Preparation of Morphology‑Tunable MSNs Supports and Their Catalytic Performance in Ethanol Dehydrogenation

Xiance Zheng, Tian Wen, Taolin, Wang Kai et autres

Mesoporous silica nanoparticles (MSNs) are classic ordered mesoporous materials with large specific surface area, tunable mesopore diameter, regular pore structure and excellent chemical stability. In this work, MSNs were employed as catalyst supports. By precisely adjusting the type and concentration of structure-directing …

Walking Alone to the North: The Origin and Historical Expansion of the Polyploid Parthenogenetic Lineage in a Weevil

Shota Murakami, Po‐Wei Hsu, Takashi Sato, Isao Matoba et autres

Abstract Polyploid parthenogenetic organisms are distributed nonrandomly with respect to their diploid sexual relatives, and this pattern has been well documented in plants. Comparable cases are rare in animals, and their origin has been reconstructed in only a few taxa. Separating general …

Unexpected aortic proximity after endoscopic hand suturing for gastric tube: importance of preoperative anatomical assessment

Ai Hirohata, Mikio Kobayashi, Akimichi Hayashi, Yu Ebisawa et autres

Endoscopic submucosal dissection (ESD) in reconstructed gastric tubes is technically challenging with high adverse events (AEs), especially in patients receiving antithrombotic or steroid therapy [ 1 ] [ 2 ] [ 3 ]. Based on the reported efficacy of endoscopic hand suturing …

Expansion of Feasible LC-Filter Design Region in Three-Phase CVCF Inverters via Pulse-Voltage-Injected Two-Phase Modulation

Taketo Ikeuchi, Shin-ichi Motegi

This paper quantitatively evaluates a pulse-voltage-injected two-phase modulation scheme incorporating a third-harmonic zero-sequence voltage (P2T-PWM) for constant-voltage constant-frequency (CVCF) inverters and clarifies its impact on LC filter design under carrier-frequency conditions selected to match the experimentally measured conversion efficiencies. The proposed scheme …
