Magnetic Tuning of the Electrochemical Reactivity through Controlled Surface Orientation of Catalytic Nanowires

Abstract: Nanowires have received considerable attention owing to their broad potential applications. We report here on the application of nanowires for magnetic control of the electrochemical reactivity and demonstrate how one can modulate the electrocatalytic activity by orienting catalytic nanowires at different angles. Unlike early "on/off" magnetic switching studies based on functionalized magnetic spheres, the present magnetoswitchable protocol relies on modulating the electrochemical reactivity without removing t… Show more

“…One type of MR materials are the composites formed by dispersing magnetic filler particles into an elastomer polymeric matrix, referred as magnetorheological elastomers (MRE) [1][2][3]. A simple procedure to obtain MRE materials is curing the filler-elastomer composite in the presence of a uniform magnetic field (H curing ) which induces agglomerations of the filler particles into chain-like structures aligned in the direction of the field [4][5][6][7][8][9][10][11].…”

“…[3] Como qualquer tecnologia em desenvolvimento, a microfluídica parece muito boa para ser verdade: ofececem muitas vantagens e poucas desvantagens (pelo menos em análise química onde está sua principal aplicação). Entretanto, ainda não se tornou amplamente utilizada.…”

“…Assim, as respostas para questões relacionadas ao tempo e circunstâncias necessárias para o desenvolvimento dos sistemas analíticos miniaturizados em uma nova e popular tecnologia são importantes não somente para seu próprio campo, mas também para outras novas tecnologias que vêm lutando para atingir o mesmos objetivos. [3] A microfluídica possui quatro áreas principais correlacionadas que serviram e continuam servindo de impulso para o desenvolvimento de novas tecnologias:…”
