   Abstract : 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.

4. 12. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface

   Author : Mohd Farhan Ansari; Lars Berglund; Jean-Francois Gerard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; cellulose nanofibrils; hygromechanical properties; network structure; thermoset; polymer matrix composites; natural fiber composites; pulp fiber; strain hardening; humidity; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.

5. 13. Non-linear mechanics of nanocellulose foams

   Author : Prashanth Srinivasa; Artem Kulachenko; Kristofer Gamstedt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : There has been a growing interest in nano-fibrillar cellulose (NFC), which has been fuelled not merely by the advantages it presents in terms of strength to weight ratio and biodegradability, but also owing to the recent advances in production techniques. NFC foam is essentially a hierarchical structure, wherein nanofibrils account for the smallest scale, with the pores/cell walls forming the meso scale. READ MORE

6. 14. Surface Modification of Nanocellulose towards Composite Applications

   Author : Assya Boujemaoui; Anna Carlmark Malkoch; Eva Malmström Jonsson; Julien Bras; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; surface modification; functionalization; composites; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Nanocelluloses have attracted great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of this work was to investigate new strategies for surface modification and functionalization of nanocelluloses and their subsequent incorporation in polymer-host matrices. READ MORE

7. 15. The synthesis of dendritic hydrogels and inorganic nanoparticles and their application as antibacterial and imaging materials

   Author : Yanmiao Fan; Michael Malkoch; Annelie Brauner; Mauri Kostiainen; KTH; []
   Keywords : antibacterial hydrogels; dendritic polymers; dendrimers; silicon nanoparticles; cellulose nanofibrils; drug-resistant bacteria; wound dressings; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : AbstractThe overuse and misuse of conventional antibiotics has caused increased prevalence of drug-resistant bacteria, the infections of which cause high mortality and economic losses per year. It is therefore crucial to develop new technologies and treatments for infections caused by drug-resistant bacteria. READ MORE
