1. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. LÄS MER
2. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process
Master-uppsats, Karlstads universitetSammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

3. Tomography-based Micromechanical Analysis of Novel Composite Material
Master-uppsats, KTH/HållfasthetsläraSammanfattning : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. LÄS MER
4. Undersökning av mekaniska egenskaper hos sandwichelement av core-materialet Greenwood och ytskikt av papp : Styvhet, bärförmåga samt elementens beteenden vid belastning för olika tjocklekar på ytskikten
Uppsats för yrkesexamina på grundnivå, Karlstads universitetSammanfattning : Byggbranschens utsläpp av växthusgaser utgör en stor andel av Sveriges totala utsläpp. För att minska de byggrelaterade utsläppen är det på många fronter som byggbranschen behöver förändras och effektiviseras. LÄS MER
5. Optimalt körsätt för pluggskruv : Identifiering av orsaker till stopp i pluggskruv samt framtagning av parametrar för optimalt körsätt
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : Hallsta Paper Mill, which is a part of Holmen Paper, uses the Thermo Mechanical Pulping process to produce paper pulp. One of their process steps is a plug screw feeder that transport and compresses chips. LÄS MER
