Graphene, a single layer of carbon atoms forming a perfectly stable and clean two-dimensional crystal with very few defects, has been proclaimed to be a new revolutionary material for electronics. These hopes rest mainly on the unique band structure properties of graphene. 22 March 2010
Carbon nanotubes bridge the molecular and crystalline quantum worlds, and their extraordinary electronic, mechanical and optical properties have attracted enormous attention from a broad scientific community. 22 March 2010
Graphene has been considered by many as a revolutionary material with electronic and structural properties that surpass conventional semiconductors and metals. 20 March 2010
New electronic devices such as touch screens, flexible displays, printable electronics, solid-state lighting and thin film photovoltaics have led to a rapidly growing market for flexible transparent conductors. 20 March 2010
Graphene-based sheets such as graphene, graphene oxide and reduced graphene oxide have stimulated great interest due to their promising electronic, mechanical and thermal properties. 20 March 2010
The first issue that we address and justify in this paper is the pejorative and provocative tone of the title; the contradictory data on the toxic effects of single-walled carbon nanotubes (SWCNT) make us believe that it is appropriate and necessary. 16 February 2010
Are you on Facebook? Twitter, perhaps? Maybe LinkedIn? What about a social networking site dedicated to materials science? If you are not, you may be more alone than you think… 16 February 2010
The limits of silicon capabilities are being reached, coincidently, the discovery of graphene with its unique nano-scale properties is paving the way to possible substitutes for the next generation of faster and smaller electronics in 21st century. As a result of the promising properties of graphene, the research in the field is attracting large grants and sponsors with an incremental rise in the number of papers. The trends in graphene research are presented here. The major challenges in the field are pointed out, and some possible prospects in the field are discussed. 26 October 2009
Nature is the best example of a system functioning on the nanometer scale, where the involved materials, energy consumption and data handling are optimized. Opening the doors to the nanoworld the emergence of the scanning tunneling microscope in 1982 and the atomic force microscope in 1986 led to a shift of paradigm in the understanding and perception of matter at its most fundamental level. 24 August 2009
