Evaluation of the combustion characteristics of railroad waste using a cone calorimeter
For this study, we categorized waste from railroad operation into seven types; i.e., wood, vinyl, fiber, Styrofoam, food, paper and plastic. We then performed a combustion test using a cone calorimeter that is used widely for evaluating the combustion properties of combustible materials, to evaluate the heat release rate, smoke production rate, carbon monoxide production, carbon dioxide product...
متن کاملPhotophysics of a poly„phenylenevinylene... with alternating meta-phenylene and para-phenylene rings
We have investigated the photophysics of the luminescent polymer poly~1,3-phenylenevinylene-alt-2,5dioctyloxy-1,4-phenylenevinylene! by a variety of optical spectroscopies. The incorporation of alternating meta-phenylene and para-phenylene rings restricts conjugation with respect to poly~para-phenylenevinylene! derivatives. As a consequence, excited states are blueshifted and the nonlinear susc...
متن کاملTheoretical studies of poly(para-phenylene vinylene) (PPV) and poly(para-phenylene) (PPP)
The electroluminescence from PPV and the blue light emission from PPP constitute exciting subjects of study. The band gap of these semiconducting polymers can be engineered in a wide range from red to ultraviolet by structural changes made on them. In the present work, we present a theoretical approach based on semiempirical and ab initio total energy and force calculations of PPV and PPP. We p...
متن کاملPhotophysics of Poly(p-Phenylene Vinylene) Films
We report on time resolved photoluminescence (PLRT) measurements in poly(p-phenylene vinylene) (PPV) films irradiated by laser in the presence of air. We observe a PL intensity enhancement and a biexponential decay dynamics of PL signal for all irradiated films. These results can be understood in terms of a chain shortening process due to carbonyl incorporation and formation of an energy profil...
متن کاملCyclodextrin-grafted poly(phenylene ethynylene) with chemically-responsive properties.
Water-soluble poly(phenylene ethynylene) carrying beta-cyclodextrin was prepared; the polymer exhibited a fluorescence color change or quenching, depending on the kind of guest.
