Comprehensive analysis of ordering in CoCrNi and CrNi alloys.

Chemical Short-Range Order (CSRO) has attracted recent attention from many researchers, creating intense debates about its impact on material properties. The challenges lie in confirming and quantifying CSRO, as its detection proves exceptionally demanding, contributing to conflicting data in the literature regarding its true effects on mechanical properties. Our work uses high-precision calorimetric data to unambiguously prove the existence and, coupled with atomistic simulations, quantify the type of CSRO.

Unravelling the crystal structure of NdWO and NdWMoO mixed ionic electronic conductors.

Mixed ionic electronic conducting ceramics Nd WO (δ is the oxygen deficiency) provide excellent stability in harsh environments containing strongly reactive gases such as CO, CO, H, HO or HS. Due to this chemical stability, they are promising and cost-efficient candidate materials for gas separation, catalytic membrane reactors and protonic ceramic fuel cell technologies. As in La WO, the ionic/electronic transport mechanism in Nd WO is expected to be largely controlled by the crystal structure, the conclusive determination of which is still lacking.
