During the hydration and hardening process of the conventional concrete, voids between the grains of the aggregate and cementitious matrix are formed. Such voids or pores allow penetration of water and aggressive agents ...

The influence of oxidized multi-walled carbon nanotubes (o-MWCNTs) on the curing kinetics of a novolac resin was studied by means of non-isothermal differential scanning calorimetry. Regarding the kinetics issues, the high ...

Phenol is an expensive and toxic raw material derived from petroleum, for these reasons, it’s necessary to take a look for alternative materials in order to replace it. Lignin represents a good choice, especially in ...

Las excelentes propiedades poliméricas que presentan los compuestos fenólicos del CNSL (Cashew Nut Shell Liquid), lo convierten en una materia prima con gran potencial para la elaboración de resinas denominadas fenólicas, ...

The curing reaction of an epoxy-phenolic resin under different conditions was monitored using rheological measurements. The evolution of viscoelastic properties, such as storage modulus, G′, and loss modulus, G″, was ...

El presente Informe de Ingeniería, trata de brindar conocimientos acerca del Estudio de migración de distintos componentes de materiales plásticos a los alimentos, ya que esta tecnología tiene como principal objetivo ...

La barra estabilizadora es un elemento encargado de reducir el balanceo y por lo tanto garantizar una mejor transmisión de la potencia al suelo por medio de las ruedas, la cual está hecho mayormente de acero. Así mismo, ...

Polymeric sensors with improved resistance to organic solvents were produced via the layer-by-layer thin film deposition followed by chemical cross-linking. According to UV-vis spectroscopy, the mass loss of polyaniline/poly(vinyl ...
