Desenvolvimento de vitrocerâmicos transparentes resistentes ao impacto
(Universidade Federal de São Carlos, 2021-11-11)
Transparent glass-ceramics (GCs) can replace glasses traditionally used as ballistic windows and electronic displays due to their better mechanical properties. This improvement is obtained by the crystallization of phases ...
Computational modeling of rubber multiaxial pressing applied to ceramic materials
(Universidade Federal de São Carlos, 2021-04-07)
Uniaxial and isostatic powder pressing are well known processes. However, disadvantages such as the production of heterogeneous parts or low productivity, respectively, are intrinsic drawbacks. Rubber Multiaxial Pressing ...
Juntas de aço inoxidável super duplex UNS S32760 soldadas por fricção e mistura mecânica (FSW): microestrutura e comportamento de corrosão eletroquímica
(Universidade Federal de São Carlos, 2022-04-29)
In this study, the corrosion resistance of the face and root surface of an AISD UNS S32760 friction stir welded (FSW) joint using optimized parameters was investigated. Microstructural changes were evaluated by MO, SEM and ...
Design, processing, and characterization of high strength precipitation-hardened CrCoNiAlTi high entropy alloys
(Universidade Federal de São Carlos, 2023-03-22)
High Entropy Alloys (HEAs) have been attracting considerable interest in literature. While early studies focused on producing single-phase HEAs, more recent investigations have expanded to multi-phase compositions to take ...
Compósitos de poli(éter imida) com partículas nanoestruturadas de LaNi₅ para armazenamento de hidrogênio
(Universidade Federal de São Carlos, 2023-07-14)
Hydrogen is a promising energy vector for decarbonizing the energy
matrix, but its widespread use requires safe and efficient storage systems. This
study aimed to produce microparticles of polyetherimide with LaNi5 through ...
Injection overmolding of polycarbonate-aluminum alloys hybrid structures
(Universidade Federal de São Carlos, 2023-03-24)
Overlap joints between polycarbonate (PC) and aluminum alloys AA6061 and AlSi10Mg were manufactured by injection overmolding and evaluated regarding the interfacial structure and mechanical performance. The injection ...
Synthesis and characterization of CH3NH3SnI3, Mn doped CH3NH3SnI3 and oxygen-deficient TiO2 as visible-light active semiconductors
(Universidade Federal de São Carlos, 2020-02-14)
CH3NH3SnI3 is an environmentally-friendly (lead-free) perovskite whose synthesis depends on SnI2. Some disadvantages of SnI2 include high cost and tin(IV) contamination. Thus, SnSO4 and C16H30O4Sn are presented as cheaper ...
Desenvolvimento de sensores colorimétricos baseados em compostos amido/cera de abelha e antocianinas por casting contínuo para embalagens inteligentes
(Universidade Federal de São Carlos, 2023-12-19)
Intelligent packaging are systems capable of communicating the conditions of the packed food and different approaches can be used to produce such packaging, for instance, the production of quality indicators based on ...
Monitoramento in/on-line da malaxagem na extrusão: hidrólise e extensão de cadeia do poli(tereftalato de etileno) e fusão do polipropileno
(Universidade Federal de São Carlos, 2020-08-14)
During twin-screw extrusion, understanding and quantifying the behaviour of molten polymers under different conditions is limited by the complex configuration of the equipment. Due to this fact, real-time extrusion monitoring ...
Influência da incorporação de negro de fumo e carbonato de cálcio micro e nanoparticulado nas propriedades reológicas, colorimétricas e mecânicas de filmes de polietileno de baixa densidade
(Universidade Federal de São Carlos, 2021-06-30)
In this work, the influence of incorporation of Carbon Black (CB) and CaCO3, both with different particle sizes, on the rheological, colorimetric and mechanical properties of LDPE films were studied. Three different types ...
