WebMay 24, 2024 · C-type starches with different proportions of A- and B-type crystallinities have different intensities and crystallinities of X-ray diffraction peaks. In this study, the intensities and crystallinities of X-ray diffraction peaks, molecular components and heat properties of C-type starches were investigated in seven sweet potato varieties, and ...
WebCrystallinity can be accurately measured by X-ray diffraction and less accurately but simply by specific gravity. The properties of PCTFE vary with the degree of crystallinity. Table … WebAs shown in Figure 3, the characteristic plot of ln φ versus ln t of BPC 0 at various relative crystallinities is presented according to Equation (9). Each crystallization stage was fitted with a straight line, and the R 2 value was greater than 0.97. This result demonstrated that this model is applicable for describing the nonisothermal ...
WebCrystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In an ideal gas, the relative positions of the atoms or molecules are completely random.
