Investigations on the Origin of Topotactic Phase Transition of LaCoO Thin Films with In Situ XRD and Ambient Pressure Hard X-ray Photoelectron Spectroscopy.

With the applications of in situ X-ray diffraction (XRD), electrical - measurement, and ambient pressure hard X-ray photoelectron spectroscopy (AP-HAXPES), the characteristics of the topotactic phase transition of LaCoO (LCO) thin films are examined. XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.

Unraveling the Genetic Landscape of Langerhans Cell Histiocytosis in Korean Patients: Comprehensive Insights from Mutational Profiles and Clinical Correlations.

Purpose: This study aimed to conduct a comprehensive genetic analysis of patients with Langerhans cell histiocytosis (LCH), focusing on the frequency of MAPK pathway mutations, detailed mutation profiles of MAPK pathway genes, and their correlation with clinical features and prognosis in Korean LCH patients.

Materials And Methods: We performed targeted next-generation sequencing, capable of capturing exons from 382 cancer-related genes, on genomic DNA extracted from formaldehyde-fixed and paraffin-embedded samples of 45 pathologically confirmed LCH patients.

Results: The majority of patients (91.

Chronic intractable nontuberculous mycobacterial-infected wound after acupuncture therapy in the elbow joint: A case report.

Background: Musculoskeletal (NTM) infections are rare, particularly post-acupuncture therapy, and present diagnostic challenges due to their infrequency and potential severity. Prompt recognition and appropriate management are crucial for optimal outcomes. NTM-infected wounds involving the joints are difficult to treat, and only a few cases have been reported.

Toward Long-Life High-Voltage Aqueous Li-Ion Batteries: from Solvation Chemistry to Solid-Electrolyte-Interphase Layer Optimization Against Electron Tunneling Effect.

Water is pursued as an electrolyte solvent for its non-flammable nature compared to traditional organic solvents, yet its narrow electrochemical stability window (ESW) limits its performance. Solvation chemistry design is widely adopted as the key to suppress the reactivity of water, thereby expanding the ESW. In this study, an acetamide-based ternary eutectic electrolyte achieved an ESW ranging from 1.
