  1. 6. Evaluation of Zinc Oxide Nano-Microtetrapods for Biomolecule Sensing Applications

    University essay from KTH/Funktionella material, FNM

    Author : Wei Zhao; [2015]
    Keywords : zinc oxide tetrapods; nano-microstructure; glucose oxidase; glucose sensor;

    Abstract : Zinc oxide (ZnO) is a well-known II-VI semiconductor material that has gained renewed interest in the past decade due to the developments of growth technologies and the availability of high-quality ZnO bulk single crystals. Owing to a wide direct band gap (3. READ MORE

  3. 7. Carboxylated Cellulose Nanocrystals Extraction from Kraft Pulp Using Ammonium Persulfate as Low Cost Source & Sustainable Method for High Quality Flexible Packaging Bio-coating

    University essay from Lunds universitet/Förpackningslogistik

    Author : Gerald Perry Estavillo Marin; [2015]
    Keywords : affordable CNC extraction; high quality CNC; sustainable packaging; FT-IR; TEM; XRD; contact angle; transparency; haze; optical properties; food packaging; bio-packaging; bio-coating; plastics; PET film; polyethylene terephthalate; Kraft CNC; Kraft pulp; cotton CNC; oxygen barrier; nanocellulose crystals; ammonium persulfate; CNCs; cellulose nanocrystals; Chemistry;

    Abstract : One of the leading challenges presented in 21st century for packaging industry is to address the growing environmental problems related to non-renewable flexible packaging. This leads to new growing interest in bio-based materials, among them cellulose nanocrystals (CNCs), which have already shown good performance in improving anti-fog and oxygen & water vapor barrier properties when applied to flexible film.

  4. 8. Region-Based Contrast Transfer Function correction for Electron Microscopy Images

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Yohannes Haileyesus Ayele; [2013]
    Keywords : CTF; MelB; TEM; Fourier Transform FT ; Local averaging Lattice filtering ;

    Abstract : Electron crystallography is one of the methods for determining the structure of membrane proteins. However, the resolution that we get from electron crystallography of membrane proteins is limited by crystal disorder and inaccurate determination of contrast transfer function (CTF) parameters.

  5. 9. Environmental impacts of early metallurgy in Moshyttan : A study of one of Europe's oldest blast furnaces, using three lakes records in Nora bergslag

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Erik Myrstener; [2013]
    Keywords : Diatoms; Biogenic silica; Geochemistry; Pre-industrial metallurgy; Environmental effects;

    Abstract : The aim of this study was to assess the environmental effects of Moshyttan, one of the earliest known blast furnaces in Europe (ca. 11th century). The study was based on the analysis of three lake records in the immediate surroundings of the smelter. Fickeln lies directly downstream and is the main recipient of waterborne pollution. READ MORE

  6. 10. Screening of blood and mucus parameters towards breeding for resistance to salmon louse (lepeophtheirus salmonis) in atlantic salmon

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Das Amit; [2012]
    Keywords : Sea lice; parasite resistance; disease resistance; genetic variation; Atlantic salmon; Rainbow trout; biological markers;

    Abstract : Over the last three decades salmon farmers have experienced serious economic hardships due to losses caused by sea lice (Lepeophtheirus salmonis) infestations. In the absence of an effective vaccine, inefficiency of biological control methods and growing concerns over the usage of chemical treatments, there is a quest for alternative strategies to combat this problem.
