Insect damaged wood as a source of reinforcing filler for thermoplastic composites

open access: yesMaderas: Ciencia y Tecnología, 2017
In this study, wood polymer composites were manufactured using insect damaged Eastern Black Sea Fir (A. Nordmanniana) wood as filler. The effects of wood type (sound vs insect damaged) and presence of coupling agent (0% vs 3%) on the flexural, tensile ...

Phase separation in mixtures of colloids and long ideal polymer coils

open access: yes, 2000
Colloidal suspensions with free polymer coils which are larger than the colloidal particles are considered. The polymer-colloid interaction is modeled by an extension of the Asakura-Oosawa model. Phase separation occurs into dilute and dense fluid phases

Synthetic waterproofing membranes and auxiliary separating layers in the inverted flat roof. Pressure effect on the degradation

open access: yesMateriales de Construccion, 2018
Flat roofs are inverted when the insulation material is placed over the waterproofing membrane. This widely-used constructive system sets materials which may interact easily with each other causing their deterioration.
