“…Very probably these are the molecular oxide ions O − 2 (superoxide) and O + 2 (dioxygenyl). Both ions are very stable and exist in solid state compounds where they exhibit molecular magnetism at low temperatures [22]. It is well known that free electrons associate very quickly with O 2 molecules (e.g.…”

Terrestrial solar irradiance data of the Smithsonian Astrophysical Observatory from 1905 to 1954 and of Mauna Loa Observatory from 1958 to 2008 are analyzed. The analysis shows that, with changing solar activity, the atmosphere modifies the solar irradiance on the percentage level, in all likelihood via cosmic ray intensity variations produced by the active sun. The analysis strongly suggests that cosmic rays cause a large part of the atmospheric aerosols. These aerosols show specific absorption and scattering properties due to an inner structure of hydrated ionic centers, most probably of O − 2 and O + 2 produced by the cosmic rays.

“…These temperatures are somewhat too small compared with the experimental values for complete disintegration of ca. 780°C for BaO and 400°C for SrO obtained from DTA/TG measurements (13,56). If we use the HF#corr value for E 0 for BaO , which is 18.4 kJ/mol larger than the DFT value, then we calculate ¹ "755°C (1028 K) and obtain a good agreement with the temperatures from DFT/TG measurements.…”

“…As for the case of CaO , it has not proved possible to prepare MgO in a pure form, with all samples again containing water and/or hydrogen peroxide from the preparation procedure (9,12). Moreover, the question of whether water and/or hydrogen peroxide is included as part of the crystal structure or only physically adsorbed is not easy to decide partly because only powder data are available for this material (13). It is also uncertain as to whether the presence of water and/or hydrogen peroxide is essential for the stabilization of the crystal structure of MgO or whether it should be possible in principle to prepare the pure material.…”

“…To further extend the compositional range of simple metal diazenides, we turned to the investigation of the thermal decomposition of alkali azides under extreme conditions. With respect to the observation that peroxides M 2 O 2 and hyperoxides MO 2 are more stable with the heavier alkali metals (M = K, Rb, and Cs), [8][9][10] we initially targeted synthesis of diazenides in combination with these elements. Surprisingly, we were ultimately successful with the synthesis of a diazenide of the lightest alkali metal, Li 2 N 2 .…”
