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 ...
Nanomateriais semicondutores aplicados na fabricação de dispositivos eletroquímicos
(Universidade Federal de São Carlos, 2019-03-22)
This dissertation was subdivided into 3 different studies. In the first study, it was proposed the development of a photo-electrochemical system for the removal of caffeine in natural water samples. Photo-anodes made with ...
Caracterização dos processos eletroquímicos em filmes automontados de poli(o-metoxianilina) e poli(ácido-3-tiofeno acético).
(Universidade Federal de São Carlos, 2003-05-19)
In this work, the electrochemical characterization of a self-assembled
film containing two conductive polymers, poly(o-methoxyanilina)(POMA) and poly(3-
thiophene acetic acid)(PTAA), is presented. The technique that allows ...
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 ...
Estudo e desenvolvimento de banhos contendo benzotriazol para eletrodeposição de níquel e caracterização química, física e morfologica dos filmes
(Universidade Federal de São Carlos, 2008-03-07)
In this work, nickel electrodeposition has been studied in the presence of the additives BTAH and/or EDTA onto platinum substrate from Watts plating bath, at different pH. The deposition and dissolution processes with or ...
Complexos de Cromo(III)-salen como catalisadores em reações de oxidação de sulfetos
(Universidade Federal de São Carlos, 2009-02-06)
Transition metal complexes participate in many chemical processes. The study of these complexes is very interesting because of the diversified chemistry and great utility. Transition metal complexes act as catalysts in ...
Nanocristais de TiO2 : relação entre parâmetros morfológicos, estruturais e fotocatálise
(Universidade Federal de São Carlos, 2010-02-26)
In this work, morphologically different TiO2 nanocrystals were synthesized through the OPM method with the objective of performing a comparative study related to photoactivity. Morphological characterization was performed ...
