After nucleation, each dot was found to increase in sizes up to a critical transverse dimension, the process of pulsed electrodeposition of gold being continuously supported by the formation of new nanodots. The density of deposited Au dots is shown to be dependent upon the number and width of the applied voltage pulses. The deposition of \"size-saturated\" dots continues until the entire surface exposed to the electrolyte is covered by a monolayer of self-assembled Au nanodots.","PeriodicalId":11470,"journal":{"name":"ECS Electrochemistry Letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1149/2.0041504EEL","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64316421","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}

A Nickel based electrode was employed as the active catalyst. The effective rate of ammonia generation of the eU2A process at 70°C is ~28 times higher than the thermal hydrolysis (THU) of urea. The eU2A operates at lower temperature (55% lower) and pressure (6 times lower) than the THU; this could lead to significant energy savings. The process finds applications on selective catalytic reduction (SCR) for the removal of nitride oxide from combustion systems (e.g., diesel vehicles, power plants, etc.).","PeriodicalId":11470,"journal":{"name":"ECS Electrochemistry Letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1149/2.0041510EEL","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64316468","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}

So far, less emphasis has been focused on the employment of alternative magneticfield in electro-deposition, and all the relevant reports are about using alternative magnetic field as an electrochemical method, 5,9 rather than an engineering approach. The crucial difference between the alternative magnetic field and the static one in terms of the effect on electrodeposition is the induced electric field. The alternative magnetic field thus may produce some specific influences on the charged ions in the electrolysis system. Inthispaper,theeffectsofalternativemagneticfieldontheproperties of nickel electro-deposition were examined. The alternative magnetic field was generated by spinning permanent magnets. Special attention was paid to the relationship between the magnets’ rotating speed and the nickel deposit’s surface morphology and preferred orientation. The characterization of the deposited nickel was conducted by electrochemical tests, SEM, AFM, and XRD techniques.","PeriodicalId":11470,"journal":{"name":"ECS Electrochemistry Letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1149/2.0101506EEL","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64340321","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}
