  • Koistinen, Olli-Pekka (Aalto University School of Science, 2019)
    Chemical reactions and other transitions involving rearrangements of atoms can be studied theoretically by analyzing a potential energy surface defined in a high-dimensional space of atom coordinates. Local minimum points of the energy surface correspond ...
  • Ghosh, Dipankar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020)
    Nature has been successful in self-assembling simple building blocks to complex functional architectures and the concept of supramolecular chemistry has enabled chemists to mimic nature's self-assembly principles. The understanding of the assembly/reassembly ...
  • Shahnazaryan, Vanik (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10)
    The physics of light-matter interactions is a rapidly developing interdisciplinary research area, combining methods and phenomena both from condensed matter physics and quantum optics. One of the most common realizations of strong coupling regime implies ...
  • Natugonza, Vianny (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-06-18)
    The advent of ecosystem-based fisheries management (EBFM) in recent years has expanded the scope of fisheries management, where policies are aimed not only at maximizing production (or biological yield) but also maintaining an optimal balance between ...
  • Nyamweya, Chrispine (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-01)
    Lake Victoria is of immense ecological and socio-economic significance for the riparian communities. However, the lake is faced with human induced pressures such as overfishing, introduction of alien species, increased eutrophication and climate change ...
  • Khosa, Rabia Yasmin (2017)
    Silicon is a semiconductor material used in most power devices and the Si metal-oxide-semiconductor field effect transistor (MOSFET) is the key switching device for high power applications. Recently silicon carbide (SiC) MOSFETs have emerged on the ...
  • Mökkönen, Harri (Aalto University, Helsinki;University of Iceland, Reykjavik, 2016)
    A polymer escaping from a confining external potential represents a generic description of long macromolecules crossing an energy barrier. This type of barrier crossing problems are typical in nano- and microscale polymeric systems, where the polymers ...
  • Elm Heintz, Kasper (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-07)
    In the early Universe, most of the cold neutral gas that will later form into individual stars and galaxies is practically invisible to us. These neutral gas reservoirs can, however, be illuminated by bright cosmic lightsources such as gamma-ray bursts ...
  • Kateb, Movaffaq (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-12-12)
    Permalloy Ni80Fe20 at. % (Py) is a well-known ferromagnet utilized in anisotropic magnetoresistance and planar Hall effect sensors as well as magnetic read heads in magnetic memories. These applications rely on the uniaxial magnetic anisotropy in ...
  • Hjörleifsson, Jens Guðmundur (Jens Guðmundur Hjörleifsson, 2018-06-06)
    Protein quaternary structures are fundament for life. Proteins have evolved towards large assemblies of subunits needed for the execution of complex chemistry, for building structural components or for compartmentalization. Most oligomeric enzymes ...
  • Frater, Paul (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-06)
    Age and length (i.e. composition) data are, along with abundance indices, some of the most basic yet informative data collected in fisheries science. Measurements on age and length have been collected since the study of fish and fish stocks began in ...
  • Thorman, Rachel Megan (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10-27)
    Focused electron beam induced deposition (FEBID) is a nanofabrication technique wherein electron-induced reactions are used to deposit pure metals from organometallic precursors under the area of a primary electron beam. It can be used to directly ...
  • T P, Ragesh Kumar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12-15)
    Focused electron beam induced deposition (FEBID) is a direct-write 3D nanofabrication technique, which works on the principle of electron-induced molecular decomposition. In FEBID, a high-energy focused electron beam dissociates the precursor molecules ...
  • Juhl, Michael (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2018-10)
