Active Turbulence of Self-Propelled Particles with Hydrodynamic Interactions
Skjesol, Petter Kjønstad (Master thesis, 2021)I denne avhandlingen presenter vi simuleringer av et 2-dimensjonelt (2D) aktivt system bestående av polare, selvdrevne partikler med langtrekkende hydrodynamiske vekselvirkninger. Dette er en modell for mikroorganismer som ... -
Biological lipid nanotubes and their potential role in evolution
Gözen, Irep; Dommersnes, Paul Gunnar (Peer reviewed; Journal article, 2020)The membrane of cells and organelles are highly deformable fluid interfaces, and can take on a multitude of shapes. One distinctive and particularly interesting property of biological membranes is their ability to from ... -

Complex flows in active and driven granular matter: a study of turbulent and intermittent dynamics
Roman, Etien Martinez (Doktoravhandlinger ved NTNU;2022:174, Doctoral thesis, 2022)Turbulence and intermittency are manifestations of non-linear dynamics that have central influence in transport mechanisms in fluids. These phenomena have been mainly studied in inertial flows, but this situation is recently ... -
Dynamic renormalization group of interfaces in scalar active matter
Christiansen, Øystein Fruseth (Master thesis, 2022)Biologiske systemer er ofte bygget opp av partikler som er kapable til å transformere kjemisk energy som er lagret i systemet til arbeid eller felles bevegelse. Slike systemer kalles aktive systemer og kan eksemplifiseres ... -
Electric stress-induced slip lines in jammed particle monolayers
Mikkelsen, Alexander; Dommersnes, Paul Gunnar; Fossum, Jon Otto (Peer reviewed; Journal article, 2016)Drops fully covered by particles, so called Pickering emulsion drops, are used to stabilize emulsions and are ideal templates for producing particles and advanced capsules. Recent studies show how electrohydrodynamic ... -
Electric-stress-induced Slip Lines in Jammed Particle Monolayers
Mikkelsen, Alexander; Dommersnes, Paul Gunnar; Fossum, Jon Otto (Journal article; Peer reviewed, 2016)Drops fully covered by particles, so called Pickering emulsion drops, are used to stabilize emulsions and are ideal templates for producing particles and advanced capsules. Recent studies show how electrohydrodynamic ... -
Electro-hydrodynamic propulsion of counter-rotating Pickering drops
Dommersnes, Paul Gunnar; Mikkelsen, Alexander; Fossum, Jon Otto (Journal article; Peer reviewed, 2016)Insulating particles or drops suspended in carrier liquids may start to rotate with a constant frequency when subjected to a uniform DC electric field. This is known as the Quincke rotation electro-hydrodynamic instability. ... -
Epidemic spreading in an active matter model
Øvstetun, Silje (Master thesis, 2020)I denne masteroppgaven har vi studert hvordan et virus kan spre seg i en befolkning med mennesker. Vi har gjort dette ved å lage en numerisk modell hvor vi kan teste hvordan ulike tiltak og restriksjoner påviker antall ... -
Exogenous lysophospholipids with large head groups perturb clathrin-mediated endocytosis
Ailte, Ieva; Lingelem, Anne Berit Dyve; Kvalvaag, Audun Sverre Myrset; Kavaliauskiene, Simona; Brech, Andreas; Koster, Gerbrand; Dommersnes, Paul Gunnar; Bergan, Jonas; Skotland, Tore; Sandvig, Kirsten (Journal article; Peer reviewed, 2017)In this study, we have investigated how clathrin-dependent endocytosis is affected by exogenously added lysophospholipids (LPLs). Addition of LPLs with large head groups strongly inhibits transferrin (Tf ) endocytosis in ... -
Intermittent dynamics in dense active matter
Stubberud, Edvard (Master thesis, 2020)Aktiv-materie fysikk bruker teoretiske modeller for å forstå og forklare kollektiv oppførsel for livsformer av alle størrelser, fra svømmende bakterier til dyr i flokk. Dette studiet utforsker et system med selvdrivende ... -
Investigating Boundary Effects on Metachronal Wave Formation and Fluid Flow in Model Carpets of Motile Cilia
Osmundsen, Veslemøy (Master thesis, 2023)I denne avhandlingen presenterer vi simuleringer av avgrensede, 2-dimensjonale(2D) modell-systemer av biologiske, bevegelige cilia. Dynamikken man finner i store populasjoner av bevegelige cilia i biologiske systemer, er ... -
Jamming-flow transitions of confined self-propelled rods
Thorvik, Marius (Master thesis, 2021)Denne oppgaven presenterer en numerisk undersøkelse av egenskapene til en hybridmodell av selvdrevne stav-aktige partikler i 2D som vekselvirker via apolar vinkeltilpasning og myk frastøtning. Såkalte aktive partikler ... -
