The long search for materials carrying quantum spin liquid states has recently led to -RuCl, a layered honeycomb Mott insulator with substantial spin-orbit coupling. Often, controlled doping of materials with strong 2D character generates new exotic properties as well as a better understanding of the parent compound. This paper shows that the intercalation compound KRuCl sustains a peculiar charge disproportionation into formally Ru and Ru. Every Ru with one hole in the t shell is surrounded by Ru where the t level is full and magnetically inert. Thus each type of Ru sites forms a triangular lattice and nearest-neighbor interactions of the original honeycomb are blocked.

Electronic instabilities in transition metal compounds can lead to ground states containing orbital molecules when direct metal-metal orbital interactions occur. The largest reported orbital molecules are V717+ heptamers that emerge below a 700 K charge ordering transition in the spinel AlV2O4. However, x-ray total scattering analysis shows that the apparent heptamers are actually pairs of spin-singlet V39+ trimers and V48+ tetramers, and that these orbital molecules persist to at least 1100 K although they become ‘hidden’ by disorder in the average cubic structure above the charge ordering transition.

Binary phase field crystal (PFC) models have been successful in describing a broad selection of phenomena in binary alloy materials: eutectic and dendritic solidification, the Kirkendall effect, clustering, solid state precipitation, and many more. In this paper, authors present improvements to the binary structural PFC model and show that these improvements allow us to model new material phase diagrams. They apply their improved model to study the kinetics of precipitation from a liquid solution where they observe a two-step nucleation pathway. This agrees with recent experimental observations in which spinodal decomposition precedes nucleation in solute-rich domains. They also find a phenomenon not previously described in the literature in which precipitate growth is accelerated in the presence of uncrystallized, solute-rich liquid domains.

Strain tomography has the potential to dramatically transform the way in which experimental mechanics is carried out. In much the same way that regular computed tomography transformed medicine and other sciences, a full-field approach to measuring triaxial strain may have an impact across a range of areas. This paper details a practical demonstration of reconstructing a biaxial elastic strain fields from Bragg-edge neutron strain images in a nontrivial steel sample subject to loading. This demonstration provides a basis for future efforts focussed on extending to three-dimensional strain fields, as well as a broader class of strain fields (e.g., residual strain).
