Application of nanocomposite cellulose fibers with luminescent properties to paper functionalization, A. Erdman, P. Kulpinski, K. Olejnik, Cellulose , Vol.23, No.3. Cellulose fibres modified with luminescent inorganic compound were obtained by using N- methylmorpholine-N-oxide as a direct solvent. The fibres were cut and introduced to the unrefined and refined paper pulp samples. Results showed that cellulose man-made fibres with luminescent properties express similar properties to natural cellulose fibres (e.g. external fibrillation and bonding properties) which are useful for the purpose of secure paper production. Cellulose man-made fibres introduced to the paper do not have any disadvantageous impact on paper properties. Synthesis of Nanosilver Particles in the Texture of Bank Notes to Produce Antibacterial Effect, Mohammad Hossein, Asadi Lari, Vahid Esmaili, Amir Hossein Kimiaghalam, Emadaldin Sharifaskari, International Journal of Nanoscience , Online. Silver particles show antibacterial and antiseptic properties at the nanoscale. Such properties result from an alteration in the binding capacity of silver atoms in bits of less than 6.5nm which enables them to kill harmful organisms. Silver nanoparticles are now the most broadly used agents in the area of nanotechnology after carbon nanotubes. Given that currency bills are one of the major sources of bacterial dissemination and their contamination has recently been nominated as a critical factor in gastrointestinal infections and possibly colon cancers, here we propose a new method for producing antibacterial bank notes by using silver nanoparticles. Green coconut shell extract and boric acid: new formulation for making thermally stable cellulosic paper, Santanu Basak, Prashant G Patil, Abdul J Shaikh, Kartick K Samanta, Journal of Chemical Technology and Biotechnology , Vol.91, No.11. For the first time, green coconut shell extract (GCSE) has been employed along with boric acid as a novel fire retardant agent to be applied to cellulosic paper. GCSE can be considered a condensed phase based flame retardant agent as it contains silicate, other metals like potassium, zinc, copper and magnesium in the form of metallic salts, oxides etc. When GCSE was applied on paper, the combined synergistic action of all these metal salts and oxides catalyze dehydration of the treated paper and also increased char formation. PACKAGING TECHNOLOGY Morphological, physical, antimicrobial and release properties of ZnO nanoparticles- loaded bacterial cellulose films, Fereshteh Shahmohammadi Jebel, Hadi Almasi, Carbohydrate Polymers , Vol.149. Bacterial cellulose (BC) monolayer and multilayer films, incorporating 5wt.% ZnO nanoparticles (NPs) were produced. Antibacterial activity of ZnO-BC films against S. aureus was more than E. coli . Results suggest that ZnO-BC films may be used as controlled release antimicrobial food active packaging. Active bio-based food-packaging: Diffusion and release of active substances through and from cellulose nanofiber coating toward food-packaging design, Nathalie Lavoine, Valérie Guillard, Isabelle Desloges, Nathalie Gontard, Julien Bras, Carbohydrate Polymers , Vol.149. Cellulose nanofibres (CNFs) were investigated for the elaboration of new functional food-packaging materials. Their nanoporous network was especially of interest for controlling the release of active species. This work aims to model CNF-coated paper substrates as controlled release system for food-packaging using release data obtained for two model molecules, namely caffeine and chlorhexidine digluconate.
