Read how inconsistencies are removed by properly incorporating the curvature dependence of the surface tension of the mixture into classical nucleation theory for multicomponent systems

By PoreLab30 January, 2020Publications

This is the last publication from Ailo Aasen , David Reguera and Øivind Wilhelmsen available under the PHYSICAL REVIEW LETTERS 124, Issue 4. The study of nucleation in fluid mixtures exposes challenges beyond those of pure systems. A striking example is homogeneous condensation in highly surface-active water alcohol mixtures, where classical nucleation theory yields an

Major Boost to Open Access Publishing as Norway Signs New National Agreement

By PoreLab30 January, 2020Publications

A landmark national agreement has been signed on January 28, 2020 by the Norwegian Directorate for ICT and Joint Services in Higher Education & Research (Unit) and the leading open access publisher Frontiers. The terms of the agreement will simplify the publishing process for Norwegian researchers who publish in Frontiers’ journals. The deal includes a

Read about the heat effects in Lithium ion batteries in the last publication from Gunnarshaug et al. here

By PoreLab9 January, 2020Publications

Lithium ion batteries are used to store and produce electric energy. During the charging- and discharging processes, net heat is released or adsorbed in the battery. Temperature is one of the most important factors for battery ageing. In this study we are seeking a fundamental understanding of one of the heat effects, the reversible heat

A new paper explores the stability of droplets, bubbles and films in pores

By PoreLab1 January, 2020Publications

PhD candidate Magnus Aa. Gjennestad (PoreLab/NTNU) and Senior Researcher/Professor Øivind Wilhelmsen (SINTEF/PoreLab/NTNU) recently published the paper “Thermodynamic stability of droplets, bubbles and thick films in open and closed pores” in Fluid Phase Equilibria. In this work, a thermodynamic description was developed to study the stability of droplets, bubbles and films of water in a pore. For a particular set of conditions,

The flying chain strikes again

By PoreLab28 November, 2019Publications

Do you remember the YouTube video from Marcel and the relevant publications on the flying chain? Well, the flying chain strikes again! The group has produced a new theoretical model for explaining the phenomenon that included the effects of fluctuations along the chain length. This model, backed up by experiments and numerical simulations, successfully predicted

New article from Marcel Moura et al. on “Connectivity enhancement due to film flow in porous media”

By PoreLab25 September, 2019Publications

Thin liquid films and capillary bridges can effectively enhance the connectivity of a porous medium, making it possible for the drainage of apparently trapped liquid clusters. This drainage due to film flow was recently characterized in a paper published in Phys. Rev. Fluids by PoreLab researcher Marcel Moura and collaborators. The experimental work has shown
