To address the inefficiency and selectivity limitations of conventional extraction methods, this study synthesized a core-shell composite metal-organic framework (MOF) material, KCoFC@UiO-66, via a solvothermal coordination strategy. The material synergistically integrates the ion-exchange capability of potassium cobalt hexacyanoferrate (KCoFC) with the hierarchical porosity and structural stability of zirconium 1,4-dicarboxybenzene MOF (UiO-66). Structural characterization confirmed the core-shell architecture, where the KCoFC core facilitates selective Rb capture via ion exchange and cyano coordination, while the UiO-66 shell enhances Rb enrichment through electrostatic interactions and size-selective sieving. Adsorption kinetics followed a pseudo-second-order model, indicating chemisorption dominance, while isotherm studies aligned with Freundlich and Dubinin-Radushkevich models, revealing heterogeneous multilayer adsorption. The composite demonstrated remarkable selectivity for rubidium, achieving a recovery rate of 98.7 % from lithium tailing leachates, along with notable regeneration stability, retaining 86.2 % of its capacity after five cycles. This performance can be ascribed to the ability of UiO-66 to inhibit the aggregation of KCoFC and to the effects of pore confinement.

Monitoring short-rotation poplar plantations requires frequent updates, which are infeasible with conventional National Forest Inventories (NFIs). Remote sensing (RS) has emerged as a highly effective tool for monitoring the structural variables of poplar plantations. This study aims to estimate the carbon stocks of poplar plantations in the Padan Plain, which spans approximately 46,000 km<sup>2</sup> in northern Italy. To achieve this, we developed a 10m high-resolution canopy height model (CHM) using a deep learning U-Net approach, with Sentinel-1 and Sentinel-2 multi-band imagery as predictors for GEDI waveforms derived tree height. The U-Net CHM for 2021 was evaluated with external validation data from NFI plots, achieving a mean absolute error of 2.6 m. Using annual poplar plantations data in the survey area, along with a poplar-specific yield table derived from terrestrial laser scanning, we applied the U-Net CHM to predict key forestry variables, including diameter at breast height (DBH), growing stock volume (GSV), aboveground biomass (AGB), and carbon stock (CS) in all stands. Results were compared with external validation data from NFI, yielding RMSE values of 30.7 %, 46.2 %, and 63.2 % for DBH, GSV, and AGB, respectively.

In addition, market responses to changes in wood supply following altered forest management by one region induce climate relevant changes in form of compensatory roundwood harvest outside the region, and thus forest carbon leakage. This study presents a global climate change mitigation assessment of the forest sector, accounting for market-effects leakage. We use a global forest sector model, wood flow analysis and life cycle inventory data to assess the impact of forest management changes on climate change mitigation, with a focus on Sweden. Results suggest decreased wood harvesting causes global net climate change mitigation until 2070, despite forest carbon leakage, forgone wood product carbon storage and forgone substitution effect potentials. Increasing domestic wood removals induces global additional emissions until 2100. Additional domestic wood product consumption is climate beneficial which however depends on substitution effects actually materializing. Roundwood harvest leakage ranges from 40 % to 60 % and forest carbon leakage from 50 % to 80 %. Leakage effects occur mainly in North America and Asia, with a gradual shift towards Latin America over time.

Here, the effect of Fe(III) dosing on granule formation and anammox-driven nitrogen removal over a 110-day continuous operation was investigated. Fe(III) supplementation enhanced interactions with extracellular polymeric substances (EPS), transforming flocculent biomass into highly porous granules and yielding a 67.9 % increase in specific anammox activity (SAA). During the first 30 days of Fe(III) dosing, the Zeta potential shifted from -12.0 to -9.3 mV and EPS content surged from 32.8 mg/g VSS to 49.0 mg/g VSS, accelerating primary floc aggregation. Subsequently, the protein-to-polysaccharide ratio of EPS escalated from 1.7 to 5.3, reflecting a transition from a carbohydrate-rich, hydrophilic gel to a protein-dominated, hydrophobic network that facilitated granulation. Micro-computed tomography revealed that smaller (1.5 mm) granules exhibited dense architectures, whereas larger (2.5 mm) granules developed internal cavities as a result of mass transfer limitations, approaching structural fragmentation. Metagenomic analysis showed that Fe(III) upregulated pathways for hydrophobic amino acids (e.g., isoleucine, leucine, valine) synthesis and downregulated polysaccharide biosynthesis, thereby increasing EPS hydrophobicity and promoting granulation. The observed SAA enhancement was linked to Fe(III)-dependent activation of iron-containing enzymes (e.g., hzs ABC), cytochrome c maturation, and Fe-S cluster assembly. Concurrently, the relative abundance of Ca. Kuenenia rose from 14.1 % during aggregation to 18.6 % after sludge granulation.
