Seasonal Effect of a Small Hydropower Plant on Benthic Biofilm Microbial Community Structure and Predicted Functional Potential

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Biofilm microbial composition varies significantly; diversity is higher in spring and autumn. The dewatered reach shows the broadest niche and dominant stochastic assembly. Seasonal assembly shift: deterministic in summer, stochastic in winter. Nutrient cycling genes vary more among sites than seasons under SHP influence.

Polyhydroxyalkanoate as Next Generation Bioplastics for Sustainability and Circular Energy Management

EcoMat, Volume 8, Issue 9, September 2026.
Circular system converting wastewater sludge (WWS) into PHA bioplastics via acidification and MMC biosynthesis. System highlights LCA framework, showing GWP trade‐offs against fossil plastics and costs of $3–5/kg PHA, ultimately achieving lower carbon footprints and resource recovery for a sustainable bioeconomy.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

High‐Value Utilization of Typical Vanadium‐Bearing Solid Wastes: Mineralogy, Pathways, and Perspectives

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

River Research and Applications, Volume 42, Issue 7, Page 1573-1585, September 2026.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Iron⁃calcium⁃biochar enhanced sludge deep dewatering and sludge⁃based biochar preparation

能源环境保护
Sludge dewatering is a crucial step in sludge disposal and resource recovery. While FeCl3 is commonly used to enhance sludge dewatering, it is ineffective for some residual sludges, resulting in a high moisture content in the sludge cake that fails to ...

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

Safety Science and Technology, Volume 1, Issue 3, September 2026.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Dams and Their Legacies Shape Biogeochemical Evolution of Riparian Sediments

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Dams and their legacies have substantially altered riparian ecosystems worldwide and these effects could persist for decades or centuries into the future. However, how biogeochemical characteristics of riparian sediments evolve with depth and time post dam removal is poorly understood.
