Heat transfer monitoring between quenched high-temperature superconducting coated conductors and liquid nitrogen

High-temperature superconducting coated conductors (HTS-CCs) are good candidates for resistive superconducting fault current limiter (RSFCL) applications. However, the high current density they can carry and their low thermal diffusivity expose them to the ...

Time-strip visualization and thermo-hydrodynamics in a Closed Loop Pulsating Heat Pipe

John Richard Thome, Navid Borhani, Giulia Spinato, Brian Paul D'Entremont

New trends in the microprocessor industry are leading not only to miniaturization and integration but also to increases in power dissipation rates which now require advanced cooling solutions to prevent thermal damage to the devices. Pulsating heat pipes ( ...

Matrix-product-operator approach to the nonequilibrium steady state of driven-dissipative quantum arrays

Vincenzo Savona, Hugo Pierre Alexandre Flayac, Eduardo Carlo Mascarenhas Moraes

We develop a numerical procedure to efficiently model the nonequilibrium steady state of one-dimensional arrays of open quantum systems based on a matrix-product operator ansatz for the density matrix. The procedure searches for the null eigenvalue of the ...

Self-heating hydrogel for mechanically-controlled drug release

Mohamadreza Nassajian Moghadam

Due to our active lifestyle, knee cartilage is at risk for focal defects. Unfortunately, the native healing properties of the articular cartilage are very limited. New strategies to treat cartilage defects are then developed such as the local delivery of g ...

Josephson Tunneling at the Atomic Scale

Berthold Jäck

The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate ...

A non-local continuum damage approach to model dynamic crack branching

Jean-François Molinari, Nicolas Richart, Cyprien Wolff

Dynamic crack branching instabilities in a brittle material are studied numerically by using a non-local damage model. PMMA is taken as our model brittle material. The simulated crack patterns, crack velocities and dissipated energies, compare favorably to ...

Dissipation processes in the insulating skyrmion compound Cu2OSeO3

Ivica Zivkovic, Helmuth Berger

We present a detailed study of the phase diagram surrounding the skyrmion lattice (SkL) phase of Cu2OSe2O3 using high-precision magnetic ac susceptibility measurements. An extensive investigation of transition dynamics around the SkL phase using the imagin ...

Energy dissipation in concentrated monodisperse colloidal suspensions of silica particles in polyethylene glycol

Véronique Michaud, Mathieu Soutrenon

Highly concentrated colloidal suspensions exhibit a discontinuous shear-thickening behaviour. The transition from a low to a high viscosity state is associated to a large energy dissipation. This effect could find applications in structural damping while t ...

Air Entrainment and Energy Dissipation on Gabion Stepped Weirs

Davide Wüthrich

In the last three decades the design of stepped spillways regained some interest because of their suitability with new construction methods including gabion placement. In this study, the hydraulic performances of gabion stepped weirs were investigated expe ...

The role of energy dissipation of polymeric scaffolds in the mechanobiological modulation of chondrogenic expression

Dominique Pioletti, Philippe Abdel Sayed, Ulrike Kettenberger, Salim Elias Darwiche

Mechanical stimulation has been proposed to induce chondrogenesis in cell-seeded scaffold. However, the effects of mechanical stimuli on engineered cartilage may vary substantially between different scaffolds. This advocates for the need to identify an ove ...
