“…This capability is combined with a high degree of automation, eliminating much of the effort associated with manual processing of data. These factors have led to a number of successful applications (Klinger et al, 2016;Gartnerova et al, 2017;Steele et al, 2016;Polyakov et al, 2016;Butanovs et al, 2017;Singh et al, 2017;Zhao et al, 2016).…”

A new release of the CrysTBox software is introduced. The original toolbox allows for an automated analysis of transmission electron microscope (TEM) images and for crystallographic visualization. The existing tools, which are capable of highly precise analyses of high‐resolution TEM images, as well as spot, disc and ring diffraction patterns, are extended to include a tool for automatically measuring TEM sample thickness using convergent beam electron diffraction in a two‐beam approximation. An implementation of geometric phase analysis is newly available, employing one of the existing tools to identify parameters and indices of crystallographic planes depicted in the input image and allowing easier and more accurate analysis. The crystallographic visualization capabilities are extended as well. Along with the simulated diffraction pattern and atomic structure, a stereographic projection and inverse pole figure tool is newly offered. A new tool able to visualize the atomic structure of two different phases and their interface is also introduced.

“…3 Exogenous contrast agents (CAs) can shorten the T1 and T2 relaxation times of local protons and, thus, are often introduced to focus and increase image contrast. [7][8][9] Currently, Gd-based T1 and iron oxide nanoparticle (IONPs)-based T2 CAs are predominately employed, but their efficacies generally decline markedly at higher field. 10,11 Gd 3+ is well known for its T1 relaxation enhancing capability due to its isotropic 4f electron configuration and long electronic relaxation time ( ), but the r1 relaxivity of Gd-chelates T1 agents rapidly drops at higher fields (as much as one-third).…”

Summary Metal oxide nanostructures gain specific interest for bifunctional electrocatalytic functions in efficient water splitting reactions. From this perspective, Gd‐In‐Zn‐based ternary oxides were solution processed and studied for oxygen and hydrogen evolution activities under different pH alkaline media. The nanostructure morphology was ascertained using high‐power analytical tools such as scanning and transmission electron microscopes. Signals obtained from X‐ray diffraction data revealed the prevalence of Gd2O3 phase in ternary oxide. Valence state of Gd, In, and Zn ions and their oxide traits was examined using X‐ray photoelectron spectroscopy. Ternary oxides of Gd‐In‐Zn showcased their overall potential for water splitting applications. Overpotential (η) for oxygen and hydrogen (OER/HER) evolution reactions was recorded to be 282 and 271 mV for ±10 mA/cm2. The results demonstrated the processed oxide as an effective OER/HER electrocatalyst with profound Tafel slopes (121/64 mV/dec for OER/HER) and excellent long‐term stability.
