AbstractThe character and the magnitude of magnetic interaction in 1‐D stacks of mixed molecular radical crystals (MMRCs) and mixed molecular ion radical crystals (MMIRCs) of alternant aromatic hydrocarbons have already been studied theoretically. In this work nonalternant 1‐D stacks built of π‐electronic subunits are considered. Some of the elementary

Polymerization in mixed crystals
Journal of Materials Science, 1980Suitably substituted diacetylenes can be co-crystallized to form substitutional solid solutions. By solid state polymerization of these mixed crystals macroscopic single crystals of statistical copolymers can be obtained. The co-crystallization is described and the influence of crystal composition on structure and reactivity in the solid state is ...

Three crystals of 2-cyanoethyl cobaloxime complexes with 3-chloropyridine, 3-bromopyridine and 3-methylpyridine as axial base ligands are isostructural to one another. Three mixed crystals were formed between the pairs: (3-bromopyridine)(2-cyanoethyl)cobaloxime–(2-cyanoethyl)(3-methylpyridine)cobaloxime(0.45/0.55);(3-chloropyridine)(2-cyanoethyl ...

Mixing and crystallization in suspensions
Chemical Engineering Science, 2000The 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

Elementary Excitations of Isotope: Mixed Crystals
Physics Reports, 2005This book develops and describes the isotope effect in the low-dimensional structures (down to 3–10 A). Without assuming prior knowledge of quantum physics, present book provides a unifying framework for the basic ideas needed to understand the recent developments in the nanoscience.

Raman Scattering from Mixed Crystals
1969A theory for the optical properties (Raman scattering or I. R. absorption) of crystals containing a small but finite concentration of impurities will be described. One result of this theory will be a qualitative understanding of the various experimental results that have been obtained for different mixed crystals at much larger concentrations.

The mixed suspension, mixed product removal crystallizer as a concept in crystallizer design
AIChE Journal, 1965AbstractSimultaneous population and mass balances have been solved together with a generalized form of nucleation‐growth rate kinetics to obtain the form of crystal size distribution (CSD) for several idealized modes of crystallizer operation, including seed crystal removal, product classification, arbitrary solids concentration, and staged vessels ...
