Effect of Ordering on Spinodal Decomposition of Liquid-Crystal/Polymer Mixtures

Partially phase-separated liquid-crystal/polymer dispersions display highly fibrillar domain morphologies that are dramatically different from the typical structures found in isotropic mixtures. To explain this, we numerically explore the coupling between phase ordering and phase separation kinetics in model two-dimensional fluid mixtures phase separating into a nematic phase, rich in liquid crystal, coexisting with an isotropic phase, rich in polymer. We find that phase ordering can lead to fibrillar networks of the minority polymer-rich phase

Photoluminescence of oxygen dominated phosphors

The mechanism of fluorescence in (a) CaW04, (b) Zn2Si04:Mn, (c) 3.5 MgO + 0.5 MgF2 + GeO, : Mn, and (dl 3Ca,(P04), Ca(F, C1)2:Sb3+, Mn2+ under excitation by shortwave ultraviolet is explained by the electronic transitions involved in the activators. To get a daylight phosphor conforming to 6500"K, a blending of a sb3+ activated halophosphate blue phosphor and a Sb3+ and Mn2+ activated warmwhite phosphor is essential and the successful preparation of the same is presente
