Estudos da expressão e da função do gene sintase de quitina em Atta sexdens
(Universidade Federal de São Carlos, 2018-04-06)
In Brazil, leaf-cutting ants belonging to the genus Atta and Acromyrmex and are considered as pests in agricultural and forestry regions that can lead to great economic losses. The aim of this work was to identify the ...
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 ...
Heterostructure formation of BiVO4 with different Bi compounds : role of the heterojunction on photocatalytic properties
(Universidade Federal de São Carlos, 2016-08-29)
Semiconductors employed as photocatalysts that can be activated by
visible irradiation have attracted intense scientific interest due to their applications in
heterogeneous photocatalysis. BiVO4 is a semiconductor with ...
Produção e caracterização de mantas de nanofibras poliméricas eletrofiadas contendo proantocianidinas e sua potencial aplicação no tratamento de lesões cutâneas
(Universidade Federal de São Carlos, 2018-11-23)
The development of novel biodegradable and biocompatible nanofibrous membranes are highly desirable for biomedical applications, including drug delivery and wound dressing. Thus, the present thesis focused on the development ...
Avaliação de novas arquiteturas de carbono para o desenvolvimento de sensores eletroquímicos para a determinação de espécies de interesse em diferentes matrizes de amostras
(Universidade Federal de São Carlos, 2019-03-01)
In this doctorate work the efforts were expended in the electrochemical study and electroanalytical application of electrochemical sensors based on two carbonaceous structures: diamond-like carbon (DLC) and carbon black ...
Desenvolvimento de procedimentos para a síntese e caracterização de catalisadores e de biodiesel
(Universidade Federal de São Carlos, 2017-06-08)
ABO3 basic catalysts were synthesized by the nitrate-b-alanine solution combustion method. The catalysts powders were produced by self-combustion in times up to 5 min, presenting high crystallinity and single-phase, without ...
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 ...
Avaliação do uso de múltiplas linhas para a determinação de metais por espectrometria de emissão óptica com plasma acoplado indutivamente
(Universidade Federal de São Carlos, 2010-06-11)
The aim of this thesis was the evaluation of the use of multiple lines for determination of metals by inductively coupled plasma optical emission spectrometry (ICP OES) with Littrow optical system, Echelle polychromator ...
