Bullion production in imperial China and its significance for sulphide ore smelting world-wide [PDF]

, 2015
Gold and silver production was of major importance for almost all ancient societies but has been rarely studied archaeologically. Here we present a reconstruction of a previously undocumented technology used to recover gold, silver and lead at the site ...

Porous Bi2S3 Bulk With Excellent Thermoelectric Performance by Solid States Replacement and Low Melting‐Point Metal Volatilization

Advanced Materials, EarlyView.
By introducing FeCoNi medium‐entropy alloy, the bismuth sulfide (Bi2S3) material achieves a record‐high ZT of 1.1 at 773 K, owing to the solid‐states replacement reaction and the volatilization of low melting‐point metal. This strategy is also applicable to other sulfur‐based thermoelectric materials.

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

Advanced Science, EarlyView.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

Towards Climate Neutrality by 2050: Role of Aluminum for Short‐ and Long‐Term Energy and Hydrogen Storage

Advanced Energy Materials, EarlyView.
The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...
