Study of atmospheric particulate matter in Buenos Aires city
Abstract The data reported here constitute the results of the first long-term monitoring campaign of daily PM10 and PM2.5 concentration levels in Buenos Aires city. Twenty-four hour averages… Expand
Layer-by-Layer Self-Assembly of Glucose Oxidase with a Poly(allylamine)ferrocene Redox Mediator
We report the redox mediation of glucose oxidase (GOx) in a self-assembled structure of cationic poly(allylamine) modified by ferrocene (PAA-Fc) and anionic GOx deposited electrostatically… Expand
Surface electrochemical transformations on spinel iron oxide electrodes in aqueous solutions
The effect of potential and electrolyte composition on the surface stoichiometry in magnetite oxide electrodes has been investigated by a variety of electrochemical techniques: open-circuit… Expand
Nanowire manipulation on surfaces through electrostatic self-assembly and magnetic interactions
A method for fabricating aligned nanowire arrays on surfaces is shown. Gold and segmented Au/Ni/Au nanowires of high aspect ratio have been prepared by template electrosynthesis, and functionalized… Expand
