3D POROUS Cu–Zn ALLOYS AS ALTERNATIVE ANODE MATERIALS FOR LI-ION BATTERIES WITH SUPERIOR LOW T PERFORMANCE
A joint team between ICMATE CNR Padova and Helmholtz Institute Ulm for Electrochemical Energy Storage has developed a novel class of lithium-ion battery (LIB) anodes based on Zn-rich porous CuxZn1-x intermetallic compounds. The carbon- and binder-free electrodes produced by a cheap and scalable electrodeposition procedure in aqueous media exhibit an extraordinary lithium storage capability at low temperature. These findings pave the way for more efficient, safer and faster charging of LIB-powered vehicles in regions with cold climates.

Special session “Tribute to Paolo Nanni: from synthesis to advanced ceramics”
A special session “Tribute to Paolo Nanni: from synthesis to advanced ceramics” dedicated to the memory of Prof. Paolo Nanni will be held within the framework of the conference CIEC16 - 16th European Inter-Regional Conference on Ceramics (9-11 September 2018, Turin, Italy). Prof. Paolo Nanni was for many years an active and enthusiastic collaborator at the Genoa unit of IENI-CNR and ICMATE-CNR. For further information: http://www.ciec16.polito.it/
Art objects conservation or historical analysis necessitates a thorough knowledge of the materials used by the artist and during the subsequent changes, their chemical composition and determination of their preservation state. In the case of paintings this requires the ability to correctly identify the pigments that were used for creation or later restoration of the artwork. This is a challenging problem, as the applied method should be non-contact, robust for the wide variety of chemical substances used and straightforward in the interpretation. Recently, the hyperspectral imaging has emerged as a promising measuring methodology for this kind of the artwork analysis; the combination of acquiring spectral information and planar (photography-like) pixel arrangement provides a lot of potential for material characterization. While initial studies of hyperspectral imaging application to art objects analysis are encouraging, the difficulties of working with its multidimensional data are acknowledged; in many cases complex algorithms are required to fully utilize its potential.
THIS WEEK'S HIGHLIGHTS
The increasing demand for alternatives to fossil fuels lead scientists to search for new materials to be used as energy vectors. Nowadays, it is generally accepted that hydrogen is the best solution to this issue. One of the reasons why hydrogen is not yet commonly employed in everyday life lies in the lack of a safe, practical and effective method for its storage. A possible solution that meets the above requirements is given by intermetallic hydrides, which can be charged with hydrogen at high-pressure to form stable hydrides, then releasing hydrogen by heating the host intermetallic.
