The surface and optical properties of black chrome films prepared by two different electrochemical baths were characterized. The black chrome films have been deposited on bright nickel substrates by electroplating technique. The surface morphology and phase structure of the films were investigated by using scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The chemica...

Garlic was fermented spontaneously in a water bath with temperature of 72 °C and relative humidity close to 90%. The fermentation periods were 0 (fresh garlic), 7, 14, 21 days. Several physicochemical properties: antioxidant capacity, total polyphenol, flavonoid content, pH, browning intensity determined. All the chemical properties black garlic increased significantly during fermentation, exce...

chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

New copper plating bath chemisties are being developed to meet the emerging need of plating copper into submicron features on semiconductor wafers. These chemistries are designed to provide a fast, efficient, fill for even the most challenging wafer terrain. It has been found that maintaining the concentration of the additives in these plating baths at certain levels is critical to the performa...

Ni-P and Ni layers multilayer coatings were applied to AZ31 magnesium alloy utilizing electroless and electrodeposition procedures. The aim of the project was to decrease cracks and increase corrosion resistance of the coatings. In order to compare the coatings, the effect of single layer electroless Ni-P coatings with different thicknesses was also investigated. The microstructure and phase co...

conclusions it is suggested that the training of nonpharmacological methods to improve sleep quality such as reflexology and foot bath be included in the elderly health programs. in addition, it is recommended that the impact of these interventions on subjective sleep quality using polysomnographic recordings be explored in future research. background sleep disorders are common mental disorders...

In an attempt to control the film composition, factors affecting the composition of Ni-Fe alloy deposits and their crystal structure have been analyzed as a function of bath composition, cathode current density, bath pH, temperature and an addition of citric acid. antimony electrode revealed that the deposition potential of Fe coincides with the potential where the abrupt increase of pH was obs...
