Manufacturing of orifices in glass like materials, e.g. Nanocapillaries, and objects obtained according to this process
Aleksandra Radenovic, Lorenz Jan Steinbock
The ability to reshape nanopores and observe their shrinkage under an electron microscope is a powerful and novel technique14,17. It increases the sensitivity of the resistive pulse sensing and enables to detect very short and small molecules12,31. However ...
2016Statistical nanoscale study of localised radiative transitions in GaN/AlGaN quantum wells and AlGaN epitaxial layers
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Etienne François Olivier Giraud
Compositional disorder has important consequences on the optical properties of III-nitride ternary alloys. In AlGaN epilayers and AlGaN-based quantum heterostructures, the potential fluctuations induced by such disorder lead to the localisation of carriers ...
Iop Publishing Ltd2016Polarity of translation boundaries in antiferroelectric PbZrO3
The polarity of translation boundaries (TBs) in antiferroelectric PbZrO3 is investigated. We show that previous experimentally reported polar property of RIII-1 type TB can be well approximated by a strain-free rigid model. Based on this, the modeling inve ...
Pergamon-Elsevier Science Ltd2015Core-shell InGaN/GaN nanowire light emitting diodes analyzed by electron beam induced current microscopy and cathodoluminescence mapping
Hua Zhang, Gwénolé Jean Jacopin
We report on the electron beam induced current (EBIC) microscopy and cathodoluminescence (CL) characterization correlated with compositional analysis of light emitting diodes based on core/shell InGaN/GaN nanowire arrays. The EBIC mapping of cleaved fully ...
Royal Soc Chemistry2015Electrically conductive self-healing polymer composite coatings
Véronique Michaud, Yves Leterrier, Brennan Margaret Bailey
The goal of the research described herein is the fabrication and assessment of electrically conductive partially-cured epoxy coatings which, upon cracking, autonomously restore barrier, mechanical and electrical properties via a microcapsule based healing ...
2015Oxidation mechanism of nickel particles studied in an environmental transmission electron microscope
Jan Van Herle, Cécile Hébert, Aïcha Hessler-Wyser, Quentin Thomas Jeangros
The oxidation of nickel particles was studied in situ in an environmental transmission electron microscope in 3.2 mbar of O-2 between ambient temperature and 600 degrees C. Several different transmission electron microscopy imaging techniques, electron dif ...
Pergamon-Elsevier Science Ltd2014Semiautomated correlative 3D electron microscopy of in vivo-imaged axons and dendrites
Marco Cantoni, Graham Knott, Bohumil Maco
This protocol describes how in vivo-imaged dendrites and axons in adult mouse brains can subsequently be prepared and imaged with focused ion beam scanning electron microscopy (FIBSESEM). The procedure starts after in vivo imaging with chemical fixation, f ...
Nature Publishing Group2014Correlative in vivo 2 photon and focused ion beam scanning electron microscopy of cortical neurons
Marco Cantoni, Graham Knott, Bohumil Maco
Correlating in vivo imaging of neurons and their synaptic connections with electron microscopy combines dynamic and ultrastructural information. Here we describe a semi-automated technique whereby volumes of brain tissue containing axons and dendrites, pre ...
Public Library of Science2013Universal sample holder
This device is for holding samples during their preparation prior to imaging in the electron microscope. The design means it can be transferred between the light and electron microscopes as well as trimming devices used to prepare the final sample. It can ...
