2. Simultaneous Voltammetric Determination of Antihypertensive Drugs Amlodipine and Atenolol in Pharmaceuticals Using a Cathodically Pretreated Boron-Doped Diamond Electrode
The simultaneous voltammetric determination of antihypertensive drugs amlodipine besylate (AML) and atenolol (ATN) using a cathodically pretreated boron-doped diamond electrode (CP-BDDE) is reported for the first time. The anodic peak potentials of AML and ATN at a CP-BDDE were found to be 0.727 and 1.32 V (vs. Ag/AgCl (3.0 mol L-1 KCl)) in phosphate buffer

3. Boron Doped Ultrananocrystalline Diamond Films on Porous Silicon: Morphological, Structural and Electrochemical Characterizations
Boron doped ultrananocrystalline diamond (BDUND) films were grown and characterized on porous silicon (PS) substrates. PS samples were prepared from n-type monocrystalline silicon wafers (100) with 1-20 Ω.cm of resistivity, by electrochemical etching, using HF-acetonitrile solution as electrolyte. BDUND films were grown by Hot Filament Chemical Vapor Deposi

4. Desenvolvimento de biossensores utilizando nanotubos de carbono e nanopartículas de ouro / Development of biosensors using carbon nanotubes and gold nanoparticles
First, a glassy carbon electrode modified with functionalized carbon nanotubes (CNTs) and glucose oxidase was proposed. Cyclic voltammetry of GOx immobilized onto the surface of CNTs showed a pair of well-defined redox peaks, which corresponds to the direct electron transfer of GOx, with a formal potential of -0.418 V in 0.1 mol L-1 phosphate buffer solution

5. Desenvolvimento de eletrodos cilíndricos de diamante para tratamento de águas / Cylindrical diamond electrodes for wastewater treatment
Cylindrical diamond electrodes are developed with area up to 75 cm2 and were applied in electrochemical degradation of organic pollutants in wastewater. Systematic study was carried out to deposit conductive and well-adherent diamond onto several materials. These electrodes were characterized in term of their material and electrochemical properties by scanni

6. Phenol removal from wastewaters by electrochemical oxidation using boron doped diamond (BDD) and Ti/Ti0.7Ru0.3O2 dsa® electrodes
Industrial wastewater containing non-biodegradable organic pollutants consists of highly toxic effluents whose treatment is necessary due to environmental and economical restrictions. In order to treat these effluents, an electrochemical process using a dimensionally stable anode (DSA®) and boron-doped diamond (BDD) electrode was studied. The performance of

Esters of p-hydroxybenzoic acid, as methylparaben (MePa), ethylparaben (EtPa) and propylparaben (PrPa) have been widely used as chemical preservatives in cosmetics, drugs, foods, and others. As these compounds are linked with allergies, dermatitis and estrogenic properties, it is necessary to control the concentration of these substances in the different mat
