Time-dependent water uptake in a polymer model coating visualized by FTIR microscopy using a focal plane array detector
(Chapter, 2016)Progress of the delamination front during cathodic delamination was imaged by FTIR microscopy. Delamination experiments were carried out using H2O and D2O-based electrolytes. Inhomogeneous propagation of the delamination ... -
Time-enhanced performance of oxide thermoelectric modules based on a hybrid p-n junction
(Peer reviewed; Journal article, 2021)The present challenge with all-oxide thermoelectric modules is their poor durability at high temperatures caused by the instability of the metal-oxide interfaces at the hot side. This work explains a new module concept ... -
Time-Evolved SERS Signatures of DEP-Trapped Aβ and Zn2+Aβ Peptides Revealed by a Sub-10 nm Electrode Nanogap
(Peer reviewed; Journal article, 2021)Alzheimer’s disease (AD) has become highly relevant in aging societies, yet the fundamental molecular basis for AD is still poorly understood. New tools to study the undergoing structural conformation changes of amyloid ... -
Tin and Tin Alloys for Low Cost Bipolar Plates in PEM Fuel Cells
(Doctoral theses at NTNU;2020:408, Doctoral thesis, 2020)Proton Exchange Membrane (PEM) Fuel Cells are one of the most promising futures for green energy, as they provide a sustainable alternative to combustion engines in vehicles. The bipolar plate (BPP) is a crucial component ... -
Titanium Carbide Coating on Graphene Nanoplatelets
(Peer reviewed; Journal article, 2020)Titanium carbide was formed on graphene nanoplatelets (GNPs) using potassium hexa-fluorotitanate (K2TiF6) salt in the presence of pure aluminium. K2TiF6 - GNPs mixture with titanium to carbon ratio of 5:1 was heated at a ... -
Topological defects in hexagonal manganites - Inner structure and emergent electrostatics
(Journal article; Peer reviewed, 2017)Diverse topological defects arise in hexagonal manganites, such as ferroelectric vortices, as well as neutral and charged domain walls. The topological defects are intriguing because their low symmetry enables unusual ... -
Topological domain walls in helimagnets
(Journal article; Peer reviewed, 2018)Domain walls naturally arise whenever a symmetry is spontaneously broken. They interconnect regions with different realizations of the broken symmetry, promoting structure formation from cosmological length scales to the ... -
Toughening of Y-doped BaZrO3 proton conducting electrolytes by hydration
(Journal article; Peer reviewed, 2017)In BaZr1−xYxO3−x/2 (BZY), the state-of-the-art oxide proton conductors, the proton conductivity is facilitated by hydration of oxygen vacancies. Hydration induces lattice expansion, which may induce stress and thereby ... -
Toward the recovery of solar silicon from end-of-life PVs by vacuum refining
(Peer reviewed; Journal article, 2023)Considering the boom of Si solar cell installation, it is necessary to establish a process for recycling of Si from End-of-life photovoltaics (PVs). Silicon in the PVs is synthetically doped and coated by various elements ... -
