In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Research on the Fusion Rule of Water Hammer Durations during Pipeline Shutdown

open access: yesShiyou jixie, 2017
Multiple pump stopping actions will be carried out in the shutdown operation of the long distance pipeline, then many negative pressure and positive pressure water hammers will be generated in the output and input end of the pump separately and will ...

Optimizing intermittent water supply in urban pipe distribution networks

open access: yes, 2016
In many urban areas of the developing world, piped water is supplied only intermittently, as valves direct water to different parts of the water distribution system at different times.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

open access: yesDroplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution

open access: yesEcoEnergy, EarlyView.
A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity [PDF]

open access: yes, 2012
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on ...
