Polymères hautes performancesIndex. décimale : 668.4 Plastiques, vinyles Résumé : When printing high-performance polymers such as PEEK, stresses occur in the component due to the relatively high printing temperature and the changes in the material structure. These stresses can lead to microcracking, warping, cracking and ultimately to component failure. In the Smart Printbed project, a system was developed to minimize these influences and also save electrical energy. Note de contenu : - The zone heating system supplies energy only where it is needed
- Design of the smart print bed
- Optimal thermal management requires perfect interaction
- Fig. 1 : The smart printbed can heat, cool and measure temperature. The schematic sketch of the print bed shows the structure, which consists of 25 individual Peltier elements
- Fig. 2 : It all depends on the correct wiring : Only with a bridge circuit can the Peltier elements assume all three operating states (heating, cooling and measuring)En ligne : https://drive.google.com/file/d/1f_paUzdVVUz1Ef5td0LM7XSuc9aDgNVC/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=35741

Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Nanotechnology is recognised as one of the most important new technologies of the 21m century, and there is clearly a public expectation that it will figure prominently in the future economic landscape. Nanotechnology promises new materials for industrial applications with new or enhanced physicochemical properties that are different from these of their micron-sized counterparts. Moreover, nanotechnology is focused on the new era of manufacturing societies based on knowledge.
As nanotechnology enters industrial applications, the potential exposure of humans and the environment to these materials (nanoparticles in particular) is unavoidable. As nanoparticles go through their life-cycle (from development, to manufacture, to consumer usage, to final disposal) different human groups (workers, bystanders, users), animal species (e.g. worm, fish or human through secondary exposure) and natural environments (air, soil, sediment, water) will be exposed to them. A growing body of evidence has shown a range of toxic effects from engineered nanomaterials (nm), suggesting that even their low mass exposure will result in a risk to human health or the environment. Living bodies are net prepared for the massive appearance of nanoparticles and their derivative effects. Therefore, it is clear that there is a need for a better understanding of the relationship between nm's properties and the adverse responses they can potentially cause in the short term. Nowadays, governments are tackling industrial concerns around nm use by applying restrictive policies. At present, long-term studies are not an option and it is compulsory to produce nm with a reduction of the collateral adverse effects. Reducing the potential risks of nanomaterials represents firstly a challenge to the companies and secondly a tremendous business opportunity for companies to gain an advantage over competitors.Note de contenu : - IS THERE A WAY TO OBTAIN BENEFITS FROM SAFE-BY DESIGN MN'S ? : AD particles technology
