(2023) [Journal article]Four imidazolium-based ionic liquids (IL; 1-butyl-3-methylimidazolium chloride, 1-carboxymethyl3-methylimidazolium chloride, 1,3-dicarboxymethylimidazolium chloride and 1-(2-hydroxyethyl)- 3-methylimidazolium chloride) ... -
Polyamide worm gear : manufacturing and performance
(2012) [Journal article]The focus of this paper is to establish a characterisation method for seven polyamide (PA) grades to determine the major material to manufacture an automotive worm gear. The composite properties were measured according to ... -
Polyester/paper composites : study of manufacturing techniques for product development
(2020) [Journal article]Composite materials using vegetal fibers and industrial waste are being applied in different areas and structures, requiring, more and more, researches that highlight their characteristics. In this context, the study of ... -
Studies on the properties of rice-husk-filled pp composites: effect of maleated PP
(2009) [Journal article]Rice husk is a by-product of rice milling process that usually finds inadequate final disposal (burning, land filling). Thermoplastics composites filled with rice husk flour are materials that offer an alternative for using ... -
Turn on of new electronic paths in Fe-SiO2 granular thin film
(2014) [Journal article]The electrical properties of Fe-SiO2 have been studied in the low-field regime (eDV kBT), varying the injected current and the bias potential. Superparamagnetism and a resistance drop of 4400X (for a voltage variation of ...
