Parametrização de ligantes em reações catalisadas por metais de transição
(Universidade Federal de São Carlos, 2023-04-24)
The approach of statistical methods capable of accurately predicting the
relationship between catalyst structure and reactivity represents a major impact on reaction
development, since both reactivity and selectivity of ...
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 vidro metálico de elevada resistência à corrosão e ao desgaste utilizando ferro-gusa como precursor
(Universidade Federal de São Carlos, 2023-08-01)
Metallic glasses exhibit exceptional properties such as high mechanical strength, thermal stability, and excellent magnetic properties. In this study, our aim was to develop a high corrosion and wear-resistant metallic ...
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 ...
Emprego de agente complexante e irradiações por feixe de elétrons e laser femtosegundos como estratégias para alterações da propriedade fotoluminescente do α-Ag2WO4
(Universidade Federal de São Carlos, 2023-06-22)
The discovery of room temperature photoluminescence has driven the development of various optical-electronic devices, motivated the search for new photoluminescent materials, and stimulated the modeling of this property ...
Desenvolvimento de método de análise direta de folhas de soja e milho empregando a Laser-Induced Breakdown Spectroscopy (LIBS)
(Universidade Federal de São Carlos, 2023-06-22)
This academic master's dissertation was devoted to the development of analytical methods for the
determination of macronutrients (P, K, Ca, Mg) and micronutrients (B, Cu, Fe, Mn, S and Zn) in corn, soy (wihout and with ...
Caracterização microestrutural, eletroquímica e tribológica de revestimentos HVAF Fe₆₈Cr₈Mo₄Nb₄B₁₆
(Universidade Federal de São Carlos, 2023-02-28)
High corrosion and wear resistance are basic requirements for materials that operate in aggressive environments such as those found in the petrochemical, mining and agro-industry industries. Fe-Cr-B-based vitreous/nanocrystalline ...
Campos de Yang-Mills fracamente estáveis na esfera de dimensão quatro
(Universidade Federal de São Carlos, 2023-05-03)
In this work we made a quick study on some basic results related to Groups and Lie Algebras,
action of Groups and Fiber Bundles with the objective of defining connections in Principal Bundles
and, later, in Associated ...
