Stereocomplex crystallization in cyclic polymer blends studied using dynamic Monte Carlo simulations

Abstract

Due to the absence of chain ends, cyclic polymers exhibit different crystallization behaviours from linear polymers. In the current work, dynamic Monte Carlo simulation method was used to explore stereocomplex...

Local segmental miscibility dominating stereocomplex crystallization in polymer blends

“…35 The final SC contents of those systems at different crystallization temperatures were further counted. Based on the crystal structure of SCs revealed by Tsuji et al 36 and our previous calculation methods, 14,22,25,26,37 one SC bond and one HC bond were defined as follows: if the ratio of the number of crystalline bonds belonging to A chains in the neighboring area of one crystalline bond to that of the crystalline bonds belonging to B chains in the same neighboring area falls between 0.5 and 2, the bond will be classified as a SC bond. However, if the ratio is outside this range, the bond will be classified as a HC bond.…”

Fabrication of BiVO4 submicron rods photoanodes through phase transition assisted by Mo doping

“…However, most of these reported 1D nanostructures are wide bandgap semiconductors like TiO 2 or ZnO, which can harvest only ultraviolet light. [16][17][18] Monoclinic scheelite bismuth vanadate (BiVO 4 ), which has an ideal bandgap of 2.4 eV and a relatively high theoretical photocurrent density (7.5 mA cm −2 ) and STH conversion efficiency (9.2%), has been regarded as a more promising photoanode material for PEC water splitting than TiO 2 and ZnO. [19][20][21] Many pioneering crystallographic/morphological studies were used to try to improve the PEC performance of BiVO 4 .…”
