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.

Marco Musiani, research director at ICMATE CNR Padova, has been appointed Honorary Member of the International Society of Electrochemistry (ISE) by the Executive Committee of the Society, which has approved a proposal of the seven ISE Presidents in charge from 2005 to 2018. ISE Honorary Members are appointed primarily in recognition of their contribution to the Society. The ISE By-Laws limit to ten their maximum number, at any time.
The definition of the authenticity of artworks has undergone a slow process of development: with time, connoisseurship — the traditional practice of attributing detailed artistic identities to works of art on the basis of a comparative analysis of stylistic and formal components — has lost its position of technical leadership. In fact, currently, trust in the expert eye is increasingly subjected to the “objective” outcomes ensured by new and more rigorous techniques of scientific analysis of materials. However, this approach risks being somewhat reductive and incomplete.
THIS WEEK'S HIGHLIGHTS
3D catalytic systems obtained through the deposition of Pd, Pt or Rh nanoparticles onto Ni or Fe-Cr-Al alloy foams are effective toward both electrochemical processes and gas phase oxidation reactions.
Calcium alkoxides for the conservation of stone and woodhistorical artifacts
Despite the great number of treatments that have been used and are still in use to cope the problem of deterioration of lime-based historical artifacts, no real solution has been found yet. Neither the organic polymers nor inorganic treatments have demonstrated to guarantee satisfying performances. If the former suffer from incompatibility with the substrate and long-term irreversibility (due to physico-chemical modification of the polymer itself), the latter, though more compatible, show the drawback of scarce solubility. To overcome this problem, micro-and nano-dispersions of calcium hydroxide in alcohol have recently also been prepared and tested.
