Acilação e alquilação fotoquímica de heteroarenos utilizando diacetil
(Universidade Federal de São Carlos, 2018-11-01)
N-heterocycles are important building blocks in the synthesis of bioactive compounds, besides that many of them are present in natural products. Most of the methodologies for heteroarene functionalization requires several ...
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 ...
Degradação eletroquímica e fotoquímica em série do herbicida picloram utilizando um anodo dimensionalmente estável e luz UV
(Universidade Federal de São Carlos, 2016-10-21)
A coupled electrochemical-photochemical system (EQ-FQ) using a dimensionally stable anode (ADE) and UV light was used for the oxidation and mineralization of picloram (PCL) herbicide, which is a potential contaminant of ...
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, ...
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 ...
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 ...
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 ...
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 ...
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 ...
Estudo In vitro de nanocompósitos para a liberação lenta de nitrogênio sobre a alimentação animal
(Universidade Federal de São Carlos, 2016-03-29)
Supplementation with nonprotein
nitrogen (NPN) has been widely used in ruminant feeding in diets of low
quality forages. This is because these animals have a number of microorganisms
in the rumen able to use ammonia for ...
