Revisiting the Limit Behaviour of ``El Botellon"

Jean-Yves Le Boudec

Emergent phenomena occur due to the pattern of non-linear and distributed local interactions between the elements of a system over time. An example of such phenomena is the spontaneous self-organisation of drinking parties in the squares of cities in Spain ...

Phase separation in binary eye lens protein mixtures

Nicolas Dorsaz, Giuseppe Foffi

Liquid–liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of t ...

Supercooling of nanoscale Ga drops with controlled impurity levels

Anna Fontcuberta i Morral, Emanuele Uccelli

We use in situ observations by variable temperature transmission electron microscopy on Ga drops at the tips of GaAs nanowires to investigate the phase behavior of nanoscale Ga. Experiments on pure Ga drops are compared with drops containing well-defined l ...

Free energy methods in coupled electron ion Monte Carlo

Elisa Liberatore

Recent progress in simulation methodologies and in computer power allow first-principles simulations of condensed systems with Born–Oppenheimer electronic energies obtained by quantum Monte Carlo methods. Computing free energies and therefore getting a qua ...

Spinodal surface of a free energy model for eye lens protein mixtures: Relevance for cataracts

Nicolas Dorsaz, Giuseppe Foffi

We studied the phase behavior of a model binary mixture of eye lens crystallin proteins using first-order thermodynamic perturbation theory. The instability boundary, or spinodal surface, was found to be very sensitive to the strength of the attraction bet ...

Superfluid to Bose-Glass Transition in a 1D Weakly Interacting Bose Gas

Vincenzo Savona, Luca Fontanesi

We study the one-dimensional Bose gas in spatially correlated disorder at zero temperature, using an extended density-phase Bogoliubov method. We analyze, in particular, the decay of the one-body density matrix and the behavior of the Bogoliubov excitation ...

Micro- and macrosegregation of a peritectic Au-Fe alloy during Bridgman solidification

Michel Rappaz, Denis Favez

In jewelry manufacturing, joining dissimilar materials is usually achieved by soldering or brazing, but these techniques have several disadvantages as compared for example with laser welding. In this last case, however, it is necessary to have a thorough u ...

Solidification Behaviour Of PLLA/nHA Nanocomposites

Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

PLLA crystallization rates increase with nHA content owing to increased nucleation, which compensates a decrease in spherulite growth rate, G, at 100 to 130 °C, and to suppression of the twin peak in G(T) seen in pure PLLA, linked to a transition from the ...

Modeling two-phase flows on moving domains

Matthias Preisig

Mudflows are catastrophic events that cause immense damage to infrastructure and life every year. Local authorities have been trying to mitigate the risk by zoning regulations as well as by building protection structures for many years. These measures have ...

First-principles study of the effect of nitrogen vacancies on the decomposition pattern in cubic Ti1-xAlxN1-y

Alireza Karimi

The effect of nitrogen substoichiometry on the isostructural phase stabilities of the cubic Ti1-xAlxN1-y system has been investigated using first-principles calculations. The preferred isostructural decomposition pattern in these metastable solid solutions ...
