NICAS Colloquium

23Mar2017 12:00 - 13:00

Event

We are very pleased to announce the next edition of the NICAS Colloquium on Thursday 23 March from 12.00 to 13.00 hrs. The colloquium will take place in conference room B of the Atelier Building (Hobbemastraat 22, Amsterdam).

Chair

The chair of this colloquium will be Tom Callewaert (TU Delft), PhD candidate with the Imaging Physics research group in Delft.

Lambert van Eijck - Neutrons imaging: a gentle probe to study the interior of art objects

Neutrons easily penetrate metals and yet are particularly sensitive to light elements: in many ways neutrons can be considered complementary to X-rays. We will present the current neutron imaging and tomography capabilities available in Delft, which we consider very suited to investigate the interior of art objects, non-destructively. With this presentation we hope to discuss with you the possibilities of neutrons in cultural heritage.

Lambert van Eijck is assistant professor at the TU Delft in the group Neutron and Positron Methods in Materials. He has recently built a novel neutron powder diffractometer Pearl at the research reactor in Delft for sustainable energy materials. One of the new projects he works on with Katia Pappas, Jeroen Plomp and Zhou Zhou is the new First Imaging Station Holland, FISH, for neutron tomography.

Ariana Torres Knoop - Investigating the mechanical properties of oil binders: a molecular dynamics approach

Oil paints have been used for many centuries and, although each painting is unique, at a molecular level they all share the same basic composition: they are coloured pigment particles bound in a drying oil medium.  The properties of drying oils as binders arise from their constitution of mostly unsaturated fatty acids, highly susceptible to oxidation. The drying of oil medium is a chemical drying which involves the cross-linking of oil molecules by an oxidative process. In this research we want to explore the properties of oil binders using molecular simulations.  For that we (1) generate a molecular model of the oil binder, (2) cross-link the oil molecules using chemically based rules and (3)  investigate the effect of different conditions (e.g temperature, solvents and different types of pigments) in the mechanical properties of the polymerised (cured) oil binder.

Ariana Torres Knoop  first interest in computational modeling started during her bachelor in physics in the National University of Mexico (UNAM). After finishing her physics degree in 2010, she decided to pursue a personal and professional adventure and moved to Europe to study a joint master program between the ENS Lyon and the UvA, focus on statistical physics and atomic scale modeling. She started her PhD in the Molecular Simulation group of the UvA shortly after finishing her master and successfully finished in 2016 (cum laude). She joined the PREDAGIO project, under the supervision of Piet Iedema, in June 2016.
