2. 1. Computational homogenisation and solution strategies for phase-field fracture

   Author : Ritukesh Bharali; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; irreversibility; multi-scale; slack variable; micromorphic; quasi-brittle; brittle; phase-field fracture; homogenisation;

   Abstract : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. READ MORE

4. 2. Mechanical Pulp Based Nano-ligno-cellulose : Production, Characterisation and their Effect on Paper Properties

   Author : Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Kristin Syverud; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose NLC ; handsheets; strength properties; crill;

   Abstract : Almost all research on biorefinery concepts are based on chemical pulping processes and ways of utilising lignin, hemicelluloses and extractives as well as a part of the remaining cellulose for production of nano materials in order to create more valuable products than today. Within the Forest as a Resource (FORE) research program at FSCN we are utilising the whole chain of unit processes from forestry to final products as paper and board, where the pulping process research focus on high yield process as TMP and CTMP.

5. 3. The Physicochemical and Sensory Properties of Fruit and Vegetable Fibre Suspensions - The Effect of Fibre Processing and its Addition to Low-Fat Sausages

   Author : Hanna Bengtsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; carrot; apple; potato pulp; tomato; sensory perception; low-fat sausages; texture; heat treatment; homogenisation; Dietary fibre suspensions;

   Abstract : Due to the health effects of dietary fibre, as well as its water-holding capacity (WHC), food products are commonly fortified with fibre-rich sources. However, to be able to design food products with specific textural properties that also appeal to the consumer, it is important to understand and to characterise the physicochemical and chemical properties of the fibre.

6. 4. Mircostructure and rheological properties of concentrated tomato suspensions during processing

   Author : Elena Bayod; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheology; microstructure; morphology; flocs; tomato paste; ketchup; fibre suspensions; viscoelastic properties; particle size distribution; time dependency; network; yield stress; wall slip; Mooney; Cox-Merz rule; Tikhonov; tube viscometer; rotational viscometer; homogenisation; shearing;

   Abstract : Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural and rheological properties of the material.

7. 5. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams

   Author : Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Mark Martinez; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose; microfibrillated cellulose; nanofibrillated cellulose; paper; strength properties; crill; TEMPO; nanographite NG ; composite films;

   Abstract : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.
