Περίληψη : Όλοι γερνάμε. Και ίσως είναι το καλύτερο που μπορεί να μας συμβεί. Αλλά δεν ξέρουμε ακριβώς γιατί. Ξέρουμε όμως ότι με την ηλικία, η πιθανότητα να νοσήσουμε αυξάνεται δραματικά. Πρόσφατα δεδομένα φαίνεται να φωτίζουν κάποιες από τις κυρίαρχες αιτίες της γήρανσης. Και μαζί με αυτήν, της αυξημένης συχνότητας εμφάνισης ασθενειών με τη πάροδο του χρόνου.
Σε αντίθεση με τα περισσότερα μακρομόρια, το πυρηνικό DNA (η απαρχή του RNA και των πρωτεϊνών) είναι αναντικατάστατο. Και ενώ η χημική του σύσταση είναι εξαιρετικά ασταθής, το DNA οφείλει να διατηρηθεί αναλλοίωτο καθόλη τη διάρκεια της ζωής του κυττάρου. Κυρίως επειδή η γενετική πληροφορία πρέπει να κληρονομηθεί αυτούσια στα θυγατρικά κύτταρα. Σήμερα, γνωρίζουμε ότι αλλοιώσεις στο DNA επιφέρουν δραματικές αλλαγές στη λειτουργία ζωτικών διεργασιών, όπως η μεταγραφή και ο αναδιπλασιασμός του DNA. Ίσως, το τελευταίο να εξηγεί γιατί βλάβες σε πρωτεΐνες που συμμετέχουν στον ίδιο επιδιορθωτικό μηχανισμό γενετικών βλαβών να σχετίζονται με σύνδρομα που εμφανίζουν πρώιμη γήρανση ή αυξημένη συχνότητα εμφάνιση καρκίνου.
Η ομιλία μου θα αντλήσει πρόσφατα στοιχεία από τον άνθρωπο και τον ποντικό για τη σχέση των βλαβών στο DNA με τη γήρανση και τον καρκίνο.

ABSTRACT
Computational Materials Science undergoes a change of paradigm - while it was a tool to explain experimentally found phenomena and to support the understanding of materials and processes in materials, we can now employ its predictive power to design and to tailor new materials.
In my presentation I will first illustrate how joint experimental-theoretical research can perform, with examples on highly doped transition metal oxide nanoparticles. In the second part, I will extend the subject on metal-organic frameworks and other framework materials.

Novel optical beams: an experimentalist's perspective

Abstract
Recently a plethora of optical beams with non trivial amplitude and phase distributions have been introduced. In a collection containing only the, classical now, Bessel beams an increasing number of new members like the Airy and the radially symmetrical Airy, Mathieu and Weber beams have been added.
These novel optical beams propagate in curved trajectories and resist to diffraction or dispersion. Therefore, they are able to self-heal and bypass obstacles, advantages that make them exiting for applications ranging from materials processing to telecommunications.
On the other hand, the generation of these wavepackets is not trivial. Their complexity challenges our current state of the art techniques for wavefront shaping, and has urged us to exploit, among others, unconventional approaches like the use of optical aberrations.
The talk will focus on the exciting ongoing quest of materializing these novel optical wavepackets at higher intensities and boarder spectral range, and their usage to generate tailored filaments, light bullets, abruptly auto focusing waves and telecommunication links.

Non-linear Mechanics applied to Molecular Dynamics: understanding chemical reactions

Abstract
Nonlinear mechanics is now a mature science. It has successfully been applied to a diversity of fields that show complex behaviors. As far as Chemistry is concerned nonlinear mechanics has helped us to comprehend concepts such as Transition State, Activated Complex, and Reaction Pathways, which are the cornerstones in statistical theories of chemical reactions. For first time these concepts have been put on a rigorous mathematical ground and extended to polyatomic molecules with multivariable Potential Energy Surfaces and complicated topologies. The application of the theory of nonlinear mechanics to molecular dynamics had as a consequence to elevate the stage on which chemical reactions are performed from the configuration manifold to its cotangent bundle (phase space). The latter revealed that time invariant phase space structures, such as Periodic Orbits, Tori, Normally Hyperbolic Invariant Manifolds (NHIMs) and their (un)stable manifolds are the mathematical objects that should be associated with the transition state and reaction pathways. It has been demonstrated that bifurcations of periodic orbits, such as the center-saddle, define reaction paths in phase space, which can not be predicted from the landscape of the potential functions.
I shall present classical and exact quantum dynamical calculations for realistic cases of small triatomic molecules spectroscopically studied, and model systems for large biological
molecules, which show that nonlinear mechanics is ineluctable for understanding how chemical bonds break/form in elementary chemical reactions and the necessity of moving from structural chemistry to phase space chemistry.
