Identifying Saharan dust driven export of biogenic material in the ultraoligotrophic eastern Mediterranean Sea

Frontiers in Marine Science
To assess the effects of dust deposition on the strength of the biological pump in the Mediterranean Sea by acting as fertilizer and/or ballasting agent, we analyzed fluxes of mineral dust, particulate organic carbon (POC) and inorganic carbon (PIC), and

Image-based global analysis of the biological carbon pump

, 2023
La pompe à carbone biologique (PCB) joue un rôle central dans le cycle global du carbone océanique, en transportant le carbone de la surface vers les profondeurs et en le séquestrant pendant de longues périodes. Ce travail vise à analyser deux acteurs clés de la PCB : le zooplancton et les particules. Pour cela, nous utilisons les données d'imagerie in

Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

Advanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

Advanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Municipal wastewater treatment and associated bioenergy generation using anaerobic granular bed baffled reactor [PDF]

, 2017
This study assesses a modified anaerobic granular bed baffled reactor (GRABBR) which was assessed for municipal wastewater treatment at high organic loading rates (chemical oxygen demand ≥ 1,100 mg/l) under varying temperatures.

Global distribution, quantification and valuation of the biological carbon pump

Nature Climate Change
The biological carbon pump (BCP) sequesters vast amounts of carbon in the ocean, but its importance for conservation, climate finance and international policy has not been properly assessed. Here, using spatial analysis and financial valuation of the BCP service, we estimate that, annually, the BCP adds 2.81 GtC (range 2.44–3.53 GtC) to the ocean with ...

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

Advanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Changes in the particulate organic carbon pump efficiency since the Last Glacial Maximum in the northwestern Philippine Sea

Quaternary Science Advances
Changes in bottom and pore water oxygenation over glacial – interglacial cycles have influenced the ocean's capacity to store particulate organic carbon regardless of its source, either the marine primary productivity or the continent-to-ocean transfer ...
