Correlating electrochemical properties with structure on the mesoscale

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 ...

Potential of a plasma bound between two biased walls

Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Julien Stanislas Pierre Dominski

An analytical study is presented for an one-dimensional, steady-state plasma bound between two perfectly absorbing walls that are biased with respect to each other. Starting from a description of the plasma sheaths formed at both walls, an expression relat ...

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 ...

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 ...

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]) ...

Quasi-static monotonic and cyclic tests on composite spandrels

Katrin Beyer, Alessandro Dazio

In modern unreinforced masonry (URM) walls, the vertical piers are connected at the storey levels by reinforced concrete (RC) ring beams or RC slabs. Particularly, in the outer walls, the spandrel element also includes a masonry spandrel on top of the RC b ...

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 ...

MULTI-BUNCH EFFECT OF RESISTIVEWALL IN THE CLIC BDS

Nicolas Frank Mounet, Raphaël Mutzner

Wake fields in the CLIC Beam Delivery System (BDS) can cause severe single or multi-bunch effects leading to luminosity loss. The main contributors in the BDS are geometric and resistive wall wake fields of the collimators and resistive wall wakes of the b ...

Computation of accommodation coefficients and the use of velocity correlation profiles in molecular dynamics simulations

Peter Spijker

For understanding the behavior of a gas close to a channel wall it is important to model the gas-wall interactions as detailed as possible. When using molecular dynamics simulations these interactions can be modeled explicitly, but the computations are tim ...
