Kerr-Lens Mode-locked Cr:ZnS Laser
(Chapter, 2012)The first Kerr-Lens mode-locked Cr:ZnS laser generates the shortest and highest-energy mid-IR near transform-limited pulses of 69 fs duration at 550 mW output power. The 3.7 nJ pulses have 193 nm wide spectrum around 2.39 µm -
Kerr-lens mode-locked Cr:ZnS laser
(Journal article; Peer reviewed, 2013)We report the soft-aperture Kerr-lens mode-locked Cr:ZnS laser, generating 550 mW of 69 fs nearly transform-limited pulses at 2.39 μm wavelength. The pulse energy reached 3.8 nJ at 145 MHz repetition rate, limited by the ... -
Key to xenobiotic carotenoids
(Journal article; Peer reviewed, 2012)A listing of carotenoids with heteroatoms (X = F, Cl, Br, I, Si, N, S, Se, Fe) directly attached to the carotenoid carbon skeleton has been compiled. The 178 listed carotenoids with C,H,X atoms demonstrate that the ... -
Kimdanning av sprøbrudd i et 420 MPa arktisk stål
(Master thesis, 2011)Sveising fører til endret mikrostruktur i deler av stålet. I kombinasjon med lave temperaturer oppstår nye forutsetninger for brudd.I denne masteroppgava ble det sett på initiering av sprøbrudd i et sveisesimulert 420 ... -
Kimdanning av sprøbrudd i simulert grovkornet HAZ i et arktisk stål
(Master thesis, 2012)Det har blitt estimert at 30 % av verdensuoppdagede gassreserver og 13 % av verdens uoppdagede oljereserver ligger i de polare områdene i nord. Man trenger derfor materialer som tåler lave temperaturer for å hente opp denne ... -
Kinetic and Deactivation Studies of Hydrodesulfurization Catalysts
(Dr. ingeniøravhandling, 0809-103X; 2002:148, Doctoral thesis, 2002)Hydrodesulfurization is an important part of the hydrotreating process. More stringent regulations on the quality of fuels bring new requirements to the catalytic processes. The removal of sulfur has become a key issue in ... -
Kinetic and Isotherm Modelling for the Investigation of Adsorption of Pharmaceuticals onto Suspended Particles in Marine Environmental Conditions
(Master thesis, 2022)Legemidler er nylig oppdagede forurensende forbindelser som slippes ut i det marine miljøet uten særlig omtanke. Man tror at adsorpsjon til suspenderte partikler kan bidra til akkumulering av legemidler i havet, noe som ... -
