High performance Li-Ion batteries. The ICMATE Institute, working in collaboration with the Helmholtz Institute Ulm (Germany), has provided an original contribution to this strategic goal. In the ICMATE labs, researcher have developed a porous Cu-Zn alloy suitable for use in Li-Ion batteries. The colleagues of the German Institute have demonstrated that electrodes of this material show outstanding low temperature performances, far superior to those of conventional materials like graphite.

In the field of conservation there is a continuous challenge to develop new and sustainable treatments, which have no or a minimal impact on the microstructure of the object. In the conservation of photographs, removal of corrosion products from the surface is a delicate issue; conservators/restorers should choose the most suitable method.

THIS WEEK'S HIGHLIGHTS
The main activities of Lecco unit of CNR – ICMATE on the subject of thermoelectricity are the material synthesis and the development of new material processing techniques. The development of the activity starts from the synthesis of materials with different techniques ranging from traditional melting to powder metallurgy (mechanical alloying, solid state reactions), going down to powder sintering and material transformation using techniques typical of metallurgy (extrusion, rolling, wiring,…) conveniently set to achieve improved properties in the final samples.
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.
The activity is focused on the interfacial properties of complex systems in presence of surfactants and solid micro-nanoparticles.
