Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

Advanced Materials Technologies, EarlyView.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Changing fate of large industrial investments during the Gomułka Period (1956–1970)

Studia Historiae Oeconomicae
The Gomułka period of fourteen years includes one of the investment cycles characteristic of the centrally managed economy in Poland. After an initial, short period of stabilization of outlays, in the years 1959–1969 they were significantly increased ...

Kinetically Controlling Surface Atom Arrangements in Thermally Robust, Amorphous High‐Entropy Alloy Nanoparticles by Solvent Selection

Advanced Science, EarlyView.
This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...
