Cyclic voltammetric studies were carried out on the deposition of polyaniline on pure aluminum from oxalic acid solution with and without different anions (CO3, SO3, SO4, DBS) and contribution of these anions to lyaniline film formation was investigated. Corrosion behavior of polyaniline coated aluminum in oxalic acid solution with and without different anions (CO3, SO3, SO4, DBS) has been inve...

Abstract: The aim of this bachelor project is to fabricate and study hybrid quantum dot (QD) devices featuring Yu-Shiba-Rosinov (YSR) sub-gap states, made on special InAs nanowires with 7 nm epitaxial aluminum coating on 3 facets. The advantage with these nanowires is the epitaxial aluminum, which can be etched away in a small window of semiconducting nanowire for creating QDs. These dots can b...

Abstract In order to investigate the anti-corrosion effect of coated steel bridge, Q345 plate specimens with three types coatings, including zinc coating, aluminum coating and zinc-aluminum are produced by arc spraying technology. present study, chlorine corrosion tests performed influence law different material its thickness on degree. Then calculation results two indicators compared analyzed....

PURPOSE The purpose of this in vitro study is to examine the effects of a nano-structured alumina coating on the adhesion between resin cements and zirconia ceramics using a four-point bending test. MATERIALS AND METHODS 100 pairs of zirconium bar specimens were prepared with dimensions of 25 mm × 2 mm × 5 mm and cementation surfaces of 5 mm × 2 mm. The samples were divided into 5 groups of 2...

In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...

0= 85° onto a smooth surface, such as glass, possessed a high absorption characteristic of an aggregated structure (Fig. 4.), but diffuse reflection was not present. When, however, a film of 2.7,ug/cm 2 was deposited at 850 onto an aluminum film (16,ig/cm), which had been deposited at normal incidence, a strong decrease in specular reflectivity for the blue was obtained. Both aluminum films wer...

Phenolic resin-derived activated carbon (AC) cloths are used as electrodes for large scale electric double-layer capacitors (EDLCs) or supercapacitors. To increase the energy and power density of the supercapacitor, the contact resistance between the carbon cloth and the aluminum foil current collector is reduced by modifying the Al current collectors. Different modified Al current collectors, ...

The purpose of this study is to analyze the quality optical properties such as energy band gap thin layer tin oxide doped with aluminum, fluorine, indium, aluminum-fluorine, aluminum-indium, and aluminum-fluorine-indium. was synthesized using sol-gel spin coating method. ratio basic ingredients doping used in 95:5% 85:15%. that has been formed then heated at a temperature 100 200 0C. results an...

Aluminum (Al) and Al alloys exhibit unusual passivity when immersed in alkaline lithium (Li) salt solutions. This passivity is a result of precipitation of a continuous, polycrystalline talc coating. Talc coatings persist when removed from the Li salt solution and offer increased corrosion protection during exposure to aggressive environments. Efforts to develop a low-cost, low-toxicity, easily...
