"Solid Catalysts by molecular design"

We will present concepts directing to prepare solid catalysts with well-defined active sites, going from hybrid organic-inorganic mesoporous materials to zeolites and to metals. We will show that besides the nature of the active sites, the presence of confined spaces introduces additional activity and selectivity’s to the catalysts.

The presence of dispersion forces, within the confined space, further stabilize the reaction transition state, decreasing the activation enthalpy for the reaction.
We will also show how to prepare supported single metal atoms and subnanometric metal clusters correlating catalysts behaviour with the electronic properties.

Finally, it will be presented how the knowledge acquired has allowed us to design and prepare catalysts that are now operating industrially.

Professor Carlos Duarte

In recognition to his contributions to Oceanography and to address environmental problems

Prof. Carlos Duarte is a world-wide leader in multiple branches of biological oceanography and marine ecology. He is probably the most versatile aquatic ecologist of his generation: he works from the tropics to polar ecosystems, from macrophytes to microbes, from coastal systems to open ocean gyres using all type of approaches. His pioneering work on seagrasses and other vegetated systems eventually lead – in collaboration with different UN agencies - to the development of “blue carbon” strategies for climate change mitigation and adaptation, which has provided a strong impetus to the conservation of vegetated coastal ecosystems adopted by hundreds of programs and projects around the world. Prof. Duarte received many awards to scientific excellence, and inspired hundreds of research programs, being author of 660 peer-reviewed papers and more than 60 books or book chapters. His research is characterized by independence, creativity, serendipity and interdisciplinary linking, as well as the capacity to organize and collaborate with large interdisciplinary teams.

"Hidden Forests: the role of vegetated coastal habitat in the Earth System"

Vegetated coastal habitats, including seagrass and macroalgal beds, mangrove forests and salt-marshes, form highly productive ecosystems, but their contribution to the global carbon budget remains overlooked and these forests remain "hidden" in representations of the global carbon budget. Despite being confined to a narrow belt around the shoreline of the world's oceans, where they cover less than 7 million Km2, vegetated coastal habitats support about 10% of the global marine net primary production, and generate a large organic carbon surplus, of about 40 % of their NPP, which is either buried in sediments within these habitats or exported away. Large, 10-fold uncertainties in the area covered by vegetated coastal habitats, along with variability about carbon flux estimates, result in a 10-fold bracket around the estimates of their contribution to organic carbon sequestration in sediments and the deep sea from 73 Tg C year-1 to 866 Tg C year-1, representing up to 1/3 of the biological CO2 removal by marine biota. Up to 1/2 of this carbon sequestration occurs in sink reservoirs (sediments or the deep sea) beyond these habitats. The organic carbon exported that does not reach depositional sites subsidizes the metabolism of heterotrophic organisms. In addition to their significant contribution to organic carbon production and sequestration, vegetated coastal habitats contribute as much to carbonate accumulation as coral reefs do. Whereas globally-relevant, the magnitude of global carbon fluxes supported by salt-marsh, mangrove, seagrass and macroalgal habitats is declining due to rapid habitat loss, contributing to loss of CO2 sequestration, storage capacity and carbon subsidies. Incorporating the carbon fluxes v egetated coastal habitats support into depictions of the carbon budget of the global ocean and its perturbations will improve current representations of the carbon budget of the global ocean.

"Failure Mechanisms of Sandwich Structure"

Sandwich structures consisting of strong and stiff facings and light weight cores offer improved stiffness and strength to weight ratios compared to monolithic materials. Under flexural loading the facings carry almost all of the bending, while the core takes the shear loading and helps to stabilize the facings. Facing materials include metals and fiber reinforced composites. The latter are being used in advanced applications due to the large strength-to-weight ratio. The core materials mainly include honeycombs, cellular foams and wood. In the present seminar the failure behavior of composite sandwich beams subjected to three- and four-point bending will be presented. The beams were made of unidirectional carbon/epoxy facings and various core materials including PVC closed-cell foams, a polyurethane foam and an aluminum honeycomb. Various failure modes including facing wrinkling, indentation failure and core failure were observed and compared with analytical predictions. It was established that the initiation, propagation and interaction of failure modes depend on the type of loading, constituent material properties and geometrical dimensions.

Blaise Pascal Medal in Physics

Professor Peter Hänggi

In recognition of his pioneering and lasting contributions on the beneficial role of fluctuations in statistical mechanics in and away from thermal equilibrium

Professor Peter Hänggi presents a most visible flagship that changed our perception of noise. He has developed the theoretical tools to study classical and quantum Stochastic Resonance by which ambient noise is used to boost weak signals/information rather than hampering those. He also is the founder of the area of "Brownian motors", i.e. Brownian noise fueled devices, which in combination with non-equilibrium forces shuttle, separate and direct cargo on micro- and nanoscales. In addition, he is well known for his outstanding pivotal developments to relativistic thermodynamics and to the foundations of quantum thermodynamics. His oeuvre is extremely broad (over 600 publications), which is acknowledged internationally via his election to several scientific academies, being recipient of several prizes and him holding 10 doctor honoris causa degrees, among scores of other prestigious accolades.

"The ring of Brownian motion: The good, the bad and some simply silly"

Since the turn of the 20-th century Brownian noise has continuously disclosed a rich variety of phenomena in and around physics. The understanding of this jittering motion of suspended microscopic particles has undoubtedly helped to reinforce and substantiate those pillars on which the basic modern physical theories are resting: Its formal description provided the key to great achievements in statistical mechanics, the foundations of quantum mechanics and also astrophysical phenomena, to name but a few. -- Brownian motion determines the rate-limiting step in most transport phenomena via escape events that help to overcome obstructing bottlenecks, does trigger firing events of neurons and in ion channels or, more generally, induces oscillatory dynamics in excitable media. Recent progress of Brownian motion theory involves (i) the description of relativistic Brownian motion and its impact for relativistic thermodynamics, or (ii) its role for fluctuation theorems and symmetry relations that constitute the pivot of those recent developments for nonequilibrium thermodynamics beyond the linear response regime.

Although noise commonly is hold as an enemy of order, it in fact also can be of constructive influence. The phenomena of Stochastic Resonance and Brownian motors present two such archetypes wherein random Brownian dynamics together with unbiased nonequilibrium forces beneficially cooperate in enhancing detection and/or in facilitating directed transmission of information. The applications range from innovative information processing devices in physics, chemistry, and in physical biology to new hardware for medical rehabilitation. Particularly, those additional non-equilibrium disturbances enable the rectification of haphazard Brownian noise so that quantum and classical objects can be directed along on a priori designed routes (i.e. Brownian motors). Despite its thrilling manifold successes Brownian motion is, nonetheless, not the ''Theory of Everything'', as is revealed by some more doubtful applications. We conclude with an outlook of future prospects and unsolved issues.
