Abstract How to fabricate durable superhydrophobic materials for cyclic oil/water separation solve oil-induced pollutions is still a problem. Herein, we fabricated Superhydrophobic Stainless Steel Mesh (SH-SSM) with nano/micro flower-like sheets by self-assembly of zinc stearate the various mixtures. The SH-SSM exhibits superhydrophobicity against static or dynamic treatments. In virtue SH-SSM,...

In North America, investment in unconventional oil extraction has increased due to the scarcity of conventional reserves. The rapid production growth has induced an extensive transportation activity, sometimes using aging pipelines and inadequate rail tank cars. Without surprise, in recent years, several high impact oil spills have occurred, as the taken place in Lac-Mégantic, the worst terrest...

Adult coho salmon Oncorhynchus kisutch return each autumn to freshwater spawning habitats throughout western North America. The migration coincides with increasing seasonal rainfall, which in turn increases storm water run-off, particularly in urban watersheds with extensive impervious land cover. Previous field assessments in urban stream networks have shown that adult coho are dying premature...

Nuclear magnetic resonance (NMR) diffusion-relaxation correlation experiments (D-T2) are widely used for the petrophysical characterisation of rocks saturated with petroleum fluids both in situ and for laboratory analyses. The encoding for both diffusion and relaxation offers increased fluid typing contrast by discriminating fluids based on their self-diffusion coefficients, while relaxation ti...

Measuring average quantities in complex mixtures can be challenging for mass spectrometry, as it requires ionization and detection with nearly equivalent cross-section for all components, minimal matrix effect, and suppressed signal from fragments and aggregates. Fragments and aggregates are particularly troublesome for complex mixtures, where they can be incorrectly assigned as parent ions. He...
