Influência dos defeitos nas funcionalidades elétricas de ZnO, AgO e polianilina
(Universidade Federal de São Carlos, 2023-03-03)
The optical and electrical properties in a semiconductor can be modeled by structural defects. In this thesis, we study the influence of defects on the optical and electronic properties of organic and inorganic semiconductors ...
Desenvolvimento de eletrocatalisadores de sulfeto de molibdênio para produção de hidrogênio via eletrólise da água
(Universidade Federal de São Carlos, 2023-03-31)
The amorphous molybdenum sulfide, MoSx, has shown to be an excellent electrocatalyst for the hydrogen evolution reaction (HER) and can be synthesized by electrodeposition. In this study, the electrodeposition of MoSx on ...
Desenvolvimento do aplicativo "O Número Secreto" e uma experiência de aplicação para alunos do ensino fundamental
(Universidade Federal de São Carlos, 2023-05-03)
The present work has, as its objective, the development of an application of the game “The Secret Number”, available on the OBMEP´s website, and its proposed use in the classroom. Currently, Math teachers face enormous ...
Effect of measurement errors on double sampling S² control chart
(Universidade Federal de São Carlos, 2023-06-02)
Product quality can be understood as inversely proportional to the variability in its production process. The control chart is a well-established statistical tool for quantifying and analyzing this process' variability ...
Inferência em redes aleatórias com pesos discretos
(Universidade Federal de São Carlos, 2023-04-04)
Random networks have been widely used to describe interactions between objects, including interpersonal relationships between individuals. One of the most important features of networks is the presence of communities, which ...
Espectroscopia eletrônica de moléculas halogenadas
(Universidade Federal de São Carlos, 2022-09-29)
We present a theoretical-experimental investigation of the valence state excitation of dichloromethane (CH2Cl2) and trichloromethane (CHCl3) molecules in the gas phase. The CH2Cl2 molecule was investigated using electron ...
Hidrogenação de CO2 sobre catalisadores à base de elementos não-nobres: a influência da composição química do catalisador e de condições reacionais na produção de álcoois
(Universidade Federal de São Carlos, 2022-11-30)
Strategies to reduce CO2 emissions and control the increase in atmospheric levels of this gas are urgent. A promising approach to help minimize the accumulation of CO2 in the atmosphere and the corresponding negative ...
Propagação de rumor em uma população cética em N
(Universidade Federal de São Carlos, 2023-03-30)
We consider two models for information propagation in N. In both models, the individuals (one per site of N) have random, independent, and equally distributed radius. At the beginning only the individual at 0 has the ...
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 ...
Correlação estrutura x propriedades de transporte de CO2 em membranas de poli(éterimida)/líquido iônico
(Universidade Federal de São Carlos, 2017-09-28)
The increase in the emission of carbon dioxide (CO2) from the burning of fossil fuels contributes directly to changes in the environment. For post-combustion CO2 capture, the use of polymer membranes has gained prominence ...
