Stable Isotope Insights into Microplastic Contamination within Freshwater Food Webs.
Published in Environmental science & technology
Microplastic pollution and ingestion are ubiquitous phenomena in freshwater ecosystems. However, our understanding of the role of trophic niche in microplastic ingestion is still limited. Here, we quantified the level of microplastic (700 μm to 5 mm) contamination for macroinvertebrates and fish within the Garonne river. We then used stable isotope...
Pickering emulsion stabilized by dual stabilizer: A novel reaction/separation system for methacrolein synthesis
A reaction/separation system composed of water-in-oil Pickering emulsion was constructed for the syn-thesis of methacrolein. The catalyst (diethanolamine acetate) aqueous solution was encapsulated in numerous emulsion droplets which were stabilized by dual stabilizer system and could be recycled and separated from product by filtration. The dual st...

Three-dimensional volumetric monitoring of settling particulate matters on a leaf using digital in-line holographic micr...
Plants are considered as a possible modality to reduce particulate matter (PM) particles from ambient air in an ecofriendly manner. A new precise monitoring technique that can explore interactions between individual PM particles and a leaf surface is necessary to understand the underlying mechanisms of PM removal of plant leaves. In this study, a d...
catchyFOAM : Euler−Euler CFD simulations of fluidized bed reactors with microkinetic modeling of gas-phase and catalytic...
Whereas detailed kinetic models have already been implemented widely in computational fluid dynamics (CFD) simulations of gas-phase processes, CFD modeling of reactive gas-solid processes with detailed kinetics, especially in fluidized bed reactors, is a largely unexplored territory. To fill this gap, for the first time, an Euler-Euler based code, ...
Tuning size and coverage of Pd nanoparticles using atomic layer deposition
...
The morphology evolution of supported palladium nanoparticles (Pd NPs) during plasma-enhanced atomic layer deposition using palladium hexafluoroacetylacetonate (Pd(hfac)(2)) as precursor was investigated using in situ and ex situ X-ray fluorescence (XRF) and grazing incidence small angle X-ray scattering (GISAXS), as well as ex situ scanning electr...
Temperature effects on interdiffusion of Al and U-Mo under irradiation
...
A high-energy Xe ion irradiation experiment was conducted to investigate the temperature dependence of interdiffusion in bilayer Al-UMo samples under irradiation. The amount of interdiffusion achieved at a fixed dose with the increase of temperature showed a clear transition at 175 degrees C (with an estimated error in the range of +/- 10 degrees C...
Rheological behavior of cement paste with nano-Fe3O4 under magnetic field : magneto-rheological responses and conceptual...
The magneto-rheological responses of cement paste with nano-Fe3O4 particles are experimentally investigated. The estimated magneto-dynamic force between two neighboring nanoparticles and equilibrium movement velocity of the nanoparticles in cement-based suspensions are calculated. Results show that the nanoparticles have a potential to move to form...
Pion–kaon femtoscopy and the lifetime of the hadronic phase in Pb−Pb collisions at sNN=2.76 TeV
...
In this paper, the first femtoscopic analysis of pion–kaon correlations at the LHC is reported. The analysis was performed on the Pb–Pb collision data at sNN=2.76 TeV recorded with the ALICE detector. The non-identical particle correlations probe the spatio-temporal separation between sources of different particle species as well as the average sou...
