Ultra høyfast betong med fiberarmering og testing av Da Vinci brumodell
(Master thesis, 2014)I 2010 bygget en gruppe studenter ved NTNU en bru i ultrahøyfast fiberbetong som en del av et studieprosjekt. Brua er slank og spenner over 3 meter. Den er fiberarmert med 2 vol-% stålfiber på 3.5cm. I 2010 ble det utført ... -
Ultra Long Extended Reach Drilling
(Master thesis, 2010)With the notion of evolving current Extended Reach Drilling, this master thesis examines if drilling 20–40km is feasible. Several reservoirs offshore in the area outside of Lofoten in the northern part of Norway are reachable ... -
Ultra-Cheap Renewable Energy as an Enabling Technology for Deep Industrial Decarbonization via Capture and Utilization of Process CO2 Emissions
(Peer reviewed; Journal article, 2022)Rapidly declining costs of renewable energy technologies have made solar and wind the cheapest sources of energy in many parts of the world. This has been seen primarily as enabling the rapid decarbonization of the electricity ... -
Ultra-durable Icephobic Coating by Molecular pulley
(Journal article; Peer reviewed, 2019)Slide-ring crosslinked polydimethylsiloxane (PDMS) is designed and prepared for anti-icing/deicing application. Compared with the covalent crosslinks, the slidable crosslinks enhance the mobility of polymer networks and ... -
Ultra-high energy density integrated polymer dielectric capacitors
(Peer reviewed; Journal article, 2022)Flexible dielectric polymers with high energy storage density are needed for film capacitor applications including hybrid electric vehicles and medical apparatuses. Poly(vinylidene fluoride) (PVDF) is regarded as a promising ... -
Ultra-high surface area and mesoporous N-doped carbon derived from sheep bones with high electrocatalytic performance toward the oxygen reduction reaction
(Journal article; Peer reviewed, 2017)A nitrogen (N)-doped mesoporous carbon material exhibiting ultra-high surface area was successfully synthesized from sheep bones via a facile and low-cost method. The obtained carbon material had an ultra-high specific ... -
An Ultra-Low Temperature Transcritical R744 Refrigeration System for Future Detectors at CERN LHC
(Peer reviewed; Journal article, 2021)The cooling systems of the future tracking detectors of the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN will be entirely based on CO2 refrigeration technology. The system is a booster refrigeration ... -
Ultra-Low-Temperature Refrigeration Systems: A Review and Performance Comparison of Refrigerants and Configurations
(Peer reviewed; Journal article, 2023)During the last decade, many industrial and medical applications have shown a requirement for low-temperature-cooling usage (from −40 to −80 °C), which cannot be efficiently obtained via the conventional refrigeration ... -
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 ... -
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 ... -
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 ... -
Ultrasonic Evaluation of Well Integrity
(Master thesis, 2014)This thesis presents the acoustic theory behind current ultrasonic cement evaluation tools. The UltraSonic Imager tool's pulse echo technique and the new Isolation Scanner tool's pitch-catch leaky lamb wave measuring ... -
Ultrasonic NDT and its Ability to Detect Pitting Corrosion Behavior on Carbon Steel
