Witryna1 wrz 2024 · Before moving to the impurity tolerance, we first explore the main origins of the impurities in the Fe-based alloys. Since the C, Si, and Cu are easy to be purified and their industrial raw materials are of high purity, the focus should be on the major constituents of Fe, P and B. Witryna27 mar 2024 · An automated chemical reactionimpurity prediction workflow is proposed, based on data mining chemical reaction databases (Reaxys®). The workflow aims to be data-centric, transparent, and interpretable. It was applied to three case studies: paracetamol, agomelatine, and lersivirine synthesis.

WitrynaSi was identified by TEM and XPS as a significant impurity, forming a blocking layer on the electrode surface. Full recovery of oxygen exchange kinetics on the measured samples was achieved after deposition of a La oxide film. Subsequent TEM studies indicate the formation of a porous La- and Si-containing film. Witryna13 kwi 2024 · In this study, the tendency of having different grain structures depending on the impurity levels in AZ91 alloys was investigated. Two types of AZ91 alloys were analyzed: commercial-purity AZ91 and high-purity AZ91. The average grain size of the commercial-purity AZ91 alloy and high-purity AZ91 is 320 µm and 90 µm, … Witryna11 kwi 2024 · Potassium deficiency confines root growth and decreases root-to-shoot ratio, thereby limiting root K+ acquisition. This study aimed to identify the regulation network of microRNA319 involved in low-K+ stress tolerance in tomato (Solanum lycopersicum).
