Surface structure of nickel oxide layers on a Rh(111) surface
The formation of nickel oxide nanolayers by oxidizing Ni overlayers on Rh(111) has been investigated and their structures are reported as a function of the nickel coverage and oxygen pressure. Scanning tunneling microscopy (STM), low-energy electron diffra ...
Elsevier2013Spectral characterization of fully phase-matched high harmonics generated in a hollow waveguide for free-electron laser seeding
Christoph Peter Hauri, Fernando Ardana Lamas
We present a bright and coherent soft x-ray source based on high harmonic generation delivering up to 10(10) photons per second centered at 120 eV within an 80 eV bandwidth. The source profits from fully phase-matched harmonic generation in an unmodulated ...
Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2013Effect of the spectral properties of TiO2, Cu, TiO2/Cu sputtered films on the bacterial inactivation under low intensity actinic light
César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche
Bacterial inactivation by TiO2, Cu and TiO2/Cu DC-magnetron sputtered thin films was systematically investigated in the dark and under low intensity visible/actinic light. Low intensity actinic light led to a fast 6log10 (complete) bacterial inactivation w ...
Elsevier2012Fabrication of membranes and microchannels in low-temperature co-fired ceramic (LTCC) substrate using novel water-based sacrificial carbon pastes
In this work, 3D structuration of LTCC (low-temperature co-fired ceramic) for microfluidics was studied, using two novel sacrificial carbon paste compositions. These pastes are based on graphite with a water-soluble vehicle consisting of polyvinylpyrrolido ...
Elsevier2012Interface Investigations on Titanium Nitride Bilayer Systems
Nanocomposite coatings composed of two phases with atomically sharp phase boundaries, show interesting mechanical properties. These properties are often originating from their high interface to volume ratio. Composites of nanocrystalline titanium nitride ( ...
EPFL2012Three-Dimensional Electron Realm in VSe2 by Soft-X-Ray Photoelectron Spectroscopy: Origin of Charge-Density Waves
Thorsten Schmitt, Vladimir N. Strocov, Helmuth Berger, Xiaoqiang Wang
The resolution of angle-resolved photoelectron spectroscopy (ARPES) in three-dimensional (3D) momentum k is fundamentally limited by ill defined surface-perpendicular wave vector k(perpendicular to) associated with the finite photoelectron mean free path. ...
Amer Physical Soc2012Effect of Crystallographic Phase (β vs. γ) and Surface Area on Gas Phase Nitroarene Hydrogenation Over Mo2N and Au/Mo2N
Lioubov Kiwi, Vincent Laporte, Fernando Cardenas Lizana, Daniel André Samuel Lamey
The catalytic action of Mo2N and Au/Mo2N has been assessed in the selective gas phase hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN). The nitrides were synthesised via temperature programmed treatment of MoO3 in H-2 + N-2 and Au i ...
Springer US2012Electronic and Magnetic Resonant Inelastic X-ray Study of Cuprates
More than twenty five years have passed since the discovery of the first copper oxide based superconductor La2-xBaxCuO4 in 1986, and the intriguing physics of cuprates superconductors continues to fascinate and challenge scientists from all over the world. ...
EPFL2012ARPES Studies of Cuprate and Pnictide Superconductors
Since the discovery of cuprate superconductors in 1986, the subject of high temperature superconductivity has triggered a lot of scientific activity. Despite enormous efforts, the origin of high-temperature superconductivity is still the subject of intense ...
EPFL2012Electronic structure of single crystal UPd3, UGe2, and USb2 from hard X-ray and angle-resolved photoelectron spectroscopy
Electronic structure of single crystal UPd3, UGe2, and USb2 has been measured from hard X-ray photoelectron spectroscopy (HAXPES) with 7.6 keV photons at the European Synchrotron Radiation Facility (ESRF). Lower photon energy angle-resolved photoelectron s ...
