The paper entitled Small Size Effects in Open and Closed Systems: What Can We Learn from Ideal Gases about Systems with Interacting Particles? has been published in the Journal of Chemical Physics. Small systems have higher surface area-to-volume ratios than macroscopic systems. One consequence of this is that properties of small systems can be dependent on the …

The paper entitled Choked liquid flow in nozzles: Crossover from heterogeneous to homogeneous cavitation and insensitivity to depressurization rate has been published in Chemical Engineering Science. The critical mass flow rate is the maximum flow rate that can pass through a constrained geometry such as a nozzle. In the paper linked to above, we demonstrate that a …
From the 1st of August 2021, I start to work full time as a Professor at the Department of Chemistry at NTNU. The position is within equilibrium and non-equilibrium thermodynamics, and was formally announced more than one year ago. There were many excellent applicants, and I feel very proud to end up on the top of …
The EFCE Excellence award in Thermodynamics and Transport properties is awarded every second year to an excellent PhD thesis. In 2021, it was awarded to my former PhD student and present collaborator, Dr. Ailo Aasen. The judging committee of EFCE’s Thermodynamics and Transport Properties Working Party was highly complementary of the technical quality of Aasen’s work, which …
The paper entitled Theory and simulation of shock waves: Entropy production and energy conversion has been published in Phys. Rev. E. In the paper, we have investigated shock waves by use of nonequilibrium thermodynamics and nonequilibrium molecular dynamics (NEMD) simulations. We have also considered a shock wave as a surface of discontinuity and computed the entropy production …

The paper entitled Chemical Potential Differences in the Macroscopic Limit from Fluctuations in Small Systems has been accepted for publication in the Journal of Chemical Information and Modeling. The paper is the first in the PhD of Vilde Bråten, and written also together with Ass. Prof. S. K. Schnell. The paper presents a new method for computing chemical …
