TL;DR: It is shown that heat-carrying phonons with long mean free paths can be scattered by controlling and fine-tuning the mesoscale architecture of nanostructured thermoelectric materials, and an increase in ZT beyond the threshold of 2 highlights the role of, and need for, multiscale hierarchical architecture in controlling phonon scattering in bulk thermoeLECTrics.

TL;DR: In this article, the relationship between precipitation phenomena, grain size and mechanical behavior in a complex precipitation-strengthened alloy system, Al 7075 alloy, a commonly used aluminum alloy, was selected as a model system in the present study.

TL;DR: A data compilation technique for the generation of composition profiles in the vicinity of interfaces in a geometrically independent way is outlined, applied to quantitative determination of interfacial segregation of silver at a MgO/Cu(Ag) heterophase interface.

TL;DR: In this article, the authors investigated yield strength at ambient temperature and creep resistance between 225 and 300°C in dilute Al(Sc) alloys containing coherent Al3Sc precipitates, which were grown by heat-treatments to radii in the range 1.4-9.6 nm.

TL;DR: In this paper, the authors describe four criteria for the selection of alloying elements capable of producing castable, precipitation-strengthened Al alloys with high-temperature stability and strength.
