Sustainable Metal Mixture Separation From E‐Waste Leaching: Flow‐Based System Approach With Closed‐Loop Reutilization of Organic Ligands

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
This paper reports a flow‐based liquid–liquid extraction system for the selective separation of copper from copper–silver leachates obtained from e‐waste. This process enhances sustainability and reduces solvent consumption. In addition, a ligand/solvent regeneration step is described, enabling copper back‐extraction, recycling of the organic ...

Batteries From Reused, Recycled, and Surplus Materials

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Heavy metals extractability in a soil amended with sewage sludge Extractabilidade de metais pesados em um solo tratado com lodo de esgoto

open access: yesScientia Agricola, 2009
Few investigations have been carried out about the comparison of desorption rate and amount of heavy metals extracted successively by organic acid mixtures mimicking the rhizosphere and routine extractants in sewage sludge-amended soils.

Developing soil‐test‐based sulfur fertilizer recommendations for soybean

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Declining sulfur (S) inputs from atmospheric deposition, combined with greater S removal by high‐yielding crops, have increased concern about S deficiency in soybean [Glycine max (L.) Merr.]. We evaluated soybean yield and leaflet‐S concentration response to six fertilizer‐S rates (0, 11, 22, 34, 45, and 67 kg S ha−1) across 50 site‐years ...

End‐of‐season corn stalk analysis as a tool to fine‐tune potassium and nitrogen management

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Corn (Zea mays L.) requires proper nutrient management for optimal growth, and tissue testing plays an important role in refining recommendations. Corn stalk nitrate test (CSNT) is used to evaluate nitrogen (N) management; however, a comparable plant‐based diagnostic tool for potassium (K) is lacking. This study evaluated extractants for stalk‐

The extracted mind

open access: yesSynthese
Abstract Since Clark and Chalmers advanced “The Extended Mind” in 1998, a persistent dispute evolved on how our tool interactions shape the kind of cognition we have. Extended cognition generally views us as cognitively augmented and enhanced by our tool practices, which shall render our cognitive constitution extended to those tools. Bounded

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...
