About this collection
We are delighted to share with you a selection of the papers associated with a Faraday Discussion on Next Generation Nanoelectrochemistry. More information about the event may be found here: http://rsc.li/electrochemistry-fd2021. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the discussions will be published after the event.
Nanoelectrochemistry is important not only for achieving ultra-sensitive applications in fields ranging from energy to bioanalysis, but also contributes to more fundamental understanding of processes on this scale. While electrochemical processes occur within confined geometries at the nanometre scale, electrochemistry endows us with an ever-increasing ability to measure and understand with unprecedented precision, creating enormous opportunities.
This Faraday Discussion meeting address the challenges in both fundamental and applied nanoelectrochemistry where new concepts and new knowledge play key roles. This meeting also encourages cross-disciplinary interactions for electrochemistry with biophysics, nanofabrication, informatics, electronics and beyond.
At this Faraday Discussion, we will discuss new concepts and knowledge within the field of nanoelectrochemistry, including the new methods and novel applications. These new methods for achieving high precise electrochemical measurement at nanoscale, make it possible to provide fundamental electrochemical concept/tool/techniques to integrate with advanced spectroscopy and informatics technology to achieve real-life applications.
