Organometallic ruthenium(II)-arene (RA) antitumour compounds of the general type [Ru(II)(η6-arene)(X)2(pta)], RA-pta, and [Ru(II)(η6-arene)X(en)], RA-en, (X=leaving group; pta=1,3,5-triaza-7-phosphaadamantane, en=ethylenediamine) have been investigated com ...
In this thesis work, we report scanning near-field optical photoluminescence spectroscopy measurements with at best 200 nm spatial resolution performed on disordered semiconductor V-groove AlGaAs/GaAs quantum wires. In order to interpret the results of the ...
The photodissociation of (fluorinated) alkyl iodides in helium nanodroplets at a wavelength of 266 nm has been investigated by means of ion imaging techniques. It is found that a significant fraction of the created fragments escapes from the helium droplet ...
Using a first-principles approach, we calculate Si 2p core-level shifts for spherosiloxane H8Si8O12 clusters chemisorbed on Si(001). A chemisorption mechanism that preserves the cage structure of the clusters is assumed. The resulting relaxed surface struc ...
In order to investigate the dramatic enhancement of the oxidation rate of semiconductor materials, promoted by an alkali-metal overlayer, we exposed a GaAs(110) surface covered by a monolayer of Cs to oxygen, observing the photoemission spectra of As 2p, G ...
We calculate binding energies of shallow acceptors in GaAs/Ga1-xAlxAs quantum wells (QWs) for varying well widths. Variational calculations are performed in the framework of a multiband effective-mass theory, which accounts for the mixing between heavy and ...
Ru(II) and Os(II) p-cymene dichloride complexes with either a pta (1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) or [pta-Me]Cl ligand which exhibit anticancer activity were prepd. and characterized by 1H and 31P NMR spectroscopy and mass spectrometry. Thr ...
