16. Microfibrillated cellulose: Energy-efficient preparation techniques and applications in paper
Abstract : This work describes three alternative processes for producing microfibrillated cellulose (MFC; also referred to as cellulose nanofibrils, CNF) in which bleached pulp fibres are first pretreated and then homogenized using a high-pressure homogenizer. In one process, fibre cell wall delamination was facilitated by a combined enzymatic and mechanical pretreatment. READ MORE

18. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide
Abstract : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. READ MORE

19. Structural Studies and Modelling of Oxygen Transport in Barrier Materials for Food Packaging
Abstract : The requirements of food packages are to ensure food safety and quality, to minimize spoilage, and to provide an easy way to store and handle food. To meet these demands for fibre-based food packages, barrier coatings are generally used to regulate the amount of gases entering a package, as some gases are detrimental to food quality. READ MORE

20. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging
Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE
