Hydrothermal synthesis of SrxBa1–xNb2O6 on nanostructured substrates
(Master thesis, 2019)I nyere tid har syntese av bly-frie ferroelektriske materialer tiltrukket seg stadig mer oppmerksomhet og et av de studerte materialene er strontium barium niobat (SBN). SBN har vist gode elektro-optiske egenskaper, samt ... -
Hydrotreating of Bio-Oils over Metal-Phosphide Catalysts
(Master thesis, 2012)A concern over the impact of fossil fuels on the environment has made the researchers to look for more environmental options. One alternative is bio-oils produced from lignocellulosic material. However, the abundance of ... -
Hydroxyl airglow observations for investigating atmospheric dynamics: Results and challenges
(Peer reviewed; Journal article, 2023)Measurements of hydroxyl (OH*) airglow intensity are a straightforward and cost-efficient method which allows the derivation of information about the climate and dynamics of the upper mesosphere/lower thermosphere (UMLT) ... -
Hydroxyl Functionalized Pyridinium Ionic Liquids: Experimental and Theoretical Study on Physicochemical and Electrochemical Properties
(Journal article; Peer reviewed, 2019)Structurally modified hydroxyl functionalized pyridinium ionic liquids (ILs), liquid at room temperature, were synthesized and characterized. Alkylated N-(2-hydroxyethyl)-pyridinium ILs were prepared from alkylpyridines ... -
Hygienic standards and practices in Norwegian salmon Processing plants
(Journal article; Peer reviewed, 2017)The farmed salmon industry is important economically for several countries with Norway as the main producer constituting 53% of the world total. Bacterial contamination of salmon products may occur during processing, ... -
HyGreGel: A new class of gel systems for water diversion by in-depth reservoir placement
(Doctoral theses at NTNU;2019:336, Doctoral thesis, 2019)High water production is typically a major problem late in the life cycle of a water flooded hydrocarbon reservoir. Reservoir heterogeneity plays a significant role in creating this problem. An example is highly permeable ... -
Hygroscopic buffering effects in exposed cross-laminated timber surfaces and indoor climate in a Norwegian primary school
(Peer reviewed; Journal article, 2022)Laboratory studies have shown that wood has hygroscopic properties. When used as a construction material in buildings, it can thus influence indoor relative humidity and temperature. Ventilation can affect indoor climate ... -
Hygrothermal Aging of Amine Epoxy: Reversible Static and Fatigue Properties
(Journal article; Peer reviewed, 2018)Fiber-reinforced polymers (FRP) are widely used in structural applications. Long-term properties of such materials exposed to water are of high concern and interest, especially for subsea and offshore applications. The ... -
Hygrothermal Modeling of Masonry with Interior Insulation Retrofit - Perspectives on hygrothermal performance and modeling-uncertainty
(Doctoral theses at NTNU;2024:43, Doctoral thesis, 2024)Energy retrofit of existing buildings is mainly an endeavor to reduce energy consumption. Interior insulation retrofit of masonry falls among retrofit measures in this regard. However, interior insulation of masonry may ... -
Hygrothermal performance of ventilated wooden cladding
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:31, Doctoral thesis, 2010)This PhD project contributes to more accurate design guidelines for high-performance building envelopes by analysis of hygrothermal performance of ventilated wooden cladding. Hygrothermal performance is defined by cladding ... -
Hygrothermal Properties of Compressed Earthen Bricks
(Journal article; Peer reviewed, 2018)The present study investigates the relationship between bulk density and hygrothermal behaviour of compressed earthen bricks. The experimental results show that the thermal conductivity linearly increases from 0.5228 W/(m ... -
Hygrothermal Simulation of Interior Insulated Brick Wall - Perspectives on Uncertainty and Sensitivity
(Peer reviewed; Journal article, 2023)Energy retrofit of existing masonry buildings has become attractive to meet demands for reduction in energy consumption. Retrofit may, however, introduce moisture risk that needs to be assessed. Hygrothermal simulation ... -
Hygrothermal simulations of thermally insulated basement envelopes - Importance of boundary conditions below grade
(Peer reviewed; Journal article, 2021)Hygrothermal simulations are widely used to predict and optimise the hygrothermal performances of building envelopes. For the walls and floors in basements, however, determining the variation of the exterior hygrothermal ... -
Hylleplassering og salg
(Bachelor thesis, 2010)Denne oppgaven er skrevet på oppdrag fra Shell/7-eleven Gjøvik og skal se på effekten hylleplassering har på salget. Del 1 gir et bilde av varehandelen i Norge og viser at en stor del av verdiskapningen i norsk næringsliv ... -
