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 ...
A vida urbana transformada a partir da valoração da caminhabilidade. Explorações Urbanas em Zaragoza (ES)
(Universidade Federal de São Carlos, 2020-10-30)
Urban walkability, an insurgent topic in contemporaneity, brings us new perspectives for the qualitative improvement of the urban environment in relation to the human scale. Since the exacerbated growth of cities in the ...
Obtenção de sachês biodegradáveis de amido reforçados com nanopartículas de CuO para liberação de nutrientes minerais
(Universidade Federal de São Carlos, 2020-12-18)
Fertilizers have been used as agricultural inputs to allow maximum yield during the growth of crops. One of the significant challenges is the efficiency of the plant's nutritional process. It is necessary to use excessive ...
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 ...
Análise experimental da eficácia de um método de inspeção da interface de usuário para predição da resposta emocional
(Universidade Federal de São Carlos, 2020-12-18)
In the area of Human-Computer Interaction (IHC), evaluations help to know the desires and problems that people face when interacting with user interfaces (UI). Evaluations can be carried out in order to investigate aspects ...
Materiais para aplicações eletroquímicas: otimização da síntese de grafeno/TiO2-RuO2 e estudo da retificação de corrente iônica em nanoporos
(Universidade Federal de São Carlos, 2020-05-19)
The current energy outlook points to the need to implement methodologies that value the reduction of energy consumption, as well as the use of cleaner and more sustainable processes of production, conversion, and storage ...
Estudo teórico de nano sistemas de azulenos: azulfenos, ANTs, poliazulenos e polinaftalenos
(Universidade Federal de São Carlos, 2020-08-03)
Azulene-based nanographene-like materials are predicted and studied to reveal the molecular properties of these new materials. C48H18/(G-48), C68H22/(G-68), and C88H26/(G-88) nanographenes and their isomers based on azulene ...
Polipropileno reciclado para contato com alimento: etching e deposição de filmes de carbono amorfo hidrogenado por plasma
(Universidade Federal de São Carlos, 2020-09-30)
The increasing applications of polymers make this material one of the most consumed in the world market. Accompanying this scenario is the generation of waste, and although plastic has gradually conquered its space as a ...
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 ...
Estudo de Ligas Fe-Nb-B Nanocristalinas Eutéticas Ultrafinas e Laser Cladding de Pós Atomizados
(Universidade Federal de São Carlos, 2020-05-20)
Fe-Nb-B alloys have gained much attention in recent years because of the possibility to obtain different constituents in nanostructured composites, amorphous and ultrafine eutectics (scale of 100 nm to 1 μm) alloys depending ...
