Investigating lattice strain in Au nanodecahedrons
The three dimensional (3D) structural characterization of nanoparticles is crucial in materials science since many properties heavily depend on size, surface to volume ratio and…The 16th European Microscopy Congress 2016
Operando electron microscopy in heterogeneous catalysis
Visualizing nanoparticles at atomic-resolution by transmission electron microscopy (TEM) is beneficial for the understanding of their physico-chemical properties. However, nanoparticles respond dynamically to changes in…The 16th European Microscopy Congress 2016
Status of the SALVE-microscope: Cc-correction for atomic-resolution TEM imaging at 20kV
With the goal to enable atomic resolution TEM observations on beam sensitive materials the SALVE project had been initiated to develop a dedicated low-voltage TEM…The 16th European Microscopy Congress 2016
Electron microscopy investigations of cation exchange in colloidal PbSe/CdSe nanocrystals
Cation exchange is a very powerful method for creating heterogeneous nanocrystals (NCs), such as core-shell or rod-tip nanostructures. Here we present an overview of the…The 16th European Microscopy Congress 2016
HAADF-STEM observation of twinned structure formed in gold nanorods by near-infrared pulsed laser irradiation
Gold nanorods have been drawing much interests widely in various science and engineering fields because of their characteristic optical properties [1]. Due to…The 16th European Microscopy Congress 2016

Mechanisms of polarity inversion during the MOVPE growth of III-nitrides on sapphire investigated by high resolution transmission electron microscopy.
The most important compound semiconductors for applications in optoelectronics crystallize in the sphalerite or wurtzite structure, which contain polar axes. Though the polarity is of…The 16th European Microscopy Congress 2016
Quantifying the hole distribution in cuprates: Atomic-resolution near-edge fine-structures of the superconductor Sr3Ca11Cu24O41
Sr14-xCaxCu24O41 is a fascinating member in the family of cuprates, not only because of its peculiar crystal structure where two distinct units, corner-shared CuO2 chains…The 16th European Microscopy Congress 2016
Novel spectroscopy with atomic-size aberrated electron probes in stem
it has been theoretically argued that atomic-size electron probes with customized phase distributions can detect electron magnetic circular dichroism (EMCD) [1]. Based on this prediction…The 16th European Microscopy Congress 2016
Mn 4+ holes localization around divalent cations in low-hole doped manganites
Magnetotransport properties of low Ca doping La1-xCaxMnO3 perovskite related manganites have been described on the basis of the existence of isolated metallic (M)-double exchange (DE)…
