Martin’s paper published in Nature Communications

Martin’s paper together with Gabriele, Fabio, Silvio and Angelos has been published in Nature Communications!

In this paper we investigate pre-critical fluctuations and what they can tell us about the heterogeneous nucleation event. Pre-critical fluctuations are the earliest occurrences of crystalline clusters in a supercooled liquid and thus readily probed in simulations such as molecular dynamics. We find that they can tell us which polymorph will form but they are not trivially indicative (as often assumed) of the nucleation enhancement. This also means that the commonly applied heterogeneous classical nucleation theory makes an error when comparing heterogeneous and homogeneous nucleation events where different polymorphs have formed. As a side, in this work we also find a simple recipe of avoiding stacking-disorder in hetergeneous ice nucleation during the nucleation stage.

Martin’s paper accepted in JCP!

Martin’s paper together with Laurent, Ming, Gabriele, Andrea and Angelos has been published in JCP Communications! In this work we studied wetting of water droplets on a substrate. With the help of metadynamics we have uncovered that for cutoffs that are more than commonplace in the MD community (2-3 sigma) the underlying free energy profile of wetting can exhibit metastable wetting states. Those states are not only unphysical but they can also be very hard to detect and could therefore corrupt computational results and interpretations. Our results show that a cutoff should not be treated as a fitting parameter in the development of force fields since the underlying physics can be inherently different and thus one needs to use long-range versions or very large cutoffs if one wants to be absolutely sure.

Philipp’s and Martin’s paper published in PRB!

Philipp’s and Martin’s paper was published in Physical Review B! In this article they computed the ice nucleation ability of numerous model hydroxylated substrates with diverse OH group arrangements. For the substrates considered, they find that neither the symmetry of the OH patterns nor the similarity between a substrate and ice correlate well with the IN ability. Instead, they find that the OH density and the substrate-water interaction strength are useful descriptors of a material’s IN ability. This insight allows the rationalization of ice nucleation ability across a wide range of materials, and can aid the search and design of novel potent ice nucleators in the future.

New Humboldt-Fellow in the group

Julia was successful in her application for an Alexander von Humboldt Fellowship and will continue her work in the ICE group with the Feodor Lynen Fellowship of the Alexander von Humboldt Foundation as of 1st June 2020. Congratulations Julia!  


The ICE group is moving!

Angelos has accepted a position in Cambridge, and so the ICE group is moving! It’s going to be a reasonably slow multi-year phase transition. You can find more information in the official announcement. Congratulations, Angelos, and all the best for this exciting new opportunity!


Angelos appears on Clarivate’s ‘Highly Cited Researchers’ list!

Angelos has appeared on Clarivate’s ‘Highly Cited Researchers’ list for the second year in a row. Inclusion on the list is based on the number of recent publications that ranked in the top 1% by citations in a given field and year. For further details see: Congratulations!


Martin wins PhD prize!

Martin won the Marshall Stoneham prize for his PhD thesis on “Merging data-driven and computational methods to understand ice nucleation”. It is awarded by the Condensed Matter & Materials Physics Group (CMMP) for outstanding postgraduate research. Well done!


Fabian wins Best Poster prize at the MMM Hub conference!

The second annual Materials & Molecular Modelling (MMM) Hub Conference and User Meeting took place on 3-4 September. Many excellent talks demonstrated how the computational resources provided by the MMM Hub are used to tackle challenges in many areas of biological, chemical, and physical research. This was also illustrated by more than 50 posters, spanning […]


Science and sports in York

Last weekend, the ICE group gathered in York for the International Materials Simulation Workshop. Current and former members as well as collaborators talked about their recent projects and discussed how to tackle society’s big challenges, utilize advancements in methodology and make the most of fruitful collaborations. The meeting highlighted the diverse range of problems that […]


Triple Triathlon at Castle Howard in support of WaterAid

The ICE group will be participating in the Castle Triathlon series for the third year in a row. This time, three relays teams are going to compete at Castle Howard, near York, on 21 July. They will be swimming, cycling and running a combined distance of roughly 280 km! As part of the tradition, the […]


Open postdoc position (University of Manchester & ICE group)

A 2-year postdoc position is available in the Condensed Matter Physics group at the University of Manchester. The project will be carried out in collaboration with the ICE group and involves developing and applying theoretical models to understand the anomalous dielectric behaviour of water under confinement (Fumagalli et al. Science 360, 1339-1342, 2018). You can […]


Angelos sets world record at the London Marathon!

Angelos set a new world record for the “fastest marathon dressed as a scientist (male)” at this year’s London Marathon, finishing in 3:22:51. Congratulations! He also managed to raise more than £3000 in support of WaterAid, an international charity working to provide clean water and decent toilets to people all over the world. Many thanks […]


Welcome Julia!

The ICE group has a new member: Julia will be working on C-H activation at single-atom alloy catalysts. The project involves collaboration with Michail Stamatakis from UCL’s Department of Chemical Engineering. We hope you will have a pleasant and productive time in the ICE group!
