Transition from glass- to gel-like states in clay at a liquid interface
(Journal article; Peer reviewed, 2016)Colloidal clay in water suspensions are known to exhibit a multitude of bulk phases depending on initial colloidal concentration and ionic strength, and examples of this include repulsive Wigner colloidal glasses at low ... -
Transition from viscous fingers to foam during drainage in heterogeneous porous media
(Peer reviewed; Journal article, 2023)We investigate the behavior of drainage displacements in heterogeneous porous media finding a transition from viscous fingering to foam-like region. A pore network model incorporating the formation of blobs is adopted to ... -
Transmission electron microscopy and muon spin relaxation studies of precipitation in Al–Mg–Si alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:1, Doctoral thesis, 2014)The Al–Mg–Si system is a heat-treatable class of aluminium alloys that gain their mechanical strength via precipitation hardening. The main hardening phases are precipitated as needle-shaped nano-sized particles from a ... -
Transmission electron microscopy based characterization of CdTe–HgTe core–shell semiconductor nanowires
(Master thesis, 2020)Denne avhandlingen rapporterer resultatene fra tøyningskartlegging på heterostrukturerte CdTe–HgTe kjerne–skallnanotråder, tiltenkt å fungere som kvasiendimensjonale topologiske isolatorer. Tøyningskartlegging har blitt ... -
Transmission Electron Microscopy Characterisation of Lead-Free KNN Thin Films
(Master thesis, 2018)Lead-free piezoelectric ceramics have in recent years received an increased interest. Potassium sodium niobate (KNN) has shown promising results, exhibiting properties close to todays dominating piezoelectric material lead ... -
Transmission Electron Microscopy Characterization of Degradation Mechanisms in Lithium-ion Batteries
(Master thesis, 2022)Litium-ion batterier har fremtredd som en lovende løsning for det økende behovet for bærbare, effektive og billige energilagringsenheter. Grafitt har blitt brukt som anodemateriale i kommersielle litium-ion batterier siden ... -
Transmission electron microscopy characterization of quantum dot based intermediate band solar cells
(Master thesis, 2014)In this thesis, two samples of quantum dot based intermediate band solar cells were studied and compared by transmission electron microscopy. These samples were grown on a (100) GaAs substrate, with a general structure ... -
Transmission Electron Microscopy Characterization of Sintered and Hot-Pressed Silicon Carbide
(Master thesis, 2016)Silicon carbide has excellent mechanical properties. Sintered or hot-pressed (HP) SiC is essen- tial for applications that require dense bodies. In this work, the microstructure of one solid state sintered SiC and one ... -
Transmission electron microscopy studies of dispersoids and constituent phases in Al-Mn-Fe-Si alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:239, Doctoral thesis, 2014)3xxx aluminium alloys are used among others in packaging, architectural applications and heat exchangers. Both dispersoids and constituent phases are very important in this alloy system. The size and distribution of the ... -
Transmission Electron Microscopy Study of Two Peak Hardened Al-Mg-Si-Cu Alloys
(Master thesis, 2017)In this thesis, a variety of techniques within the field of transmission electron microscopy have been applied in the study of two dense 6xxx series aluminium alloys, at their peak hardness. This is a class of age-hardenable ... -
Transparent Colloidal Crystals With Structural Colours
(Peer reviewed; Journal article, 2022)Spatially ordered arrangements of spherical colloids are known to exhibit structural colours. The intensity and brilliance of these structural colours typically improve with colloidal monodispersity, low concentrations of ... -
