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 ...
Desenvolvimento de procedimentos para análise inorgânica de biodiesel usando técnicas espectroanalíticas
(Universidade Federal de São Carlos, 2010-08-25)
In this work, analytical procedures are proposed for the determination of major and trace elements in biodiesel samples employing flame atomic absorption spectrometry (F AAS), inductively coupled plasma optical emission ...
Ligação entre as propriedades estruturais, ópticas, eletrônicas e atividade fotocatalítica de Ag3PO4:Mo
(Universidade Federal de São Carlos, 2018-09-25)
Silver phosphate (Ag3PO4) has received considerable attention from the scientific community due to photocatalytic and photoluminescent properties. However, some alternatives were sought to improve the performance of these ...
Síntese assimétrica dos componentes do feromônio sexual da lagarta-parda, Thyrinteina arnobia (Lepidoptera: Geometridae)
(Universidade Federal de São Carlos, 2013-01-31)
The pheromones play an important role in chemical communication between alive organisms. They can be used in agriculture to pest control. The brown-caterpillar, Thyrinteina arnobia, is considered in Brazil a major pest of ...
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 ...
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 ...
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 ...
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 ...
Avaliação por RMN de alta resolução da presença de cereais não maltados na produção de cervejas
(Universidade Federal de São Carlos, 2020-07-16)
Statistics show that beer is the most widely consumed alcoholic beverage in the world and it is made up of water, barley malt, hops and yeast as main ingredients. The use of non-malted cereals in beer production is common ...
