Correlation coefficient maps are constructed by computing the differences between neighboring diffraction patterns collected in a transmission electron microscope in scanning mode. The maps are shown to highlight material structural features like grain boundaries, second phase particles or dislocations. The inclination of the inner crystal interfaces are directly deduced from the resulting contrast.

Purpose: This study aimed to elaborate the mechanism of cuproptosis induced by HO in ulcerative colitis (UC).
Methods: Bioinformatics based on GSE107499, GSE87466, and GSE92415 datasets was performed to screen hub genes related to cuproptosis. In vitro, cell counting kit 8 (CCK8), flow cytometry were applied for detecting cell proliferation and apoptosis.

The activation of methane and other gaseous hydrocarbons at low temperature remains a substantial challenge for the chemistry community. Here, we report an anaerobic photosystem based on crystalline borocarbonitride (BCN) supported Fe-O nanoclusters, which can selectively functionalize C-H bonds of methane, ethane, and higher alkanes to value-added organic chemicals at 12 °C. Scanning transmission electron microscopy and X-ray absorption spectroscopy corroborated the ultrafine FeOOH and FeO species in Fe-O clusters, which enhanced the interfacial charge transfer/separation of BCN as well as the chemisorption of methane.

Two-dimensional (2D) materials offer a valuable platform for manipulating and studying chemical reactions at the atomic level, owing to the ease of controlling their microscopic structure at the nanometer scale. While extensive research has been conducted on the structure-dependent chemical activity of 2D materials, the influence of structural transformation during the reaction has remained largely unexplored. In this work, we report the layer-dependent chemical reactivity of MoS during a nitridation atomic substitution reaction and attribute it to the rearrangement of Mo atoms.

The study of the self-assembly of surfactants in aqueous solutions, though a traditional field, remains fascinating and full of novelty. In this article, the anionic perfluorodecanoic acid surfactant (PFA) is separately complexed with three hydroxyalkylamines (monoethanolamine (MEA), diethylamine (DEA), and triethanolamine (TEA)) in aqueous solutions. The transformation of aggregate morphologies from spherical unilamellar to nanotubes and then to spherical bilamellar is observed at room temperature, which is confirmed by cryo-transmission electron microscopy (cryo-TEM).

Energy production from renewable resources remains a leading focus in sustainable power generation. Recently, bifacial photovoltaic (BPV) systems have gained global attention for their enhanced energy yield. In this study, seashell waste was repurposed as an alternative reflector material for BPV modules.
