Crystal breakage is a function of the solids concentration in the system as well as the shear rate. As scale and mixing conditions change - solids concentration and shear rate gradients may become important, meaning more or less breakage could occur as a crystallization process is scaled ...
Among them,nis the Avrami index, which reflects the geometric information of nucleation and crystal growth, andkis the crystallization rate constant[118]. Although the Avrami equation can also be used in the non-isothermalcrystallization processof polymers, the physical meaning of the values ofnand...
In some instances the bulk chemistry of the rock is markedly affected. The hydrothermal alterations favour development of phases such as albite, carbonates, chlorites, clay minerals, epidotes, iron oxides, micas, silica minerals, talc, and zeolites, and many of them are accompanied by gross ...
Figure 2 shows that the given material is highly soluble in Solvent A, meaning more material can be crystallized from a given volume of solvent. Conversely, the given material has a low solubility in Solvent C across all temperatures, potentially making it a good anti-solvent for this material...
Now from my limited understanding it seems that the person that wrote this has mi-used the word 'crystallization', instead meaning to refer to the pulverisation to dust of something. I assume that it is possible to pulverise something to dust so..., under what circumstances could this be ...
Orthogonal to guided growth of nanoparticle (NP) crystals using DNA or supramolecules, a trace amount of polymeric impurities (<0.1 wt.%) leads to reproducible, rapid growth of 3D NP crystals in solution and on patterned substrates with high yield. Wh
As a result, the rock is either composed of minerals that can be seen only with the aid of a microscope (called aphanitic, from the Greek aphanēs, meaning “invisible”) or contains no minerals at all (in the latter case, the rock is composed of glass, which is a highly viscous ...
nylon 66 and 2.3-3.0 for the blends, meaning that there are no significant changes in the Avrami exponent n for pure nylon 66 and the blends because the small change of the exponent n in the range of 0.2---0.3 is trivial in Avrami analysis. From the results in Figure 3 and Table I...
However, the neutron scattering length of H is negative, while C, N, and O are positive, meaning the presence of hydrogen leads to signal cancellation effects. Fortunately, D has a positive scattering length, and thus the H problem can be circumvented through protein perdeuteration6. Though ...
