The discovery of novel quaternary intermetallic compounds RMoSiC (R = Y, Gd) in the R-Mo-Si-C system is reported. Their crystal structure was investigated using single-crystal X-ray diffraction. It is shown that the YMoSiC and GdMoSiC compounds crystallize in the tetragonal space group P4/mbm (Pearson symbol tP12) with unit-cell parameters a = 6.

In this article, we report on the complex crystal structure and physical properties of CrSnS, a -type magnetic semiconductor with a low energy band gap and low thermal conductivity. Importantly, we demonstrate that the high level of structural complexity is related to the coexistence of two sublattices: a host lattice, [CrSnS], characterized by a mixed Sn/Cr occupancy of its cationic sites, and a guest lattice characterized by [SnS] chains, containing Sn cations only, closely related to the ones encountered in the orthorhombic SnS compound.

The use of absorbable material in fixation avoids the need for a second surgery, which would otherwise be required to remove osteosynthesis material. The authors of the present manuscript have already demonstrated that absorbable sutures ensure the stable fixation of bone segments in patients up to 24 months of age.

Objective: To estimate the incidence of revision CTR following ECTR compared with OCTR in a national cohort.
