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.

During the 6th Global Conference on Materials Science and Engineering (CMSE 2017),
organized by Wuhan Advance Materials Society, held in Beijing in October 24th-27th,
the oral contribution (Invited lecture) Antifouling amphiphobic coatings for protection in sea environment,
presented by Michele Ferrari
has been awarded as best oral presentation in Surface and Coatings Technology session.
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
Dust in fusion devices is still an open issue from the point of view of plasma operations and safety and due to its high fuel retention capability and mobility.
Thus, dust behaviour in such environments needs to be understood.
The analysis of this behaviour is both theoretical, focused on dust mobilization conditions, and experimental, aiming at mimicking these conditions.
Alloy design method which consists of theoretical analysis and experimental examination has been /is applied to develop three class of alloy systems, i.e. new Pb-free solders, alloy catalysts and biomedical alloys by using nanoparticles (NPs).
Biomedical fabrics with antibacterial or, more generally, therapeutic purposes are a challenging manufacturing task in textile industries. From one side, the fabric itself hosts the bacteria acting as a medium between the human organism and the microorganisms; on the other hand, it is regarded as a well assessed tool for drug delivery in contact of skin for external applications.
