    Ce stage a pour but de développer puis d’optimiser une méthode de mesure in-situ permettant de relever la température à l’interface de soudage pendant l’assemblage de papiers/cartons. Elle présente un fort potentiel en vue de mieux comprendre le soudage US des papiers/cartons, notamment concernant l’identification des contributions du procédé et du matériau à la formation des joints soudés. // The objective is to develop and optimize an in-situ temperature monitoring which can record the temperature at the welding interface during the US welding of papers. Such a method could be highly valuable to understand the phenomena intervening when welding papers. In particular, it could lead to a better understanding regarding what are the respective contributions of process inputs and material properties in the establishment of the welded joints.

    In the framework of a collaborative project with a European industrial partner producing high technicity papers, the LGP2 laboratory (Laboratory of Pulp and Paper Science and Graphic Arts, UMR CNRS-Grenoble INP 5518) offers a 6-month internship forM2 students. The objective of this project is to propose solutions that can be transferred on an industrial scale in the short term, to a company seeking to improve the end-use properties of the materials produced by committing to an eco-design approach. This study is part of a larger project and follows a previous collaboration with the same partners. Despite positive results and patent filing, there are still questions and challenges to overcome for the up-scaling of these results on production paper machine. It will build on the results already obtained, with the objective to optimize and transfer the most promising results to a pilot and industrial scale.

    The objective of this study is to propose an innovative low -energy and environmentallyfriendly combinative process for the production of M/NFC from bleached Eucalyptus bark(EB) and Beechwood (BW). The main originality of the project is to compare producedM/NFCswith M/NFCs already produced from unbleached EB and BW. The main goal is to study the effect of lignin on the properties of M/NFCs. Applications in the fields of packaging (films or nanopapers) and wood particleboard (tannins-based adhesives) will be considered in the project.

    Currently, research is oriented toward the use of microfibrillated cellulose (MFC) as a replacement for fossil-fuel based materials, e.g., in composites, coatings and packaging materials.The typical raw material is a chemically delignified, bleached cellulose pulp, although more and more research is oriented towards the study of the potential use of unbleached pulp. Indeed, several efforts have been made to find cost-effective methods and raw materials to produce MFC in a more environmentally friendly way. Actually, the extraction of cellulose nanofibrils containing lignin (LCMF) makes possible the use of a cheaper raw material while eliminating the bleaching stage. In fact, the effect of the presence of lignin is still debated in the scientific literature...
