Novel biorenewable composite of wood polysaccharide and polylactic acid for three dimensional printing, Wenyang Xu et al , Carbohydrate Polymers , Vol.187 . Hemicelluloses, the second most abundant polysaccharide right after cellulose, are in practice still treated as a side-stream in biomass processing industries. In the present study, we report an approach to use a wood-derived and side-stream biopolymer, spruce wood hemicellulose (galactoglucomannan, GGM) to partially replace the synthetic PLA as feedstock material in 3D printing. Combining with 3D printing technique, the biocompatible and biodegradable feature of spruce wood hemicellulose into the composite scaffolds would potentially boost this new composite material in various biomedical applications such as tissue engineering and drug-eluting scaffolds. Design and preparation of metal-organic framework papers with enhanced mechanical properties and good antibacterial capacity, Liwei Qian et al , Carbohydrate Polymers , Vol.192. In this study, a biodegradable paper-based composite with good mechanical and antibacterial properties was obtained by first reinforcing the cotton pulp-based paper with carboxylated cellulose nanofiber (CNF) via the Williamson reaction, followed by in situ generating zeolitic imidazolate framework-67 (ZIF-67) nanoparticles on the surface of the resulting cellulosic material. The mechanical properties and antibacterial activities of the resulting composite were investigated. This biodegradable composite could be potentially used in the field of medical and health security. Converting untreated waste office paper and chitosan into aerogel adsorbent for the removal of heavy metal ions, Zhanying Li et al , Carbohydrate Polymers , Vol.193. The utilization of waste paper, an obsolete recyclable resource, helps to save resources and protect environment. In this paper, an aerogel was prepared to convert the waste paper into a useful material, which was used to adsorb heavy metal ions and handle water pollution. The low cost, environmental friendliness, excellent adsorption capacity and regeneration ability made this novel aerogel a promising adsorbent for heavy metal ions. Microstructural characterization of nanocellulose foams prepared in the presence of cationic surfactants, Marcos Mariano et al , Carbohydrate Polymers , Vol.195. I n this work, we explore the architecture of highly porous foams based on cellulose nanofibers (CNFs) prepared by using cationic surfactants as modifying agents. A study on the transmission haze and mechanical properties of highly transparent paper with different fiber species, Panpan Zhou et al , Cellulose , Vol.25 (3). Transparent paper with high transmission haze has garnered great attention due to its potential applications in light management of optoelectronics as a bulk optical material. Herein, we investigated the transmission haze and mechanical properties of transparent paper with different fibre species. This work sheds light on the preparation of highly transparent and strong paper with excellent light scattering behaviour for manipulating light behaviour of optoelectronics as a bulk optical material. Regenerated cellulose from N -methylmorpholine N -oxide solutions as a coating agent for paper materials, Marta Krysztof et al , Cellulose , online. The objective of the presented research was to determine the influence of cellulose coating, obtained from the cellulose solution in N -Methylmorpholine N -oxide (NMMO), on the structural and mechanical properties of paper. The effect of heating time of paper samples coated with cellulose dissolved in NMMO was also investigated.
