    Abstract : Många av oss har någon gång blivit tvungna att ta en penicillinkur mot halsfluss eller kanske i samband med någon annan infektion. Oftast har behandlingen varit till stor nytta, och infektioner som förr i tiden kunde leda till döden har varit lätta att behandla med hjälp av antibiotika. READ MORE

  3. 3. Biocomposites Based on Core-Shell Cellulose Nanofibers Preparation, Structure, and Properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kasinee Prakobna; KTH.; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

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

    University dissertation from KTH Royal Institute of Technology

    Author : Mohd Farhan Ansari; KTH.; [2016]
    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. 5. Multifunctional nanostructured Ti-Si-C thin films

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Per Eklund; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Abstract : In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multi¬layers, as well as their electrical, mechanical, and thermal-stability properties.
