Thermoplastic composite parts in the aerospace industry have recently been increased due to reshaping and reused potentials of thermoplastic materials. The thermoforming process is an effective manufacturing methodology form main benefits are low cost short time. Optimization parameters essential for correct production. In this present study, effects plate geometry connection technique, pre-hea...

Herein, fully hydrocarbon-based ionomer catalyst coated membranes (CCM)s based on sulfo-phenylated polyphenylene biphenyl (sPPB-H + ) are evaluated in a proton exchange membrane water electrolyzer cell at 70 °C. In conjunction with layers incorporating Nafion® D520 ionomer, sPPB-H require lower applied potential than reference NR112 recast of equal thickness, e.g., 1.66 V vs 1.75 1 A cm −2 . In...

Using analytical excited-state gradients, vibrational normal modes have been calculated at the minimum of the electronic excited-state potential energy surfaces for a set of extended conjugated molecules with different coupling between them. Molecular model systems composed of units of polyphenylene ethynylene (PPE), polyphenylenevinylene (PPV), and naphthacene/pentacene (NP) have been consider...
