Mapping functional groups on oxidised multi-walled carbon nanotubes at the nanometre scale.
Despite voluminous research on the acid oxidation of carbon nanotubes (CNTs), there is a distinct lack of experimental results showing distributions of functional groups at the nanometre length scale. Here, functional peaks have been mapped across individual multi-walled CNTs with low-dose, monochromated electron energy-loss spectroscopy (EELS) in the scanning transmission electron microscope (...
متن کاملElectron Energy-Loss Spectroscopy: Measuring Optical Properties at the Nanometre Scale
Electron energy-loss spectroscopy (EELS) is widely used to study the composition and electronic structure of materials at the nanometre scale. The low-loss region of the EEL spectrum (< ~50 eV) is of particular interest for the study of optical properties. Examples of the applications of EELS to measure the optical properties, and, in particular, of individual nanoparticles will be presented. C...
متن کاملFULL CRITICAL REVIEW In situ single asperity wear at the nanometre scale
The interface of two contacting materials experiences complex physical and possibly chemical reactions when one slides with respect to another. While tribology, a subject studying sliding contact, has been comprehensively elucidated for a variety of materials ranging from metals, carbides, inorganic materials and polymers, direct imaging data of the processes taken place at the nanometre or ato...
متن کاملResistance switching at the nanometre scale in amorphous carbon
The electrical transport and resistance switching mechanism in amorphous carbon (a-C) is investigated at the nanoscale. The electrical conduction in a-C thin films is shown to be captured well by a Poole–Frenkel transport model that involves nonisolated traps. Moreover, at high electric fields a field-induced threshold switching phenomenon is observed. The following resistance change is attribu...
متن کاملNanometre-scale probing of spin waves using single-electron spins
Pushing the frontiers of condensed-matter magnetism requires the development of tools that provide real-space, few-nanometre-scale probing of correlated-electron magnetic excitations under ambient conditions. Here we present a practical approach to meet this challenge, using magnetometry based on single nitrogen-vacancy centres in diamond. We focus on spin-wave excitations in a ferromagnetic mi...
