Crystallization of the matrix

The tissue sections must be washed with organic solvents when the detection targets include peptides and proteins. Washing with organic solvents promotes the ionization of peptides and proteins mainly by removing phospholipids from the sections.14 Washing also flushes out salts that could interfere with the crystallization of the matrix. 

The energy equation, with temperature varying as a function of radial, circumferential, and axial position and time, is the basis of the thermochemical submodel. The energy absorbed or released during the cure or crystallization of the matrix is included in the energy balance. The appropriate multidimensional energy equation is Equation 13.1,... 

Several characteristics of the matrix and filler-matrix interphase are involved in material toughening. These include the particle size of filler, interfacial adhesion, filler concentration (already discussed), filler surface composition, the crystallization of the matrix, shell thickness, stress whitening, and strain hardening. 

In immiscible blends, the phases are separated in the molten state, before crystallization of the matrix starts. The dispersed amorphous phase is assumed to be homogeneously distributed in the melt in droplet-like domains.

For most commonly studied polymer blends, crystallization of the matrix occurs in the presence of a molten dispersed phase. The crystallization behavior of the continuous phase can be compared to that found for crystalline/amorphous blend systems in which the dispersed amorphous phase was in the molten state.

We keep the laboratory temperature at approximately at 21 °C (70 °F). It may also be helpful if you control the humidity in the laboratory because the rate of co-crystallization of the matrix/analyte may be affected by the humidity that will affect the quality of the spectrum. 

Among the mass spectrometric techniques, MALDI-MS is the least susceptible to the presence of salts and detergents in the sample. However, high levels of contaminant may lead to poor crystalization of the matrix and consequently, a... 

In the case of the crystallization of the matrix in the presence of already solidified or crystallizing particles, migration of nuclei still can play an important role. However, several other phenomena have to be taken into account. First of all, the soUdihed domains can act as efficient nucleators. Furthermore, retarded crystallization of finely dispersed droplets can nucleate the matrix and leads to coincident crystalhzation of both phases. Finally, it has been reported that epitaxial crystallization at the interfaces sporadically occins. All these phenomena lead to an increased heterogeneous nucleation of the matrix phase. 

The results of research described above prove univocally that the presence of lignocellulosic material in polymeric composites influences the crystallization process, altering the kinetic parameters, such as induction time, degree of crystallinity, conversion degree, etc., and characteristic temperatures. Using modification of the filler is not without the effect on crystallization of the matrix. An interesting phenomenon that has not been explained completely so far is the transcrystallization. Both the formation of transcrystallization and its effect on mechanical properties remain a disputable question among researchers. 

Secondly, the wetting problems of the dispersed fibrous LCP domains to the isotropic matrix phase are less sraious. Thirdly, in some cases LX3P imparts a nucleating effect to the crystallization of the matrix phase (6,7). Fourthly, the dimensional stability of the fabricated products may be greatly improved because of the low thermal expemsion coefficient of LCP. Finally, the products based on the insitu composite are reusable, which is helpful to solve the ecological and environmental problems. 

As we have seen some nanoparticles are able to direct the crystallization of the matrix material. Mitchell et al. (2015) have used time-resolving x-ray scattering techniques at a synchrotron beam line to follow the structural evolution in a...
