Temperatur og salinitets påvirkning på viskositeten til delvis hydrolyserte polymer med og uten hydrofobe substituenter
(Master thesis, 2017-09-15)I denne oppgaven sammenlignes viskositetsutviklingen som funksjon av temperatur for to hydrofobisk modifiserte polyelektrolytter og en polyelektrolytt uten hydrofobe substituenter. Målingene er utført ved to ulike ... -
Temperature induced color change in gold nanoparticle arrays: Investigating the annealing effect on the localized surface plasmon resonance
(Peer reviewed; Journal article, 2016)The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for a range of applications, including photovoltaics and sensors. The actual LSPR effect is difficult to predict, because it can ... -
Temperature-Dependent Bending Rigidity of AB-Stacked Bilayer Graphene
(Journal article; Peer reviewed, 2021)The change in bending rigidity with temperature κ(T) for 2D materials is highly debated: theoretical works predict both increase and decrease. Here we present measurements of κ(T), for a 2D material: AB-stacked bilayer ... -
Temporal characteristics and energy deposition of pulsating auroral patches
(Peer reviewed; Journal article, 2016-07-23)We present a careful statistical analysis of pulsating aurora (PA) using all-sky green line (557.7 nm) images obtained at 3.3 Hz. Six well-defined individual PA patches are identified and extracted using a contouring ... -
The Temporal Relationship Between Terrestrial Gamma-Ray Flashes and Associated Optical Pulses From Lightning
(Journal article; Peer reviewed, 2022)We present 221 Terrestrial Gamma-ray Flashes (TGFs) and associated optical pulses observed by the Atmosphere-Space Interactions Monitor (ASIM) on board the International Space Station. The events were detected between the ... -
Teoretisk- och Praktisk Analys av Avsäkrings- och Fackelsystemet på Isokrackeranläggningen, Preemraff Lysekil
(Master thesis, 2017)I processindustrin finns krav på att säkerhetsventiler ska finnas installerade på processenheter där trycket av någon orsak kan överskrida designtrycket av enheten. Det är av stor vikt att dessa säkerhetsventiler har ... -
Terrestrial Gamma-Ray Flashes With Accompanying Elves Detected by ASIM
(Journal article; Peer reviewed, 2022)The Atmosphere-Space Interactions Monitor was designed to monitor Terrestrial Gamma-ray Flashes (TGFs) and Transient Luminous Events (TLEs) from space, enabling the study of how these phenomena are related. In this paper, ... -
Test of CP invariance in vector-boson fusion production of the Higgs boson in the H → ττ channel in proton–proton collisions at √s = 13 TeV with the ATLAS detector
(Journal article; Peer reviewed, 2020)A test of CP invariance in Higgs boson production via vector-boson fusion is performed in the H→ττ decay channel. This test uses the Optimal Observable method and is carried out using 36.1fb−1 of s=13TeV proton–proton ... -
Test of the universality of τ and μ lepton couplings in W-boson decays with the ATLAS detector
(Journal article; Peer reviewed, 2021)The standard model of particle physics encapsulates our best current understanding of physics at the smallest scales. A fundamental axiom of this theory is the universality of the couplings of the different generations of ... -
Testing Fluorescence Lifetime Standards using Two-Photon Excitation and Time-Domain Instrumentation: Fluorescein, Quinine Sulfate and Green Fluorescent Protein
(Peer reviewed; Journal article, 2018-09)It is essential for everyone working with experimental science to be certain that their instruments produce reliable results, and for fluorescence lifetime experiments, information about fluorescence lifetime standards is ... -
Testing Fluorescence Lifetime Standards using Two-Photon Excitation and Time-Domain Instrumentation: Rhodamine B, Coumarin 6 and Lucifer Yellow
(Peer reviewed; Journal article, 2014-05-28)Having good information about fluorescence lifetime standards is essential for anyone performing lifetime experiments. Using lifetime standards in fluorescence spectroscopy is often regarded as a straightforward process, ... -

Testing the presence of CP violation in the 2HDM
(Peer reviewed; Journal article, 2015-04-27)We review CP properties of the Two-Higgs-Doublet model. In particular, we show that sponta- neous CP violation occurs in the parameter space on the border between regions allowing explicit CP violation and those where there ... -
