Graphene — A Physical Chemistry Perspective surface-modified carbon nanostructures.4-6 Scanning tunneling microscopy (STM) of epitaxial graphene (EG) doped by organic free radicals revealed that the empty density of states near the adsorption site significantly decreased as a result of radical doping.7 Modified electronic structure arising from the interaction between Pt clusters and the HOPG surface was shown to reduce the CO adsorption energy.8 A self-assembly method was used to fabricate large-area multicomponent hybrid films with a well-defined architecture and tunable thickness on various substrates for electrochemical applications.9
JPC Letters was launched earlier this month with impressive contributions from researchers from around the world. We are delighted with the enthusiasm shown by the scientific community and look forward to continued success in the year ahead. Each issue of the journal will feature Perspectives on one or two emerging research themes. Perspectives published in JPC Letters provide a platform to disseminate state of the art research in emerging areas of physical chemistry, chemical physics, and material science. Often, Perspectives will be accompanied by a short video. The first such video by Prof. Franz M. Geiger and his student Ms. Stephanie R. Walter was posted on the journal webpage (http://pubs.acs.org/journal/ jpclcd) recently.
Our streamlined editorial process will continue to provide fast publication time and immediate availability of the complete citation of all ASAP articles.
Perspectives published in JPC Letters provide a platform to disseminate state of the art research in emerging areas of physical chemistry, chemical physics, and material science.
On behalf of all of the editors, I would like to take this opportunity to thank our authors and readers for making the launch of the new journal so successful. Our streamlined editorial process will continue to provide fast publication time (4-6 weeks from time of submission to publication) and immediate availability of the complete citation of all ASAP articles. We look forward to working with the physical chemistry community, publishing the highest-quality scientific papers, and providing the greatest impact to our authors' published work.
The Perspectives in this issue focus on graphene-based architectures and the opportunities they offer in developing next-generation electronic and energy conversion devices. For the past several decades, carbon-based systems have contributed significantly to the development of sensors, catalysts, and power sources. The recent emergence of graphene has drawn the attention of many researchers toward exploring the unique properties of two-dimensional carbon nanostructures. Exfoliation of graphene sheets from graphite is a convenient and economically viable approach that enables solution processing and chemical functionalization of two-dimensional carbon nanostructures. Green and Hersam1 discuss graphene dispersions with tailored thickness, lateral area, and shape. The technique of density gradient ultracentrifugation is useful in separating graphene sheets with different thicknesses, thus enabling the study of structural parameters in a systematic fashion. The possibility of utilizing reduced graphene oxide as a two-dimensional carbon support to anchor semiconductor and metal nanoparticles is also discussed.2 Such an approach provides a new way to develop multifunctional catalyst mats with tailored properties. Rao and co-workers3 highlight electronic, optical, and magnetic properties of graphene-based systems. These Perspectives discuss the potential applications of graphene in energy conversion devices such as solar cells and batteries, as well as in catalysis, and the challenges that lie ahead. In addition, the Letters in this issue present new and interesting properties of graphene and related carbon nanostructures. Density functional theory calculations provide valuable insight into the structural and electronic properties of
