Segregation in a quasi-stationary avalanche on an inclined conveyor-belt.

We have carried out laboratory experiments to determine the internal structure of segregating dense granular avalanches and test the recent theoretical predictions of the existence of breaking size-segregation waves [Thornton & Gray, 2008]. Measurements we ...

Correlating electrochemical properties with structure on the mesoscale

Raffaella Buonsanti

The integration of inorg. nanocrystals as building units into mesoscale architectures yields materials whose structure is controllable on at., nano, and meso length scales providing a foundation for understanding how system-level functional properties emer ...

Macroscopic Theory of Charged Domain Walls in Ferroelectrics

Maxim Gureev

This thesis consists of a theoretical analysis of charged domain walls in ferroelectrics based on Landau theory and the theory of semiconductors. First, the internal structure of a 180-degree charged domain wall is considered. It is shown that different re ...

Effect of load distribution and variable depth on shear resistance of slender beams without stirrups

Aurelio Muttoni, Miguel Fernández Ruiz

The shear resistance of elements without stirrups has mainly been investigated by test setups involving simply supported beams of constant thickness subjected to one- or two-point loading, and most of the formulas included in codes have been adjusted using ...

High Aspect Ratio Microstructures

Jérôme Béguin

The goal of this project is to find a substrate and parameters that allow the realisation of hight aspect ratio microstructures. We tried three substrates (Ti, Cr and Si), two photoresist thicknesses (50 and 100 [m]), two focalisation points (8 and 12 [m]) ...

Tokamak SOL fluid simulations with self-consistent boundary conditions at the magnetic presheath edge

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

Fluid codes simulating the dynamics of magnetized plasmas with field lines terminating on the device vessel require boundary conditions that are consistent with the plasma-wall transition region. When the magnetic field strikes the wall at an oblique angle ...

Atomic Force Microscopy Stiffness Tomography on Living Arabidopsis thaliana Cells Reveals the Mechanical Properties of Surface and Deep Cell-Wall Layers during Growth

Giovanni Dietler, Sandor Kasas, Charles Roduit, Christian Fankhauser

Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and in living cells. Here, we used ato ...

Assembly of Ligand-Stripped Nanocrystals into Precisely Controlled Mesoporous Architectures

Raffaella Buonsanti

The properties of mesoporous materials hinge on control of their compn., pore dimensions, wall thickness, and the size and shape of the crystallite building units. We create ordered mesoporous materials in which all of these parameters are independently co ...

Hole Staggering Effect on the Cooling Performance of Narrow Impingement Channels

Peter Ott, Alexandros Terzis, Guillaume Wagner

This study examines experimentally the cooling performance of integrally cast impingement cooling channels which provide increased heat transfer area compared to traditional impingement configurations. For the evaluation of the heat transfer coefficient, t ...
