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.

Metal oxide thin films and nanostructures for energy-control and environmental applications

Abstract
Metal oxide thin films and nanostructures offer a wide range of potential applications including photocatalysis of organic pollutants,
"self-cleaning" surfaces and energy-efficient glass windows. We have applied simple, low-cost, environmental-friendly chemical techniques like sol-gel, spray pyrolysis, chemical vapour deposition and solution-based approaches to grow metal oxide thin films and nanostructures on glass, sapphire and plastic substrates. In particular, TiO2, TiO2:SiO2, ZnO, WO3 and VOx thin films and nanostructures have been grown by chemical methods on various substrates at relatively low temperatures and their structural,
morphological and optical properties were investigated. Moreover, the metal oxide samples were comprehensively studied with respect to their
photocatalytic efficiency regarding the degradation of stearic acid, their "self-cleaning" properties and electrochemical response. Several issues, including how growth parameters (precursor solution, temperature, growth time etc) affect metal oxide properties as well as the potential for technological applications, will be discussed.

Title:
"inuTech - Scientific computing solutions for research and the industry"
Speaker: Frank Vogel
Abstract:
Software packages on scientific computing can be used for the development of customized numerical turn-key solutions, either as stand-alone solvers or integrated with other products.
Its advantage is a flexible software design.
We will give examples on the development of applications and their integration in the researcher's working environment.
These may include mathematical and numerical modeling, complex simulations and mathematical optimization algorithms.

Abstract
I will discuss theoretical and experimental developments on the thermal transport in quasi - one dimensional quantum magnets. In particular, I will focus on open issues and controversial results related to the finite temperature transport of integrable models.
These singular systems are commonly used in the description of quasi-one dimensional materials. They are recently attracting interest in connection to experiments, following the discovery of unconventional thermal conductivity in quasi-1D magnetic materials.
