Scanning probe recognition microscopy is a new scanning probe microscopy technique which enables selective scanning along individual nanofibers within a tissue scaffold. Statistically significant data for multiple properties can be collected by repetitively fine-scanning an identical region of interest. The results of a scanning probe recognition microscopy investigation of the surface roughnes...

This work presents the morphological characterization of CeO2 nanocrystals by the analysis of single unfiltered high-angle annular dark-field (HAADF)-high-resolution scanning transmission electron microscopy (HRSTEM) images. The thickness of each individual atomic column is estimated by the classification of its HAADF integrated intensity using a Gaussian mixture model. The resulting thickness ...

Scanning transmission electron microscopy (STEM) data with atomic resolution can contain a large amount of information about the structure of a crystalline material. Often, this information is hard to extract, due to the large number of atomic columns and large differences in intensity from sublattices consisting of different elements. In this work, we present a free and open source software to...

Phased array antennas afford many advantages over traditional reflector antennas due to their conformality, high aperture efficiency, and unfettered beam steering capability at the price of increased cost and complexity. This paper eliminates the complex and costly array backend via the implementation of a series fed array employing a propagation constant reconfigurable transmission line connec...

zeolite fau type-y is one of the most studied framework of all zeolites, and has been used as catalysts for number of reactions in the refinery and petrochemical industry. in this research, nanocrystalline zeolite y was synthesized by hydrothermal method. the crystal size of zeolite y is influenced by temperature, aging time, alkalinity, and water content. the synthesized zeolite nay is identif...

In the present work, we report a suitable approach for the preparation of BaTiO3 nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffra...

Superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °C without any subsequent calcination. The composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM)...

Sulfoanted poly(ether ether ketone) membranes were prepared by the sulfonating agent sulfuric acid. These membranes were modifed by incorporating conducting polymer polypyrrole in order to increase the ionic conductivity and reduce the methanol transmission rate. The modifed composite membranes were then compared on the basis of ionic conductivity, methanol transmission...
