AIEM-0.6, AIEM-1.4 and AIEM-2.0 were obtained via solution-casting method. Quantum calculation and experiments verified the selective permeability of the membranes: high proton conductivities and low vanadium permeation parameters. Also the AIEMs demonstrate good acid resistance and thermal stability, showing potential in vanadium redox flow battery (VFB) fields.","PeriodicalId":11470,"journal":{"name":"ECS Electrochemistry Letters","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1149/2.0081410EEL","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64332528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both sides of each specimen sheet were ground and flattened until 0.05-0.80 mm by mechanical polishing finally using colloidal silica particles of 0.05 μm. The thickness variation of speci- men sheet was controlled within 5%. The back side was electroplated with a nickel layer of 0.5 μm in thickness by cathodic polarization at 0.1 A cm −2 in a Watt's bath (1 mol dm −3 NiSO4 + 0.2 mol dm −3 NiCl2 + 0.6 mol dm −3 H3BO3) at 323 K. Fig.1is a schematic diagram of a Devanathan-Stachurski cell used in this study. The specimen sheet was sandwiched between the two electrochemical cells made from acrylic glass with two O-rings and connected with two potentiostats as working electrodes. The front and back sides of the sample sheet served as hydrogen entry and exit electrodes, respectively. Each cell had a platinum counter electrode and an Ag/AgCl/saturated KCl reference electrode with a Luggin- Haber capillary. The electrolyte in both cells was pH 8.4 boric-borate buffer solution deaerated by bubbling pure Ar gas. The electrolyte in the hydrogen entry side cell was flowed by using a bimorph pump at a constant or sinusoidally pertubated volume flow rate in the range of 0.145-1.50 cm 3 s −1 , while the electrolyte in the cell for the hydrogen exit side was stagnant. During the potentiostatic polarization of entry and exit electrodes, currents flowing through both electrodes were recorded with the electrolyte flow rate using a PC controlled by a LabVIEW (National Instruments) program.","PeriodicalId":11470,"journal":{"name":"ECS Electrochemistry Letters","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1149/2.011406EEL","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64347022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanowire morphology was achieved by using an anodic alumina membrane having cylindrical pores of similar to 200 nm diameter. Compositional analysis at a single nanowire level revealed a fairly uniform distribution of component elements in the nanowire volume. Structural characterization strongly indicated toward a presence of randomly oriented, non-equilibrium, nano-crystalline phase volume inside the nanowires. Magnetic characterization revealed a soft magnetic character for the as-synthesized Ag-Ni-Fe nanowires. (C) 2014 The Electrochemical Society.
