High-performance binary blends between poly(ether imide) (PEI) and flame-retardant poly(butylene terephthalate) (PBT) are modified with 5, 10, and 15 wt% of poly(tetrafluoroethylene) (PTFE) using a two-step melt-processing ...

As gasification reactivity of carbonaceous solid material chars is known to be strongly dependent on their formation conditions, a comprehensive study was carried out on the effects of pyrolysis conditions on structure of ...

En el siguiente artículo proponemos abordar de manera crítica algunas de las expresiones literarias que se dan al calor de las nuevas tecnologías. A partir de un corpus ecléctico (de Charly Gradin, Juan José Mendoza y ...

Pulverized coal combustion is determined by char chemical reactivity, which depends of its morphology developed during the devolatilization process. In this work, some empirical relationships were obtained, in order to ...

In-depth understanding of the thermal stability of polymer-clay nanocomposites requires the use of advanced time-resolved techniques combined with multivariate data analysis, as well as the preparation of layered nanofillers ...

The aim of this study was to determine the Arrhenius parameters and degradation mechanism for each component of biomass, including extractives, water, hemicellulose, cellulose and lignin. A statistical tool (F-test) was ...

Similar to letting yourself be guided by sound in a dance, this master's research was conducted by echoing a question: What can dance in a curriculum that opens up to experimentation, so that body and thought move and ...

There is an increasing concern about the formation of halogenated compounds when sodium hypochlorite (SH) is used as food sanitizer. This research evaluated the quality of watercress harvested in two seasons treated with ...
