Light-induced spin crossover in Fe(II)-based complexes: The full photocycle unraveled by ultrafast optical and X-ray spectroscopies

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Wojciech Gawelda, Cristina Consani

The light-induced spin and structure changes upon excitation of the singlet metal-to-ligand charge transfer (1MLCT) state of Fe(II)-polypyridine complexes are investigated in detail in the case of aqueous iron(II)-tris-bipyridine ([FeII(bpy)3]2+) by a comb ...

Carbon polymorphism in shocked meteorites: Evidence for new natural ultrahard phases

Philippe Gillet

A slice of the Havero meteorite which belongs to the ureilite class known to contain graphite and diamond was cut and then polished as a thin section using a diamond paste. We identified two carbonaceous areas which were standing out by more than 10 pm in ...

Exploratory synthesis and characterization of high nuclearity cluster-based compounds

Wendy Lee Queen

The purpose of the research was to find a simple synthesis with high nuclearity cluster-based compds. The two compds. that the research research was focused on are Cs5V14O42As8Cl (V14Cl) and Cs11Na3V15O36Cl6 (V15Cl). V14Cl and V15Cl were prepd. in a nitrog ...

X-ray-Induced Changes in Wettability

Giorgio Margaritondo

We observed that hard X-ray irradiation modifies the wettability of a variety of inorganic materials. The smooth surfaces of all tested inorganic materials (ZnO, p-Si, Al2O3, SrTiO3, TiN, ZnS, CuO, Ag2O, and Cr2O3) change during it-radiation to a state of ...

Transmission electron microscopy of Ca oxide nano- and microcrystals in alpha-tricalcium phosphate prepared by sintering of beta-tricalcium phosphate

Philippe Buffat, Elena Suvorova Buffat

Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to study the porous and non-porous alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2), alpha-TCP) prepared through a sintering procedure at 1200-1400 degrees C of beta-tricalcium phos ...

Optical description of solid-state dye-sensitized solar cells. I. Measurement of layer optical properties

Michael Graetzel, Henry Snaith

The efficiency of a photovoltaic device is limited by the portion of solar energy that can be captured. We discuss how to measure the optical properties of the various layers in solid-state dye-sensitized solar cells (SDSC). We use spectroscopic ellipsomet ...

Fabrication of Dendritic Gold Nanoparticles by Use of an Ionic Polymer Template

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

A facile method for the fabrication of dendritic gold nanoparticles (NPs) by use of an ionic polymer template has been developed. In situ generation of an imidazolium-based (cationic) polymer, poly[1-methyl-3-(4-vinylbenzyl)imidazolium], with AuCl4- counte ...

Nd:YAG laser joining between stainless steel and nickel-titanium shape memory alloys

Michel Rappaz, Aïcha Hessler-Wyser, Jonas Vannod

Nickel-Titanium (NiTi) shape memory alloys are often used in medical component devices, for instance as guide wires for neurological surgery applications. The manufacture of such devices becomes more and more challenging, especially considering the need to ...

Experimental observation using particle image velocimetry of inertial waves in a rotating fluid

Inertial waves generated by a small oscillating disk in a rotating water filled cylinder are observed by means of a corotating particle image velocimetry system. The wave takes place in a stationary conical wavepacket, whose angle aperture depends on the o ...
