    Ultra-low reverse leakage NiOx/β-Ga2O3 heterojunction diode achieving breakdown voltage >3 kV with plasma etch field-termination by Yizheng Liu, Saurav Roy, Carl Peterson, Arkka Bhattacharyya, Sriram Krishnamoorthy

    Published 2025-01-01
    “…This work reports the fabrication and characterization of a NiOx/β-Ga2O3 heterojunction diode (HJD) that uses a metallic nickel (Ni) target to deposit NiOx layers via reactive RF magnetron sputtering and lift-off processing with >3 kV breakdown voltage, ultra-low reverse current leakage under high reverse bias, and a high junction electric field (>3.34 MV/cm). …”

    Identification of Adamkiewicz artery by 4D flow MRI and intra-arterial ultra-high-resolution CT angiography in preoperative assessment of patients with chronic aortic dissection: A case report by Satoshi Higuchi, MD, PhD, Yuta Sato, MD, Hideki Ota, MD, PhD, Ryuichi Mori, RT, Yuki Ichinoseki, RT, Hitoshi Nemoto, RT, Shingo Kayano, RT, Kiichiro Kumagai, MD, PhD, Yoshikatsu Saiki, MD, PhD, Kei Takase, MD, PhD

    Published 2025-03-01
    “…In a 45-year-old man with chronic aortic dissection requiring thoracoabdominal aortic repair, conventional contrast-enhanced CT or MR angiography failed to detect AKA due to the large entry tear and an enlarged false lumen. Intra-arterial ultra-high-resolution CT angiography combined with hemodynamic assessment using 4D flow MRI successfully identified the AKA, allowing for aortic repair with targeted intercostal artery reconstruction without postoperative signs of spinal cord ischemia.…”
