Light–dark conditions drive variability in phosphorus and ammonium uptake by epilithic biofilms along the main stem of a Mediterranean river

Limnology and Oceanography, EarlyView.
Abstract Benthic biofilms on cobbles (i.e., epilithic biofilms) control the uptake of soluble reactive phosphorus (SRP) and ammonium (NH4+) in headwater streams. However, nutrient uptake by biofilms in higher‐order rivers, particularly those affected by anthropogenic nutrient inputs and hydrological regulation, remains poorly understood.

Evaluation of a modified sequential P extraction protocol: Quantification of Fe(II)‐P as a separate phase in seven different freshwater sediments

Limnology and Oceanography: Methods, EarlyView.
Abstract Sequential phosphorus (P) extraction (SPE) is a well‐established and widely applied method for quantitatively and qualitatively determining the critical nutrient P in freshwater sediments. It allows the estimation of P bioavailability and facilitates the evaluation of the long‐term effects of eutrophication mitigation measures.

Bio‐Based Nanofiber Membranes for Effective Air Filtration: Fabrication and Evaluation of Flame‐Retardant Behavior, Mechanical Properties, and Filtration Performance

Macromolecular Materials and Engineering, EarlyView.
The membranes are fabricated from a biodegradable polymer and a bio‐based and inorganic flame‐retardant material in optimized electrospinning conditions to control flammability. Hydrogen bonds between the applied materials improved the mechanical properties and potential exposure to fire. These membranes offer higher filtration quality compared to that

Vapor Deposition of Polymer Structures: From 2D Surface Coatings and Surface Microstructures to 3D Building Blocks and Structural Monoliths

Macromolecular Rapid Communications, EarlyView.
This review discusses the progress of vapor‐deposited polymer structures, from simple thin films and surface microstructures to complex 3D architectures and monoliths. It covers fabrication methods, polymerization mechanisms, and processes for fabricating these structures. The applications of these polymers are discussed, focusing on device integration
