Ultrafast carrier and lattice dynamics in semiconductor and metal nanocrystals

This thesis presents an experimental study of the time-resolved optical response of three different nanoscale systems: CdSe and PbSe quantum dots, and silver triangular nanoplates. The first part of the thesis is devoted to the understanding of the effects ...

Alexandre Sarrasin (1895-1976) et l'esthétique de l'ingénieur

Philippe Mivelaz

Alexandre Sarrasin (1895-1976) studied at Zürich Federal Swiss Institute of Technology (ETH) from 1913 to 1918. Despite First World War's conflicts surrounding the neutral Switzerland, the intellectual climate inside ETH was cosmopolitan and liberal. As un ...

Eikonal approximation in AdS/CFT: resumming the gravitational loop expansion

We derive an eikonal approximation to high energy interactions in Anti-de Sitter spacetime, by generalizing a position space derivation of the eikonal amplitude in flat space. We are able to resum, in terms of a generalized phase shift, ladder and cross la ...

The strongly-interacting light Higgs

Riccardo Rattazzi

We develop a simple description of models where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Gold stone boson. Two parameters broadly characterize these models: m(p), th ...

On the possibility of extending the Noro-Frenkel generalized law of correspondent states to nonisotropic patchy interactions

Giuseppe Foffi, Francesco Sciortino

Colloidal systems (and protein solutions) are often characterized by attractive interactions whose ranges are much smaller than the particle size. When this is the case and the interaction is spherical, systems obey a generalized law of correspondent state ...

Formation of Boronate Ester Polymers with Efficient Intrastrand Charge Transfer Transitions by Three-Component Reactions

Rosario Scopelliti, Ursula Röthlisberger, Kay Severin, Michele Cascella, Nicolas Christinat, Emmanuel Croisier

The three-component reaction of aryl boronic acids with 1,2,4,5-tetrahydroxybenzene and 1,2-bis(4-pyridyl)ethylene or 4,4-bipyridine leads to the formation of dark-purple boronate ester polymers. Crystallographic analyses show that the polymer strands have ...

Photodissociation of Alkyl Iodides in Helium Nanodroplets III: Recombination

Marcel Drabbels, Andreas Braun

The recombination of fragments resulting from the photodissociation of (fluorinated) alkyl iodides in helium nanodroplets at a wavelength of 266 nm has been investigated by means of ion imaging techniques. It is found that in the case of CH3I an appreciabl ...

Involvement of a Golgi-resident GPI-anchored protein in maintenance of the Golgi structure

Françoise Gisou van der Goot Grunberg, Xuan Li

The Golgi apparatus consists of a series of flattened cisternal membranes that are aligned in parallel to form stacks. Cytosolic-oriented Golgi-associated proteins have been identified that may coordinate or maintain the Golgi architecture. Here, we descri ...

Stochastic phase oscillators and circadian bioluminescence recordings

Felix Naef, Jacques Rougemont

Cultured circadian oscillators from peripheral tissues were recently shown to be both cell-autonomous and self-sustained. Therefore, the dominant cause for amplitude reduction observed in bioluminescence recordings of cultured fibroblasts is desynchronizat ...
