(4) Crystal engineering design techniques are widely used in pharmaceutical industries to modify primary (e.g., particle size, shape,
crystal habit, crystal form, density, porosity, dust generation) as well as secondary (e.g., flowability, compressibility, compatibility, consolidation, reduced adhesion of formulation to the processing equipment, reduction in air entrapment during processing) properties of pharmaceuticals.
One important note some
crystal habit modifier and surfactants may be present in oil layer as well, usually under 1 mL if present.
The
crystal habit according to the short, intermediate and long axes for amphibole was 1:1.5:3 (Modjarrad, 2015a) and for plagioclase, was 1:1.5:1.5 (Higgins, 2002), based on manual measurements of the images, which are similar to data for prismatic crystals used by Morgan and Jerram (2006).
8, where each pixel is 0.334 [mm.sup.2]) illustrate the advancement of filamentous needle
crystal habit structures overnight, clearly showing the evolution of six individual frost flowers from their originating nodule positions (see Fig.
The goal of this study is, through ultrastructural analysis, to identify the primary CaC[O.sub.3] mineralogy and
crystal habit of some of problematic reef builders proliferating around the Mulde Event in Baltica, and thus gain an insight into whether their calcareous walls were formed through biologically controlled precipitation or by microbial mediation.
The
crystal habit of an unprocessed drug, for example, is known to be affected by many factors, including the kinetics of crystal growth, level of impurities, crystallization process parameters and the solvent and/or antisolvent used in the crystallization.
cygnea was carried out to determine the normal pattern of the microstructure and
crystal habit from the ventral margin of the shell to the interior shell surface near the pallial line.
We did find one
crystal habit in microscopic crystals that was not present in hand specimens.
John Torgesen (1948-1972) Growth and purification of large single crystals from aqueous solutions under extreme control of temperature and temperature gradients, measurement of impurity retention and resulting
crystal habit modifications.
Thus, formation of polymorphs was overruled because
crystal habit will not change the melting point.
