Síntese e estudo das propriedades fotoluminescentes dos pós de CaTiO3 decorados com α-Ag2WO4
(Universidade Federal de São Carlos, 2016-02-24)
The CaTiO3 (CT) and α-
Ag2WO4 (AW) are known to have photoluminescent properties, which is favored by
the existence of a structural disorder. The combination of these two materials was
observed through decoration of ...
Nanomateriais semicondutores aplicados na fabricação de dispositivos eletroquímicos
(Universidade Federal de São Carlos, 2019-03-22)
This dissertation was subdivided into 3 different studies. In the first study, it was proposed the development of a photo-electrochemical system for the removal of caffeine in natural water samples. Photo-anodes made with ...
Influência do empacotamento cristalino nas conformações de N,N -bis(piridina-n-ilmetil) etanodiamidas e tioamidas análogas (n= 2, 3, 4)
(Universidade Federal de São Carlos, 2010-07-30)
The rational development of crystal structures requires consistent and directional formation of its synthons to control the supramolecular arrangement. Hydrogen bonds between atoms with high electronegativity (OH O and ...
Nanocristais de TiO2 : relação entre parâmetros morfológicos, estruturais e fotocatálise
(Universidade Federal de São Carlos, 2010-02-26)
In this work, morphologically different TiO2 nanocrystals were synthesized through the OPM method with the objective of performing a comparative study related to photoactivity. Morphological characterization was performed ...
Síntese assistida por microondas de LiMn2O4, caracterização e testes como catodo para dispositivos de armazenamento de energia
(Universidade Federal de São Carlos, 2011-03-02)
Lithium manganese oxide - LiMn2O4 - was produced by a microwaveassited solid state reaction. Solid mixtures containing LiOH.H2O and -MnO2 (synthesized electrolytically) underwent microwave irradiation for 3, 4 and ...
Ligação covalente coordenada boro-nitrogênio : um estudo comparativo entre moléculas derivadas do etano, eteno e etino orgânicos e inorgânicos
(Universidade Federal de São Carlos, 2016-12-06)
This work consists in the theoretical analysis and comparison of some
organic compounds and its similar inorganics, through the change of the BN pair,
and, in some cases, the BP pair, in the place of CC pair. First, ...
Complexo luminescente de Ru(II)-Perileno: avaliação da citotoxicidade e da fotocitotoxicidade em células de melanoma murino B16F10 in vitro e in vivo
(Universidade Federal de São Carlos, 2017-08-17)
Cutaneous melanoma is one of the most feared cancers worldwide due to resistance to treatments and the high capacity to develop metastases. Photodynamic therapy (PDT), a minimally invasive therapeutic modality, is a promising ...
Instabilidades em eletrocatálise: cinética complexa catalisada por superfícies modelo
(Universidade Federal de São Carlos, 2018-02-28)
The electro-oxidation of small molecules is an area of great interest due to its application in energy converting systems, such as fuel cells. The reactions present in these systems involve several reaction pathways - which ...
Estudo de alterações metabólicas nos fungos endofíticos Penicillium brasilianum e Penicillium griseoroseum
(Universidade Federal de São Carlos, 2011-08-26)
Microorganisms, known as being relatively simple, have shown a great adaptation power to different nutritional situations by changing their metabolism with lack or supply of nutrients in the culture medium. This feature ...
Uso de imagens digitais e ferramentas quimiométricas para identificação e determinação de Cr (VI) em solos contaminados
(Universidade Federal de São Carlos, 2012-03-23)
The determination of toxic metals in soils is an important factor to access their quality or identify possible contamination. The element Cr has double feature: Cr (III) is essential for human beings and Cr (VI) is toxic. ...
