Chromium-diffusion-induced degradation in metal-supported solid oxide fuel cells with porous stainless-steel supports

Yohei Miura, Satoshi Takemiya, Yuuki Shibata, Yuki Cho et autres

The degradation mechanisms in metal-supported solid oxide fuel cells (MS-SOFCs) are investigated through long-term durability testing and oxidation analysis of porous stainless steel under a humidified hydrogen atmosphere. An MS-SOFC fabricated using 1C44Mo29 steel undergoes a durability test for 8400 h, resulting …

Degradation Mechanisms of Metal-Supported SOFCs with Porous Stainless Steel Substrates

Yohei Miura, Satoshi Takemiya, Yuki Shibata, Yuki Cho et autres

Introduction Solid-oxide fuel cells (SOFCs) have attracted significant attention as an effective means for converting fuel into electricity. Recently, metal-supported SOFCs (MS-SOFCs) have been developed [1-3]. In comparison to ceramic-supported cells, MS-SOFCs demonstrate improved mechanical strength, which renders them well-suited for dynamic …

Fontan-associated liver disease: the importance of multidisciplinary teamwork in its management

Tomoya Tsuchihashi, Yuki Cho, Daisuke Tokuhara

The Fontan operation, which directly connects the superior and inferior vena cava to the pulmonary artery, is a palliative surgery for children with a functional or anatomic single ventricle. This procedure leads to hemodynamic changes (Fontan circulation) in patients, who tend to …

Neutron Non-destructive Inspection for Steel Welding & Resin Form Processing

Satoshi Koizumi, Shiho Tanaka, Yohei Noda, Tomoki Maeda et autres

In order to promote the industry use of neutrons from inside Ibaraki prefecture, we initiated a collaboration with the union of steel welding in Ibaraki. By using a combined method of neutrons, i.e., radiography (NR), diffraction (ND) and small-angle scattering (SANS), which …

Expert consensus on vaccination in patients with inflammatory bowel disease in Japan

Takashi Ishige, Toshiaki Shimizu, Kenji Watanabe, Katsuhiro Arai et autres

Immunosuppressive therapies can affect the immune response to or safety of vaccination in patients with inflammatory bowel disease (IBD). The appropriateness of vaccination should be assessed prior to the initiation of IBD treatment because patients with IBD frequently undergo continuous treatment with …

Platelet count and abdominal dynamic CT are useful in predicting and screening for gastroesophageal varices after Fontan surgery

Yoshiharu Isoura, Akira Yamamoto, Yuki Cho, Eiji Ehara et autres

OBJECTIVE: Patients who undergo Fontan surgery for complex cardiac anomalies are prone to developing liver and gastrointestinal complications. In particular, gastroesophageal varices (GEVs) can occur, but their prevalence is unknown. We aimed to elucidate the occurrence of GEVs and the predicting parameters …

Assessing liver stiffness with conventional cut‐off values overestimates liver fibrosis staging in patients who received the Fontan procedure

Yuki Cho, Daijiro Kabata, Eiji Ehara, Akira Yamamoto et autres

AIM: Patients who undergo the Fontan procedure for complex congenital heart disease are prone to liver cirrhosis. Liver stiffness (LS) reflects liver fibrosis stage in patients with chronic viral hepatitis; however, its accuracy in predicting liver fibrosis stage in Fontan patients is …
