2. 1. Quantitative microscopy of coating uniformity

   Author : Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

   Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

4. 2. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

   Author : Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

   Abstract : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. READ MORE

5. 3. Large-Scale Graphene Production for Environmentally Friendly and Low-Cost Energy Storage : Production, Coating, and Applications

   Author : Nicklas Blomquist; Håkan Olin; Renyun Zhang; Christina Dahlström; Patrik Johansson; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Energy storage; Supercapacitors; EDLC;

   Abstract : There is great demand for energy-efficient, environmentally sustainable, and cost-effective electrical energy storage devices. One important aspect of this demand is the need for automotive electrification to achieve more energy-efficient transportation at a reasonable cost, thus supporting a fossil-fuel free society.

6. 4. Characterisation of Time-dependent Statistical Failure of Fibre Networks : Applications for Light-weight Structural Composites

   Author : Amanda Mattsson; Tetsu Uesaka; Christina Dahlström; Sören Östlund; Mittuniversitetet; []
   Keywords : ;

   Abstract : The future of a sustainable society requires that materials not only be renewable, but also leave as small a carbon foot-printin the environment as possible. One such product is light-weight composite material for transportation packages. Cellulose fibres have been and will continue to be ideal for this purpose. READ MORE
