Article Abstract
Recycling treatments of spent Li-ion batteries (LIBs) have become a global focus. However, traditional industrial recycling methods would result in high energy consumption and significant pollution. Eco-friendly techniques can improve resource recovery efficiency, simplify subsequent processes, and enhance product quality. Herein, this spotlight reviews recent advances in the several eco-friendly separation technologies of spent LIBs. First, we investigate the complex active interfacial issues of active material and current collector on restricting the separation process. Subsequently, the working mechanism and separation performances of various separation technologies are comprehensively compared and discussed from multiple perspectives. The existing challenges and limitations associated with each strategy are also critically analyzed. At last, we offer a crucial direction for the green recycling of spent LIBs. This spotlight may not only promote the development of resource circularity but also lay a foundation for building a sustainable battery industry chain.

Earth and Environmental Sciences, University of Minnesota-Twin Cities, Minneapolis, Minnesota 55455, United States.
Mining metals for the advancement of society requires innovative and cost-effective remediation strategies that protect the environment and, ideally, allow for concentration and recovery of metals from waste streams. Microbially mediated strategies that remove metals from aqueous waste streams via sorption and/or oxidation-reduction reactions show promise as eco-friendly, cost-effective solutions. Our objective was to use Mn-oxidizing fungi, isolated from the Soudan Underground Mine State Park, MN, a high-salinity, mine-impacted environment, to sequester transition metals Mn, Co, Cu, and Ni.

This study explores the extraction of polysaccharides from Nostoc commune Vauch. using ultrasonic-assisted three-phase partitioning with deep eutectic solvents (UA-TPP-DES). Response surface methodology was used to determine the optimized UA-TPP-DES conditions as follows: a 1: 2 M ratio of lauric acid to terpineol, 30 min of ultrasonication at 60 °C with 100 W power, 20 % moisture content, 20 % w/w (NH)SO concentration, and a 2: 1 top-to-bottom phase volume ratio.

Perovskite solar cells (PSCs) are rapidly advancing due to their high power conversion efficiencies (PCEs) and low fabrication costs. However, their commercialization is hindered by lead toxicity and the use of expensive materials, such as Spiro-OMeTAD and gold electrodes. This study presents a comprehensive SCAPS-1D simulation-based analysis of 14 perovskite absorber materials, spanning both Pb-based and lead-free compounds, under a unified device architecture using low-cost, nontoxic components: ZnO as the electron transport material (ETM), PEDOT:PSS + WO as a dual hole transport material, and nickel as the back contact.
