In this work, CO2 adsorption at 273.15 K and N2 77 of mixed matrix membranes has been studied, as a method to directly determine their fractional free volume (FFV). These consist continuous phase copoly(o-hydroxyamide)s (HPA) or copoly(o-hydroxyamide-amide)s (PAA) relatively highly porous polymer network filler (PPN1). Both the pure copolymers (MMMs) have analyzed before after thermal rearrangement (TR) process. The results allowed characterizing pore size distribution studied in 3–15 Å...
The lithium ion is an important type of electrolyte that has technological applications in the manufacture cells; therefore, a better understanding nature its solutions desirable. When associated to radical anion biphenyl organic solvent, it forms conducting comparable strong electrolytes such as perchlorate. We have studied solution dimethoxyethane using DFT calculations. these ionic described terms dynamic equilibrium between different types associations, composition which depends on...
A novel approach for the introduction of alkenyl functionalization in polymers.
Spontaneous disproportionation of lithium biphenyl radical anion into a dianion plus neutral biphenyl, according to 2LiBiph ⇄ Li<sub>2</sub>Biph + Biph, has been evidenced experimentally by UV-vis spectroscopy and backed up theoretically using TDDFT methods.
We report an organic photocatalytic system, namely 3,3′,5,5′-tetra-<i>tert</i>-butyl-4,4′-diphenoquinone (DPQ) and air, capable of coupling efficiently with the photocyclization stilbenes to afford phenacenes. The potential this new mild process is shown synthesis [5]- [7]phenacene, two semiconductors recently implemented into electronic devices, high yields remarkable purity.
The relationships between gas permeability and free volume fraction, intersegmental distance, glass transition temperature, are investigated. They analyzed for He, CO2, O2, CH4, N2 gases five similar polyimides with a wide range of permeabilities, from very low to extremely high ones. It has been established here that there is an exponential relationship the most probable distance as measured by WAXS; in both cases, coefficient depends on kinetic diameter quadratic polynomial preexponential...
