Modeling of amino acid nanofiltration by irreversible thermodynamics

Starting from the classical Kedem-Katchalsky model for filtration through membranes, we derive an equation to compute the permeate flux and the rejection of diprotic amino acid compounds. We discuss the influence of the pH, the viscosity and the feed conce ...

A theoretical study of disorder and decomposition in multinary nitrides hard coatings materials

Björn Alling

The development of multinary nitrides materials has revolutionised the hard coatings industry over the last 20 years. Especially important materials systems in this matter have been TiAlN and CrAlN which shows higher hardness, better oxidation resistance a ...

Granular Thermodynamics

Pedro Miguel Nunes Pereira de Almeida Reis

We present experimental evidence for a strong analogy between quasi‐2D uniform non‐equilibrium steady states (NESS) of excited granular materials and equilibrium thermodynamics. Under isochoric conditions we find that the structure of granular NESS, as mea ...

Structural, Spectroscopic, and Thermodynamic Consequences of Anti-Chelate Effect in Nine-Coordinate Lanthanide Podates

Jean-Claude Bünzli, Frédéric Gumy

The connection of three tridentate 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine binding units to an extended sulfurcontaining tripodal anchor in the ligand L9 yields nine-coordinate podates [Ln(L9)]3+ upon reaction with trivalent lanthanides, Ln(III). Struct ...

A mesoscale granular model for the mechanical behavior of alloys during solidification

Michel Rappaz, Stéphane Vernède, Jonathan Dantzig

We present a two-dimensional granular model for the mechanical behavior of an ensemble of globular grains during solidification. The grain structure is produced by a Voronoi tessellation based on an array of predefined nuclei. We consider the fluid flow ca ...

Linear Polynuclear Helicates as a Link between Discrete Supramolecular Complexes and Programmed Infinite Polymetallic Chains

Jean-Claude Bünzli, Frédéric Gumy, Michal Borkovec

The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DEMM, in condensed phase to such an extent that stable D3-symmetrical tetranuclear lanthanide-containing triplestranded ...

Conceptual Design of a Combined Cycle Power Plant Using Existing Gas Turbines

The main goal of this master is to define and analyse the best layout options for a combined cycle power plant. The gas turbines used for this combined cycle are known. Methods for power augmentation of the gas turbine are considered. Different layouts and ...

Sulfate attack and the role of internal carbonate on the formation of thaumasite

Thomas Schmidt

The sulfate attack is known to influence the durability of concrete. In general, significant damage due to sulfate interaction results in the structural breakdown of the concrete structure. However, the precipitation of thaumasite due to sulfate concentrat ...

Spin dependent thermoelectric effects in magnetic nanostructures

Santiago Serrano Guisan

The aim of this thesis work was to obtain a deeper understanding of spin-dependent transport by the study of mixed effects of heat and charge currents in magnetic nanostructures. Indeed, even thermodynamics establish a relationship between both currents, n ...
