The 2017 eSSENCE meeting on “Multiscale modelling of materials and molecules”

The 2017 eSSENCE meeting on
“Multiscale modelling of materials and molecules”
will take place 12-14 June in Uppsala

The eSSENCE e-science program arranges a materials modelling meeting
with our sister program SeRC and other e-science actors, June 12-14 2017.
We expect an interesting mix of method/model development and applications.
The meeting, including all meals, is free of charge.

How to give a scientific presentation at conferences

Dear colleagues,

As you may be aware, the Structural Chemistry program is currently hosting Professor Konstantin Neyman from the University of Barcelona as a Visiting Professor. His visit has been made possible by a generous grant awarded by Uppsala University.

Professor Neyman is a theoretical chemist and an ICREA professor in the Department of Materials Science and Physical Chemistry at the University of Barcelona. He is an international authority in computational materials science and nanostructured materials.

We invite you to a small reception in Professor Neyman’s honor on Friday 17 February at 16.00 in the lunchroom on floor 4, at the south end of Ångström (Å14167), directly followed by a lecture 16.30-17.15 in Polhemsalen, on the topic of

Professor Konstantin Neyman, University of Barcelona
Modelling catalytic nanomaterials
– as simple as possible, but not simpler

The speaker is a Faculty of Science and Technology Visiting Professor of Uppsala University for Winter 2016-17. He is also an ICREA Research Professor at the Department of Materials Science and Physical Chemistry of the University of Barcelona. He is an international authority in computational materials science, and nanostructured materials in particular.

In heterogeneous catalysts, active metal components are present as nano-aggregates of thousands of atoms. Due to their sizes, these nano-aggregates remain inaccessible to first-principles quantum-mechanical calculations. However, such species can be represented rather realistically by computationally tractable smaller metal nanoparticles (NPs) whose surface sites marginally change the reactivity with increasing particle size [1]. I will illustrate this for Pd catalysts [2, 3] as well as for the building of active sites on Pt/ceria catalysts [4-6]. I will show that employment of common slab models, which neglect the nanoscopic effects in these and similar systems, can lead to severe misrepresentation of the surface reactivity.

Dedicated NP models, as proposed by us, expose a variety of active sites, the structure and geometric flexibility of which notably better match those of the sites present in technical catalysts.

Poster Prize: Multiscale Modelling of Materials and Molecules 2016

Meysam, Vanessa, and KerstiThe “Best poster” prize, “Multiscale Modelling of Materials and Molecules 2016” held on 7-9 June in Uppsala, was awarded to Vanessa Quaranta (poster title “Construction of a DFT-Based Neural Network Potential for the Water-Zinc Oxide Interface”)


eSSENCE-SeRC: Materials & Molecules Meeting 2016

Multiscale Modelling of Materials and Molecules 2016, the latest in an annual series of meetings arranged as part of the the eSSENCE national e-science programme, will take place at the Ångström Laboratory in Uppsala between Tuesday 7th June and Thursday 9th June, lunch-to-lunch. We use the term “materials” in a broad sense, to include solids, liquids, and molecules, and interfaces between them. We will discuss both method & model development and interesting applications.

This year, we will have the European dimension as a special theme for one of the sessions. With the support of VR, Sweden will become a member of CECAM, with Uppsala University acting as the co-ordinating institution, and the opportunities for Swedish researchers arising from this will be discussed. Furthermore, the latest version of the European Roadmap for Modelling drafted by the European Materials Modelling Council will be presented and debated.


The meeting is free of charge, including all meals. Day 1 will start at 13.00 with oral sessions in the afternoon, with a poster session followed by a buffet dinner in the evening. Day 2 will include a full programme of oral presentations, plus the conference dinner; the meeting will end after the morning oral sessions at lunchtime on Day 3. We have reserved single and  double rooms at two hotels, with prices from 495 SEK per person per night (see details under Hotels). 

Invited keynote speakers are:

Georg Kresse (University of Vienna, Austria)
Prof. Kresse is the main developer of the VASP program, which is one of the world’s most
widely used electronic structure code for materials modelling (more than 2500 groups
from academia and industry).

Peter Kusalik (University of Calgary, Canada)
Prof. Kusalik is an expert on the dynamics of water and ice,  interfaces and crystallization.
He will speak about collective molecular phenomena and models for nucleation and growth,
on the theme “Simulation of crystallization: Past, present and future”.

Dominic Tildesley (CECAM, EPFL Lausanne, Switzerland)
Prof. Tildesley is the Director of CECAM and an expert on computer simulation
of liquids. He will speak about CECAM and challenges of coarse-grained simulations
that go beyond electrons and atoms.

Klaus Koch (University of Stellenbosch, South Africa)
South Africa is the world’s largest supplier of Platinum Group Metals (PGMs) and
Prof. Koch in an expert in PGM chemistry. He is an experimentalist with a
great interest in simulations and will discuss the challenges involved in trying to
understand the nature of the PGMs, and the challenges involved in meeting the
needs of the PGM industry.
