This perspective gives an overview of recent progress in thefield of photocured polymer composites based on variousforms of nanocelluloses, with a focus on cellulose nanofibrils. The manufacturing processes and performances of these nanocellulosecomposites ...
Nous ne vivons plus au gré des saisons, nous vivons au gré du pétrole. L’énoncé théorique Transformer plutôt que démolir. Le soleil à la place du pétrole s’est focalisé sur l’énergie solaire et la nécessité de réhabiliter le parc bâti datant du XXe siècle. ...
The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
Additive manufacturing offers the opportunity to produce complex geometries from novel alloys with improved properties. Adapting conventional alloys to the process-specific properties can facilitate rapid implementation of these materials in industrial pra ...
This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...
The purpose of this project is to fabricate a mould etched by KOH for PDC casting and produce the fist PDC using this method. Casting for PDC is a known process, it has been done with PDMS moulds created from Si masters. Si moulds have also been fabricated ...
For dielectric elastomer actuators (DEAs) to find more widespread adoption in commercial products, a better understanding of their durability is needed. By determining the different mechanisms contributing to ageing and breakdown in DEAs, new methods for i ...
This is the first account of the history of modelling dendritic and cellular solidification. While Part I reviewed the progress up to the year 2000 [Kurz W, Fisher DJ, Trivedi R. Progress in modelling solidification microstructures in metals and alloys: de ...
When developing or designing biomimetic robotic fingers with rigid and soft components and integrated sensors, fabrication is often a bottle-neck when assembling and casting processing techniques are used. This study introduces a thermoplastic multi-materi ...
