Progress in low‐temperature partial nitritation/anammox coupled with enhanced biological phosphorus removal: Development, mechanisms, and optimization strategies

Abstract With increasing concerns over eutrophication control and carbon‐neutral wastewater treatment, simultaneous nitrogen and phosphorus removal under low‐temperature conditions remains a critical challenge. Conventional biological nutrient removal processes suffer from high e...

Characteristics of dissolved organic matter and greenhouse gas emissions in the Yarlung Tsangpo, a large transboundary river

Rivers are significant emitters of greenhouse gases (GHGs) such as CO 2 , CH 4 , and N 2 O. However, the spatial variability of riverine GHG fluxes and their relationship with dissolved organic matter (DOM) characteristics—such as concentration, composition, sources, and properti...

Modeling the carbon landscape of Northwest China: from climatic controls to vegetation-driven hotspots

Abstract Background As a sensitive response area to global climate change, the terrestrial ecosystem carbon sink function of the Northwest Arid Region of China is not only a core element in constructing the regional ecological security barrier but also a crucial strategic fulcrum...

Bisphosphonic Acid Functionalized Conjugated Polymer Enables Synergistic Co-Assembly for Fabricating Efficient Perovskite Solar Cells

Abstract The practical application of self-assembled monolayers (SAMs) in inverted perovskite solar cells (PSCs) is severely hindered by insufficient substrate binding, inhomogeneous coverage, and limited defect passivation at the buried interface. Herein, we report the synthesis...

Scaling of Urban 3D Form with Emissions and GDP in Chinese Cities
