While she does not run laboratories or grants, she is working with colleagues and active in research, currently in the field of spinodal decomposition of blends of polymeric materials.
Its physical applications have been extended to many areas of scientific fields such as spinodal decomposition [1,3], diblock copolymer [4-6], image inpainting [7], multiphase fluid flows [8-10], microstructures with elastic inhomogeneity [11, 12], tumor growth simulation [13,14], and topology optimization [15, 16].
The phase diagram so obtained is found to follow an LCST behavior, a similar result has been reported for DGEBA-poly([epsilon]-caprolactone) blends [22], Thus, we can envisage different situations: (i) when the amount of PTT is low, spinodal decomposition occurs, which is represented by Region (a) and (ii) when the amount of PTT is high (above 30 wt%) an increase in viscosity of the matrix retards the diffusion of DGEBA monomers.
However it is important to note that the alphaalph[alpha]' spinodal decomposition occurring in the ironchromium-based ferrite is responsible for this aging susceptibility.
The alkali borosilicate material is formed using a proprietary process that involves phase separation via spinodal decomposition, which causes the borate-rich phase to orient from the outside to the inside of the shell and then leach out.
Built with an alkali borosilicate, the composition is phase-separated via spinodal decomposition.
Among the topics are spinodal decomposition versus nucleation and growth, using the lattice Boltzmann algorithm, to explore phase ordering in fluids, aging in domain growth, morphological transitions in microphase-separated diblock copolymers, and the dynamics of phase transitions in solids.
The organized pattern is similar to the so-called bicontinuous spinodal decomposition structures, which are usually found during the phase separation in the systems of multi-components.
Wiltzius studies a related phenomenon called spinodal decomposition, for which researchers developed convincing laboratory models only a decade ago.
Shear could influence solubility during mixing of simple blends, but the nodular nature of the phases and phase size is more consistent with a shear dispersion mechanism than a spinodal decomposition or crystallization on cooling from a thermodynamically soluble system.
By establishing the theory of three-dimensional spinodal decomposition, Dr.
In contrast, spinodal decomposition was reported to generate a highly interconnected structure to form a crystallized state [12].
