Photodegradation resistance and flammability of bio-based wood-nanoclay-polyurethane foam nanocomposites
(2024) [Artículo de periódico]Rigid polyurethane foams (RPUF) filled with lignocellulosic fillers have gained considerable interest due to their mechanical performance and eco-friendly characteristics. However, their flammability and photodegradation ... -
Hydrophobic polyurethane foams reinforced with microcrystalline cellulose for oil spill clean up
(2023) [Artículo de periódico]Oil spills into water have been an environmental concern since the beginning of large-scale oil extraction. In this study, flexible open-cell polyurethane (PU) foams with added microcrystalline cellulose (MCC) were formulated ... -
Spectroscopic insights into the role of CO2 on the nature of Cr species in a CrOX/Al2O3 catalysts during ethane dehydrogenation with CO2
(2023) [Artículo de periódico]The dehydrogenation of ethane with CO2 was studied on CrOx/Al2O3 catalysts (8 wt% of CrOx) in the 600–675 °C temperature range. The role of CO2 was determined by comparison with catalytic and spectroscopic data of ethane ... -
Selection of automotive brake friction composites reinforced by agro-waste and natural fiber : an integrated multi-criteria decision-making approach
(2024) [Artículo de periódico]The aim of this study is to develop a method for selecting and ranking automotive brake friction composite materials made from agro-waste and natural fibers. This is achieved by using an integrated multi-criteria decision-making ... -
Avaliação preliminar da influência do cobre oriundo de sucata reprocessada na microestrutura, dureza e resistência à compressão do zamac 5
(2023) [Artículo de periódico]Zamac é uma liga metálica composta de zinco, alumínio, magnésio e cobre. Suas propriedades de processamento, como baixo ponto de fusão e alta fluidez a quente faz com que a indústria reprocesse o refugo da produção de zamac ... -
Influence of chemical nature of citric and tartaric acids on reaction time of the crosslinking of polyvinyl alcohol hydrogels
(2024) [Artículo de periódico]Poly(vinyl alcohol) (PVOH) is a water-soluble polymer having a hydroxyl group as a functional group contributing to excellent membrane-forming and mechanical performance. PVOH is obtained by the hydrolysis of polyvinyl ... -
Quantifying power system frequency quality and extracting typical patterns within short time scales below one hour
(2024) [Artículo de periódico]This paper addresses the lack of consideration of short time scales, below one hour, such as sub-15-min and sub-1-hr, in grid codes for frequency quality analysis. These time scales are becoming increasingly important due ...
