25. Analysis of the chemical bath and its effect on the physical properties of CdS/ITO thin films
Cadmium sulphide (CdS) thin films deposited on indium tin oxide (ITO) substrates were prepared by the chemical bath deposition technique at different values of pH and pNH3. This was made in order to analyze the influence of the initial chemical composition of the bath on some physical properties of the final CdS films, used as optical windows for solar cells

26. NanocompÃsito montmorilonita/polipirrol: preparaÃÃo,caracterizaÃÃo e aplicaÃÃo como sensores de volÃteis
Clay/polymer nanocomposites have been sufficiently studied during some time because they could be used in industrial applications. Clay is a Phyllosilicate Subclass Mineral, it is formed by sheets, layers or lamels and has a Tetrahedron- Octahedron-Tetrahedron (TOT) like structure with free hydroxile and cations between the lamels and on the surface. In this

27. Synthesis and determination of the electron affinity, ionization potential and energy of band prohibited of electroluminescent polymers / Síntese e determinação da afinidade eletrônica, potencial de ionização e energia de banda proibida de polímeros eletroluminescentes
In this work we describe the electrochemical and optical aspects of a series of electrochemically synthesized blue-electroluminescent conjugated polymers. The materials employed here comprised poly(p-phenylene) (PPP), poly(pyrro1e) (PPI), poly(3-methylthiophene) (P3MET), poly(p-pheny1ene-pyrrole) (CPPI) copolymer and poly(p-phenylene3methyIthiophene) (CP3MET

28. Study of catalytics Pt-In/Nb2O5 in the hydrocarbons conversion / Estudo de catalisadores Pt-In/Nb2O5 na conversão de hidrocarbonetos
Hydrocarbon dehydrogenation is an important industrial process, due to the high demand of unsatured hydrocarbons for industrial processes and products. Unsatured hydrocarbons are used in the manufacture of several products, such as detergents, high octanage gasoline, pharmaceutical products and synthetic rubber. The commercial catalysts employed in the hydro

29. Dióxido de titânio sol-gel: propriedades e comportamento eletrocrômico
Titanium dioxide was prepared by hydrolysis and polycondensation of titanium tetraisopropoxide. TiO2 films were obtained by spin coating of the precursor solution on ITO substractes (glass covered with indium doped tin oxide). Films were prepared using different temperatures and hydrochloric acid contents. The effect of the drying temperature of the films (1

30. Indium-cadmium-oxide films having exceptional electrical conductivity and optical transparency: Clues for optimizing transparent conductors
Materials with high electrical conductivity and optical transparency are needed for future flat panel display, solar energy, and other opto-electronic technologies. InxCd1-xO films having a simple cubic microstructure have been grown on amorphous glass substrates by a straightforward chemical vapor deposition process. The x = 0.05 film conductivity of 17,000

31. Electrically conducting polymers can noninvasively control the shape and growth of mammalian cells.
Electrically conducting polymers are novel in that their surface properties, including charge density and wettability, can be reversibly changed with an applied electrical potential. Such properties might render conducting polymers unique for biological applications. However, the majority of research on conducting polymers has been carried out under nonbiolo

32. Stimulation of neurite outgrowth using an electrically conducting polymer
Damage to peripheral nerves often cannot be repaired by the juxtaposition of the severed nerve ends. Surgeons have typically used autologous nerve grafts, which have several drawbacks including the need for multiple surgical procedures and loss of function at the donor site. As an alternative, the use of nerve guidance channels to bridge the gap between seve
