Thermodynamic calculations indicate that molybdenum particles reinforced copper-matrix composite can be fabricated in CuO-Al-MoO3 powder system. Thermit reaction and self-propagation high-temperature synthesis (SHS) were applied to prepare samples. Then the phases, structure morphologies and properties were studied through the instruments of XRD, SEM and microhardness tester. The results show that nanocrystals are formed in Cu matrix and molybdenum particles are dispersive distributed in Cu matrix. The microhardness of 5﹪Mo-Cu nanocomposite is 110HV，and the relative electric conductivity is 58.6﹪IACS.

High Electric Conductivity

Abstract As one of the conductive ink materials with high electric conductivity, elemental copper (Cu) based nanocrystals promise for printable electronics. Here, single crystalline Cu nanoplates were synthesized using a facile hydrothermal method. Size engineering of Cu nanoplates can be rationalized by using the LaMer model and the versatile Cu conductive ink materials are suitable for different printing technologies. The printed Cu traces show high electric conductivity of 6 MS/m, exhibiting electro-magnetic interference shielding efficiency value of 75 dB at an average thicknesses of 11 μm. Together with flexible alumina ceramic aerogel substrates, it kept 87% conductivity at the environmental temperature of 400 ℃, demonstrating the potential of Cu conductive ink for high-temperature printable electronics applications.

Abstract. Lithium-manganese spinels obtained by sol-gel method were studied by XRD, impedance spectroscopy, electric conductivity and thermogravimetric analysis (TGA). Heating of low-temperature spinels up to 630° C leads to the formation of spinels with lattice constants close to stoichiometric high-temperature spinels, which exhibit no phase transition around room temperature and have good electric conductivity.
