Estudo químico dos fungos Stachybotrys levispora e Curvularia inaequalis: uso da rede molecular para a identificação de novos metabólitos
(Universidade Federal de São Carlos, 2019-05-03)
Saprobic fungus are being used as an alternative strategy to reduce the use of pesticides harmful to the environment. These microorganisms produce substances capable of inhibiting pathogens that affect agriculture. The ...
Síntese e caracterização de complexos de Cu(II), Ag(I) E Zn(II) com tripeptídeos: avaliação de atividade com xanthomonas citri subsp. citri
(Universidade Federal de São Carlos, 2019-09-06)
SYNTHESIS AND CHARACTERIZATION OF Cu (II), Ag (I) AND Zn (II) COMPLEXES WITH TRIPEPTIDE LIGANDS: ACTIVITY EVALUATION IN XANTHOMONAS CITRI SUBSP. CITRI. In the search for new active substances against phytopathogens, were ...
Estudo da comunidade bacteriana associada a Podocarpus macrophyllus: interações na microbiota, compostos fixos e voláteis, e do potencial de aplicação na biotecnologia
(Universidade Federal de São Carlos, 2019-06-05)
The diversity of the bacterial community associated with the Podocarpus Macrophyllus plant has been systematically studied in order to determine the genera of bacteria that are commonly associated with this plant, as well ...
Synthesis and characterization of micro-and mesoporous materials for catalytic biomass upgrading
(Universidade Federal de São Carlos, 2019-05-16)
In the last years, biomass, especially lignocellulosic, has emerged as an alternative source of carbon. From the fractionation of lignocellulosic biomass, a series of chemical compounds or platforms can be obtained, having ...
Desenvolvimento de procedimentos de preparo de amostras de difícil mineralização para análise direta por laser-induced breakdown spectroscopy (LIBS)
(Universidade Federal de São Carlos, 2019-08-27)
This doctoral thesis proposes sample preparation combined with the use of laser-induced breakdown spectroscopy (LIBS) for analysis of difficult-to-mineralize samples focusing on the analytical development of LIBS as well ...
Estudo da corrosão atmosférica do aço AISI 1020 usando a técnica de ruído eletroquímico e microscopia óptica
(Universidade Federal de São Carlos, 2019-12-13)
The objective of this work was to study the corrosion of AISI 1020 exposed in an atmosphere containing acetic acid (HAc) vapor. Electrochemical noise (RE) oscillations and surface micrographs of the samples were obtained ...
Efeitos térmicos durante a foto-eletro-oxidação de glicerol catalisada por CdS
(Universidade Federal de São Carlos, 2019-10-25)
Cadmium sulfide (CdS) is one of the most important chalcogenides applied to water splitting, which has a band gap of 2.4 eV that suits very well with the solar spectrum. Moreover, CdS possesses a strong reduction activity ...
Síntese de acil fosfodiésteres por mecanoquímica: uma metodologia de química verde
(Universidade Federal de São Carlos, 2019-08-22)
Green chemistry is very concerned with the sustainability of chemical reactions, where one of the objectives, which in the formulation/remodeling of synthetic routes can replace toxic solvents with solvents of lower toxicity, ...
Preparação de eletrodos com novos materiais à base de carbono para aplicação em eletroanalítica
(Universidade Federal de São Carlos, 2019-06-28)
In this work, electrochemical sensors were developed using two different types of carbon material: carbon black (CB) and reticulated vitreous carbon (3D-RVC) for electrochemical studies and analytical applications. First, ...
Fosfoenolpiruvato carboxiquinase imobilizada: novos modelos de triagem de ligantes
(Universidade Federal de São Carlos, 2019-08-30)
Phosphoenolpyruvate carboxykinase (PEPCK) is a ubiquitous enzyme found in all known groups of organisms, acting in the reversible conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) and CO2, in the presence of ...
