MICROSYMPOSIA

Chairperson: Gilberto Artioli, University of Milan

The microsymposium wishes to present recent and innovative application of synchrotron- and laboratory-based diffraction techniques in the structural and physical characterization of inorganic materials.
Topics to be included: resonant scattering, diffraction in non-ambient conditions, microstructure, time-resolved and in-situ studies, etc.

Plenary lecture:
Lawrence Margulies (Risoe National Laboratory, Denmark)
   "Diffraction studies on microstructure development"

Chairperson: Adriana Zagari, University of Naples

In the last few years the rate of biological structure determination has risen explosively.
Furthermore, extensive studies of larger molecules or macromolecule assemblies, such as myosin, virus and ribosome, have unveiled sophisticated biological mechanisms.
The contribution of synchrotron radiation has been essential to this success.

Plenary lecture:
Jens Nyborg (Institute of Molecular and Structural Biology, Univ. of Aarhus, Denmark)
   "Protein biosynthesis, recent structures of the ribosome and some of its associated factors"

Chairperson: Gianluca Cascarano, CNR Bari

This microsymposium is devoted to results and advances in structural crystallography. Contributions involving the application of non conventional radiation sources and/or novel investigation techniques will be presented.

Plenary lecture:
Andrew Fitch (European Synchrotron Radiation Facility, Grenoble, France)
   "Use of synchrotron radiation in crystal structure solution: state of the art and perspectives"

Chairperson: Nicola Lovergine, University of Lecce

This year Crystal Growth Micro-Symposium will focus on the results of experimental and theoretical studies of fundamental mechanisms driving the growth of crystals at the microscopic (i.e., atomic and nano-scale) level. These mechanisms are essential in understanding the physical-chemical properties and evolution of solid-vapour and solid-liquid interfaces during growth, as of as-grown crystals. Several "in-situ" and "ex-situ" probes (such as AFM/STM, XSR, RHEED, RAS, etc.) can be employed today by crystal growers to investigate the interfaces at both the atomic and nano-scale. The use of molecular dynamics methods allow detailed simulation of crystal growth by self-assembling of constituent atoms/molecules, helping to bridge the gap between experiments and theories. These studies show their importance not only for materials science, but also for technological applications.

Plenary lecture:
Wolfang Richter (Technical University of Berlin, Germany)
   "Probing Epitaxial Growth on a Microscopic Scale"

Chairperson: Giovanni Stefani Univ. Roma 3, Roma, Italy

The aim of the microsymposium is to present recent studies performed with synchrotron radiation in fields different from crystallography in order to cover the full application scientific spectrum opened to synchrotron radiation.
In this microsymposium only contributed papers will be presented.

Chairpersons:
   Maddalena Pedio TASC-INFM, Trieste, Italy
   and Calogero Natoli, LNF-INFN, Frascati, Italy

The aim of the microsymposium is to provide a state of the art description of Synchrotron Radiation spectroscopic methods and techniques and their use in structural and morphological studies of different systems, from the biology to multilayer and nanostructures
