Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

open access: yesSmall, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Direct Recycling of Nickel Manganese Cobalt Oxides: Impact of Shear Milling on Physicochemical and Electrochemical Performance

open access: yesBatteries &Supercaps, Volume 9, Issue 8, August 2026.
The first step of the direct recycling process of lithium‐ion battery (LIB) cathodes is investigated through shear milling of NMC622 materials. An excessive milling energy could alter particle size and induce crystalline microstrains, leading to electrochemical performance loss.

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 ...

Chemical Risk Assessment in Black Mass Processing Facilities: Addressing Safety in a Critical and Emerging Industry

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A dedicated chemical risk assessment framework for black mass processing across different operational scenarios is proposed. By integrating regulatory hazard classification with a semi‐quantitative probability–severity matrix, the framework provides the first structured tool for risk evaluation and prioritization in black mass facilities, supporting ...
