First- and Second-Order Thermal Diffuse Scattering (TDS) Intensity in Molecular Crystals: Influence on Crystal Structure Parameters
(International Union of Crystallography, 1985)
First- and second-order thermal diffuse scattering (TDS) intensities are calculated in the long-wave approximation allowing for dispersion (LWD) in monoclinic phenothiazine from polarization vectors and lattice-mode ...

Structure and Molecular Conformation of l-(4-Acetyl-5-methyl-2-furyl)- 1,3-dideoxy-3-nitro-fl-D-xylopyranose
(International Union of Crystallography, 1980)
The crystal structure of C I2HIsNO7 has been determined at room temperature. Crystals are tetragonal, space group P432~2, Z = 8, with a -- 12.039 (1), c = 17.979 (4)A. 1304 observed reflexions contributed to the ...

Plastic deformation of CoO single crystals
(EDP Sciences, 1980)
Constant strain rate compressions along < 001 > have been performed on CoO single crystals (ε ∼ 6 x 10-5 s-1). Yield stresses and work hardening rates have been measured between 77 K and 1 400 K; CoO is very strong when ...

Multiple steady states on an adsorbent surface
(American Institute of Physics Publising LLC, 1986)
The occurrence of multiple steady states in a system formed by monomers adsorbed on a lattice, with attractive interaction between nearest adatoms, is demonstrated. This fact causes hysteresis in the adsorption-desorption ...
