The crystal structure of (Et2NH2)2SnCl6 (P21/n, Z = 2, a = 9.078(1) Å, b = 10.644(2) Å, c = 9.801(2) Å, β = 93.02(1)°) consists of a monoclinically distorted antifluorite arrangement of Et2NH2+ and SnCl62− ions. The SnCl6 octahedra are linked by hydrogen bonds to form infinite chains separated from one another by the Et groups. The temperature variation of the spectral features in the NH and ND stretching regions points to the existence of a transition in the vicinity of 320 K. The structure of (n-Pr2NH2)3(SnCl6)Cl (P21/c, Z = 4, a = 10.265(4) Å, b = 30.428(4) Å, c = 10.380(2) Å, β = 92.75(3)°) consists of n-Pr2NH2+ cations of three types, SnCl62−, and Cl−. All the ions are interconnected by hydrogen bonds, those to Cl− being of a strength comparable to the strength of the short, linear [Formula: see text] bond in Et3NHCl. Spectroscopic evidence indicates the probable existence of a transition at ~170 K.

ABSTRACTWe report a detailed study using photoluminescence and photoluminescence excitation of MOCVD GaAs grown directly on Si substrates. Temperature variation and selective excitation allow reliable assignment of spectral features. This assignment permits measurements of strain and strain uniformity, identification of impurities, and assessment of general materials quality. In 2–5μm thick layers similar spectra are observed with little variation from substrate character. Most samples show one of the two split valence band features plus defect recombination, always including carbon. Strain uniformity varies widely and correlates with substrate thickness. The range of spectra observed from a variety of samples, and guidelines for interpretation of nonresonantly excited spectra will be discussed.

Abstract Nowadays the facades of newly built buildings have significant glazed surfaces. The solar gains in these buildings can produce discomfort caused by direct solar radiation on the one hand and by the higher indoor air temperature on the other hand. The amplitude of the indoor air temperature variation depends on the glazed area, orientation of the facade and heat storage capacity of the building. This paper presents the results of a simulation, which were made in the Passol Laboratory of University of Debrecen in order to define the internal temperature variation. The simulation proved that the highest amplitudes of the internal temperature are obtained for East orientation of the facade. The upper acceptable limit of the internal air temperature is exceeded for each analyzed orientation: North, South, East, West. Comparing different building structures, according to the obtained results, in case of the heavy structure more cooling hours are obtained, but the energy consumption for cooling is lower.
