4D synchrotron X-ray tomographic quantification of the transition from cellular to dendrite growth during directional solidification
Abstract Solidification morphology directly impacts the mechanical properties of materials; hence many models of the morphological evolution of dendritic structures have been formulated. However, there is a paucity of validation data for directional ...

On strain hardening mechanism in gradient nanostructures
Abstract Experiments have shown that a gradient design, in which grain size spans over four orders of magnitude, can make strong nanomaterials ductile. The enhanced ductility is attributed to the considerable strain hardening capability obtained in...

Reduction of phonon mean free path: From low-temperature physics to room temperature applications in thermoelectricity
Abstract It has been proposed for a long time now that the reduction of the thermal conductivity by reducing the phonon mean free path is one of the best way to improve the current performance of thermoelectrics. By measuring the thermal conductance ...

Hidden secrets of deformation: Impact-induced compaction within a CV chondrite
Abstract The CV3 Allende is one of the most extensively studied meteorites in worldwide collections. It is currently classified as S1—essentially unshocked—using the classification scheme of Stöffler et al. (1991), however recent modelling suggests...
