As often teachers underline, textbooks are an essential tool and a good point of reference for students, but they are not sufficient to teach chemistry in a significant way. For this reason, teachers often look for sources from which to get updates on scientific knowledge, but also on teaching methodologies and on successful experiences. These...

Raman spectra of cubic Sc2O3, Y2O3 and C-type rare earth oxides are presented. Cubic Nd2O3 is prepared by thermal decomposition of its hydroxide. The decomposition mechanism happens in two steps. At the end of this process cubic Nd2O3 form. All Raman spectra are characterised by the presence of a very strong band in the range 320–420 cm−1,...

The acquisition of knowledge proceeds through a forced passage: the experimental observation. This work deals with physical-chemical concepts related to the flame through the development of practical and thepretical activities concerning the light-matter interaction and the heat exchanges. The target is constituted by a second class of a...

By studying the influence of Hg stoichiometry on the Tc of the superconducting compound HgBa2CuO4-δ (Hg-1201), we have started to re-examine the composition of the only intermediate phase reported in the Cu-Hg diagram. The oxidation of this phase could lead to a very unstable Cu-Hg oxide to employ with BaO2 in the synthesis of superconducting...

The Cu–Hg system has been re-examined focusing on the only intermediate phase. Our results are not in agreement with the accepted literature data: both decomposition temperature and composition have been discussed. The structural determination performed on a single crystal is already in progress and, although it shows a trigonal cell, the...
