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.

69th Annual Meeting of the International Society of Electrochemistry (ISE), Bologna, 2-7 September 2018
Organized by a committee chaired by doctor Marco Musiani, ICMATE CNR, and professor Francesco Paolucci, Bologna University and ICMATE associate, the 69th Annual Meeting of the International Society of Electrochemistry (ISE) has taken place in Bologna, on 2-7 September 2018. The participation of 2033 delegates, from 55 countries, has been the largest in the ISE history.
1st International Conference on Nanofluids (ICNf) and the 2nd European Symposium on Nanofluids (ESNf)
24th – 26th June 2019, Castellon (Spain)
These are a series of international conferences under the auspices of the European Cooperation in Science and Technology (COST) Action - NANOUPTAKE (CA15119, www.nanouptake.eu). Focuses of ICNf 2019 include production and characterization of nanofluids and liquid-based nanocomposites, nanofluid-based heat transfer and storage of thermal energy, as well as industrial applications.
Simona Barison, ICMATE CNR, is a member of the Scientific Committee and will be glad to provide information on the Conference.
Peru has a significant number of constructions of high historical and cultural value distributed along the country. Among these archaeological remains of great significance, there are multiple ‘Huacas’, which are pyramidal earthen constructions often built for sacred or religious purposes. Some of the many existing huacas have been damaged due to exposure to severe natural and anthropogenic hazards.
The selection of the best preservation or intervention strategies of these archaeological earthen constructions is a very challenging process that is often hampered due to the difficulty to define in-situ conditions.
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.
A relevant part of the research activity is focused on the optimization of innovative "wet chemistry" synthesis processes through three general approaches:
- nucleation and growth from solution
A first approach is based on the combination of hydrothermal treatments with oxalates co-precipitation. This approach has been used for the production of nanomaterials with interesting magnetic properties, in particular ferrites and manganites, with crystallite domains with average sizes ranging between 5 and 50 nm.
