1. Pulse Eletrodeposition of Ni/nano-Al2O3 Composite Coatings on Cast Iron Cylinder Liner
Ni/nano-Al2O3 composite coating by pulse electrodeposition method has been used for coating on cast iron liner material. The hardness has been increased from 308 HV to 1050 HV through conventional Watts bath and by applying Taguchi's optimization technique with optimum parameters of pulse frequency 120 Hz, duty cycle 40% and peak current density 0.7A/cm2. Th

2. REMOÇÃO DE ÍONS ZINCO (II) DE EFLUENTES DERIVADOS DE PROCESSOS DE GALVANOPLASTIA UTILIZANDO REJEITOS DE FIBRAS VEGETAIS MODIFICADAS QUIMICAMENTE
Many industrial activities contribute to a significant increase in the concentrations of metal ions in natural waters by not adhering to an appropriate treatment in accordance with the standards established by the legislation. The applicability of new methods of costbenefit has been developed in order to facilitate a system of treatment for removal of contam

3. Galvanostatic electrodeposition of cadmium telluride on monocrystalline Silicon (111) / Eletrodeposição galvanostática de telureto de cádmio sobre silício monocristalino (111)
No presente trabalho, estudamos filmes finos de CdTe eletrodepositados galvanostaticamente em meio aquoso ácido (pH<1) sobre silício monocristalino, tipo-n, (111). A densidade de corrente de 0,3 mA/cm2 permitiu a obtenção de filmes de melhor qualidade. Os filmes foram caracterizados por microscopia eletrônica de varredura (SEM), difração de raios-X (X

4. Gravação e caracterização de nanoestruturas bidimensionais em relevo
This thesis describes the recording of two dimensional surface-relief nano structures, using double holographic exposures and lithography. The experimental conditions for recording photoresist masks are described, as well as for the lithography of the two dimensional pattern in three different materials: aluminum, nickel and hydrogenated amorphous carbon.
