This thesis work focuses on impact and diffusion processes as well as equilibrium positions of a metal deposited on a surface. The metal is deposited in the form of clusters containing n atoms in a controlled way. Gold or silver clusters cations (Au+n and ...
Butene hydrogenation activity is intimately connected with the occupied and unoccupied electronic states of gold active site. We prepare well-defined Au(III) sites in IRMOF-3 structure, and tuned the metal density-of-states by replacing the substituent gro ...
Ce mémoire, réalisé sous mandat de la bibliothèque de l’Ecole Polytechnique Fédérale de Lausanne (EPFL), fait état de la publication en Open Access aujourd’hui. Il couvre ainsi les disciplines scientifiques présentes dans l’institution, plus particulièreme ...
Low intrinsic toxicity, high solubility, and stability are important and necessary features of gold nanoparticles to be used in the biomedical field. In this context, charged nanoparticles proved to be very versatile, and among them charged mixed-monolayer ...
We present a novel technique for heterogeneous integration using gold filled Through Silicon Vias (TSV) and thermocompression bond bumps formed in a single fabrication step, using gold nanoparticles dispensed by inkjet printing. Gold-filled TSV arrays (12 ...
Background: Total (i.e. free + sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analyt ...
A new BODIPY-phosphane was synthesized and proved to be a versatile tool for imaging organometallic complexes. It also led to easy access to a new family of theranostics, featuring gold, ruthenium and osmium complexes. The compounds' cytotoxicity was teste ...
The stability of Au/Al2O3 in the continuous gas phase (423 K) hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN) has been investigated over an inlet H-2/p-CNB = 4-390, i.e. from close to stoichiometry to H2 far in excess. The catalyst ...
Cultured fibroblasts adhere to extracellular substrates by means of cell-matrix adhesions that are assembled in a hierarchical way, thereby gaining in protein complexity and size. Here we asked how restricting the size of cell-matrix adhesions affects cell ...
A novel two-step method was developed to prep. gold nanoparticles on boron-doped diamond (BDD) electrode. It consisted of sputter deposition of max. 15 equiv monolayers of gold, followed by a heat treatment at 400-600 Deg in air. The as-sputtered gold depo ...
