Green Ironmaking - Carburization of Green Direct Reduced Iron (DRI)
(Bachelor thesis, 2023)Dagens mest vanlige måte å lage jern fra jernmalm på er ved bruk av masovn, som produserer en stor mengde CO2-utslipp hvert år. Et grønnere alternativ til masovn er Direkte Reduksjon av Jern (DRI), som bruker reduksjonsgasser, ... -
Green Ironmaking – Direct Reduction of Iron Ore Pellets with Hydrogen Gas at Varying Temperature
(Bachelor thesis, 2023)Dagens jernproduksjon (Fe) med masovner er et voksende miljøproblem, ettersom det brukes store mengder med råmaterialer som bidrar til mye CO2-utslipp. Direkte redusert jernproduksjon (DRI) med hydrogen (H2) har vekket ... -
Green River Kerogen Product Distribution Analysis: The Influence of Pyrolysis and Catalytic Reactions with Hydrogen-Donor Solvent
(Master thesis, 2016)The increase in global energy consumption of petroleum, which is estimated to even surge to ca. 37% by 2035, requires substitutes from other unconventional sources of oil and gas. Utilization of oil shale by technology and ... -
Green synthesis of gold nanoparticles and its application in cancer treatment
(Bachelor thesis, 2024)Gull nanopartikler (AuNPs) spiller en betydelig rolle i både medisinske og ikke-medisinske felt på grunn av deres unike egenskapene. Grønn syntese metoder tilbyr en miljømessig bærekraftig tilnærming til å produsere AuNP-er ... -
Green synthesis of silver nanoparticles for medicinal purposes
(Bachelor thesis, 2023)Sølv nanopartikler (AgNP), blant andre nanopartikler, er kjent på grunn av deres unike egenskaper. For å bidra til studiet av medisin og behandling av sykdommer som kreft, syntetiseres de, vanligvis ved hjelp av ekstrakter ... -
Green’s Function Approach to Quantum Phenomena in Heterostructures with Spin- Polarization and Coherence
(Doctoral theses at NTNU;2023:238, Doctoral thesis, 2023)Kvantemekanikken som muliggjør fremtidens informasjonsteknologi Moderne datamaskiner produserer en mengde varme som er sammenlignbart med varmen fra panelovner. Denne varmeproduksjonen, sammen med utfordringer relatert ... -
GREM1 is associated with metastasis and predicts poor prognosis in ER-negative breast cancer patients
(Journal article; Peer reviewed, 2019)Background In breast cancer, activation of bone morphogenetic protein (BMP) signaling and elevated levels of BMP-antagonists have been linked to tumor progression and metastasis. However, the simultaneous upregulation of ... -
Gross Growth Efficiency of Daphnia magna:Genetic Variance and Effects of Temperature
(Master thesis, 2017)Gross Growth Efficiency (GGE) is defined as the ratio between Somatic Growth Rate (SGR) and food consumption, and hence represents the quantity of food eaten that is converted to body mass. SGR correlates with intrinsic ... -
Ground-Based UV Measurements, Aerosol Effects on UV Radiation
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:39, Doctoral thesis, 2009) -
Growing gold nanostructures for shape-selective cellular uptake
(Journal article; Peer reviewed, 2018)With development in the synthesis of shape- and size-dependent gold (Au) nanostructures (NSs) and their applications in nanomedicine, one of the biggest challenges is to understand the interaction of these shapes with ... -
Growing up in a changing climate: how temperature affects the development of morphological, behavioral and physiological traits of a marsupial mammal
(Peer reviewed; Journal article, 2020)Climate change is likely to affect many mammalian phenotypes, yet little is known whether and how phenotypic plasticity is involved in responding to thermal challenges during mammalian development. We investigated the ... -
Growth and Aggregation Phenomena in Precipitation of Calcium Carbonate
(Dr. ingeniøravhandling, 0809-103X; 2001:49, Doctoral thesis, 2001)Particle size-enlargement processes in precipitation of calcium carbonate have been investigated by focusing on determination of crystal growth rates and aggregation rates of the metastable polymorph vaterite. This was ... -
Growth and behaviour of blue mussels, a re-emerging polar resident, follow a strong annual rhythm shaped by the extreme high Arctic light regime: Mussels' growth and behavior in Arctic
(Peer reviewed; Journal article, 2020)Polar regions are currently warming at a rate above the global average. One issue of concern is the consequences on biodiversity in relation to the Northward latitudinal shift in distribution of temperate species. In the ... -
Growth and Biochemical Composition of Cultivated Mixed Biofilm on Wastewater from Recirculating Aquaculture Systems (RAS)
