The effects of composition on crystallization behavior, crystal transformation, and morphology of crystalline/crystalline PP/PB-1 blends are complicated.
Different phase symmetries including the rhombohedral, tetragonal and monoclinic are found in these crystals, indicating that the composition of the crystals is close to the morphotropic phase boundary (MPB) region.
For melt-crystallized samples, the composition of the crystals is very close to stoichiometric, thereby supporting the notion, for example, that VOH and E residues may act as interstitial- or vacancy-type defects in the polyethylene or poly vinyl alcohol) lattices, respectively.
The chemical composition of the crystals was confirmed by energy-dispersive X-ray spectroscopy, and the structure was determined using single-crystal X-ray diffraction.
However, the composition of the crystals is still unknown.
The chemical composition of the crystals and the degradation layer formed on the magnesium's surface can also explain the better attachment of the cells to these structures.
The controlled fabrication of CaP materials draws great interest because the size, shape and composition of CaP crystals play critical roles in biological response.
We attempted to modify the composition of the crystals through aliovalent co-doping by Ba, Ca, Hf, Sr, Zn and Zr.
The composition of the crystals was not investigated.
The nonphysiological synthesis and composition of these crystals constrain the physiological relevance and utility of the insights that they provide.
