Anomalies in thickness measurements of graphene and few layer graphite crystals by tapping mode atomic force microscopy
Atomic Force Microscopy (AFM) in the tapping (intermittent contact) mode is a commonly used tool to measure the thickness of graphene and few layer graphene (FLG) flakes on silicon oxide surfaces. ItExpand
Tailoring the atomic structure of graphene nanoribbons by scanning tunnelling microscope lithography.
The practical realization of nanoscale electronics faces two major challenges: the precise engineering of the building blocks and their assembly into functional circuits. In spite of the exceptionalExpand
Photonic nanoarchitectures in butterflies and beetles: valuable sources for bioinspiration
Nature began developing photonic nanoarchitectures millions of years before humanking. Often, in the living world, color is a communication chanel that may influence the chance of the individualExpand
Switchable reflector in the Panamanian tortoise beetle Charidotella egregia (Chrysomelidae: Cassidinae).
The tortoise beetle Charidotella egregia is able to modify the structural color of its cuticle reversibly, when disturbed by stressful external events. After field observations, measurements of theExpand
Gleaming and dull surface textures from photonic-crystal-type nanostructures in the butterfly Cyanophrys remus.
Photonic-crystal-type nanostructures occurring in the scales of the butterfly Cyanophrys remus were investigated by optical and electron microscopy (scanning and transmission electron microscopy),Expand
Large scale production of short functionalized carbon nanotubes
A simple mechano-chemical modification of multiwall carbon nanotubes is described. The use of ball-milling in specific atmosphere allows us to introduce functional groups like thiol, amine, amide,Expand
Living photonic crystals: Butterfly scales — Nanostructure and optical properties
Abstract The photonic crystal type nanostructures in the scales of male individuals of two butterfly species: Cyanophrys remus and Albulina metallica were investigated by electron microscopy andExpand
Carbon Filaments and Nanotubes : Common Origins, Differing Applications?
Preface. Photograph of the participants. Organizing and scientific committee and editors. List of contributors. Introduction. Part I: Introduction to carbon fibers and carbon nanotubes. Vapor-grownExpand
Continuous carbon nanotube production in underwater AC electric arc
Abstract A simple, low cost and continuous growth method for the production of well graphitized multi-wall carbon nanotubes is described. The growth takes place in an AC arc in water between twoExpand
Development of CNT/Si3N4 composites with improved mechanical and electrical properties
Silicon nitride based composites with different amount (1, 3 or 5 wt%) of carbon nanotubes have been prepared by using hot isostatic pressing. Composites with 1, 5 or 10 wt% carbon black and graphiteExpand
