View Original Abstract
This Special Issue contains a collection of papers from the 2015 E-MRS Fall Meeting (European Materials Research Society), Symposium R entitled “Nanocarbon Electrochemistry and Interfaces”. The meeting was held September 15-18 in Warsaw, Poland. Approximately 60 scientists and students from 11 countries participated in the symposium. There were 9 invited talks, 22 oral presentations and 27 posters presented during the 2.5 day symposium. This symposium focused on the material properties, electrochemical behavior and electrochemical application of novel carbon materials including diamond, carbon nanotubes (CNTs), graphene, graphene oxide, carbon fiber, carbon onions, porous carbon, carbon black, carbon/diamond nanoparticles, carbon nitride, silicon carbide and their nanocomposites. Applications of these nanocarbons in electroanalysis, biosensing, electrocatalysis, electrosynthesis, environmental degradation, energy conversion and storage were covered.1 This Special Issue contains 5 reviews and 27 original research papers. The reviews include (i) recent progress with nanocarbon electrodes and electroanalytical applications, (ii) electrochemical grafting and surface functionalization of carbon electrodes for electroanalytical applications, (iii) the use of graphene for immunosensors, (iv) bioelectroanalytical applications of carbon nanoparticles, and (v) diamond-based scanning probe microscopic tips. Among 27 original research papers, 5 papers focus on the electrochemical properties of carbon materials, 18 papers are about the sensor development using nanocarbons, and 4 papers are devoted to electrochemical applications of nanocarbons. We believe this Special Issue will bring the readership up to dateabout progress with preparation and characterization of nanocarbons and their emerging applications in electrochemistry. The content will hopefully stimulate new ideas for nanocarbon-based materials in electroanalytical chemistry and facilitate interactions between material scientists, chemists, biochemists, physics, and engineers working in the field. 1 1
