Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Inhibitory effect of nitrite on iron sulfide dissolution at high pH

Journal of the American Ceramic Society, Volume 108, Issue 6, June 2025.
Abstract Oxidation reactions of iron sulfide‐bearing aggregates have been increasingly recognized as a significant cause of concrete deterioration worldwide. Yet there is a lack of mitigation strategies to control the reactions. This work investigates the effectiveness of nitrate‐ and nitrite‐based admixtures in inhibiting the dissolution of iron ...

Frequent Millennial‐Scale Oceanic Redox Oscillations Recorded by Negative Pyrite Δ33S: Implications for Phanerozoic Extinctions

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Phanerozoic extinctions may have been influenced by oceanic redox oscillations, as indicated by mixing‐induced negative pyrite Δ33S (Δ33Spy). However, the frequencies, intensities, and timescales of these oscillations remain elusive. Here, we measured stratigraphic Δ33Spy from the currently anoxic Cariaco Basin, spanning ∼0.6 million years ...
