Ultra-robust icephobic coatings with high toughness, strong substrate adhesion and self-healing capability
(Peer reviewed; Journal article, 2022)Enabling surfaces with passive anti-icing properties is an emerging, facile, economical, and energy-saving strategy to mitigate the harm caused by ice accretion. However, the combination of icephobicity and robustness still ... -
Ultra-short pulsed Tm- and Er-doped all-fiber MOPA lasers and supercontinuum sources.
(Doctoral thesis, 2016-12-12)The present work describes the results of the development of a family of novel diode-pumped ultra-short and short pulsed Er- and Tm-fiber laser systems in the “eye-safe” near- and mid-Infrared (mid-IR) wavelength range for ... -
Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated
(Peer reviewed; Journal article, 2022)Per- and polyfluoroalkyl substances (PFASs) have been a focal point of environmental chemistry and chemical regulation in recent years, culminating in a shift from individual PFAS regulation toward a PFAS group regulatory ... -
Ultrabroad Continuous-Wave Tuning of Ceramic Cr:ZnSe and Cr:ZnS Lasers
(Chapter, 2010)Using a single set of optics, we demonstrate ultrabroad tuning over more than 1300 nm from 1973 to 3349 nm in Cr:ZnSe and from 1962 to 3195 nm in Cr:ZnS at <10 GHz linewidth. -
Ultrafast control of spin interactions in honeycomb antiferromagnetic insulators
(Journal article; Peer reviewed, 2019)Light enables the ultrafast, direct, and nonthermal control of the exchange and Dzyaloshinskii-Moriya interactions. We consider two-dimensional honeycomb lattices described by the Kane-Mele-Hubbard model at half filling ... -
Ultrafast fiber-based lasers beyond 2 µm
(Chapter, 2017)The talk reviews recent advances in fiber based ultrafast mid-IR lasers and frequency combs, outlines the trends in materials as well as novel approaches for generation of ultra-broadband spectra above 2 mm. -
Ultrafast generation and dynamics of isolated skyrmions in antiferromagnetic insulators
(Peer reviewed; Journal article, 2019)Based on atomistic spin dynamics simulations, we report the ultrafast generation of single antiferromagnetic (AFM) skyrmions in a confined geometry. This process is achieved through an effective magnetic field induced by ... -
Ultrafast magnon-phonon dynamics
(Master thesis, 2022)Kontroll av magnetisme ved bruk av ultraraske laserpulser har tiltrukket seg mye oppmerksomhet de siste tiårene. Dette har resultert i intensiv forskning, både teoretisk og eksperimentell, for å forstå de mikroskopiske ... -
Ultrafast manipulation of Heisenberg exchange and Dzyaloshinskii–Moriya interactions in antiferromagnetic insulators
(Master thesis, 2019)Light enables ultrafast, direct and nonthermal control of the exchange and Dzyaloshinskii-Moriya interactions. We consider two-dimensional honeycomb lattices described by the Kane-Mele-Hubbard model at half filling and in ... -
Ultrafast Microscopy Imaging of Acoustic Cluster Therapy Bubbles: Activation and Oscillation
(Peer reviewed; Journal article, 2022)Acoustic Cluster Therapy (ACT®) is a platform for improving drug delivery and has had promising pre-clinical results. A clinical trial is ongoing. ACT® is based on microclusters of microbubbles–microdroplets that, when ... -
Ultrafast nonlocal collective dynamics of Kane plasmon-polaritons in a narrow-gap semiconductor
(Journal article; Peer reviewed, 2019)The observation of ultrarelativistic fermions in condensed-matter systems has uncovered a cornucopia of novel phenomenology as well as a potential for effective ultrafast light engineering of new states of matter. While ... -
Ultrafast Two-Magnon Excitation in Two-Dimensional Antiferromagnetic Insulators
(Master thesis, 2020)Spinneksitasjoner i todimensjonale antiferromagnetiske materialer manifesteres som spinnbølger som også er kjent som magnoner. Magnoner er bosoniske kvasipartikler som kan eksiteres ved hjelp av en laserindusert forstyrrelse ... -
Ultrafiltration of Partially Degraded Starch Solution
(Dr.ingeniøravhandling, 0809-103X; 2002:87, Doctoral thesis, 2002)Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from ... -
Ultrafiltration of Saithe (Pollachius virens) Protein Hydrolysates and Its Effect on Antioxidative Activity
