Neutron-Inelastic-Scattering Peak by Dissipationless Mechanism in the s++ -wave State in Iron-based Superconductors

, 2011
We investigate the neutron scattering spectrum in iron pnictides based on the random-phase approximation in the five-orbital model with a realistic superconducting (SC) gap, Delta=5meV.

Common misconceptions in crystallography and crystal optics

Journal of Applied Crystallography, EarlyView.
Six recurrent misconceptions in crystallography, some involving mineral and crystal optics, are analyzed and discussed. The explanation of these and similar misconceptions could serve as educational resources for teachers.Did you know that an X‐ray diffraction pattern is not a spectrum?

Polarized Neutron Inelastic Scattering Study of the Anisotropic Magnetic Fluctuations in the Quasi-1D Ising-like Antiferromagnet TlCoCl$_3$

, 2006
Polarized neutron inelastic scattering experiments have been carried out in the quasi-1D Ising-like antiferromagnet TlCoCl$_3$. We observed the longitudinal magnetic fluctuation $S_{zz} (Q, \omega)$ for the spin-wave excitation continuum, which has not ...

Selective Reductive Amination of Carbonyls to Primary Amines Under Ambient Conditions Over Rh/MFM‐300(Cr)

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Rh/MFM‐300(Cr) enables highly selective reductive amination of biomass‐derived and other carbonyls with NH3 and H2 to affordprimary amines with up to 99% selectivity under ambient conditions (25 °C, 1 atm). Abstract The synthesis of organic amines via reductive amination of biomass‐derived carbonyl compounds is an important target for sustainable ...

Towards understanding the magnetic properties of the breathing pyrochlore compound Ba3Yb2Zn5O11through single-crystal studies

npj Quantum Materials, 2022
Ba3Yb2Zn5O11 is exceptional among breathing pyrochlore compounds for being in the nearly-decoupled limit where inter-tetrahedron interactions are weak, hosting isolated clusters or molecular magnet-like tetrahedra of magnetic ytterbium (Yb3+) ions.

Crystal Structures and Intermolecular Interactions in α$\alpha$‐ and β$\beta$‐phosgene

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Despite its notorious reputation as a war gas, phosgene (COCl2${\rm COCl}_2$) is one of the most important intermediate chemicals in industry. In this study, we present the crystal structures of two phosgene polymorphs as deduced from powder neutron diffraction and show which intermolecular interactions stabilise the different modifications.

Dynamics of cubic-tetragonal phase transition in KNbO$_3$ perovskite

, 2004
The low-energy part of the vibration spectrum in KNbO$_3$ was studied by cold neutron inelastic scattering in the cubic phase. In addition to acoustic phonons, we observe strong diffuse scattering, which consists of two components. The first one is quasi-

Tagged spectator DIS on a polarized spin-1 target [PDF]

, 2016
We discuss the process of deep-inelastic electron scattering (DIS) on the polarized deuteron with detection of a nucleon in the nuclear fragmentation region ("spectator tagging"). We cover (a) the general structure of the semi-inclusive DIS cross section

Acoustic Nature of the Boson Peak in Vitreous Silica

, 1999
New temperature dependent inelastic x-ray (IXS) and Raman (RS) scattering data are compared to each other and with existing inelastic neutron scattering data in vitreous silica (v-SiO_2), in the 300 - 1775 K region.
