Microstructure-controlled Li ion conductive oxide–based ceramic solid electrolytes supporting high current densities

Nataly Carolina Rosero‐Navarro, Haruna Watanabe, Randy Jalem, Maycol F. Mena et autres

The fabrication of all-solid-state batteries using lithium metal that can be operated at high current densities (free lithium dendrites) is a recognized worldwide goal. We used a glassy lithium borate (LBO)–based microstructure as the grain boundary modifier of a garnet-type solid electrolyte …

Patient Preferences for Post‐Radical Cystectomy Treatment in Muscle‐Invasive Bladder Cancer: A Discrete Choice Experiment in Japan

Shugo Yajima, Shinro Hata, Naoya Masumori, Yoh Matsuoka et autres

OBJECTIVES: This study aimed to assess the treatment preferences of Japanese patients with muscle-invasive bladder cancer (MIBC) by quantifying their trade-offs between treatment attributes using a discrete choice experiment (DCE). METHODS: A DCE was conducted among MIBC patients post-radical cystectomy. Participants were …

Stress-Induced Martensitic Transformation in Na3YCl6

AKIRA B. MIURA, Koki Muraoka, Kotaro Maki, Saori Imada Kawaguchi et autres

Martensitic transformation with volume expansion plays a crucial role in enhancing the mechanical properties of steel and partially stabilized zirconia. We believe that a similar concept could be applied to unexplored nonoxide materials. Herein, we report the stress-induced martensitic transformation of monoclinic …

Multicoated and Folded Graph Neural Networks with Strong Lottery Tickets

Jiale Yan, Hiroaki Ito, Ángel López García-Arias, Yasuyuki Okoshi et autres

The Strong Lottery Ticket Hypothesis (SLTH) demonstrates the existence of high-performing subnetworks within a randomly initialized model, discoverable through pruning a convolutional neural network (CNN) without any weight training. A recent study, called Untrained GNNs Tickets (UGT), expanded SLTH from CNNs to …

Estimation of Grüneisen Parameter of Layered Superconductor LaO0.5F0.5BiS2−xSex (\(x = 0.2,0.4,0.6,0.8,1.0\))

Fysol Ibna Abbas, Kazuhisa Hoshi, Yuki Nakahira, Miku Yoshida et autres

The superconducting properties and structural parameters, including the Grüneisen parameter (γG), of the BiCh2-based (Ch: S, Se) layered superconductor LaO0.5F0.5BiS2−xSex were investigated. The superconducting transition temperature (Tc) increased with increasing Se concentration (x), and bulk superconductivity was induced by Se substitution. γG …

LC–MS peak assignment based on unanimous selection by six machine learning algorithms

Hiroaki Ito, Takashi Matsui, Ryo Konno, Makoto Itakura et autres

Recent mass spectrometry (MS)-based techniques enable deep proteome coverage with relative quantitative analysis, resulting in increased identification of very weak signals accompanied by increased data size of liquid chromatography (LC)-MS/MS spectra. However, the identification of weak signals using an assignment strategy with …

Bipolar doping and thermoelectric properties of Zintl arsenide Eu5In2As6

Naoki Tomitaka, Yosuke Goto, Kota Morino, Kazuhisa Hoshi et autres

Zintl compounds exhibit promising thermoelectric properties because of the feasibility of the chemical tuning of their electrical and thermal transport. While most Zintl pnictides are known to show p-type polarity, recent developments in high-performance n-type Mg3Sb2-based thermoelectric materials have encouraged further identification …

Kinetically Stabilized Cation Arrangement in Li 3 YCl 6 Superionic Conductor during Solid‐State Reaction

Hiroaki Ito, Kazuki Shitara, Yongming Wang, Kotaro Fujii et autres

Abstract The main approach for exploring metastable materials is via trial‐and‐error synthesis, and there is limited understanding of how metastable materials are kinetically stabilized. In this study, a metastable phase superionic conductor, β ‐Li 3 YCl 6 , is discovered through in …
