Extensive investigation of the ultrastructure of kink-bands in flax fibres
Fibres from annual plants are a sustainable alternative for glass fibres in composite manufacturing. However, both synthetic fibres, such as carbon fibres, and cellulosic fibres exhibit heterogeneities along their lengths, which appeared as localized morphological disorientations known as kink-bands. In plant fibres, kink-bands occur due to growing...
Double fenestrated physician-modified stent-grafts for total aortic arch repair in 50 patients.
Published in Journal of vascular surgery
Our aim was to evaluate the early- and medium-term outcomes of using double fenestrated physician-modified endovascular grafts (PMEGs) for total endovascular aortic arch repair. The present single-center retrospective analysis of prospectively collected data included 50 patients from January 2017 through October 2019, who had undergone thoracic end...
Acquisition of multidrug-resistant bacteria and encoding genes among French pilgrims during the 2017 and 2018 Hajj.
...The objective of this study is to determine the acquisition of multidrug-resistant (MDR) bacteria and antibiotic resistance-encoding genes by French Hajj pilgrims and associated risk factors. Pilgrims traveling during the 2017 and 2018 Hajj were recruited. All pilgrims underwent two successive systematic nasopharyngeal and rectal swabs, pre- and po...

Behavior of CAD/CAM ceramic veneers under stress: A 3D holographic study
ObjectivesCeramic veneers restorations may undergo damages, such as cracks, fractures, or debonding. Full-field measurements must be carried out in order to visualize and analyze the strain fields. This paper demonstrates that digital holography permits to investigate the mechanical behavior under stress of a natural incisor and a natural incisor r...
Origin of the synergistic effect between TiO2 crystalline phases in the Ni/TiO2-catalyzed CO2 methanation reaction
...
The catalytic performances of TiO2-supported Ni catalysts for the methanation of CO2 have been investigated using different crystalline phases of TiO2 (rutile and anatase). The catalytic activity of Ni depends appreciably on the nature of the support. The rate for CO2 hydrogenation decreases in the order of 10Ni/TiO2-rutile ≫ 10Ni/TiO2-anatase. The...
Tuning the functional properties of lignocellulosic films by controlling the molecular and supramolecular structure of l...
...
This study investigated the relationships between lignin molecular and supramolecular structures and their functional properties within cellulose-based solid matrix, used as a model biodegradable polymer carrier. Two types of derivatives corresponding to distinct structuration levels were prepared from a single technical lignin sample (PB1000): phe...
Identification, molecular and biological characterization of two novel secovirids in wild grass species in Belgium
High throughput sequencing was performed on virion-associated nucleic acids (VANA) from a pool of fifty asymptomatic rough bluegrasses (Poa trivialis L.) collected in a Belgian grazed pasture. Bioinformatics analyses produced some contigs presenting similarities with secovirid genomes, in particular nepoviruses and waikaviruses. Three distinct posi...
