Where Can Aluminum Go When Batteries Die?

open access: yesAdvanced Science, EarlyView.
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

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

open access: yesStudia 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 ...

High‐Entropy Ferroelectric‐Ferroelastic Hybrid for Ultrahigh and Temperature‐Insensitive Dielectric Energy Storage

open access: yesAdvanced Science, EarlyView.
A high‐entropy ferroelectric‐ferroelastic hybrid perovskite material is successfully developed, in which a unique hybrid architecture, ferroelastic microdomainsembedded with randomly dispersed polar nanoregions, endows the ceramic with polar heterogeneity as well as lowered polarization hysteresis, delayed saturation polarization and enhanced breakdown

Deformable Eutectic Alloy With Near‐Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects

open access: yesAdvanced Science, EarlyView.
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Hierarchically Porous Nitrogen‐Doped Carbon with High Conductivity for Rapid and Efficient Cr(VI) Reduction

open access: yesAdvanced Science, EarlyView.
The d‐PNC(1100, 10%) catalyst, synthesized via a zinc‐based ionic liquid self‐sacrificing pore‐forming strategy to create a defect‐rich, hierarchical, nitrogen‐doped porous structure, enhances conductivity, promotes rapid mass transfer and synergistic catalytic activity, driving efficient Cr(VI) reduction in OA solution to generate Cr(III)‐OA complexes.
