Nowadays most of the Conservation Science is related to diagnostic and only a few methods are available for the conservation and restoration of Cultural Heritage. We pioneered most of the innovative methodologies available for conservation using tools borrowed from Nano-Science. Micelles, microemul-sions, nanoparticles, and gels are used in a large number of applications. All these systems constitute a new platform for Conservation of Cultural Heritage and are characterized by scale lengths below 100 nm in one or more dimensions. With illustrative examples, we will report on the applications of these innovative methodologies in recent restoration workshops.

It is solid at normal room temperature yet melts easily in the mouth leaving a pleasant and distinct taste. In this talk I will shortly present the history of chocolate from his early discovery, a cocoa plantation established by the Maya in the south part of Yucatan about 600 AD, to its introduction in Europe, in Spain in 1520. The processing of the cocoa beans from their harvesting, to their fermentation, drying, storage, roasting, cracking and grinding will be illustrated to show how complex some of the processes and analysis are. Then we will have a look at the science of chocolate, and find out about the latest research into the possible health effects of its consumption. Lastly, we'll explore the somewhat controversial question of why chocolate make us feel so good. Chocolate contains more than 300 known chemicals. Scientists have been working on isolating specific chemicals and chemical combinations which may explain some of the pleasurable effects of consuming chocolate. Caffeine is the most well known of these chemical ingredients, and while it's present in chocolate, it can only be found in small quantities. Theobromine, a weak stimulant, is also present, in slightly higher amounts. The combination of these two chemicals (and possibly others) may provide the "lift" that chocolate eaters experience. Phenylethylamine is also found in chocolate. It's related to amphetamines, which are strong stimulants. All of these stimulants increase the activity of neurotransmitters (brain chemicals) in parts of the brain that control our ability to pay attention and stay alert. I will discuss the effect of chocolate on health and in particular as antidepressant, for cardiovascular diseases and on its controversial addiction. The talk will contain piece of movies and of course a delicious degustation… in order to convince everybody that chocolate is indeed the food of the Gods! Bon appétit! {{:decola_iyc.png?300}} */ /* __December 12 2011:__ **ISIS Mini-Symposium** 14h00 **Cristina NEVADO** (Switzerland), **Olivier BAUDOIN** (France), and **Paul KNOCHEL** (Germany) on //"Catalyse"// {{aff_mini_catalysis.png?300}} */ /* __January 16 2012:__ **Conference ISIS** 16h30, Prof. **Marat YUSUPOV**, //"Crystal structures of bacterial and yeast ribosomes"//, Institut de Genetique et de Biologie Moleculaire et Cellulaire, Université de Strasbourg (France) **Abstract**: The ribosome is the large ribonucleoprotein particle that synthesizes proteins in all cells, using messenger RNA as the template and aminoacyl-transfer RNAs as substrates. Ribosomes from bacteria consist of a large (50S) and a small (30S) subunit, which together compose the 2.5-megadalton 70S ribosome; their eukaryotic counterparts are the 60S and 40S subunits and the 80S ribosome. The ribosome selects aminoacylated tRNA as specified by the mRNA and catalyzes the formation of peptide bonds. The crystal structure of the yeast 80S ribosome reveals the higher complexity of eukaryotic ribosomes, which are 40% larger than their bacterial counterparts. The eukaryotic 80S and bacterial 70S ribosome shares 34 common proteins and eukaryotic ribosome has additional 45 unique proteins and bacterial ribosome has 22 additional unique proteins. The majority of eukaryotic specific elements of ribosomal RNA and proteins are located on the periphery of the conserved core. Our crystals capture the ribosome in two different conformations which are believed to reflect intermediate states in course of mRNA and tRNA translocation. Structural rearrangements of the ribosome in the tRNA binding step have been studied on bacterial ribosome model. Discrimination of tRNA on the ribosome occurs in two consecutive steps: initial selection and proofreading. We propose a proofreading mechanism based on comparison of crystal structures of the 70S ribosome with cognate or near-cognate tRNA. We have shown involvement of tales of ribosomal proteins in stabilization of correct tRNA on the ribosome. We suggest that proofreading begins with stabilization of tRNA anticodon loop with involvement of magnesium ions, following by stabilization of elbow region and accommodation of the acceptor end in the peptidyl transferase center. {{:yusupov_conf.jpg?400}} */ __January 31 2012:__ **Conference ISIS** 16h30, Prof. **Antoine GEORGES**, //"Quantum Matter with Strong Correlations: from hot superconductors to cold atoms"//, Collège de France and Ecole Polytechnique (France) About 25 years have passed since the spectacular discovery of superconductors with “high” transition temperatures by Bednorz and Müller (Nobel prize, 1987). Yet, the broad class of materials to which these superconducting copper-oxides belong continues to fascinate physicists and chemists. Indeed, solid-state chemistry, new elaboration techniques, and improved experimental probes have provided us with many families of transition-metal oxides with remarkable electronic properties, such as metal-insulator transitions, large magnetoresistance or thermoelectric power. Furthermore, these materials raise deep fundamental physics questions. They challenge the very basic principles on which conventional theories of the solid-state are based because, in those materials, the motion of each electron is strongly correlated with that of all the others. New frontiers are also opening up, which bring together condensed-matter physics and quantum optics. ``Artificial crystals’’ made of ultra-cold atoms trapped by laser beams can be engineered with a remarkable level of controllability, and allow for the study of quantum physics in previously unexplored regimes. {{:george_conf.png?400}} ===== Rencontres ISIS ===== |[[http://www-isis.u-strasbg.fr/doc/rencontres1405.pdf|{{http://www-isis.u-strasbg.fr/images/rencontres1405.png?nolink}}]] |May 14th, 2008, Rencontre ISIS 17h00, Prof. **Martin Karplus** //"Motion : a hallmark of life.
