1. Filmes de diamante nano/ultrananocristalinos dopados com boro: propriedades morfológicas, estruturais e eletroquímicas / Boron doped nano/ultrananocrystalline diamond films: morphological, structural and electrochemical properties
É apresentado um estudo sistemático do processo de obtenção e caracterização de filmes de diamante nanocristalino dopados com boro. Os filmes foram obtidos pela técnica HFCVD (\textit{Hot Filament Chemical Vapor Deposition}), utilizando como fonte de dopante uma solução de óxido de boro em metanol. A princípio, na primeira série de experimentos v

2. Degradação eletroquímica do cloranfenicol em reator de fluxo
This paper reports a study of electrochemical degradation of the chloramphenicol antibiotic in aqueous medium using a flow-by reactor with DSA® anode. The process efficiency was monitored by chloramphenicol concentration analysis with liquid chromatography (HPLC) during the experiments. Analysis of Total Organic Carbon (TOC) was performed to estimate the de

4. Estudo da degradação de ranitidina via H IND. 2 O IND. 2 eletrogerado/fenton em um reator eletroquimico com eletrodos de difusão / Studyof the degradation eletrochemical of ranitidine it saw H IND. 2 O IND. 2 eletrogerado/fenton in an eletrochemical reactor with electrodes of gaseous diffusion
The study of the electrochemical degradation of the ranitidine, a drug used in the therapy of gastric ulcers was development in two steps. In the first step was studied the electrochemical behavior of the ranitidine on platinum (Pt) and glassy carbon (CV) electrodes, using cyclic voltammetry in aqueous (K2SO4 0.1 M) and non-aqueous (NaClO4 0.1 M in DMF) elec

5. A study of steel bar reinforcement corrosion in concretes with SF and SRH using electrochemical impedance spectroscopy
Several electrochemical techniques can be used to monitor corrosion, among them are open circuit potential (OCP) and eletrochemical impedance spectroscopy (EIS). Monitoring OCP is the most typical procedure for routine inspection of reinforced concrete structures and can be easily carried out, however it only gives an approximate idea of the corrosion proces

7. Eletrochemical techniques for particulate system decontamination treatments. / Avaliação da técnica de eletroosmose na remoção de contaminante orgânico em meios particulados.
The use of electrochemical techniques is probably one of most promising technology for particulate system decontamination treatments. This methodology appears as able to remove heavy metals, radionucletides and organic and inorganic contaminations. By using an electric potential difference with low currents intensities through electrodes, the contaminants in

8. Eletrochemical treatament of the cyanide wastewater using commercial noble metal oxide electrodes / Tratamento eletroquimico de efluentes cianidricos usando eletrodos comerciais de oxidos de metais nobres
Inorganic cyanide is still in use in the metal finishing industry and in the mining activities of noble metals extraction and refining. Gold and silver are extracted from its ores as cyanidric complexes. The intensive industrial use of cyanide complexes is responsible for the generation of high toxicity aqueous streams, which present high oxygen demand. The
