Labeling nanoparticles: Dye leakage and altered cellular uptake
(Journal article, 2016)In vitro and in vivo behavior of nanoparticles (NPs) is often studied by tracing the NPs with fluorescent dyes. This requires stable incorporation of dyes within the NPs, as dye leakage may give a wrong interpretation of ... -
Silicon Optical Fibres - Past, Present and Future
(Journal article; Peer reviewed, 2016)This paper reviews the past, present and prospective future of silicon optical fibres. The incorporation of silicon with its rich optoelectronic functionality into existing glass fibre technologies presents a route to ... -
Dynamical tuning between nearly perfect reflection, absorption, and transmission of light via graphene/dielectric structures
(Journal article; Peer reviewed, 2016)Exerting well-defined control over the reflection (R), absorption (A), and transmission (T) of electromagnetic waves is a key objective in quantum optics. To this end, one often utilizes hybrid structures comprised of ... -
Escape model for Galactic cosmic rays
(Peer reviewed; Journal article, 2016)We show that the cosmic ray (CR) knee can be entirely explained by energy-dependent CR leak-age from the Milky Way, with an excellent fit to all existing data. We test this hypothesis cal-culating the trajectories of ... -
Compact Diode-pumped Dispersion-managed SESAM-mode-locked Ho:fiber Laser
(Chapter, 2016)We demonstrate for the first time a compact mode-locked holmium fiber laser diode-pumped at 1150 nm. The laser was operated in the dispersion-managed dissipative-soliton regime and provided 3.7 nJ pulse energy at 7.8 MHz PRF -
Expression of two Cell Membrane Proteins, CD37 and PD-L1, in Acute Myeloid Leukemia Cell Lines
(Master thesis, 2016)The standard chemotherapy treatment given to newly diagnosed Acute Myeloid Leukemia ( AML ) patients have remained practi- cally the same for the last forty years, and is poorly tolerated by the older patients. Several new ... -
Geometric Aspects of Quantum Entanglement
(Doctoral thesis at NTNU;2016:253, Doctoral thesis, 2016)Summary: Entanglement is a strange feature contained in the quantum mechanical framework, first observed theoretically by Erwin Schrödinger and Albert Einstein. An inherent attribute of entanglement is non-locality, and ... -
Quasiclassical Theory Beyond 1D: Supercurrents and Topological Excitations
(Master thesis, 2016)The finite element method is used to solve the quasiclassical Usadel equation, valid for diffusive superconducting hybrid systems, in higher dimensions than one. A detailed derivation of the method is given, and it is ... -
Experimental Evaluation of Broadband Wave Propagation in Plates
(Master thesis, 2016)As the number of aging oil field in the North Sea is increasing, the number of plug and abandonment (P&A) jobs which has to be conducted on the wells going out of production, e.g. to prevent hydrocarbons from leaking out ... -
Continuous water adsorption states promoted by Ni2+ confined in a synthetic smectite
(Journal article, 2016)The water adsorption isotherms of Ni-fluorohectorite have been obtained from the relative humidity dependence of X-ray diffraction intensities, and continuous transitions between the stable hydration states were observed. ... -
Recovering fluorophore concentration profiles from confocal images near lateral refractive index step changes
(Peer reviewed; Journal article, 2016)Optical aberrations due to refractive index mismatches occur in various types of microscopy due to refractive differences between the sample and the immersion fluid or within the sample. We study the effects of lateral ... -
Acoustic Cluster Therapy (ACT) - pre-clinical proof of principle for local drug delivery and enhanced uptake.
(Journal article; Peer reviewed, 2016)Proof of principle for local drug delivery with Acoustic Cluster Therapy (ACT) was demonstrated in a human prostate adenocarcinoma growing in athymic mice, using near infrared (NIR) dyes as model molecules. A dispersion ... -
Elemental electron energy loss mapping of a precipitate in a multi-component aluminium alloy
(Journal article, 2016)The elemental distribution of a precipitate cross section, situated in a lean Al-Mg-Si-Cu-Ag-Ge alloy, has been investigated in detail by electron energy loss spectroscopy (EELS) and aberration corrected high angle annular ... -
Coherent octave-spanning mid-infrared supercontinuum generated in As2S3-silica double-nanospike waveguide pumped by femtosecond Cr:ZnS laser
(Journal article; Peer reviewed, 2016)A more than 1.5 octave-spanning mid-infrared supercontinuum (1.2 to 3.6 μm) is generated by pumping a As2S3-silica “double-nanospike” waveguide via a femtosecond Cr:ZnS laser at 2.35 μm. The combination of the optimized ... -
The Vacuum Polarisation Contribution to the Lamb Shift Using Non-Relativistic Quantum Electrodynamics
(Master thesis, 2016)In this thesis we calculate the vacuum polarisation contribution to the well-known Lamb shift. The Lamb shift is a correction of order $\alpha^5$ to the non-relativistic energy spectrum of the hydrogen atom. We discuss the ... -
