Read more about the reindeer nose and how it can help us studying energy efficiency
Reindeer (Rangifer tarandus) have evolved elaborate nasal turbinate structures that are perfused via a complex vascular network. These are subject to thermoregulatory control, shifting between heat conservation and dissipation, according to the animal’s needs. The three-dimensional design of the turbinate structures is essential in the sense that they determine the efficiency with which heat and
New Release: Nanothermodynamics – General Theory
The world of small systems challenges standard knowledge. Can we use classical thermodynamics? The answer to that is no. The book discusses how Terrill Hill developed the field of nanothermodynamics, which applies perfectly well also to small systems, to address this problem. He introduced an ensemble of replicas of the small system and showed that
Frontiers and NTNU form open access publishing agreement
Announcement from Frontiers, posted on April 2, 2020 The Norwegian University of Science and Technology (NTNU), supports their authors in publishing open access. As part of this support, NTNU will cover Article Processing Charges (APCs) for eligible articles centrally for their eligible authors. As part of the UNIT Open Access Publishing Framework Agreement, NTNU will
Read about stretching and breaking of PEO nanofibres in the last article from Eivind Bering and Astrid de Wijn
Read the last manuscript from Eivind Bering and Astrid de Wijn in Soft Matter here: DOI: 10.1039/D0SM00089B Title: Stretching and breaking of PEO nanofibres. A classical force field and ab-initio simulation study Abstract: The burgeoning development of nanotechnology is allowing us to construct more and more nanoscale systems in the real world that used to
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
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
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

Most Downloaded Fluid Phase Equilibria Articles
Congratulations to Magnus Aa. Gjennestad and Øivind Wilhelmsen ! Their article on “Thermodynamic stability of droplets, bubbles and thick films in open and closed pores” is one of the most downloaded Fluid Phase Equilibria articles in the last 90 days. This is a major accomplishment! Their article is available in the volume 505 from 1.
Read about the heat effects in Lithium ion batteries in the last publication from Gunnarshaug et al. here
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
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
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
Publication about “Predicting Resistivity and Permeability of Porous Media Using Minkowski Functionals”
Per Arne Slotte, Carl Fredrik Berg and Hamid Hosseinzade Khanamiri released their last publication in “Transport in Porous Media”. volume 130, no.3, December 2019.

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