TL;DR: It is reported that the gradient structure in engineering materials such as metals renders a unique extra strain hardening, which leads to high ductility, which is a hitherto unknown strategy to develop strong and ductile materials by architecting heterogeneous nanostructures.

TL;DR: It is found that, on average, net N mineralization and net nitrification rate were increased under experimental warming treatment, and soil heating cable and all-day treatment appeared to be the most effective method on N cycling among all treatment methods.

TL;DR: A three-level heterogeneous grain structure with grain sizes spanning the nanometer to micrometer range, imparting a high yield strength well in excess of 1 GPa leads to a sustainable strain hardening rate, a record-wide hysteresis loop in load−unload−reload stress−strain curve and hence high back stresses.

TL;DR: Investigation of soil N isotopic values along a 3,200 km aridity gradient reveals a hump-shaped relationship between soil δ(15)N and aridity index (AI) with a threshold at AI=0.32, and suggests different controlling factors of N-cycling on either side of the threshold.

TL;DR: In this paper, micro/nanobeam diffraction, together with atomic-resolution imaging and chemical mapping via transmission electron microscopy, can explicitly reveal chemical short-range atomic-scale ordering in a face-centred-cubic VCoNi concentrated solution.
