A thin melt film forms locally at temperatures above the crystallite
melting temperature (semicrystalline thermoplastics) or above the softening temperature (amorphous thermoplastics) (Fig.
The consensus of opinion is that modern day players are not necessarily better than their predecessors, but that the introduction of crystallite
balls and better cloths has seen more consistent scoring.
We will employ specifically tailored molecules designed to leverage both thermodynamic and kinetic aspects of molecular organic semiconductor systems to direct and control crystalline packing, promote crystallite
nucleation, compatibilize disparate phases, and plasticize inelastic materials.
Scherer method is used for calculating the crystallite
size of samples.
s] is the crystallite
size in nanometer, e is the wave length of x-ray beam, a is the broadening of diffraction line at half of its maximum intensity in radians, and [theta] is the Bragg's diffraction angle ([degrees]).
The material is Celanese's new Fortron ICE (Improved Crystallization Evolution) PPS, which is designed to crystallize at higher temperature than standard PPS, resulting in faster and more complete crystallization at lower temperatures and a finer, more uniform crystallite
As the dimension of the Si crystallite
shrinks to nm size, the band gap increases.
However, in most application fields, high-molecular-weight PLA with good thermal resistance is required [17, 19], Numerous efforts have been made on the synthesis of stereoblock poly (lactic acid) (sb-PLA), which will form more stable stereocomplex crystallite
of high-molecular-weight PLA [14, 20-22],
Where D is crystallite
size, [lambda] is wavelength of used ray, [beta] is peak wide in half of the most intensity and [theta] is Bragg angle.
It is possible to collect data on the full range of crystalline-amorphous ratio, phase analysis and crystallite
size determination only, recording without moving the detector.
Van Citters developed angular extrusion, a solid state process, for forming these materials, resulting in high crystallinity by small crystallite
The average surface area and crystallite
sizes of the soils collected from the oil spill sites are relatively higher than the samples obtained from the deep water locations.
