Hot corrosion of Gd2Zr2O7, Gd2Zr2O7/YbSZ, YSZ+Gd2Zr2O7/YbSZ, and YSZ thermal barrier coatings exposed to Na2SO4+V2O5.
(Peer reviewed; Journal article, 2020)Gd2Zr2O7 ceramic is considered as a potential candidate for thermal barrier coatings. Here we present hot corrosion behavior of single layer Gd2Zr2O7 (GZO), Gd2Zr2O7 + 50 wt% YbSZ (GZO/YbSZ), YSZ and double-layer ... -
Hot electron enhanced photoemission from laser fabricated plasmonic photocathodes
(Peer reviewed; Journal article, 2023)Photocathodes are key elements in high-brightness electron sources and ubiquitous in the operation of large-scale accelerators, although their operation is often limited by their quantum efficiency and lifetime. Here, we ... -
Hot gas cleaning
(Master thesis, 2014)Five H2S adsorbent materials for hot gas cleaning of biomass-derived synthesis gas were prepared. Three of the new sorbents were prepared based on a novel manganese-based sorbent that uses alumina support. The new adsorbent ... -
Hot Pressing and Characterization of Powder Based Silicon Substrates for Photovoltaic Applications.
(Master thesis, 2012)High purity silicon material in solar cell fabrication constitutes 40% of the total cost for conventional solar cell production. One approach to reduce costs would be to use less of this expensive silicon by making thin ... -
Hot pressing and degradation of TiB inert cathodes
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:127, Doctoral thesis, 2009)Primary aluminium production is an energy intensive process, and the aluminiumindustry strives to lower the energy consumption. However, with the current technology a considerable reduction in the energy consumption is ... -
Hot-water Extraction of Hemicelluloses by Microwave Heating: A Study of Sugarcane Bagasse and Sawmill Shavings of Norway Spruce and Scots Pine as Raw Materials for Hemicellulose Extraction
(Master thesis, 2012)In light of the increasing focus on sustainability and bio-mass as feedstock for energy and chemicals, extraction of hemicelluloses from different kinds of lignocellulosic materials has received much attention. This thesis ... -
Household Reliance on Environmental Income in the Western Serengeti Ecosystem, Tanzania
(Journal article; Peer reviewed, 2019) -
How are popragylamines synthesised, how has the synthesis become greener and what are they used for?
(Bachelor thesis, 2023)Ulike syntese metoder for dannelse av propargylaminer har blitt analysert og metodene har blitt satt i tidsperspektiv. Det er to hoved typer måter propargylaminer kan bli dannet på. Først ved å substituere en funksjonell ... -
How calcium prevents precipitation hardening in Al–Mg–Si alloys
(Journal article, 2013)We have investigated the effect on precipitate microstructure and hardness upon adding small amounts of Ca to a base Al–Mg–Si alloy. The main investigative techniques were transmission and scanning electron microscopy. We ... -
How can mariculture better help feed humanity?
(Peer reviewed; Journal article, 2015)The primary production of the marine and the terrestrial domains are similar, ~49 and 56 Gt C year−1, respectively (Field et al., 1998), and the marine primary production must likely be more readily available for grazing ... -
How can proteins, lipids and astaxanthin be extracted from snow crab (Chionoecetes opilio) rest raw material in a sustainable manner?
(Master thesis, 2019)Den norske fangsten av snøkrabbe (Chionoecetes opilio) genererer store mengder restråstoff som kastes på havet. Dette restråstoffet er en god kilde for proteiner, lipider og astaxantin til bruk i produksjon av mat og fôr. ... -
How do conditions at birth influence early‐life growth rates in wild boar?
(Peer reviewed; Journal article, 2020)Weather conditions and population density individuals experience at birth influence their life-history traits and thereby population dynamics. Early-life individual growth is a key fitness-related trait; however, how it ... -
How do different nitrogen application levels and irrigation practices impact biological nitrogen fixation and its distribution in paddy system?
(Peer reviewed; Journal article, 2021)Background and aims Biological nitrogen fixation (BNF) in paddy systems is impacted by nitrogen application levels and irrigation strategies, but the extent to which these factors influence BNF and its distribution in ... -
How do lichens, willow shrubs, meadow, and heath plant communities affect microclimate?
(Master thesis, 2022)Increases in earth's surface temperature because of climate change in the last decades have already shown consequences in different ecosystems and in different taxonomic groups. Alpine environments are among the most ... -
How does a forest herb species change its reproductive allocation patterns in response to microclimate variation
(Master thesis, 2019)Rapid environmental changes induced plant species to modify their migration range to meet ecological tolerance. It mainly brought difficulties to slow colonizing forest understory species, because such changes already ... -
How does human disturbance affect brood parasitism and nest predation in hosts inhabiting a highly fragmented landscape?
(Peer reviewed; Journal article, 2020)Human disturbance represents a considerable challenge for the conservation of living organisms and has profound negative impacts globally. There is substantial variation in how species respond to human disturbance. The ... -
How Does Spring Migration and Day Length Affect the Diving Ecology of a Capital Breeder Wintering at High Latitudes?
(Master thesis, 2016)Foraging strategies in animals are influenced by conflicting constraints such as migration, reproduction and seasonal changes in the environment. Sea ducks are capital breeders and rely on endogenous reserves for reproduction. ... -
How far can we stretch the timescale with RETIS?
(Peer reviewed; Journal article, 2023)Molecular dynamics (MD) and Monte Carlo (MC) have long coexisted as two main independent branches of molecular simulation. In the late eighties, however, algorithms based on the combination of both were created such as ... -
