Reaction Kinetics and X-Ray Absorption Spectroscopy Studies of Yttrium-Containing Metal Hydride Electrodes
This is a study of electrode degradation mechanisms and reaction kinetics of LaNi4.7Sn0.3, La(12x)YxNi4.7Sn0.3 (x 5 0.1, 0.2, and 0.3) and La0.7Y0.3Ni4.6Sn0.3Co0.1 metal hydride electrodes. Alloy characterization included X-ray diffraction, X-ray absorption (XAS), hydrogen absorption in a Sieverts apparatus, and electrochemical cycling of alloy electrodes. The atomic volume of H was determined ...
متن کاملAtomic Absorption Spectrometric Determination of Lead after Extraction and Preconcentration with 5-Br-PADAP
Lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. After filtration, the solid mass consisting of the lead complex and naphthalene was dissolved wi...
متن کاملElectrochemical Deposition of γ-Phase Zinc-Nickel Alloys from Alkaline Solution
Zinc-nickel alloys with 8-15% nickel were deposited onto stainless steel for corrosion protection. Alkaline deposition conditions were utilized given that alkaline systems have been found to offer superior substrate coverage which results in better corrosion protection of the metal substrate (stainless steel) compared to acid bath depositions. This method utilizes ammonium hydroxide as the base...
متن کاملOutstanding resistance and passivation behaviour of new Fe-Co metal-metal glassy alloys in alkaline media
The electrochemical behavior of the oxide layers on two metal-metal glassy alloys, Fe78Co9Cr10Mo2Al1 (VX9)and Fe49Co49V2 (VX50) (at.%), were studied using electrochemical techniques including electrochemical frequency modulation (EFM), electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP) measurements. The morphology and composition of the alloy surfaces were investigated us...
متن کاملبررسی و مقایسه زیستسازگاری آلیاژ مینالوکس و آلیاژ مشابه خارجی (In-vitro)
Statement of Problem: One of newly presented base metal alloys (Minalux) is produced according to VeraBond2 alloy (Ni- Cr base) composition. Several studies showed that, cytotoxicity of base metal alloys can be occurred due to corrosion and element release. Purpose: This study evaluated the biocompatibility of these two base metal alloys in three steps: as cast, after polishing and after porcel...
