Nanoarchitectures based on graphene and carbon nanotubes: design, synthesis and properties on Earth is made up of atoms, the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies. The concepts that seeded nanotechnology were first discussed in by renowned physicist Richard Feynman in his talk There's Plenty of Room at the Bottom, in which he described the possibility of synthesis via direct manipulation of atoms. However, experimental nanotechnology did not come into its own until , when International Business Machines IBM scientists in Zurich, Switzerland, built the first scanning tunneling microscope STM. STM allows us to see single atoms by scanning a tiny probe over the surface of a silicon crystal. Other significant advances were made in , when chemists discovered how to create a soccer-ball-shaped molecule of 60 carbon atoms, which they called buckminsterfullerene also known as C 60 or buckyballs.
This introduction to graphene has been created to impart a general understanding of what graphene is, the types of graphene available, as well as synthesis methods and applications of graphene. Graphene is an allotrope of carbon that exists as a two-dimensional planar sheet. One way to think of graphene is as a single atomic graphite layer. Graphene is technically a non-metal but is often referred to as a quasi-metal due to its properties being like that of a semi-conducting metal. Each carbon atom is covalently bonded sp 2 hybridized to three other carbon atoms in a hexagonal array, leaving one free electron per each carbon atom. This free electron exists in a p-orbital that sits above the plane of the material. Each hexagon in the graphene sheet exhibits two pi-electrons, which are delocalized, allowing for an efficient conduction of electricity.

Carbon Nanotubes History And Production Methods
Carbon nanotubes — what they are, how they are made, what they are used for What are carbon nanotubes? Carbon nanotubes CNTs are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms graphene. They can be single-walled SWCNT with a diameter of less than 1 nanometer nm or multi-walled MWCNT , consisting of several concentrically interlinked nanotubes, with diameters reaching more than nm. Their length can reach several micrometers or even millimeters.
Carbon nanotubes CNTs are tubes made of carbon with diameters typically measured in nanometers. Carbon nanotubes often refer to single-wall carbon nanotubes SWCNTs with diameters in the range of a nanometer. They were discovered independently in by Iijima and Ichihashi  and Bethune et al. Single-wall carbon nanotubes are one of the allotropes of carbon , intermediate between fullerene cages and flat graphene.
Functionalizing Graphene and Carbon Nanotubes
It seems that you're in Germany. We have a dedicated site for Germany. Authors: Ferreira , F. This book compiles all current information on the different types of functionalization of carbon nanotubes CNTs and graphene, both covalent and non-covalent. The book starts with a general overview of the synthesis, characterization and application of functionalized CNTs and graphene. Special attention is dedicated to the characterization of functionalized materials, a topic rarely addressed on the literature.
This dissertation investigates the application of graphene and carbon nanotubes CNTs for thermal management of high-power batteries and interconnects. The research is focused on three applications: i thermal phase change materials PCMs with graphene fillers for thermal management of battery packs; ii CNTs incorporated in the battery electrodes; iii graphene coatings for copper Cu interconnects. In this study, lithium-ion Li-ion batteries were used for testing the proposed approaches. The graphene solutions for synthesis of graphene PCMs were obtained by the liquid-phase exfoliation. The graphene coatings on Cu films were grown by the chemical vapor deposition CVD. In the first part of the dissertation, it is demonstrated that thermal management of Li-ion batteries can be drastically improved using PCM with graphene fillers. Incorporation of graphene to the hydrocarbon-based PCM allowed one to increase its thermal conductivity by more than two orders of magnitude while preserving its latent heat storage ability.

Семь ступеней. Он мысленно прорепетировал предстоящее убийство. Если у входа на площадку взять вправо, можно увидеть самый дальний левый угол площадки, даже еще не выйдя на. Если Беккер окажется там, Халохот сразу же выстрелит. Если нет, он войдет и будет двигаться на восток, держа в поле зрения правый угол, единственное место, где мог находиться Беккер. Он улыбнулся.
