5. 29. Cationic Dendritic Polymers and Their Hybridization with Cellulose Nanofibrils

   Författare :Faridah Namata; Michael Malkoch; Lars Wågberg; Francisco Javier de la Mata de la Mata; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dendritic polymers; antibacterial materials; carboxylated cellulose nanofibrils; hybrid hydrogels; bis-MPA polyester dendrimers; dendritic linear dendritic; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Antimicrobial resistance (AMR) is one of the major global threats to thehealth of humans, animals, plants and ecosystems. AMR arises whenbacteria, viruses, fungi, and parasites undergo changes over time; makingmedicines such as antibiotics, antivirals, antifungals and antiparasiticineffective at treating infections.

7. 30. Exploring the Wood Adhesive Performance of Wheat Gluten

   Författare :Petra Nordqvist; Eva Malmström Jonsson; Mats Johansson; Bo Mattiasson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant protein; wood adhesive; mechanical properties; wheat gluten; soy protein isolate; gliadin; glutenin; adhesion; hydrolysis; heat treatment; AFM;

   Sammanfattning : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.
