2. Micro-mechanically based modeling of mechano-sorptive creep in paper
Abstract : The creep of paper is accelerated by moisture content changes. This acceleration is known as mechano-sorptive creep, which is also found in wood and some other materials. Mechano-sorptive creep has been known for several decades but it is still not well understood, and there is no generally accepted model explaining the effect. READ MORE

3. Mechano-sorptive Creep in Wood - Experimental Studies of the Influence of Material Properties
Abstract : Mechano-sorptive creep deformations appear when wood is loaded under varying moisture conditions. These creep deformations are known to be larger than the creep deformations under constant humidity conditions. The present thesis deals with mechano-sorptive creep in Norway spruce wood. READ MORE

4. Strategies for improving kraftliner pulp properties
Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE

5. The Use of Lignin Derivatives to Improve Selected Paper Properties
Abstract : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. READ MORE
