High-temperature thermal expansion of six metallic elements measured by dilatation method and X-ray diffraction

Microemulsion Approach to Nanocontainers and Its Variability in Composition and Filling

“…With a synthesis performed at ambient temperature, this finding is quite surprising, expecially in the case of the oxides, which are normally known to crystallize at elevated temperatures (>200 8C). [12] The observed highly ordered lattice fringes for all compounds result in d-values that are in good agreement with reference data: 2.0 Å [Au: (200) with 2.04 Å ]; [13] 2.0 Å [CuS/ covellite: (110) with 1.90 Å ]; [14] 3.2 Å [g-AlO(OH)/boehmite: (120) with 3.17 Å ]; [15] and 3.3 Å [SnO 2 /cassiterite: (110) with 3.35 Å ]. [16] Particle size, degree of agglomeration, and phase purity and crystallinity of all materials presented are also confirmed by dynamic light scattering, powder and electron diffraction.…”

Microstructure analysis of spherical silicon solar cells with SnOx:Fy layers

“…Lattice constants of the annealed SnOx:Fy layers increased, and were estimated to be a = 0.4745 nm and c = 0.3190 nm. For the SnOx:Fy layers with Ag-paste, diffraction peaks corresponding to not only SnO2 crystal [20] but also Ag crystal [21] were observed, while Ag-based oxide peaks such as AgO and Ag2O were not observed. Lattice constants of the Ag-pasted SnOx:Fy layers were larger than those of the as-prepared SnOx:Fy layers since the 110 and 101 diffraction peaks shifted to lower diffraction angle, as shown in Fig.…”

Structure and thermal expansion of liquid bismuth

“…Traditionally, most attention in the study of thermal expansion has been paid to solid materials with a crystalline structure in which a periodic atomic arrangement allowed developing a theory and using it for the interpretation of experimental data [1]. Contrary to crystalline materials, amorphous solids and liquids have a short range order only and for this reason the theoretical background for their thermal expansion is significantly less * E-mail: sihor@ukr.net developed.…”
