Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

Advanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Phosphorus fractions and correlation with soil attributes under no-tillage and crop-livestock integration systems in Cerrado of Goias

Semina: Ciências Agrárias, 2015
The objectives of this study were to evaluate the fractions of organic phosphorus (P) and inorganic soil, and to determine the remaining phosphorus (Prem) and correlate the fractions of P with some soil attributes in areas with different land use systems

A Worm‐Inspired Origami Robot with Multimodal Locomotion for Adaptive Mobility in Complex Pipeline Environments

Advanced Science, EarlyView.
An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

An Artificially Selected Cytokinin‐Pathway Transcription Factor Balances Soybean Yield and Pathogen Resistance

Advanced Science, EarlyView.
A cytokinin pathway transcription factor, RR2b, was artificially selected during soybean domestication and improvement based on its differential transcriptional activity, which correlates with ATT repeat polymorphisms in its promoter. RR2b balances yield and defense by fine‐tuning its expression level and offers a promising target for decoupling trade ...

Acidification-driven soil phosphorus fractionation following long-term fertilization and cessation at ukulinga mesic grassland in South Africa

Scientific Reports
Long-term fertilisation can alter soil nutrient dynamics, yet the persistence and redistribution of phosphorus (P) fractions following the cessation of combined nitrogen (N) and P inputs remain poorly understood. This study investigated how 71 years of P-

Resolving the spatial variability of soil N using fractions of soil organic matter

, 2012
The spatial variability of soil nitrogen (N) mineralisation has not been extensively studied, which limits our capacity to make N fertiliser recommendations. Even less attention has been paid to the scale-dependence of the variation.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Influences of nitrogen input forms and levels on phosphorus availability in karst grassland soils

Frontiers in Sustainable Food Systems
The availability of soil phosphorus (P), a crucial nutrient influencing plant productivity and ecosystem function, is impacted by continuously increasing nitrogen (N) enrichment, which changes the soil P cycle.
