Metodologia para a determinação das propriedades mecânicas de compósitos de poliamida 6.6 reforçados por fibras de vidro longas através da simulação de injeção
(2017-12-20)
The use of long glass fiber-reinforced thermoplastic composites has increased considerably in the last years. However, the mechanical properties of these materials are strongly dependent on their microstructure (orientation ...
Blendas a base de biopolímeros para liberação controlada de agroquímicos
(2014-05-29)
The incorporation and encapsulation of fertilizers in polymers blends are methods that can be used to reduce losses and to minimize environmental pollution. In this work, blends of Soy Protein Isolate (SPI) and Polylactide ...
Propriedades fisico-químicas, mecânicas e tribológicas de filmes finos de Si3N4 contendo MoS2
(2014-06-24)
One of the purposes of surface engineering is to combine physical-chemical,
tribological and mechanical properties of materials aiming high hardness, low friction
coefficient and high wear resistance, associated with ...
Propriedades físicas de sedas de lepidópteros neotropicais
(2022-05-21)
Silk fibers produced by non-domesticated moths have distinct properties from the widely cultivated Bombyx mori silk and show promising applications in several areas. However, few Lepidoptera species have their silk adequately ...
Entendimento químico da adesão de filmes de carbono amorfo em ligas ferrosas por meio de intercamadas contendo silício
(2021-07-29)
Diamond-like Carbon films (DLC) films, despite research being developed over four decades, have restricted industrial use and prevent massive application in recent years due to the low adhesion of this material to ferrous ...
Poliuretanos fotoativos como estratégia de prevenção à resistência bacteriana
(2022-08-11)
Quantum carbon dots (CQDs) are amorphous carbon nanoparticles that have specific functionalities, among them, the fluorescence emission at particular wavelengths and the production of singlet oxygen (1O2). However, due to ...
Estudo da influência de resinas de tack em formulações elastoméricas e metodologias de avaliação aplicadas
(2022-09-20)
The present work aimed to evaluate the influence of different types of tack resins in elastomeric formulations, as well as to develop a simple, robust and reproducible test methodology to evaluate the tack of these elastomeric ...
Síntese e caracterização de redes metalorgânicas e a busca pela atividade biomimética tipo peroxidase
(2022-03-08)
Metal-organic frameworks (MOF) are porous materials made up of metallic ions coordinated with organic ligands, forming two-dimensional and three-dimensional structures. Since their appearance, these structures have attracted ...
Influência da radiação no comportamento de atrito de filmes finos de dióxido de titânio: fototribologia
(2022-08-17)
In dry sliding of two surfaces, the friction force depends on the pair of materials and the contact conditions. If the material and operating conditions remain unchanged, the friction force is constant. Techniques for ...
