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 ...
Caracterização de interfaces para aplicações em ultra-alto vácuo através de brasagem dissimilar entre nitreto de boro hexagonal (h-BN), a liga de adição Ag-Cu-Ti e o Mo metálico
(Universidade Federal de São Carlos, 2020-08-14)
This work aimed to evaluate the vacuum brazing of h-BN/Mo systems for fabrication of the BPM (Beam Position Monitor) in synchrotron radiation beam. The h-BN has low surface wettability and is difficult to weld. The materials ...
Development of bio-inspired electromechanical devices based on PBMA-b-(PSS-r-PS) amphiphilic block copolymer
(Universidade Federal de São Carlos, 2024-04-08)
Technological advances in the aerospace, biomedical, and robotics industries stimulate the need for innovative and sustainable devices, such as electromechanical devices (EMDs), which are bio-inspired materials capable of ...
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 ...
Desenvolvimento de sensores colorimétricos baseados em compostos amido/cera de abelha e antocianinas por casting contínuo para embalagens inteligentes

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 ...
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 ...
Design de ligas multicomponentes do sistema Ti-V-Nb-M (M = Cr, Co E Ni) para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2023-05-15)
Body Centered Cubic (BCC) multicomponent alloys have gained attention in the research of materials for H2 storage. These alloys have the potential to optimize H2 storage properties via compositional control. However, the ...
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 ...
Desenvolvimento de concreto geopolimérico leve: viabilidade de aplicação no setor da construção civil
(Universidade Federal de São Carlos, 2023-07-28)
Portland cement is the main component of conventional concrete, considered
the second most consuming material in the world, but its manufacture
accentuates the greenhouse effect. Studies show that the production of ...
