Insights into the Horizontal and Vertical Profiles of Microplastics in a River Emptying into the Sea Affected by Intensive Anthropogenic Activities in Northern China

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

Studies focused only on surface water may underestimate microplastic abundance in aquatic environments. This was the first survey to investigate the vertical (surface, intermediate, and bottom waters) distribution and composition of microplastics (MPs) in ...

Fabrication and Characterization of High Aspect Ratio Amorphous Silicon Based Microchannel Plates

Christophe Ballif, Nicolas Würsch, Janina Christine Isabelle Löffler, Samira Alexandra Frey, Mohammad Beygi

This contribution focuses on the fabrication and characterization of microchannel plates made of hydrogenated amorphous silicon (AMCPs). Flexible fabrication processes and the semi-conducting nature of amorphous silicon could give these detectors the advan ...

Effects of spanwise confinement on stratified shear instabilities

François Gallaire, Yves-Marie François Ducimetière

We consider the influence of transverse confinement on the instability properties of velocity and density distributions reminiscent of those pertaining to exchange flows in stratified inclined ducts, such as the recent experiment of Lefauve et al. [J. Flui ...

Effects of Anthropogenic Discharge and Hydraulic Deposition on the Distribution and Accumulation of Microplastics in Surface Sediments of a Typical Seagoing River: The Haihe River

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

Microplastics pollution in river systems has generated great concern; however, few studies have focused on the contributions of multiple influencing factors to microplastics in river systems. In the current study, we utilized data on microplastics in surfa ...

Reversibly Cross-Linking Polymer Brushes Using Interchain Disulfide Bonds

Harm-Anton Klok, Piotr Mocny

The introduction of interchain cross-links in surface-grafted polymer brushes increases the robustness and mechanical properties of these thin polymer films. In most cases, cross-linked polymer brushes contain permanent interchain cross-links. The use of r ...

Propagation of a planar hydraulic fracture perpendicular to the isotropy plane of a transversely isotropic material

Brice Tanguy Alphonse Lecampion, Haseeb Zia, Fatima-Ezzahra Moukhtari

We investigate the case of a hydraulic fracture (HF) propagating perpendicular to the isotropy plane of a transversely isotropic material: a relevant configuration for the growth of HFs in sedimentary rocks where fractures are propagating vertically across ...
