Establishment of a general one-pot cascade reaction protocol would dramatically reduce the effort multistep organic synthesis. We demonstrate that unique structure M12L24 self-assembled complexes gives them potential to serve as catalyst carriers for enabling continuous chemical transformations. A stereoselective (allylic oxidation followed by Diels–Alder cyclization) with two intrinsically incompatible catalysts was demonstrated. Our system is advantageous in terms availability,...
Abstract The main approach for exploring metastable materials is via trial‐and‐error synthesis, and there limited understanding of how are kinetically stabilized. In this study, a phase superionic conductor, β ‐Li 3 YCl 6 , discovered through in situ X‐ray diffraction after heating mixture LiCl powders. While Cl − arrangement represented as hexagonal close packed structure both synthesized below 600 K stable α above K, the Li + Y 3+ determined by neutron brought about cell with 1/√3 ‐axis...
This study aimed to assess the treatment preferences of Japanese patients with muscle-invasive bladder cancer (MIBC) by quantifying their trade-offs between attributes using a discrete choice experiment (DCE). A DCE was conducted among MIBC post-radical cystectomy. Participants were presented hypothetical options differing in such as efficacy Disease-free survival (DFS), side effects, administration, and cost. Preference data analyzed determine each attribute's relative importance (RI),...
Abstract The rate-determining step of a C6-C3 dimeric non-phenolic β-O-4 type lignin model compound, 2-(2-methoxyphenoxy)-1-(3,4-dimethoxyphenyl)propane-1,3-diol (veratrylglycerol-β-guaiacyl ether, VG), was evaluated under acidolysis conditions (0.2 mol/l HBr in 82% aqueous 1,4-dioxane at 85°C) by comparing the disappearances between VG and corresponding compound labeled β-position VG, 2-(2-methoxyphenoxy)-1-(3,4-dimethoxyphenyl)(2–2H)propane-1,3-diol. disappearance occurred more rapidly...
Abstract A homoleptic zinc(II) helicate organized by a pair of achiral dipyrromethene ligands through coordination was synthesized to evaluate the chiroptical properties. This zinc complex showed strong exciton‐coupled responses from helical configuration with large absorption dissymmetry factor | g abs (up 0.20). More importantly, intense polarized luminescence in far‐red region (700–850 nm) fluorescence quantum yield Φ FL 0.23 observed for this lum 0.022, largest value among rare‐earth‐...
A series of π-extended mono- and bis-BODIPY (BODIPY=boron-dipyrromethene) derivatives, namely, benzo[a]phenanthrene-fused BODIPY (Phena-Mono-BDP), benzo[a]anthracene-fused (Ant-Mono-BDP), dibenz[a,h]anthracene (DBA)-bridged (Ant-Bis-BDP), were designed synthesized to examine their structural, electrochemical, photophysical properties. Single-crystal X-ray crystallographic analyses demonstrated the planar configuration Ant-Mono-BDP, in contrast that nonplanar Phena-Mono-BDP, whereas...

A new family of pi-conjugated delocalized biradical compound is developed. The solution 1,4-bis(2,5-diphenylimidazol-4-ylidene)cyclohexa-2,5-diene shows the ESR signal consisting a moderately broad unresolved line, Delta H(pp) approximately 1 mT, at room temperature. presence thermal equilibrium between triplet state and singlet confirmed by measurements, spin concentration determined as 7.90 x 10(21) spin/mol 300 K. can also be controlled modifying molecular planarity. Moreover,...
Shotgun proteomics is a powerful method for comprehensively identifying and quantifying tryptic peptides, but it difficult to analyze proteolytic events. One-dimensional gel liquid chromatography-tandem mass spectrometry (GeLC-MS/MS) enables the separation of fragments using SDS-PAGE followed by identification LC-MS/MS. GeLC-MS/MS thus an excellent fragmentation. However, lower reproducibility extraction nano flow LC-MS/MS can produce inaccurate results in comparative analyses protein...
Zintl arsenide Eu 5 In 2 As 6 is demonstrated as a bipolar dopable thermoelectric material.
An extremely large displacement of the indium site in In-S6 octahedra LnOInS2 (Ln = La, Ce, and Pr) was found synchrotron X-ray diffraction. LaOInS2 with off-center exhibited a wider optical band gap than CeOInS2 PrOInS2 on-center indium. Therefore, electronic structure is governed by an displacement. All produced H2 gas under visible light irradiation presence sacrificial electron donors.
Abstract This study aimed to clarify the effect of different solvents, aqueous 1,4-dioxane, ethanol, or ethylene glycol at various mol%, on formation rate benzyl cation, which forms via two steps, protonation hydroxy alkoxy group as a pre-equilibrium step and subsequent liberation water corresponding alcohol molecule, respectively, in model system lignin acidolysis, focusing distinguishing effects both steps. For this aim, acidolysis reactions were conducted solutions organic solvents that...
Martensitic transformation with volume expansion plays a crucial role in enhancing the mechanical properties of steel and partially stabilized zirconia. We believe that similar concept could be applied to unexplored nonoxide materials. Herein, we report stress-induced martensitic monoclinic Na3YCl6 an ∼3.4% expansion. In situ synchrotron X-ray diffraction atomistic simulations showed anisotropic crystallographic from rhombohedral occurs exclusively under uniaxial pressure; no effect is...
Abstract Recent mass spectrometry (MS)-based techniques enable deep proteome coverage with relative quantitative analysis, resulting in increased identification of very weak signals accompanied by data size liquid chromatography (LC)–MS/MS spectra. However, the using an assignment strategy poorer performance results imperfect quantification misidentification peaks and ratio distortions. Manually annotating a large number within dataset is not realistic approach. In this study, therefore, we...
Abstract With the recent development of endoscopic instruments, laparoscopic surgery has come into widespread use. Compared to traditional open abdominal surgery, method offers a reduction physical burden on patient, in‐hospital period, and recovery period. On other hand, more technical training is required compared since conducted by observing two‐dimensional image obtained lapar‐oscopy. Many simulators for have been developed in various research institutions. Most these, however, require...

In the original Bayesian network model, hierarchical structure of variables is not assumed.When modeling relation between sales products in a retail industry, it better to consider items (e.g., first, second, and third classifications).To apply such data, we have focus on one hierarchy only order acquire model.However, focusing first or second classification provides high-level view, but makes difficult understand customers' purchasing behavior detail.On other hand, results considerable...
