Avaliação da potencialidade do uso de hidrogéis poliméricos na terapeutica de leishmaniose cutânea
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2015-11-10)
Poly(vinyl alcohol) - PVA is a high hydrophilic semicrystalline polymer which has excellent properties such as good chemical resistance and high biodegradability and biocompatibility. Due to its semi-crystalline nature, ...
Preparation of zinc oxide and poly-ethylene oxide composite membranes and their phase relationship
(Universidad Nacional de Colombia Sede Medellín, 2012)
Zinc oxide and organic polymer (poly-ethylene oxide) based nanocomposite membranes were prepared and their phase relationship investigated. The composites were characterized by XRD, Raman scattering, DSC, and impedance ...
Fractographic evaluation of welded joints of PPS/glass fiber thermoplastic composites
(Elsevier B.V., 2019-08-01)
Joints obtained by resistance welding of polyphenylene sulphide (PPS) laminates reinforced with bidirectional glass fiber (GF) fabrics were investigated by fractographic analyses. The welded joints were tested under lap ...
Thermo-sensitive actuator capabilities assessment of a composite material based on a two-way shape memory semicrystalline polymer
(Universidad Nacional de ColombiaMedellín - Arquitectura - Maestría en ConstrucciónEscuela de construcciónFacultad de ArquitecturaMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2018)
Evidence suggests that energy efficiency is one of the most crucial factors to be addressed in XXI century by building industry, and the study of the building envelope, which includes passive systems of dynamic activation ...

(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de MateriaisDepartamento de Engenharia de Materiais, 2022-07-18)
Following the development of new technologies and a consequent over-productivity of consumer goods, the packaging production is constantly increasing. In the food sector, the use of plastic packaging ahead of other types ...
Reactive doping of PAni-CSA and its use in microwave absorbing materials
(Wiley-Blackwell, 2009-01-01)
Conductive coatings have been studied for static dissipation and as microwave absorbing materials. the doping process of polyaniline (PAni), which makes it conductive, is an important stage that determines the coating ...
Accelerated ultraviolet aging of structural and luminescent properties of the ureasil-polyether hybrid materials U-PEO:Eu3+ and U-PPO:Eu3+
(2019-08-26)
In this paper, we evaluate the role played by the polyether type and chain length on the complexation of Eu3+ by the urea group of siloxane-polyether organic-inorganic hybrid materials based on polyethylene oxide (U-PEO, ...
Evaluation of crystallization kinetics of poly (ether-ketone-ketone) and poly (ether-ether-ketone) by DSC
(Departamento de Ciência e Tecnologia Aeroespacial, 2010)
The poly (aryl ether ketones) are used as matrices in advanced composites with high performance due to its high thermal stability, excellent environmental performance and superior mechanical properties. Most of the physical, ...
