Ultrafast Optical and Magneto-Optical Kerr Effect Spectroscopy on Condensed Matter
(Master thesis, 2017)In this masters project, an ultrafast optical spectroscopy system has been constructed and tested. The system was built as an extension to an existing spectroscopy system, centered around a mode-locked Ti:Sapphire femtosecond ... -
Ultrafast self-healing and highly transparent coating with mechanically durable icephobicity
(Journal article; Peer reviewed, 2019)Excessive ice accretion on infrastructures can lead to severe damage and dysfunction. In the context of combating the build-up of unwanted icing and at the same time maintaining sunlight permeation, for instance on solar ... -
Ultrafast Spectroscopic Studies of Ferroelectric BaTiO3 Thin-Films on SrTiO3
(Master thesis, 2016)In this masters thesis ultrafast spectroscopic studies have been performed on single-crystal 111 strontium titanate, SrTiO3, and pulsed-laser deposited (PLD) thin-films of ferroelectric barium titante, BaTiO3. This has ... -
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
(Peer reviewed; Journal article, 2021)The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production of low-value products such as animal feed. While fish muscle is the primary product of use ... -
Ultrafine partikler fra øvelsesbranner: Kvantifisering av partikkelemisjoner gjennom brannforløp
(Master thesis, 2021)Brannkonstabler er mer utsatt for visse sykdommer og helseplager enn den generelle befolkningen, deriblant ulike former for kreft og hjertesykdom. På grunn av koblingen til kreftrisiko har stadig flere studier blitt gjort ... -
Ultrahigh thermoelectric performance in Cu2−ySe0.5S0.5 liquid-like materials
(Journal article, 2017)Liquid-like thermoelectric materials have recently received heightened attentions due to their exceptional thermal and electrical transport properties. As a typical example, Cu2−ySe has good electrical transport properties ... -
Ultrahigh-pressure form of Si O2 glass with dense pyrite-type crystalline homology
(Peer reviewed; Journal article, 2019)High-pressure synthesis of denser glass has been a longstanding interest in condensed-matter physics and materials science because of its potentially broad industrial application. Nevertheless, understanding its nature ... -
Ultrahigh-Pressure Nitrogen Arcs Burning Inside Cylindrical Tubes
(Journal article; Peer reviewed, 2018)When the pressure and temperature of a fluid exceed a critical point, the fluid enters into the supercritical (SC) region. In this region, the physical properties are believed to be in favor of a good current interruption ... -
Ultraprodukter og anvendelser i kommutativ algebra
(Bachelor thesis, 2024)Denne oppgaven gir en introduksjon til ultraprodukter, med sikte for å gjøre algebra med dem. Ultraproduktet, en konstruksjon fra modellteorien, er et slags gjennomsnitt av objektene det tar inn: Et ultraprodukt av ringer ... -
Ultrapure Wood Nanocellulose - Assessments of Coagulation and Initial Inflammation Potential
(Journal article; Peer reviewed, 2019)Using a lepirudin-based human whole blood model, we evaluated the initial inflammatory and coagulation responses of dense and porous ultrapure (<50 endotoxin units/grams) cellulose nanofibrils (CNF), of carboxylated grade. ... -
Ultraslow oscillations and emergence of sequential activity in the developing entorhinal cortex
(Master thesis, 2024)In the brain, the interaction of neurons leads to highly structured temporal patterns of neural activity coordination such as oscillations. One example brain region that exhibits oscillations is the medial entorhinal cortex ... -
Ultrasonic degassing of TDG supersaturated, flowing water

Ultrasonic detection of decompression induced vascular microbubbles
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:168, Doctoral thesis, 2007)Gassbobler kan dannes i kroppen som følge av overmetning av gasser når man går opp til overflaten etter dykking. Det har lenge vært kjent at slike gassbobler kan føre til trykkfallsyke, men mekanismene bak er fortsatt ikke ... -
Ultrasonic Evaluation of Clay Behind Casing
(Master thesis, 2017)There's an increasing number of oil fields on the Norwegian continental shelf that will go out of production in the coming years, resulting in a big demand for permanent plugging and abandonment (P&A) services. There are ... -
