1. 1. Antimicrobial materials from cellulose using environmentally friendly techniques

   Författare :Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

3. 2. Advances in DNA Detection on Paper Chips

   Författare :Yajing Song; Olof Emanuelsson; Mats Nilsson; Aman Russom; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA detection; active filter papers; visualization; throughput; fluorescence; superparamagnetic beads; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Sammanfattning : DNA detection has an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used not only in research laboratories, but also in clinical and forensic practice. LÄS MER

4. 3. Electrochromic Polymer Devices: Active-Matrix Displays and Switchable Polarizers

   Författare :Peter Andersson; Magnus Berggren; Nathaniel Robinson; Per Bröms; Linköpings universitet; []
   Nyckelord :conjugated polymer; PEDOT:PSS; active-matrix; displays; polarizer; polyaniline; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Major efforts have been spent during recent years in worldwide attempts to achieve an electronic paper technology; the common name for novel flexible displays utilizing substrates such as paper, plastics or thin metal sheets. Various kinds of technology are available that potentially will be used for an electronic paper, which differs from each other mainly with respect to the choice of active materials, substrates and manufacturing techniques.

5. 4. Advances in DNA Detection

   Författare :Yajing Song; Olof Emanuelsson; Jonas Tegenfeldt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA detection; active filter paper; visual detection; throughput; fluorescence; superparamagnetic beads; rare DNA; Q-PCR; chemical fragmentation; DNA library preparation; massively parallel sequencing; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Sammanfattning : DNA detection technologies have an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis, food safety evaluation, and environmental monitoring. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used in research laboratories, in clinical and forensic practice. LÄS MER

7. 5. The Friction between Paper Surfaces

   Författare :Niklas Garoff; KTH; []
   Nyckelord :friction; fibers; boundary lubrication; adhesion; capillary condensation; surface forces; chemcial analysis; x-ray photoelectron spectroscopy; atomic force microscope;

   Sammanfattning : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.
