  1. 1. Auditory organotypic cultures and progenitor cell implantation

    Författare :Andreas Kaiser; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : According to the WHO, about 5 % of the world’s population suffers from disabling hearing loss. In people above the age of 65 the number is more than 30 %. Common effects of this condition are poor speech discrimination and impaired communication abilities. Patient surveys show that hearing loss often leads to a diminished quality of life. LÄS MER

  3. 2. Magnetotransport Studies of Mn Ion-Implanted Nanowires

    Författare :Waldomiro Paschoal; Linnaeus University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hopping conduction; ferromagnetism; ion-implantation; Nanowire; GaMnAs; magnetoresistance; Fysicumarkivet A:2014:Paschoal;

    Sammanfattning : This thesis focuses on the magnetotransport properties of highly Mn-doped crystalline GaAs nanowires. The GaAs nanowires were first grown by metal-organic vapor phase epitaxy from gold seed particles, and subsequently implanted with Mn ions under varying conditions, e.g., ion fluence and acceleration voltage.

    Sammanfattning : The primary focus of this thesis is to study the effect of doping on magnetic properties in amorphous Fe100−xZrx alloys. Samples with compositions of x = 7,11.6 and 12 at.% were implanted with different concentrations of H. LÄS MER

  5. 4. Molecular and functional studies on human embryo implantation : targets for infertility and fertility regulation

    Författare :Nageswara Rao Boggavarapu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: An estimated one in four couples globally suffers from infertility or fertility related issues and rate of global infertility is about 10-15%. Despite the best optimization of assisted reproductive technique the pregnancy rate is not more than 30%. LÄS MER

  7. 5. Stability of point defects in silicon induced by high energy low dose ion implantation

    Författare :Lalita Josyula; KTH; []
    Nyckelord :;

    Sammanfattning : Ion implantation is a key' process for the introduction ofdopants in semiconductor technology. It involves bombarding thesubstrate material with energetic ions. LÄS MER
