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 ... -
Growth in Environmental Footprints and Environmental Impacts Embodied in Trade: Resource Efficiency Indicators from EXIOBASE3
(Journal article; Peer reviewed, 2018)Most countries show a relative decoupling of economic growth from domestic resource use, implying increased resource efficiency. However, international trade facilitates the exchange of products between regions with disparate ... -
Growth in international spillovers of energy and relation to development
(Master thesis, 2017)The production of goods and services demands direct and indirect use of energy. In this thesis, the production based and the consumption based use of energy is studied. Using the Multi Regional Input Output (MRIO) ... -
Grunnvannsbaserte varmepumper Tilrettelegging for bruk av grunnvann til oppvarming og kjøling i Melhus sentrum - sentralisert løsning
(Master thesis, 2017)I et grunnvannsbasert energisystem er det helt essensielt å benytte grunnvannet indirekte som varmekilde til varmepumper. Dette kommer som en følge av utfellinger av metallioner som danner et belegg på varmeveksleren. ... -
Grunnvannsvarmepumpe i fjernkjøle- og fjernvarmesystemer
(Master thesis, 2021)Det er flere fordeler med en felles distribusjonskrets i Melhus. Det gjør den fornybare ressursen tilgjengelig for flere, ved at bygg på områder der det ikke er gunstig å bore brønner kan koble seg til fellesnettet. Denne ... -
Grønn hydrogenproduksjon i det nedlagte vannkraftverket Nedre Fiskumfoss - en tekno-økonomisk analyse
(Bachelor thesis, 2022)Nedre Fiskumfoss kraftverk skal erstattes av et nytt kraftverk og i den sammenheng har NTE besluttet å undersøke hvorvidt det er mulig å produsere grønn hydrogen ved elektrolyse i det gjenstående bygget som en del av deres ... -

H2S removal technologies for maturing oil fields with sea water injection
(Master thesis, 2018)Enhanced oil and gas recovery is often performed with seawater injection in the well as pressure compensating mean. With it, potential challenges arise. Microbiological souring is considered a major contributor to the ... -
Habitat fragmentation amplifies threats from habitat loss to mammal diversity across the world’s terrestrial ecoregions
(Peer reviewed; Journal article, 2021)Global biodiversity is increasingly threatened by anthropogenic environmental change. While there is mounting evidence that habitat loss is a key threat to biodiversity, global assessments typically ignore additional threats ... -
Happier with less? Members of European environmental grassroots initiatives reconcile lower carbon footprints with higher life satisfaction and income increases
(Journal article; Peer reviewed, 2020)Scientists and policymakers recognize the need to address consumption and lifestyles in order to reconcile environmental and development agendas. Sustainability-oriented grassroots initiatives emerge bottom-up to create ... -
Harnessing thermoelectric power from transient heat sources: Waste heat recovery from silicon production
(Journal article; Peer reviewed, 2017)Thermoelectric generators (TEGs) are compact and robust devices for converting heat into electrical power. In this work, we investigate the response of a bismuth-telluride based TEG to the transient environment of a silicon ... -
Headline Environmental Indicators Revisited with the Global Multi-Regional Input-Output Database EXIOBASE
(Journal article; Peer reviewed, 2018)Environmentally extended multiregion input‐output (EEMRIO) databases are used to quantify numerous environmental pressures and impacts from a consumption perspective. However, for targeted communication with decision makers, ... -
Health benefits, ecological threats of low-carbon electricity
(Journal article; Peer reviewed, 2017)Stabilizing global temperature will require a shift to renewable or nuclear power from fossil power and the large-scale deployment of CO2 capture and storage (CCS) for remaining fossil fuel use. Non-climate co-benefits of ... -
Heat and mass transfer in gas-solid packed beds
(Doctoral theses at NTNU;2018:137, Doctoral thesis, 2018)The present thesis probes the heat and mass transfer phenomena in packed bed of particles. The gap in literature for realistically packed dense particle packings is explored, following which a new methodology to study ... -
