  2. 16. An Investigation of Mixed Cellulose Esters and Acyclic Polyacetates: Effects of Side-Chain Lengths and Degrees of Ring-Opening

    Author : Robin Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water interactions; oxygen permeation; storage modulus; ring-opening; water sorption; cellulose esters; side-chains; acyclic cellulose acetate;

    Abstract : Bio-based polymers produced from natural sources are gaining an increased interest as potential replacement for today’s conventional fossil-based plastic polymers. Their use is already wide in many large-scale industrial areas such as healthcare, personal care, and food. READ MORE

  4. 17. Antibacterial materials for wound care applications utilizing antimicrobial peptides

    Author : Edvin Blomstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lyotropic liquid crystals; antibacterial surface; Antimicrobial peptides; Pluronic F-127; hydrogels;

    Abstract : The spread of antibiotic resistance among bacteria has shown that the development of alternative treatments of infections is of vital importance. This thesis has looked at one potential candidate, antimicrobial peptides (AMPs), as an alternative or compliment to traditional antibiotics. READ MORE

  5. 18. A toolbox for improving the processability of composites with a high content of thermomechanical pulp

    Author : Seyedehsan Hosseini; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface.; thermomechanical pulp; magnesium stearate; mechanical properties; composite; molybdenum disulfide; AKD;

    Abstract : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. READ MORE

  6. 19. Cellulose solutions in aqueous hydroxide bases

    Author : Beatrice Swensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; dissolution; NaOH; aqueous; solvent; quaternary ammonium hydroxide;

    Abstract : Cellulose is a renewable and widely available carbohydrate polymer whose utility for mankind only increases as we move towards a circular bioeconomy. Unlike most plastics or metals, it cannot be melted, and therefore, solution processing is important. READ MORE

  7. 20. Chemical Doping of Conjugated Polymers for Thermoelectric Applications

    Author : Mariavittoria Craighero; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; conjugated polymers; solid-state order; organic thermoelectrics; chemical doping;

    Abstract : The ongoing development of interconnected and wearable small devices, which together make up the so-called Internet of Things, is driving a rising need for autonomous and on-site energy supplies. Heat, an abundant and often wasted energy source, can be harnessed through thermoelectric generators that can directly convert heat into electricity. READ MORE
