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/
Cultural heritage buildings and artefacts made of natural stones are subjected to deterioration, due mainly to environmental (chemical, physical, biological) agents or anthropogenic pollutants. These lead to the degradation of the stone, compromising its aesthetic appearance but also its physical integrity. Many products have been developed and used to hinder the effects of decay agents or to restore the stone material.
An innovative and very promising strategy to prevent building materials from soiling and biofouling seems to be the use of TiO2 nanocoatings, because of their ability to photo-decompose pollutants under UV irradiation, their durability and affordable costs.
TiO2-based nanocoatings have been widely applied on many stone materials such as marbles, travertines, dolostones and limestones; however, the efficiency of these coatings in such applications is still debated.
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.
New metallic materials or composites are studied and developed.
A unique combination of melting furnaces and metal working facilities (rolling, forging, drawing) allows laboratory-sized or small-sized production for subsequent testing or use in special application.
Numerous materials have been produced and characterised, among which titanium alloys, copper based foams, aluminium based composites, shape memory alloys, refractory alloys, precious metals, and biodegradable metals.
The research activity is articulated along three complementary lines:
- Synthesis and characterization of inorganic nanosystems (thin films, nanopowders) through liquid phase soft-chemical approaches
- Functionalization of nanostructures with molecules and metal complexes through chemical grafting and/or embedding
- Self-assembly and organization of coordination driven metallo-supramolecular architectures
