Low-flux neutron imaging [PDF]

, 1973
Judicious use of scintillation screens greatly improves the capabilities for low-flux neutron imaging. Room temperature, cooled /sup 6/LiF-- ZnS(Ag) and gadolinium oxysulfide (Gd/sub 2/O/sub 2/S: Tb) were evaluated for direct exposures, and x-ray intensifying screens were evaluated with dysprosium and europium transfer screens.

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Characterization of neutron flux spectra for radiation effects studies [PDF]

, 2013
textThe effects of neutron displacement damage on materials are sensitive to neutron energy spectra. In controlled neutron damage experiments, a well characterized neutron flux spectrum is critical in determining the equivalent dose for displacement ...

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Basis for the computation of the energy dependence of the neutron flux and slowing down density in a bare reactor.

, 1963
A method is described for the computation of the energy dependence of the neutron flux and slowing down density in a bare reactor to form the basis of a 7090 Fortran computer program for survey studies of power reactors.

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 ...

Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut

Advanced Science, EarlyView.
We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...
