Kengo Shimanoe教授の研究室では、酸化物半導体を用いた高感度ガスセンサーや酸素透過膜の開発を主軸としています。特に、酸化インジウムと酸化銅の複合酸化物ナノスフィアを用いた一氧化炭素（CO）センサーの特性向上や、バrium・ランタン・鉄酸化物を基にした非対称酸素透過膜の高効率化に取り組んでいます。これらの研究は、環境モニタリングやエネルギー変換デバイスの実用化に貢献するものです。

High oxygen permeability was achieved using an asymmetric Ba0.95La0.05FeO3−δ membrane. In this membrane, oxygen diffuses physically through pores of a porous support and oxygen permeates electrochemically through a dense layer. The oxygen permeation flux of the asymmetric Ba0.95La0.05FeO3−δ membrane reached more than 10 cm3 (STP) min−1 cm−2 from a test gas containing 50% oxygen at 930 °C. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents
Clustered indium oxide/copper oxide (In<sub>2</sub>O<sub>3</sub>/CuO) nanospheres with different CuO amounts were successfully synthesized as sensing materials for the carbon monoxide (CO) detection. Component and morphological characterizations were performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Sensing performance for CO of the clustered In<sub>2</sub>O<sub>3</sub> and In<sub>2</sub>O
