Magnetic impurities in solids cause manifold changes in their macroscopic properties, such as anomalous low temperature resistance due to Kondo screening, reduction of the superconducting transition temperature due to local suppression of the order paramet ...
Elsevier2009Search for corannulene (C20H10) in the Red Rectangle
Polycyclic Aromatic Hydrocarbons (PAHs) are widely accepted as the carriers of the Aromatic Infrared Bands (AIBs), but an unambiguous identification of any specific interstellar PAH is still missing. For polar PAHs, pure rotational transitions can be used ...
Blackwell Publishing Ltd, Oxford2009Structural, 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 ...
2009Mechanical spectroscopy of 18-carat AuCuPd white gold alloys
Daniele Mari, Robert Schaller, Iva Tkalcec Vâju, John Hennig
The mechanical loss and dynamic modulus temperature spectra of two 18-carat white gold alloys, Au58%Cu24%Pd18% without (grade A) and with alloying additions (grade B), were measured in the 400-1000 K temperature range. A peak interpreted as a Zener relaxat ...
2009Structural analysis of ultrafast extended x-ray absorption fine structure with subpicometer spatial resolution : Application to spin crossover complexes
Majed Chergui, Wojciech Gawelda, Van Thai Pham, Renske Marjan van der Veen
We present a novel analysis of time-resolved extended x-ray absorption fine structure (EXAFS) spectra based on the fitting of the experimental transients obtained from optical pump/x-ray probe experiments. We apply it to the analysis of picosecond EXAFS da ...
2009The effect of molecular vibrations and surface structure on the chemisorption of methane on platinum
In this thesis, I report state-resolved measurements of the chemisorption probability of CH4 on Pt(111) and Pt(110)-(1×2) for several rovibrationally excited states (2ν3, ν1+ν4, and 2ν2+ν4) in addition to the ground state. Measurements of the state resolve ...
EPFL2008Collisionally-assisted spectroscopy of water from 27000 to 34000 cm-1
Thomas Rizzo, Pavlo Maksyutenko, Maxim Grechko
We report here an experimental approach that enables measurement of weak transitions to a wide range of rovibrational levels of water in the energy region 27000-34200 cm-1. We have previously demonstrated the use of laser double-resonance overtone excitati ...
2008Robust model development and enhancement techniques for improved on-line spectroscopic monitoring of bioprocesses
The recent phenomenal growth of the field of biotechnology has contributed to a mounting pressure to improve process efficiency and productivity and to increase the quality and safety of end-products. This demand gave rise to the discipline of on-line biop ...
EPFL2008Ab Initio Prediction of the Emission Color in Phosphorescent Iridium(III) Complexes for OLEDs
We performed fully first principles quantum mechanical calculations of the ground and excited state geometries and harmonic vibrational frequencies of two prototype cationic Ir(III) complexes showing high emission quantum efficiencies. Thanks to recent the ...
2008Experimental and theoretical investigations of the thermodynamic stability of Ba-C-60 and K-C-60 compound clusters
A novel experimental set-up was used to study superstable (magic) Ba-C-60 and K-C-60 compound clusters. The most stable systems observed cannot be rationalized by simple electronic or by geometrical shell filling arguments. Annealing the clusters past the ...
