Here we report the application of energy-filtered electron radial distribution function (eRDF) analysis, combined with transmission electron microscopy imaging and X-ray powder diffraction, for elucidating the crystal structure and describing local order in carbon nitride powders with different degrees of crystallinity: (1) sodium polyheptazine imide (Na-PHI) and (2) amorphous CN covalent...

Ultrasmall metallic nanoparticles (diameter 1 to 2 nm) are of interest in research as they can be functionalized and used in biomedical applications. One of the most prominent methods for analyzing ultrasmall nanoparticles is high-resolution transmission electron microscopy (HRTEM). To effectively use HRTEM for a large-scale analysis of ultrasmall nanoparticles, an automated image processing...

Electron diffraction (3D ED), that is using both the continuous rotation method and software as we know from X-ray crystallography, is gaining a lot of attention in all fields of research from organic and inorganic molecules, over geological sciences, material sciences to energy-storage materials and many others.

Here we showcase results from case studies dealing with challenging organic...

A common approach to deal with the unknown surface emissivity is to measure the thermal emission at multiple wavelengths – an approach called multi-wavelength pyrometry. Our new pyrometer uses 8 wavelengths from 600 to 1500 nm and different types of detectors, such as photodiodes and Multi Pixel Photon Counters (MPPC). This allows one to measure the temperature in a broad temperature range up...
