NANOMECHANICAL TESTING OF DIATOMS
Bjørnøy, Sindre Hove (Master thesis, 2012)A test scheme to test micro-beams from diatom frustule has been developed. The method is capable of testing both complete beams and beams made from the individual layers of the frustule. The biosilica is shown to be a very ... -
NANOMECHANICAL TESTING OF ICCGHAZ OF ARCTIC STEEL
Kvaal, Aksel Louis Legouy (Master thesis, 2015)An ever increasing demand for energy is forcing the oil industry to push technology forward, as new oil rich fields are discovered further North. The Arctic offers a harsh, cold climate, leading to new challenges within ... -
Nanomechanical testing of in situ hydrogen charged high strength steel
Kuipers, Jonatan (Master thesis, 2013)The effect of finely dispersed titanium carbides on the nanomechanical behavior of high strength steel in the presence of hydrogen has been investigated. Nano sized pillars have been milled from steel samples using a Focused ... -
Nanomekanisk prøving av stål: Er mindre alltid sterkere?
Haugen, Veronica Gausel (Master thesis, 2012)Gjennom dette arbeidet, er nanomekaniske kompresjonsegenskaper undersøkt for tre forskjellige materialer: To stål legeringer og et renjern. Pillarer av varierende størrelse, fra diameter 100nm til 2um, er fabrikkert ved ... -
Natural Superhydrophobic Surfaces: Nanostructures and Wetting States on Collembola Cuticles
Gundersen, Håkon (Doctoral theses at NTNU;2016:368, Doctoral thesis, 2016)Highly water repellent surfaces, known as superhydrophobic surfaces, have a range of potential applications including self-cleaning, drag reduction and air-retention. The first studies of the superhydrophobic effect was ... -
Optimization of nozzles and branches welded to pressure vessels or pipes used in chemical processing plants
Hålien, Werner (Master thesis, 2015)The master project was ready to start in mid-February, so some time was lost in the beginning. The company, Cambi prepared a workstation for me in their office in Asker. The work started with reading about the problem and ... -
Seasonal change in the wetting characteristics of the cuticle of the Collembola Cryptopygus clavatus (Schött, 1893)
Gundersen, Håkon A Holm; Thaulow, Christian; Leinaas, Hans Petter (Journal article; Peer reviewed, 2015)The littoral Collembola Cryptopygus clavatus spends the summer submerged, grazing on algae under water, and the winter on dry land. The cuticles of Collembola are, in general, highly water repellent, often superhydrophobic; ... -
SMALL-SCALE FRACTURE AND ARREST TESTING OF IRON AT LOW TEMPERATURES
Snartland, Brage Dahl (Doctoral theses at NTNU;2018:244, Doctoral thesis, 2018)The industrial activity in the Arctic is expanding. An ever-increasing demand for energy is forcing the production of oil further north, where accidents may have severe ecological ramifications. Rough climate conditions ... -
Surface structure and wetting characteristics of Collembola cuticles
Gundersen, Håkon A Holm; Leinaas, Hans Petter; Thaulow, Christian (Journal article; Peer reviewed, 2014)The cuticles of the arthropods Collembola (springtails) are known to be superhydrophobic, displaying such properties as water-repellence and plastron formation; overhanging surface structures have been suggested as the ... -
To Give Or Not To Give: A Step Towards Addressing The Heart Of Innovative Climates
Livesay, Zackary Steven (Master thesis, 2013)Innovative climates are largely affected by the relationships between the individualsinvolved. This thesis addresses the topic of trying to improve the quality ofrelationships by giving engineers some tools and principles ... -
Valg av konstruksjonsklasser på grunnlag av constraintberegninger
Fossum, Martin (Master thesis, 2012)En stor del av fremtidens gassreserver ligger i arktiske strøk og på grunn av det harde klimaet og de lave temperaturene er det knyttet store utfordringer til utbygging i disse områdene. Robuste materialvalg er her viktig, ... -
Wetting Properties of Springtail Cuticles: A Quantitative Analysis
Sandnes, Runar (Master thesis, 2012)With the prospect of producing superhydrophobic and mechanically stable biomimetic surfaces, the water repellent properties of springtail cuticles are investigated quantitatively. The analysis is based on apparent contact ...
