GdNi is a rare earth intermetallic material that exhibits very interesting magnetic properties. Spontaneous magnetostriction occurs in GdNi at TC, on the order of 8000ppm strain along the c-axis and only until very recently the mechanism causing this giant magnetostriction was not understood. In order to learn more ab…
Fredagen den 22 juli 2011 kl. 15.25 detonerade en sprängladdning i regeringskvarteret i centrala Oslo. Bomben var mycket kraftig – åtta personer dödades, minst 90 skadades och kringliggande byggnader fick omfattande skador. Senare samma eftermiddag klev en man som utgav sig för att vara polis iland på ön Utøya, där de…
This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmiss…

Zuallererst möchte ich mich herzlich bei allen bedanken, die mich bei dieser Arbeit unterstützt haben.Ohne Ihre/ Eure Hilfe wäre diese Arbeit nicht möglich gewesen.Mein besonderer Dank gilt: • Prof. Dr. D. Johrendt für die Aufnahme in seinen Arbeitskreis, die Möglichkeit dieses Thema unter hervorragenden Bedingungen z…
Thermally bonded nonwovens are low-price substitutes for traditional textiles. They\nare used in many areas including filtration, automotive and aerospace industries.\nHence, understanding deformation behaviours of these materials is required to design\nnew products tailored for specific applications in different area…
This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. Triply periodic minimal surfaces (T…
Carbon (C), beryllium (B) and tungsten (W) are potential candidates as Plasma Facing Materials (PFM) for the International Thermonuclear Experimental Reactor (ITER).During operation, co-deposited layers are formed from the eroded PFM, which will grow with time.At Max-Planck Institut für Plasmaphysik, the interaction b…

This dissertation presents research on scanning probe microscopy and spectroscopy of graphene and carbon nanotubes. In total three experiments will be discussed. The first experiment uses a scanning tunneling microscope (STM) to study the topographic and spectroscopic properties of graphene on hexagonal boron nitride…
The application of techniques from nonlinear analysis to materials science has seen great developments in the recent years and it has really been a driving force for substantial mathematical research in the area of partial differential equations and the multi-dimensional calculus of variations. This thesis has been mo…
Covalent Organic Frameworks (COFs) are a novel class of highly stable, purely organic crystalline frameworks made of molecular building blocks. For example, the condensation of boronic acids with appropriate polyols in principle allows the design of precisely controllable structures since their chemical and physical p…
As it becomes more important to replace fossil fuels with alternative fuels, biofuels like ethanol are becoming more commercially used. The increased use of ethanol brings good influences such as lower impact on the environment. However, the use of ethanol can also bring negative effects regarding corrosion of metals.…
The Selective Catalytic Reduction (SCR) of NOx by NH3 is one of the most effective NOx reduction processes. It is widely employed in units of industrial scale where vanadium based metal oxides, VOx, act as catalysts. The SCR reaction has been studied experimentally in great detail. However, details of the reaction mec…
The suture is one of the most commonly used medical devices, consisting of a fiber, a surgical needle and the packaging in which it is stored. The fiber itself remains after implantation for a defined time and is responsible for the approximation of the wound during the healing process. The needle merely serves to aid…
La conception de nouveaux materiaux pour les piles a combustible a oxydes solides (SOFCs) est necessaire afin de repondre aux enjeux actuels : abaissement de la temperature de fonctionnement, utilisation de metaux non precieux, flexibilite d’utilisation du carburant ou encore resistance a la degradation. A ces fins, u…
Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tun…
Pentablock copolymers comprised of multi-polymer blocks such as polyethylene glycol (PEG), polycaprolactone (PCL) and poly-lactide (PLA) were developed for fabrication of nanoparticles and thermosensitive hydrogel formulations for long term delivery of small and macromolecules. Different pentablock copolymer compositi…
Scope and Method of Study: Current study focused on understanding of "wetting" and "dewetting" phenomena between surfaces of single-walled carbon nanotubes (SWCNT) which are lightly grafted with polymer chains by reversible-deactivation radical polymerization, when they are mixed with matrix chains of the same archite…
Dislocation channel-veins and persistent slip bands (PSBs) are characteristic dislocation configurations that are of interest to both industry and academia. However, existing mathematical models are not adequate to describe the mechanism of the transition between these two states. In this thesis, a series of models ar…
