Abstract:
Thermal expansion of hexagonal diboride CrB2 was investigated via temperature dependence of neutron diffraction, in which zero thermal expansion of unit cell volume was determined from 5 to 130 K with coefficient of thermal expansion of āV = 0.4(1)×10-6 K-1.

Abstract:
In this review, we introduce three neutron scattering techniques, including neutron reflectivity, small angle neutron scat-tering, grazing incidence small angle neutron scattering and quasi-elastic neutron scattering, and their applications on organic photovoltaic materials.

Abstract:
This review summarizes the progress of neutron diffraction in analyzing the structure and revealing the ionic transport mechanisms of antiperovskite SSEs. The structure-function relationships involved in ionic transport pathways, defect chemistry, anion disorder and lattice dynamics are introduced, respectively.

Abstract:
Solventless mechanochemical synthesis by manual grinding was applied to grow imidazole-succinic acid (C3H4N2HOOC-(CH2)2COOH) and imidazole-glutaric acid (C3H4N2HOOC-(CH2)3COOH), which exhibit different electric conducting behaviors and activation energies Ea compared with the reported single crystals obtained from the solution method. This method bears strong capability for tuning conductivities and achieves complete deuteration of the organic salts.

Abstract:
High-performance lithium-deficient Li-rich cathodes have been successfully fabricated and neutron diffraction technique was employed to get insight into their structural characteristics. Based on structural characterization and electrochemical measurement results, the structure-activity relationship of lithium-deficient Li-rich cathodes is constructed.
