Occurrence of the Portevin Le-Chatelier effect in open-cell microcellular Al-2 wt% Mg

Microcellular open-cell metal foams with pores of 75 or 400 pm in diameter and made of pure Al or Al-2 wt% Mg are tested in compression. The aluminum foam exhibits a typical smooth plastic flow and a positive strain rate sensitivity, whereas plastic instab ...

Stresses and Strains in Cruciform Samples Deformed in Tension

Helena Van Swygenhoven, Steven Van Petegem

The stress and strain relationship in the gauge region of six cruciform geometries is studied: the ISO standard geometry with slits in arms, two geometries with thinned gauge areas, two geometries with thinned gauge areas and slits in arms, and one modifie ...

Ribosome profiling and dynamic regulation of translation in mammals

Felix Naef, Cédric Gobet

Protein synthesis is an energy-demanding cellular process. Consequently, a well-timed, fine-tuned and plastic regulation of translation is needed to adjust and maintain cell states under dynamically changing environments. Genome-wide monitoring of translat ...

The evolution of phenotypic plasticity under global change

Emma Mary Gibbin

Marine ecosystems are currently in a state of flux, with ocean warming and acidification occurring at unprecedented rates. Phenotypic plasticity underpins acclimatory responses by shifting the mean phenotype in a population, which may buffer the negative e ...

All natural cork composites with suberin-based polyester and lignocellulosic residue

Véronique Michaud, Hugo De Oliveira

Suberin is an aromatic-aliphatic cross-linked polyester structure which constitutes cell wall structures of cork. It is particularly interesting for its use of monomeric compounds towards renewable bio-based polymers. In this study, the extraction of suber ...

Biodegradable HEMA-based hydrogels with enhanced mechanical properties

Dominique Pioletti, Mohamadreza Nassajian Moghadam

Hydrogels are widely used in the biomedical field. Their main purposes are either to deliver biological active agents or to temporarily fill a defect until they degrade and are followed by new host tissue formation. However for this latter application, bio ...

Heat expandable biopolymers for one-step production of foam core sandwich composites

Yonghoon Yoon

The overall aim of this work has been to develop sustainable solid thermally activated foam precursors suitable for the in-line production of lightweight bio-based foam core sandwich structures with consolidated wood particle facings, using a non-inflammab ...

Model for charge/discharge-rate-dependent plastic flow in amorphous battery materials

William Curtin, Seyed Mostafa Khosrownejad

Plastic flow is an important mechanism for relaxing stresses that develop due to swelling/shrinkage during charging/discharging of battery materials. Amorphous high-storage capacity Li-Si has lower flow stresses than crystalline materials but there is evid ...

Toxicity assessment of pollutants sorbed on microplastics using various bioassays on two fish cell lines

Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca

Microplastics are tiny plastic fragments resulted from runoff and weathering breakdown of larger plastics debris. They represent an emerging concern for marine ecosystems. Microplastics impacts on aquatic life are little studied. These small particles coul ...

Micro-)plastic assessment in freshwater ecosystems and the environment

Luiz Felippe De Alencastro, Florian Faure, Olivier Pompini

While plastic pollution in marine environments is getting better known and is the subject of a continuously growing number of publications, freshwaters still receive too little attention. Some studies worldwide focused on the nature and concentrations of m ...
