Journal ArticleDOI
Modeling of Vinylidene Fluoride Heterogeneous Polymerization in Supercritical Carbon Dioxide
TL;DR: In this article, the presence of two reaction loci is not the result of the thermodynamic partitioning between two phases, but rather a kinetic effect, which occurs because part of the radicals generated in the continuous phase, which are driven by thermodynamic equilibrium to diffuse to the dispersed phase, are actually terminated in the former before they can reach the latter.

Solid alkaline fuel cell comprising ion exchange membrane
TL;DR: In this paper, a solid alkaline fuel cell comprising anion exchange membranes which comprise diamines or polyamines coupled to a support polymer via a sulfonamide linkage is presented.
Journal ArticleDOI
Copolymerization of vinylidene difluoride with hexafluoropropene in supercritical carbon dioxide
TL;DR: In this article, the first stages of the reaction were monitored by turbidity measurements and the time/conversion curve was followed gravimetrically to measure the initial rates of polymerization, and obtained copolymers possessed bimodal molecular weight distributions, their average comonomer composition was well described by the Lewis-Mayo equation with the copolymerization parameters rVDF = 4.8 and rHFP = 0.

TL;DR: In this article, a host material comprising a compound having two carbazole moieties which is suitable for blue-emitting OLEDs was presented. But, it has been found that when appropriate substituents are present in the carbazoles structure, the solubility of the compounds can be improved without any adverse effect on the OLED performance.

N-Phenyl carbazole-based host material for light-emitting diodes
TL;DR: In this article, a host material comprising a compound having a carbazole moiety which is suitable for blue-emitting OLEDs was proposed. But the use of the host materials and to an organic light emitting device comprising the host material was not discussed.
