Crystal Structure and Luminescence Properties of the First Hydride Oxide Chloride with Divalent Europium: LiEu2HOCl2

Abstract: The mixed-anionic hydride oxide chloride LiEu2HOCl2 with divalent europium was synthesized by the reduction of Eu2O3 with LiH in a LiCl flux at 750 °C for 4 days in silica-jacketed niobium capsules. According to structure determination by single-crystal X-ray diffraction the yellow compound crystallizes in the orthorhombic space group Cmcm (a = 1492.30(11) pm, b = 570.12(4) pm, c = 1143.71(8) pm, Z = 8) with a crystal structure closely related to that one of the quaternary hydride oxide LiLa2HO3 and the hydride nitride LiSr2H2N. On the other hand it can also be derived from the PbFCl-type structure of EuHCl showing astonishingly short Eu2+∙∙∙Eu2+ contacts of 326 and 329 pm. Both crystallographically different Eu2+ cations have nine anionic neighbors, while all other ions (Li+, H-, O2- and Cl-) reside in six-membered coordination spheres. LiEu2OCl2H exhibits a bright yellow luminescence with an emission maximum at 581 nm upon excitation at 440 nm.

Organisational culture differences and market orientation: an exploratory study of barriers to university-industry relationships

Abstract: Despite the growing importance of universityindustry relationships (UIR) and the high proportion of such linkages failing, little is known on barriers to the formation and development of these relationships. This exploratory study aims at exploring such barriers. Organisational culture difference (OCD), such as differences in motivation, time orientation and market orientation (MO), were found to negatively effect UIR formation and development. Negative perceptions of universities' MO clearly emerged from the data. Indeed, universities' MO should be considered as a broad concept based on all value creation factors, not just 'business skills'. Finally, internal structures, bureaucracy and academics' individualistic way of working were identified as further factors potentially hindering universityindustry relationships. Managerial implications involve recognising the role of individuals, their passion and experience, in overcoming the barriers identified in this study.

Low temperature synthesis of calcium cobaltites in a solid state reaction

Abstract: This paper presents synthesis of calcium cobaltites of the nominal composition of Ca3Co4O9 prepared by the solid state reaction. The reaction between CaCO3 and Co3O4 was investigated at 700–900 °C during 20 h and at 800 °C during 2–30 h. Mass changes, phase composition and Co+3, Co+4 content were examined. Stability of the calcined specimens was tested by DTA/TG. It was found that two phases: Ca3Co4O9 and Ca3Co2O6 were present as a result of calcinations above 800 °C. On the other hand, the temperature of 750 °C was too low for calcium cobaltites to be synthesized. Mono-phase material with Ca3Co4O9 phase was obtained after calcinations at 800 °C but non-stoichiometry of the compound and its relation to the calcinations time were found. Once synthesized, the compound was stable up to 900 °C.
