Epitaxial Growth and Design of Nanowires and Complex Nanostructures

Popular Abstract in Swedish Denna avhandling behandlar epitaxiell växt av nanotrådar i III-V halvledarmaterial, i vilken guldpartiklar använts som frö, samt design av tredimensionella mer avancerade förgrenade strukturer baserade på dessa trådar. Växten utfördes via så kallad ?MetallOrganic Vapour Phase Epitaxy? (MOVPE), i vilken prekursormolekylerna till halvledarmaterialens komponenter tillförs This thesis describes the epitaxial growth of III-V semiconductor nanowires using Au seed particles, and the design of more complex three-dimensional branched structures from these wires. Growth was performed by metallorganic vapour phase epitaxy, in which precursor molecules for the semiconductor material components are introduced in a low-pressure vapour. Nanowires grow epitaxially (with control

When Logics Collide: Learning under Organizational Hypocrisy

Most conceptualisations of organizational learning are generally underpinned by some notion of unitarism. Theories typically assume shared visions, values, conceptions or identities. The paper, however, considers the dilemmas faced in organizations where identities and visions are not shared, and where conceptions and ideologies are diverse and possibly in conflict. Such organizations, called here

Bomb-pulse 14C analysis combined with 13C and 15N measurements in blood serum from residents of Malmö, Sweden

The 14C content of 60 human blood serum samples from residents of Malmö (Sweden) in 1978, obtained from a biobank, has been measured to estimate the accuracy of 14C bomb-pulse dating. The difference between the date estimated by using the Calibomb software and sampling date varied between -3±0.4 and +0.2±0.5 years. The average age deviation of all samples was -1.5±0.7 years, with the delay between

Protein dynamics: aggregation and mechanical unfolding

The subject of this thesis is protein dynamics. Papers I--IV and VI study either of two different processes: mechanical unfolding and aggregation. Paper V presents a computationally efficient all-atom model for proteins, variants of which are used to perform Monte Carlo simulations in the other papers. Mechanical unfolding experiments probe properties of proteins at the single molecule level. The

Self-reported mindfulness mediates the relation between meditation experience and psychological well-being

A well established notion in Buddhist literature is that meditation practice improves the ability to be mindful in daily life which in turn promotes psychological wellbeing. In order to test this hypothesis the relations between meditation experience, five mindfulness facets and psychological well-being were studied in a sample consisting of Buddhist meditators, Western mindfulness meditators and
