In-situ Loading Device for Neutron Texture Diffractometer
Yuanzineng kexue jishuThe texture of polycrystalline material is the preferred orientation distribution of its crystallites. As an intrinsic feature of metals, alloys, ceramics and polymers, texture strongly affects many properties of polycrystalline materials.

High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system [PDF]
, 2012 In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedicated to the classical piezoelectric, lead-zirconate-titanate (PZT) ceramic ...

Advanced Science, EarlyView.The Prussian Blue Analogue molecular magnet KMnFeHCF is demonstrated as a high‐performance cathode for ultra‐fast aqueous ammonium‐ion batteries. A full cell using KMnFeHCF and graphite delivers ~71 mAh g−1 at 1.25 A g−1 and ~51 mAh g−1 at 2.2 A g−1, retaining 50% capacity after 1850 cycles. Its scalability, cycling stability, and low cost offer strong

In Situ Shape and Distance Measurements in Neutron Scattering and Diffraction
, 1996 Neutron scattering combined with selective isotopic labeling and contrast matching is useful for obtaining in situ structural information about a selected particle, or particles, in a macromolecular complex. The observed intensities, however, may be distorted by inter-complex interference and by scattering-length-density fluctuations of the (otherwise)

In situ neutron diffraction study of Li insertion in Li4Ti5O12
Electrochemistry Communications, 2010 Developing an efficient in situ electrochemical cell for neutron diffraction of electrode materials for Li-ion batteries remains a major technical challenge. We recently published the results of the first experiment carried out with such a cell developed by our group. In order to improve the quality of data we optimized the preparation of the electrode,

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 ...

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy
Advanced Science, EarlyView.By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...
