Análise de metabólitos secundários produzidos por fungos endofíticos associados à Cupressus lusitanica
(Universidade Federal de São Carlos, 2009-02-12)
Some phytopatogenic fungi found in Cupressus species produces phytotoxins very aggressive to the host plant. Surprisingly, these toxins are diterpenoids structures, as well as some endogenus metabolites in Cupressus species. ...
Contribuição ao estudo do metabolismo micromolecular de Xylaria sp., um fungo endofítico isolado de Sapindus saponaria
(Universidade Federal de São Carlos, 2006-12-15)
This work reports the study of a surprising plant microorganism relationship, involving the plant Sapindus saponaria, which is rich in antigungal saponins, and an endophyte fungus isolated from the pericarpe of the fruits ...
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 ...
Adição de Michael de α,α-Diciano-Olefinas a Chalconas via organocatálise assimétrica empregando solvente derivado de biomassa
(Universidade Federal de São Carlos, 2018-05-18)
In recent years, organocatalysed reactions have become an important field in asymmetric synthesis. Particularly, Michael addition reactions using various donors and acceptors have been explored to generate substrates that ...
Catalisadores a base de Pt suportados em matrizes mesoporosas de carbono visando a reação de eletrooxidação de glicerol
(Universidade Federal de São Carlos, 2018-08-24)
This work aimed the synthesis, characterization and electrochemical tests of Pt and Pt-Sb nanoparticle catalysts onto mesoporous carbon applied to glycerol electrooxidation reaction. Specifically, the carbon matrixes were ...
Contra eletrodos de sulfetos metálicos aplicados a células solares sensibilizadas por pontos quânticos
(Universidade Federal de São Carlos, 2019-05-22)
The quantum dot-sensitized solar cells (CSSPQ) are considered as third generation solar cell, derived from dye-sensitized solar cells (CSSC). Several works in the literature shown that the optimization of counter electrodes ...
Estudo da influência do glicerol no processo de deposição de ligas Zn-Mn e nos depósitos de Zn-Mn
(Universidade Federal de São Carlos, 2011-02-18)
The influence of glycerol additive on the electrodeposition process of Zn-Mn on Pt substrate from acid baths by means of cyclic voltammetry and the characteristics of the coatings by Scanning Electron Microscopy (SEM), ...
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 ...
Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
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 ...
