic-Thermoelectric Generator released and discussed
An article published in the prestigious magazine Advanced Energy Materials (https://doi.org/10.1002/aenm.201802310) describes the concept, the development process of active materials and the demonstration of the first concentrated solar energy converter by combining thermionic and thermoelectric effects (ST2G – Solar Thermionic-Thermoelectric Generator). The innovative system, potentially capable of a conversion efficiency higher than 40%, is almost entirely developed within the CNR, by the DiaTHEMA Lab of the ISM in collaboration with the Institute of Science and Technology of Ceramic Materials (ISTEC) and the Tel Aviv University. The development of innovative materials and devices for the conversion of concentrated solar energy into electrical and thermal energy is a topic of great interest for the scientific and industrial world. The conversion modules developed by the CNR operate at temperatures between 700 and 1100 ° C, combining the thermionic and thermoelectric effects. To reach such temperatures, they must be irradiated by solar concentration systems, which collect solar radiation and concentrate it in small areas. The developed conversion modules combine the advantages of photovoltaic technology, the application of which in the solar concentration has proved to be limited due to the high flux of energy, and the solar thermodynamic systems, operating through a high temperature fluid that feeds specific engines, characterized by high efficiency but also by high cost and reduced scalability. The technology proposed by the CNR-ISM and ISTEC allows to exploit the advantages of both technologies: the absence of moving mechanical elements, high conversion efficiency, high operating temperature, compatibility with thermal energy storage, cogeneration and scalability. Elements of further innovation are the ultra-refractory materials developed, which take advantage of ultrafast pulse laser nanostructuring, combined with carbon-based materials in the form of thin films and with the ability of the CNR to be able to functionalize the chemical-physical properties of volume and surface for this specific application.

ISM actively contributes to the European Researchers’ Night
Dissemination of research activities among the “general public” is one of the institutional activities of CNR. One of the events devoted to this purpose is the “European Researchers’ Night” , which takes place in fall. ISM actively contributed to this event this year, too.
At the Area di Ricerca di Tor Vergata, on September 30th (http://www.artov.rm.cnr.it/index.php/20-global-news/83-notte-europea-dei-ricercatori-2016) the STM laboratory was opened to the public, and Stefano Colonna and Fabio Ronci introduced to visitors of all ages the basic concepts of microscopy, the tunnel effect and crystal surfaces. Then the visitors have had the chance to see the microscope in operation on a real experiment.
A new book on “Ultra-High-Density Magnetic Recording: Storage Materials and Media Designs” edited by G. Varvaro and F. Casoli was published
Magnetic recording is presently the leading technology for mass data storage. Its dominant role has been reinforced by the success of cloud computing, which requires huge amounts of data to be stored and managed on a multitude of servers. Nonetheless, the hard-disk storage industry is presently at a crossroad as the current magnetic recording technologies are unable to achieve storage densities beyond 1Tbit/in2.
Pushing the recording density to the terabit regime requires new storage materials, novel recording schemes and media designs in order to solve signal-to-noise ratio, thermal stability and writability issues.
In this book, worldwide experts from university, public research institutions and industry collaborate to illustrate the most recent advances in magnetic recording from the media perspective and to highlight the future prospects of the technology. Theoretical, experimental and technological aspects are covered in a clear and comprehensive way making the book a reference for final year undergraduates, post-graduates and research professionals in the magnetic recording area.
The fundamentals of magnetism and magnetic recording are introduced in the first two Chapters, which pose the basis for a better understanding of the following chapters. Chapters 3 describes the main features of conventional perpendicular recording media, while the most promising technologies and materials for next generation magnetic recording are extensively treated in Chapters 4 to 7. Techniques and protocols for magnetic characterization of perpendicular recording media are illustrated in Chapter 8. Finally, Chapter 9 gives an overview of the emerging classes of magnetic memories.
