To investigate confined crystallization of polymer chains with/without fixed chain ends in nanoscale spaces, a series of blends of poly(vinylcyclohexane)-b-poly(ethylene)-b-poly(vinylcyclohexane) (PVCH-PE-PVCH) and ethylene polymers with different chain lengths, i.e. (i) paraffin (M¯n = 364 g/mol) and (ii) polyethylene (homo-PE, M¯w = 15 000 g/mol), were prepared by spin-coating. The phase morphologies...
Ammonia-oxidizing bacteria (AOB) play an importance role in nitrogen conversion in biological wastewater treatment systems. AOB produce soluble microbial products (SMPs) and nitrous oxides (N 2 O), respectively, as aqueous and gaseous products at a trace level in their metabolism and decay processes. In this work both experimental and modeling approaches were used to explore the formation...
The surface-directed spinodal decomposition (SDSD) of polymer binary mixture with different values of surface potential is numerically simulated in three-dimension (3D) by cell dynamic systems (CDS). Furthermore, the growth laws of the wetting layer are theoretically analyzed by the current equation and the dynamical scaling. The results show that the thickness of the wetting layer increases with...
The characteristic features of the morphology and dynamics of binary mixture for substrate-directed spinodal decomposition (SDSD) in three dimensions have been studied using numerical simulations. The simulation results show that the formation of the wetting layer on the substrate interface follows the power-law growth. It is found that the continuous influence of anisotropic diffusive behavior arose...
