1. Experimental-numerical Technique to Evaluate the Thickness of TiN Thin Film
In this study, the numerical analysis of instrumented indentation testing was combined with the experimental procedure to evaluate the mechanical properties and thickness of a titanium nitride (TiN) film deposited on titanium substrate (Ti) by plasma processing. TiN film thickness is an important parameter for the surface treatment industry. In numerical ana

2. ITO Obtained by Spray Pyrolysis and Coating on Glass Substrate
Conductive thin films have various applications in different technological fields. Indium tin oxide (ITO) is a mixed oxide. In the film form, ITO has been widely employed as electrode in many optoelectronic devices. Methods like thermal evaporation, sputtering, chemical vapor deposition (CVD), electron beam, spray coating, and sol-gel synthesis give ITO thin

3. Corrosion Mechanism Suggested Based on Electrochemical Analysis and SVET for Uncoated Tinplate and Post Coated With a Hybrid Film
The tinplate, used in the packaging sector and formed from a metal substrate, comprises a steel base which has undergone a surface treatment to produce a thin layer of FeSn2, a tin layer and an oxide tin layer. Currently, packaging using surface treatment is based on the use of chromates because these metals provide an excellent corrosion resistance. Nontoxi

4. Investigation of borided layers contribution on the wear resistance and adhesion of TiN coatings
ABSTRACT The purpose of the investigation was to examine the possibility of improving tool life by reducing the wear effect and improving the adhesion of a thin film through a compound configuration that consists in boriding and PVD deposition. Single layer coatings of TiN were deposited by PVD (cathodic arc) on quenched and tempered and on borided powder me

6. Electrochromic Properties of Polyaniline-Based Hybrid Organic/Inorganic Materials
Hybrid materials based on polyaniline (PAni) were obtained by in situ polymerization of aniline with chitosan and/or organically modified clay (nanomer I-24) in HCl. The samples were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and direct current (DC) electrical conductivity. Thi

7. Thin Tin and Tio2 Film Deposition in Glass Samples by Cathodic Cage
Thin nitride and titanium dioxide films were produced using an innovative technique called cathodic cage depositon. Uniformity, three-dimensionality and high rate deposition are some of the advantages of this technique. In this study we discuss the influences of temperature, treatment time and gaseous atmosphere on the characteristics of the deposited films.

8. Influência dos parâmetros de processo na deposição de nitreto de titânio por plasma em gaiola catódica
Filmes finos de nitreto de titânio foram crescidos sobre vidro utilizando a técnica de deposição por descarga em gaiola catódica a fim de averiguar a influência das variáveis de processo nas propriedades ópticas e estruturais do filme. Como atmosfera do plasma foi utilizada a mistura de gases Ar, N2 e H2, fixando o fluxo de Ar e N2 em 4 e 3 sccm, res

9. Preparação e caracterização eletroquímica de filmes finos de nanotubos de carbono depositados sobre ITO / Preparation and electrochemical characterization of thin films of carbon nanotubes deposited on ITO
In this work were carried out some studies on electrochemical properties of carbon nanotubes (CNT) thin films deposited on ITO (Indium Tin Oxide) electrodes by electrophoretic deposition (EPD). Capacitance and electrochemical area measurements were made with films of three types of nanotubes with different dimensions and previous treatments. All measurements

10. Construção e caracterização de célula solar tipo barreira Schottky CdTe/Al / Construction and caracterization of Schottky barrier solar cells CdTe/Al
In this work the techniques of hot wall epitaxy (HWE) and molecular beam epitaxy (MBE) on thin films of CdTe (cadmium telluride) were used in order to manufacture a prototype solar cell type Schottky barrier. The films were produced by evaporation of a solid alloy of CdTe, varying two parameters of deposition: the growth time and substrate temperature. In th

11. Influence of pH of colloidal suspension on the electrical conductivity of SnO2 thin films deposited via Sol-Gel-Dip-Coating
Tin dioxide (SnO2) thin films are deposited by the dip-coating technique from colloidal suspensions prepared with distinct pH through the sol-gel method. The decrease of the pH contributes to the destruction of an electrical layer adjacent to particles in solution, leading to a high degree of aggregation among these particles due to the generation of cross-l

12. Desenvolvimento de uma metodologia de fabricação de transistores de filmes finos orgânicos. / Development of a manufacturing methodology for organic thin film transistors.
In this work, it is presented a methodology for organic thin-film transistor (OTFT) fabrication. Poly(3-hexylthyophene) (P3HT):[6,6]-phenyl-C61-butyric acidmethyl ester (PCBM) bulk heterojunction solar cells were studied for their maximum power conversion efficiency (PCE) around 5 %. Efficiencies evolution in time from 10-6 to 1.7 % show the difficulties inv
