Trapping of Thermal Neutrons, (II)

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1962
Concerning thermal neutron trap reactors, a comparative study of trapping media is made by an analytical approach especially to derive criteria of highly trapping media. Spherical and cylindrical shapes of media are analyzed in the two-group diffusion theory.

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

Advanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Neutron Thermalization in Graphite

Journal of Nuclear Science and Technology, 1973
The neutron thermalization and diffusion parameters in graphite were determined by pulsed technique for the neutron flux and the neutron density spectra, respectively. Measurements were performed on assemblies of geometrical bucklings between 2.26×10−3/cm2 and 15.58 × 10−3/cm2, in which, by suitable arrangement of the neutron source and detector, the ...

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...

Large‐Scale Growth of Self‐Poled Ferroelectric Rashba Semiconductor α‐GeTe(111) Thin Films: A Crucial Step Towards Future CMOS‐Compatible Ferroelectric Spintronic Devices

Advanced Science, EarlyView.
Ferroelectric Rashba semiconductors promise ultralow‐power devices but lack industry‐quality films. This work demonstrates CMOS‐compatible fabrication of high‐quality α‐GeTe(111) films via magnetron sputtering, enabled by a 5 nm Sb2Te3 seed layer. Structural and ferroelectric analyses show robust, switchable polarization comparable to MBE films, paving
