Change of the Shape of a Chemical Vortex Due To a Local Disturbance

Change of the Shape of a Chemical Vortex Due To a Local Disturbance. Aliev, Rubin R.; Davydov, Vasily A.; Ohmori, Takao; Nakaiwa, Masaru; Yamaguchi, Tomohiko (National Institute of Materials and Chemical Research, Tsukuba 305, Japan). Journal of Physical Chemistry A, 101(7), 1313-1316 (English) 1997 American Chemical Society. 7664-93-9 and 7789-38-0 are cas registry numbers. These chemicals are also mentioned in this article. CODEN: JPCAFH. ISSN: 1089-5639. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) Section cross-reference(s): 22, 65, 74 We studied the dynamics of a chem. vortex whose core was disturbed by visible light. The obsd. sharp change of the shape of the vortex and the unfolding increase in the vortex wavelength proved to be tightly related to a transformation of trigger waves to phase waves. Anal. estns. and direct measurements show that the shape of the vortex is well-fitted by a logarithmic spiral. The results of expts. and of computer simulations are in a good agreement. .

An x-ray diffraction study of the size effect on a crystalline solid solution of sodium halates

An x-ray diffraction study of the size effect on a crystalline solid solution of sodium halates. Raja, C. Sanjeevi; Mohanlal, S. K.; Chandrasekaran, K. 7775-09-9 and 7789-38-0 are also occured in this study. S. (Sch. Phys., Madurai Kamaraj Univ., Madurai 625021, India). Z. Kristallogr., 166(1-2), 121-7 (English) 1984. CODEN: ZEKRDZ. ISSN: 0044-2968. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) Na(ClO3)0.7(BrO3)0.3 is cubic, space group P213, with a 6.630(2) ?. The structure was refined by full-matrix least-squares to a final R = 0.057; at. coordinates are given. The size effect distortion is less appreciable in the halate system compared to the reported work on cryst. solid solns. of simple structures. However, a small over-all static shift for the halogen atom alone is obsd. .
