Oriented Crystallization of Vaterite in Collagenous Matrices
Chemistry - A European Journal, 1998The influence of high super- saturation on kinetic control and the importance of the polypeptide structure in the crystallization of calcium carbo- nate polymorphs were studied in cross- linked gelatin films containing high concentrations of the polypeptides poly-l-aspartate and poly-l-glutamate.

Orientation of Single Crystals
1974The orientation of single crystals involves two basic tasks: the determining an unknown orientation and setting a sample in desired orientation. In order to explain our method we proceed in the following manner: First we describe the experimental setup for taking pictures of Laue back-reflection patterns and the conventional back-reflection Laue method

Oriented crystallization of inorganic salts in collagen
Experientia, 1955Wenn gestreckte Kollagenfasern in einer alkalischen Losung gewisser anorganischer Salze gelassen und dann getrocknet werden, so kristallisieren die Salze mit einer ihrer Achsen in paralleler Orientierung zur Faserachse. Die Periode parallel dieser Achse liegt zwischen 3,2 und 3,75 A oder einem Vielfachen dieser Werte.

A crystal-orienting device for ESR studies
Journal of Physics E: Scientific Instruments, 1977A description is given of a device which allows the precise orientation of a single crystal in any given direction with respect to the static magnetic field. It particularly facilitates the ESR analysis as it gives the angular dependence of the ESR signals in the principal planes.

Colloid and Polymer Science, 1978
A general orientation equation for rigid particles embedded in a continuum has been derived. The equation includes hydrodynamic, thermodynamic, diffusional and kinetic terms, corresponding to physically different orientation mechanisms. Some special solutions of the general equation are presented, and discussed conditions under which the general ...

Molecular Orientation in Liquid Crystal Elastomers
Macromolecules, 2005Free-standing and confined anisotropic liquid crystal elastomer films of various thicknesses have been prepared using mesogens with laterally affixed polymerizable side chains. Textures have been studied by microscopy, whereas molecular orienation of the mesogen groups has been investigated by polarized FTIR and Raman spectroscopies considering an ...

Orientation crystallization of polymers
Fibre Chemistry, 1978The important point made in the last section was the discovery in the systems of structures of the usual folded kind and of morphological elements which consist of orientation-crystallized and probably straightened macromolecules the presence of which can be predicted from the results of a thermodynamic analysis.

Woodpile photonic crystal of various crystal orientations
SPIE Proceedings, 2011Three-dimensional woodpile photonic crystals with a variety of crystal orientations and surfaces, including (110), (001), (100) and (010) planes, are fabricated in GaAs and silicon with the multi-directional etching method. The optical properties of the fabricated woodpile photonic crystals are characterized via reflectance spectra measurement. High
