Structure of Ion Pair Receptor Combined with LiCl in Concentrated Acetonitrile Solutions Studied by Neutron Diffraction with Li/Li Isotopic Substitution Method.

Neutron diffraction measurements with the Li/Li isotopic substitution method have been carried out to obtain direct structural information on the ion pair receptor, CHON, combined with LiCl ion pair in concentrated acetonitrile solutions. The difference interference term, Δ(), was derived from the difference between the total interference term observed for Li- and Li-enriched sample solutions. Structural parameters concerning the LiCl-receptor complex were determined by the least-squares fitting analysis of the observed Δ().

Successful factors for improving aortic remodeling with thoracic endovascular repair and bare stent extension.

Objective: Proximal ExTension to Induce COmplete ATtachment (PETTICOAT), which uses downstream bare metal stents for structural support, demonstrates potential, yet its adoption is limited by variable outcomes. This study elucidates the potential of PETTICOAT in aortic dissection, emphasizing the determinants that guide patient selection.

Methods: A retrospective analysis of 60 patients who underwent full PETTICOAT for aortic dissections was conducted.

Visualizing the invisible: aortopulmonary window diagnosis enhanced by 3D computer graphics.

An aortopulmonary window is a rare disorder that occurs in 0.1–0.2% of all congenital disorders.

Enabling quantitative comparison of wastewater surveillance data across methods through data standardization without method standardization.

Wastewater surveillance for COVID-19 and other pathogens has expanded globally. Rapid development and availability of various assays has facilitated swift adoption of wastewater surveillance in localities with diverse requirements. However, it presents challenges in comparing data due to methodological variations.

Specific line shape of the lowest frequency Raman scattering modes of triethylene glycol.

For both dielectric spectroscopy and light scattering spectra, the relaxation modes in the microwave region have been characterized by the Debye relaxation model, which is determined by the peak frequency, or by an empirically extended model (e.g., Cole-Davidson and Kohlrausch-Williams-Watts), which has the appropriate line shape.
