1. Chemical modification of cellulose-new possibilities of some classical routes
Abstract : Owning to its unique structure, along with the inexhaustible renewability, cellulose has been a subject of scientific and commercial interest for over 150 years. However, given attractive structural properties, such as stiffness, hydrophilicity, stereoregularity, potential for chemical modifications and ability to form superstructures, utilization of this biopolymer is far below its potential.

2. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard
Abstract : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. READ MORE

3. Chemical Functionalization and Characterization of Cellulosic Materials
Abstract : Polysaccharides are the most abundant biopolymers produced in nature and belong, together with proteins and nucleic acids, to the main components of life. Polysaccharides are polyhydroxylic polymers that can be functionalized by a wide selection of chemical reactions, and modifications of these biopolymers are applicable in the development of new materials.

5. Discovery and applications of family AA9 lytic polysaccharide monooxygenases
Abstract : Auxililary activity family 9 lytic polysaccharide monooxygenases (abbreviated as AA9s or LPMO9s) are fungal mono-copper enzymes capable of oxidatively cleaving various plant cell wall oligo- and/or polysaccharides. LPMO9s are key components of lignocellulolytic enzyme cocktails used in today’s biorefineries to break down biomass into fermentable sugars. READ MORE
