A geophysical study of a pockmark in the Nyegga region, Norwegian Sea [PDF]

, 2008
Over the last decade pockmarks have proven to be important seabed features that provideinformation about fluid flow on continental margins. Their formation and dynamics are stillpoorly constrained due to the lack of proper three dimensional imaging of ...

Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

Advanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Numerical simulation on deposition evolution of natural gas hydrate in pipeline

You-qi chuyun, 2022
The traditional Euler-Euler fluid model is to predict the flow and deposition of two phases by approximating the hydrate particles as a fluid phase, but does not consider the effect of particle formation caused by phase change in the flow process. Herein,
