Stabilization of electrodynamic bearings with active magnetic dampers

Electrodynamic Bearings (EDBs) are a kind of passive magnetic bearings that exploits the interaction between the induced eddy currents in a conductor and a magnetic field to provide re-storing forces. They have been regarded as an appealing alternative to ...

Kinetic model for calcium sulfate alpha-hemihydrate produced hydrothermally from gypsum formed by flue gas desulfurization

Xuerun Li

Modeling of the kinetics of the synthesis process for calcium sulfate alpha-hemihydrate from gypsum formed by flue gas desulfurization (FGD) is important to produce high-performance products with minimal costs and production cycles under hydrothermal condi ...

Solid heat-expandable polylactide-poly(methyl methacrylate) foam precursors prepared by immersion in liquid carbon dioxide

Jan-Anders Edvin Maansson, John Christopher Plummer, Yonghoon Yoon

Solid heat-expandable foam precursors were prepared by impregnating melt-blended poly(d,l-lactide) (PDLLA)-poly(methyl methacrylate) (PMMA) blends with liquid carbon dioxide (CO2). The phase behavior of these blends was strongly dependent on the processing ...

Nucleation of Silicon Nanoparticles in Amorphous Silicon Dioxide Matrices

Simone Meloni

In this contribution I summarize our research on the formation of nanoparticles embedded in a-SiO2-x matrices. In particular, I focus on the Si diffusion in SiO2-x matrices, and amorphous-to-crystalline phase transition in Si nanoparticles embedded in SiO2 ...

On the stability of traffic perimeter control in two-region urban cities

Nikolaos Geroliminis, Jack Haddad

In this paper, stability analysis of traffic control for two-region urban cities is treated. It is known in control theory that optimality does not imply stability. If the optimal control is applied in a heavily congested system with high demand, traffic c ...

Arrested demixing opens route to bigels

Giuseppe Foffi, Nicolas Dorsaz, Francesco Varrato, Maxim Belushkin

Understanding and, ultimately, controlling the properties of amorphous materials is one of the key goals of material science. Among the different amorphous structures, a very important role is played by colloidal gels. It has been only recently understood ...

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 ...

Phase behaviour of the symmetric binary mixture from Thermodynamic Perturbation Theory

Giuseppe Foffi, Nicolas Dorsaz

We study the phase behaviour of symmetric binary mixtures of hard core Yukawa (HCY) particles via thermodynamic perturbation theory (TPT). We show that all the topologies of phase diagram reported for the symmetric binary mixtures are correctly reproduced ...

Signatures of unstable semiclassical trajectories in tunneling

Sergey Sibiryakov

It was found recently that processes of multidimensional tunneling are generally described at high energies by unstable semiclassical trajectories. We study two observational signatures related to the instability of trajectories. First, we find an addition ...
