Selective Co‐Assembly of Water‐Soluble Conjugated Polyelectrolyte with Discernable Fluorescence Modulation for Antibiotic Detection

Advanced Sensor Research, EarlyView.
PQx‐Ph, a water‐soluble conjugated polyelectrolyte, enables rapid and selective fluorescence‐based detection of structurally distinct antibiotics via supramolecular assembly modulation. It achieves nanomolar sensitivity under mild conditions and preserves reliable sensing performance across NOM‐rich and biologically relevant water matrices, supporting ...

Sustainable 3D‐Printed Platforms with Durable Photocatalytic Coatings for Efficient Water Treatment

Advanced Sustainable Systems, EarlyView.
This work presents a sustainable 3D‐printed scaffold with a bioinspired, wear‐resistant surface for photocatalyst coatings. The nano‐enabled scaffolds demonstrate exceptional stability, maintaining performance after 30 cycles of chemical regeneration and UV irradiation, while achieving a removal efficiency of 93%.

Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters

Frontiers in Microbiology, 2018
Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

HARMLESS Early Warning System for Advanced Materials

Advanced Sustainable Systems, EarlyView.
The HARMLESS Early Warning System tackles Advanced Materials (AdMa) risk governance by providing a framework, organised in two tiers, underpinned with methods/tools to support risk assessors in the pre‐assessment preceding risk assessment. It allows for initial screening to identify AdMa with concerns considering exposure, hazards, sustainability and ...

Discreteness of populations enervates biodiversity in evolution [PDF]

arXiv, 2010
Biodiversity widely observed in ecological systems is attributed to the dynamical balance among the competing species. The time-varying populations of the interacting species are often captured rather well by a set of deterministic replicator equations in the evolutionary game theory.

Generalized Stoichiometry and Biogeochemistry for Astrobiological Applications [PDF]

arXiv, 2020
A central need in the field of astrobiology is generalized perspectives on life that make it possible to differentiate abiotic and biotic chemical systems. A key component of many past and future astrobiological measurements is the elemental ratio of various samples.

The ecology of flows and drift wave turbulence in CSDX: A model

, 2018
This paper describes the ecology of drift wave turbulence and mean flows in the coupled drift-ion acoustic wave plasma of a CSDX linear device. A 1D reduced model that studies the spatiotemporal evolution of plasma mean density n¯, and mean flows v¯y and
