Continuous Protein Crystallization in Mixed-Suspension Mixed-Product-Removal Crystallizers

Crystal Growth & Design, 2021
The metastable needlelike form of lysozyme can be obtained from continuous crystallization in mixed-suspension mixed-product-removal (MSMPR) crystallizers for conditions at which the stable tetrago...

Mixed Crystal Deposition

Rheumatic Disease Clinics of North America, 1988
Mixtures of crystals are found in joint tissues more commonly than would be expected by chance. In osteoarthritic joints, for example, mixtures of different calcium salts are more common than any one type of crystal alone. This is partly explained by the predisposing factors and mechanisms of crystal formation, many of which are not salt specific.

Study on the mixed crystals

Journal of Physics: Condensed Matter, 1997
A study on the mixed crystals of formula (1>x>0) has been carried out, using thermal analyses and x-ray diffraction on powder and single-crystal samples at different temperatures. It is shown that mixed crystals with have a transition from the paraelectric to the ferroelectric phase; decreases as the value of x increases.

Phonons in mixed crystals

Zeitschrift f�r Physik B Condensed Matter and Quanta, 1976
A concept is presented which gives qualitative information concerning the phonon behaviour of ionic mixed crystalsAB1−xCx at certain symmetry points on the zone boundary and consequently through the zone to the center. The model assumes that the end-member phonons and the impurity-modes ofAB:C andAC:B are known and uses the assumption that mixed ...

Mixing and crystallization in suspensions

Chemical Engineering Science, 2000
The influence of mixing on suspension crystallization is described from the starting point of a fully mixed system with mixed product withdrawal. An imperfect suspension, caused by less intensive mixing, is then introduced and the effects of imperfect suspension on suspension density distribution along the height and on crystal size distribution in the

Mixing in continuous crystallizers

AIChE Journal, 1986
AbstractThe review is concerned primarily with some aspects of mixing in continuous crystallizers and recognizes the central importance of the interplay between the mixing and crystallization (or precipitation) processes in the design and performance evaluation of industrial crystallizers.

Phonons in mixed crystals

Journal of Physics: Condensed Matter, 1991
The simple example of phonons in a linear chain of atoms with substitutional disorder is reconsidered in order to determine the rearrangements of acoustic and localized mode branches with increasing concentration of light impurities. The coherent-potential approximation cannot be applies successfully to this problem.

Mixed Crystal Formation in High Polymers

Nature, 1947
AN interpolymer of ethylene and vinyl alcohol (prepared by co-polymerization of vinyl acetate and ethylene followed by hydrolysis1) has been found to give a crystalline X-ray diffraction pattern different from those of either polythene or polyvinyl alcohol. The fibre repeat distance is 2.5 A., corresponding to a single hydrocarbon chain zigzag.
