Autonomous nanomotor based on copper-platinum segmented nanobattery.

چکیده
We describe an efficient, bubble-free nanoscale motor consisting of a copper-platinum (Cu-Pt) segmented rod that operates as a nanobattery in dilute aqueous Br(2) or I(2) solutions. The motion of the rod is powered by self-electrophoresis caused by redox reactions occurring on the two different metal segments. Asymmetric ratchet-shaped pure copper nanorods were also found to rotate and tumble in aqueous Br(2) solution because of the ion gradient arising from asymmetric dissolution of copper.

Development of a Bio-nanobattery for Distributed Power Storage Systems
Currently available power storage systems, such as those used to supply power to microelectronic devices, typically consist of a single centralized canister and a series of wires to supply electrical power to where it is needed in a circuit. As the size of electrical circuits and components become smaller, there exists a need for a distributed power system to reduce Joule heating, wiring, and t...
متن کاملDynamic Loading and Unloading of Proteins in Polymeric Stomatocytes: Formation of an Enzyme-Loaded Supramolecular Nanomotor.
Self-powered artificial nanomotors are currently attracting increased interest as mimics of biological motors but also as potential components of nanomachinery, robotics, and sensing devices. We have recently described the controlled shape transformation of polymersomes into bowl-shaped stomatocytes and the assembly of platinum-driven nanomotors. However, the platinum encapsulation inside the s...
متن کاملElectrosynthesized Reduced Graphene Oxide-Supported Platinum, Platinum-Copper and Platinum-Nickel Nanoparticles on Carbon-Ceramic Electrode for Electrocatalytic Oxidation of Ethanol in Acidic Media
In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...
متن کاملAn improved autonomous DNA nanomotor.
DNA nanomotors are synthetic biochemical devices whose motion can be controlled at the molecular scale. Some DNA devices require several exogenous additions of different types of fuel to operate, which limits their potential uses. However, several devices that operate autonomously have recently been described. One such DNA nanomotor, based on a 10-23 DNA enzyme (DNAzyme), was introduced by Chen...
متن کاملEffect of platinum on Ceria supported Cu catalysts for PrOx process in fuel processors
The CO preferential oxidation (PrOx) is one of the critical steps in hydrogen production and purification for Polymer Electrolyte Membrane Fuel Cell (PEMFC). This reaction was investigated in the presence of excess hydrogen over Cu/CeO2, Pt/CeO2 and Cu-Pt/CeO2 catalysts. The ceria supports was prepared via precipitation method and Cu-Pt/CeO2 catalyst was synthesized by sequential impregnation o...
