Process-Induced Structures of Injection-Molded High-Density Polyethylene-Combining X-ray Scattering and Finite Element Modeling
Marianne Liebi, Manuel Guizar Sicairos
The success of plastics heavily relies on fast melt processing methods used for large-scale industrial manufacturing, including injection molding. The hierarchical structure of the solid polymer depends on material selection combined with processing condit ...
Amer Chemical Soc2024Searching for the Thinnest Metallic Wire
One-dimensional materials have gained much attention in the last decades: from carbon nanotubes to ultrathin nanowires to few-atom atomic chains, these can all display unique electronic properties and great potential for next-generation applications. Exfol ...
Amer Chemical Soc2024Multilayer diffusion-barrier composites based on microfibrillated cellulose from wood, bacterial and algae sources
This work is driven by the effort towards increased environmental sustainability and aims to develop a new food packaging material based on renewable materials, and more specifically cellulose as the most abundant biomass resource on Earth. Focus was on mi ...
EPFL2024Reinforced Supramolecular Networks of End Functionalized Polymers for Tailored Thermomechanical Property Profiles
Thermoset rubbers give rise to elastomers with tunable stiffness and high resilience but are not recyclable. Thermoplastic elastomers can address this problem but their broad applicability is impeded by either limited operating temperatures or inferior ela ...
EPFL2023Scanning Small-Angle X-ray Scattering of Injection-Molded Polymers: Anisotropic Structure and Mechanical Properties of Low-Density Polyethylene
Marianne Liebi, Manuel Guizar Sicairos
Injection molding is known to create a layered anisotropicmorphologyacross the sample thickness due to varying shear and cooling ratesduring the manufacturing process. In this study, scanning small-angleX-ray scattering was used to visualize and quantify t ...
AMER CHEMICAL SOC2023Polyethylene wear of dual mobility cups: a comparative analysis based on patient-specific finite element modeling
Alexandre Terrier, Ehsan Sarshari, Matthieu Boubat
Purpose Concerns remain about potential increased wear with dual mobility cups related to the multiple articulations involved in this specific design of implant. This finite element analysis study aimed to compare polyethylene (PE) wear between dual mobili ...
SPRINGER2022Quantified Effects of Multiple Parameters on Inputs and Potential Sources of Microplastics from a Typical River Flowing into the Sea
Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu
As an important connection of terrestrial and marine ecosystems, rivers input multitudinous (micro)plastics into the oceans. However, comparisons of field and estimated riverine inputs of (micro)plastics and contributions of multiple parameters are limited ...
2022Direct encapsulation of biomolecules in semi-permeable microcapsules produced with double-emulsions
Sebastian Maerkl, Grégoire Michielin
Compartmentalization can serve different purposes such as the protection of biological active substances from the environment, or the creation of a unique combination of biomolecules for diagnostic, therapeutic, or other bioengineering applications. We pre ...
NATURE PORTFOLIO2022Novel tooling for direct melt impregnation of textile with variotherm injection moulding: Methodology and proof of concept
Véronique Michaud, Vincent Werlen, Christian Rytka
Thermoplastic compression resin transfer moulding coupled with injection moulding is an appealing process for the production of thermoplastic composites. However, its implementation at an industrial scale remains challenging as variotherm injection mouldin ...
SAGE PUBLICATIONS LTD2022Development and Characterization of Rice Husk and Recycled Polypropylene Composite Filaments for 3D Printing
Nowadays the use of natural fiber composites has gained significant interest due to their low density, high availability, and low cost. The present study explores the development of sustainable 3D printing filaments based on rice husk (RH), an agricultura ...
