Sonoelectrochemical synthesis of ultrafine copper deposits at ambient and sub-ambient temperatures

Abstract

There is quiet revolution going on, and its name is nanotechnology. Without much fanfare, a host of innovations are coming our way. Use of electrochemistry, the solid/liquid interface science, in nanoscience and nanotechnology may range from
nanosystems, to nanosynthesis, to nanocharacterisation. The characteristic reaction may be ion transfer reaction (ITR) or electron transfer reaction (ETR).The nanoscale electrochemistry covering from metallic and semiconductor based nanoparticles,nanoarrays,nanotubes,nanopits, to self assembled molecule monolayers i.e. bioelectrochemical systems with redox metalloprotein or DNA based molecules, has began to unravel the complexities of these systems. Electrochemistry is a suitable method for coupling particles activity to external circuitry. It has been successfully used in investigating the effects and kinetics of charge transfer at Q-dots using scanning electrochemical microscopy (SECM), by controlled transport reactions. Electrochemical processes i.e. reaction at solid/ liquid interface controlled by an externally applied voltage, are increasingly involved in nanostructured fabrication as a relatively inexpensive superior quality products, easy to handle and a reliable tool.
