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 ...
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, ...
Desenvolvimento de um imunossensor descartável acoplado a um sistema microfluídico para determinação de um biomarcador tumoral
(Universidade Federal de São Carlos, 2016-02-19)
Breast cancer is the most common type of cancer among women and results in 70% of cases of estrogen receptor alpha (ERα)
overexpression, a tumor biomarker. In the present study we developed a
sensitive and low cost ...
Compostos carbonílicos heterobimetálicos de Ru(II)/Fe(II) : propriedades citotóxicas e estudo da interação com BSA e DNA
(Universidade Federal de São Carlos, 2016-03-30)
Ruthenium and iron-based drugs are an option for the development of improved chemotherapeutic agents for cancer treatment with lower toxicity. Thereby, this work present the in vitro cytotoxic activity and in vitro interaction ...
Abordagens sintéticas para a funcionalização de novas porfirinas
(Universidade Federal de São Carlos, 2016-09-30)
Herein, we optimized some conditions in the synthesis of a β-octasubstitued porphyrin with electron withdrawing groups (1). This system was used to study the bromination of the meso position aiming at subsequent ...
Determinação de metais por técnicas espectroanalíticas em amostras de carne e sangue de bovinos submetidos à dieta com adição de erva-mate (Ilex paraguariensis, St. Hilaire)
(Universidade Federal de São Carlos, 2016-05-23)
Given the importance of quality in the bovine meat and its relationship with the diet submitted to animals, this master dissertation has the proposition to evaluate the Ca, Cu, Fe, K, Mg, and Zn concentrations changes in ...
Determinação de arsênio total e inorgânico em sucos de frutas e arroz por ICP-MS
(Universidade Federal de São Carlos, 2016-07-07)
Analytical procedures using inductively coupled plasma mass spectrometry (ICP-MS) for the determination of total As in rice samples and fruit juices and inorganic As in rice samples were developed. A microwave-assisted ...
Efeito da inserção de nanopartículas sintéticas preparadas por rota coloidal em matriz acrílica comercial de uso odontológico
(Universidade Federal de São Carlos, 2016-03-11)
Acrylic resins are very used in dentistry to dental restorations and manufacture of
prostheses. New compositions of acrylic resin have been developed through the
incorporation of silver nanoparticles due to the antimicrobial ...
