Hybrid solar cells show an increasing number in researches due to its low cost and easy of production. They are composed by organic material a semiconductor oxide. The aim this paper was synthesis characterize zinc oxide coprecipitation apply it hybrid cell that uses P3HT/P3OT copolymer as charge carrier. assembled "sandwich" form using FTO/ZnO/P3HT-P3OT work electrode, (Pt/FTO) conter electrode I/I-3 redox couple electrolyte. Through the X-ray diffractogram formation single ZnO wutzite...
Purpose The purpose of this paper is to evaluate the protection against corrosion carbon steel SAE 1020 promoted by a niobium- and titanium-based coating produced from resin obtained Pechini method. Design/methodology/approach A was prepared with ammonium niobium oxalate as precursor K 2 TiF 6 titanium precursor. Carbon Steel plates were dip coated in calcinated for 1 h at 600 ºC. Scanning electron microscopy, energy dispersive spectroscopy X-ray diffraction used characterize morphologically...
Duplex stainless steels are widely used due to their good mechanical properties and corrosion resistance. However, they susceptible microstructural fragility related harmful transformations taking place in intermetallic phases, such as the sigma phase. These reduce like toughness The current study aims analyze effect of different thermodynamic- electrochemical-reactive phases based on using both linear sweep voltammetry tests non-destructive tests, well concept microelectrodes. This...
The lead produced in Brazil comes entirely from the lead-acid battery recycling industry. During process, 100 to 350 kg of slag is generated for each ton metallic produced. This large amount waste causes serious environmental problems, where reuse and reducing toxicity are measures resolve its negative impact. Thus, work methodology adopted was a bibliographic survey addressing process (pyrometallurgy), presenting data, discussing slag, generation, physical chemical characteristics, possible...
Carbon steel is widely used in the industry due to its mechanical properties and low cost, but contrast it resists poorly corrosion, leading economic losses issues. The use of surface treatment essential extend life metallic material. In this context, niobium being studied for great corrosion resistance properties. aim paper was produce evaluate protection a niobium-based coating produced by Pechini Method. resin applied dip-coating then calcinated at 450 oC 1 hour. coated material analyzed...
Carbon steel is one of the most used metal alloys in industrial applications due to its low cost when compared other metallic materials.However, use may be limited tendency corrode.Thus, it necessary develop methods that inhibit degradation.One way reduce corrosion through inhibitors, which are generally organic compounds and can act by adsorption form protective films.Some with heteroatoms such as O, N, S forming a film.However, some inhibitors has been their harmful effect on...
