Highly improved thermoelectric performance of Nb-doped SrTiO3 due to significant suppression of phonon thermal conduction by synergetic effects of pores and metallic nanoparticles

Autor: Kosuke Watanabe, Michitaka Ohtaki, Shinji Hirata

Publikováno v: Ceramics International. 46:25964-25969

A remarkable thermoelectric performance in oxide materials was achieved by Nb and Ni co-doped strontium titanate (STNNO) containing pores and Ni nanoparticles. A combined structure of macroporus matrix and the Ni nanoparticles was realized by an exso

Simultaneous Enhancement in the Electrical Conductivity and Reduction in the Lattice Thermal Conductivity Leading to Enhanced Thermoelectric ZT Realized by Incorporation of Metallic Nanoparticles into Oxide Matrix

Autor: Michitaka Ohtaki, Shinji Hirata

Publikováno v: Evergreen. 7(1):1-6

Nanoporous Fe_3O_4 composites containing metallic Cu nanoparticles were synthesized by reducing-leaching treatment of CuFe_2O_4 precursor. Thermoelectric properties of the composites sintered at 1270 ºC greatly improved compared with Fe_3O_4 without

Publikováno v: Stem Cells Translational Medicine

Donor-independent platelet concentrates for transfusion can be produced in vitro from induced pluripotent stem cells (iPSCs). However, culture at 37°C induces ectodomain shedding on platelets of glycoprotein Ibα (GPIbα), the von Willebrand factor

Enhanced Thermoelectric Performance of Porous SrTiO3 with Exsolved Ni Nanoparticles

Autor: Shinji Hirata, Michitaka Ohtaki, Koichiro Suekuni

Publikováno v: ECS Meeting Abstracts. :1974-1974

Nanocomposite structuring is one of the key directions to improve the thermoelectric performance of bulk materials by enabling a significant reduction of the thermal conductivity and a possible enhancement in the power factor at the same time. In thi

Publikováno v: Journal of Clinical Investigation. 123:3802-3814

Congenital amegakaryocytic thrombocytopenia (CAMT) is caused by the loss of thrombopoietin receptor-mediated (MPL-mediated) signaling, which causes severe pancytopenia leading to bone marrow failure with onset of thrombocytopenia and anemia prior to

Cancelable Biometrics with Provable Security and Its Application to Fingerprint Verification

Autor: Kenta Takahashi, Shinji Hirata

Publikováno v: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences. :233-244

Biometric authentication has attracted attention because of its high security and convenience. However, biometric feature such as fingerprint can not be revoked like passwords. Thus once the biometric data of a user stored in the system has been comp
