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

    Master-uppsats, KTH/Funktionella material, FNM

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

    Sammanfattning : 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. LÄS MER

  3. 7. Zinc abundances of stars in the Milky Way

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Max Haase; [2015]
    Nyckelord :zinc abundances; Physics and Astronomy;

    Sammanfattning : In this work we study the spectra of 423 stars in the Milky Way disk in order to determine their zinc abundances. The methodology to determine elemental abundances consists of synthesising sets of spectra with varying zinc abundances and comparing them with the observed spectra to find the best fit. LÄS MER

  4. 8. Printed Schottky Diodes based upon Zinc Oxide Materials

    Master-uppsats, Fysik och elektroteknik; Tekniska högskolan

    Författare :Emma Persson; [2013]
    Nyckelord :Schottky diode; semiconductor; rectifier; diode bridge; printed electronics; Teknisk fysik; Teknisk fysik;

    Sammanfattning : The aim of this master thesis was to develop a process for fabricating Schottky diodes, using techniques that are suitable for cheap large volume mass production e.g. printing, with tetrapod structured ZnO as the semiconductor. LÄS MER

  5. 9. Role of the photosystem II-associated CAH3 in the oxygen evolving machinery in Chlamydomonas reinhardtii

    Master-uppsats, Institutionen för fysiologisk botanik; Umeå Plant Science Centre (UPSC)

    Författare :Umut Rende; [2012]
    Nyckelord :;

    Sammanfattning : One of the most abundant proteins on the Earth is ribulose-1,5-biphosphate carboxylase/oxygenase (RUBISCO). RUBISCO is a CO2 fixing enzyme in oxygenic photosynthetic organisms that it has low affinity for CO2. When CO2 is the limiting factor in the environment, RUBISCO works inefficiently due to its oxygenase activity. LÄS MER

  7. 10. Water purification capacity of natural mixed clays from Malawi

    L3-uppsats, SLU/Dept. of Soil and Environment

    Författare :Anna Hernell; [2009]
    Nyckelord :chromium III ; lead II ; zinc II ; copper II ; cadmium II ; adsorption; surface complex; natural clays; water treatment;

    Sammanfattning : Lack of fresh and clean drinking water is a problematic issue for many people worldwide. The water quality in some streams in Malawi, situated in south east Africa, has recently been investigated. The study shows that the concentration of several heavy metals exceeds the guideline values in drinking water set by WHO. LÄS MER
