Optical absorption properties of metal-organic frameworks: solid stateversusmolecular perspective

Berend Smit, Anne-Clémence Corminboeuf, Ivano Tavernelli, Maria Fumanal Quintana

The vast chemical space of metal and ligand combinations in Transition Metal Complexes (TMCs) gives rise to a rich variety of electronic excited states with local and non-local character such as intra-ligand (IL), metal-centered (MC), metal-to-ligand (MLCT ...

Heat-transfer at the interface between a metal and a non-metal: influence of ultra-thin interlayers, interface chemistry and atomic order

Maïté Blank

The Thermal Boundary Conductance (TBC) at the interface between metals and dielectrics is of key importance for heat transport in structures heterogeneous on a scale from 100 µm downwards. In this thesis the TBC of a large number of metal/dielectric couple ...

Varying the metal to ethacrynic acid ratio in ruthenium(ii)/osmium(ii)-p-cymene conjugates

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Emilia Paunescu, Mylène Soudani

Following the identification of a ruthenium(II)-arene complex with an ethacrynic acid-modified imidazole ligand, which inhibits glutathione transferase (GST) and is cytotoxic to chemo-resistant cancer cells, a series of structurally related ruthenium(II)- ...

Suppressing Nucleation in Metal–Organic Chemical Vapor Deposition of MoS2

Andras Kis, Dmitrii Unuchek, Dmitry Ovchinnikov, Davide Deiana, Hokwon Kim

Toward the large-area deposition of MoS2 layers, we employ metal–organic precursors of Mo and S for a facile and reproducible van der Waals epitaxy on c-plane sapphire. Exposing c-sapphire substrates to alkali metal halide salts such as KI or NaCl together ...

Photo-transformation of pedogenic humic acid and consequences for Cd(II), Cu(II) and Pb(II) speciation and bioavailability to green microalga

Pascal Miéville

Humic substances (HS) play key role in toxic metal binding and protecting aquatic microorganisms from metal-induced stress. Any environmental changes that could alter HS concentration and reactivity can be expected to modify metal complexation and thus aff ...

Two-Dimensional Metal-Organic Networks as a New Class of Electrocatalysts

Benjamin Wurster

This thesis deals with the electrocatalytic properties of two-dimensional metal organic coordination networks (2D-MOCNs) self-assembled on electrode surfaces and catalytic activity of 2D-MOCNs is demonstrated for the first time. The low-coordinated metal c ...

Fatigue and cyclic creep of replicated microcellular aluminium

Andreas Mortensen, Frédéric Diologent, Sébastien Philippe Soubielle

The cyclic behaviour of 400 mu m pore size replicated aluminium foam is assessed in tension-tension fatigue with a stress ratio equal to 0.1, keeping the load amplitude constant, for relative density values comprised between 0.175 and 0.220. The number of ...

Micro-, meso- and macrostructures in replicated microcellular aluminium

Yves Conde

This thesis is focused on the properties of microcellular aluminium, produced by replication processing, at the micro, meso and macrostructural level. The replication process is based on the infiltration of a porous sodium chloride (NaCl) perform with molt ...

Uniaxial deformation of microcellular metals: model systems and simplified analysis

Andreas Mortensen, Frédéric Diologent, Jean-François Despois, Yves Conde, Randoald Müller, Sébastien Philippe Soubielle

Microcellular aluminium can be produced by a process known as replication; this involves the infiltration of a packed bed of NaCl particles which are subsequently leached after metal solidification. The resulting material features a uniform distribution of ...

Age-Hardening Response of Replicated Microcellular Al-4.5%Cu

Andreas Mortensen, Yves Conde

We study the response to age hardening of Al-4.5%Cu replicated foams with 75 and 400 pm cell sizes and with varying relative densities. The 400 mu m cell size foams have a similar behavior to the bulk alloy, whereas the 75 pm cell size foams with relative ...
