Printedonacid-freepaper SpringerispartofSpringerScience+BusinessMedia(www.springer.com) Preface Carbon nanostructures, or nanocarbons (CNSs), i.e. the low-dimensional nanoma- terialsthatcomprise0Dfullerenes,1Dnanotubesand2Dgraphene,haveemerged over the last two decades in the field of new molecular materials for their unique structuralandelectronicproperties,promptingahugeinterestworldwidebothfrom the viewpointof fundamental research and for their application in molecular elec- tronics,materialsscience,energystorageandconversion,biomedicine,sensingand biosensing. The electronic properties of CNSs and their optical, spectroscopic and electrochemical behaviour depend markedly on their characteristic nanometric dimensions;theidentificationofspecificquantitiesrelativetoindividualnanostruc- turesinthebulkphasehasprovedchallengingandhasrequiredextremeingenuity. Making solutions (or suspensions) of CNSs where the nanostructures could retain most of their pristine properties has been a prerequisite for either fundamental investigation or for the development of any viable technological exploitation of such properties. This was the case, for example, of the application of bandgap fluorescence spectroscopy of aqueous, micelle-like suspensions of single-walled carbon nanotubes (SWNTs) that has given access to the electronic energies of individualsemiconductingSWNTsasafunctionofstructurediameterandhelicity. Insuchacontext,thechapter“SolubilizationofFullerenes,CarbonNanotubesand Graphene” by AlainPe´nicauddescribes thevarious ingeniousapproaches tosolve the solubility issue and describes in particular how graphite, and modern nanocar- bons, can be made soluble by reductive dissolution. A large part of the present volumeconcernsthemergingofnanocarbonswithnanotechnologyandtheirimpact on technical development in many areas. Fullerenes, carbon nanotubes, nanodia- mond and graphene find, for instance, various applications in the development of solarcells,includingdyesensitizedsolarcells.Thechapter“IncorporationofBalls, TubesandBowlsinNanotechnology”byJamesMackdescribestherecentdevelop- ment of the area of fullerene fragments, and corannulene in particular, and their directapplicationstoorganiclightemittingdiode(OLED)technology,while,inthe chapter“ExploitingNanocarbonsinDye-SensitizedSolarCells”byLadislavKavan, the exploitation of nanocarbons in the development of novel dye sensitized solar cellswithimprovedefficiency,durabilityandcostsisthoroughlyreviewed. v vi Preface ThefunctionalizationofCNSshastheinvaluableadvantageofcombiningtheir uniquepropertieswiththoseofotherclassesofmaterials.Supramolecularchemis- try represents an elegant alternative approach for the construction of functional systems by means of noncovalent bonding interactions. In the chapter “Supramo- lecular Chemistry of Carbon Nanotubes” by Gildas Gavrel et al., the incredibly varied world of supramolecular, non-covalent functionalization of carbon nano- tubesandtheirapplicationsisexaminedandreviewed,andthesyntheticstrategies devised for fabricating mechanically-linked molecular architectures are described inthechapter“Fullerene-StopperedBistableRotaxanes”byAurelioMateo-Alonso, which presents an overview of the different types of fullerene-stoppered bistable rotaxanes,theirswitchingmechanismandtheirpotentialapplications. Inthechapter“Catalysis-MaterialCrosstalkatTailoredNano-CarbonInterfaces” by Michele Melchionna et al., carbon nanomaterials are described as supports for molecular and nanostructured catalysts, where their outstanding electronic and opticalproperties,highsurfaceareaandthermalandmechanicalstabilitycontribute tocreateasynergisticeffectthatleadstoenhancedperformanceforawiderangeof possibleapplications.Exploitationofnanocarbonsinbiologyandbiomedicalappli- cations has been increasingly proposed and, in particular, the chapter “Carbon Nanotubes in Tissue Engineering” by Susanna Bosi et al. explores applications of CNTsfortissueengineeringpurposes,wherethetubesprovedtobeidealmaterials forthegrowthandproliferationofmanykindoftissues. Thelocalchemicalreactivity,themechanicalpropertiesandtheelectrontransfer ingraphenemembraneshavebeenshowntobestronglyaffectedbythefold-induced curvature; thus in the chapter “Folds and Buckles at the Nanoscale: Experimental andTheoreticalInvestigationoftheBendingPropertiesofGrapheneMembranes”by Vittorio Morandi, a novel methodologytoinvestigate the mechanicalpropertiesof foldedandwrinkledgraphenecrystals,whichcombinetransmissionelectronmicros- copymappingandtheoreticalmodelling,isdescribed.Grapheneandnanocarbonsin general are intensively investigated as platforms for the development of sensing devicesfortheselectiveandhighlysensitivedetectionofbiohazards.Theaimofthe chapter “Graphene and Graphene Oxide Materials for Chemo- and Biosensing of ChemicalandBiochemicalHazards”byPiyushSindhuSharmaetal.isthentobring out important advances of graphene-based sensors, with particular attention to the rapiddetectionandquantizationoftoxins,explosives,pesticidesandpathogens. Becauseoftheseveralanddiversetechnologicalapplicationssofarproposed,and of the many more expected in the near future, the present volume is addressed to researchersfromseveraldifferentareas:chemistryandmaterialschemistry,nanotech- nology,medicineandindustrialresearch.Wehopetheywillenjoythepresentations andfindinspirationfortheirresearchactivityinthefascinatingfieldofnanocarbons.
