Features of proteolytic properties of tetraphenylporphyrin complex with lanthanide group metals

Demetallation of metalloporphyrin molecules is one of the essential degradation reactions in photosynthesis. The effect of metalloporphyrin nature on removal of central metals from tetraphenylporphyrin complexes based on lanthanide group metals (Dy, Er, Lu ...

Spin Excitations in a 4f-3d Heterodimer on MgO

Harald Brune, François Patthey, Fabio Donati, Christian Wäckerlin, Aparajita Singha, Donat Fabian Natterer

We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic compound of a lanthanide and a transition metal atom. The dimers are adsorbed on ultrathin MgO(100) films grown on Ag(100). New for 4f elements, we detect ...

Reversible Segregation of Nickel from Perovskite-type Oxides - Applications in Energy Processes

Patrick Simon Steiger

In this thesis, Ni catalysts derived from perovskite-type metal oxides (PMO, general formula ABO3, A=lanthanide or earth alkaline element, B=transition metal) are investigated as a potential class of materials, which are able to overcome thechallenges of c ...

Yttrium zinc tin oxide high voltage thin film transistors

Danick Briand, Herbert Shea, Alexis Pierre Henri Marette

We demonstrate that doping the semiconductor zinc tin oxide (ZTO) with yttrium leads to a high-voltage thin film transistor (HVTFT) with enhanced switching performance. Adding 5% yttrium leads to an increase in the on-off ratio from 40 to 1000 at an operat ...

Enhanced piezoelectric properties of c-axis textured aluminium scandium nitride thin films with high scandium content: influence of intrinsic stress and sputtering parameters

Paul Muralt, Silviu Cosmin Sandu, Gabriel Christmann, Stefan Mertin, Clemens Benedict Nyffeler, Fazel Parsapour, Vladimir Pashchenko

Aluminium scandium nitride (ASN) exhibits a largely enhanced piezoelectric response as compared to aluminium nitride (AlN), which makes it an upcoming piezoelectric material for use in next generation RF filters, sensors, actuators and energy harvesting de ...

Reduction of a Cerium(III) Siloxide Complex To Afford a Quadruple-Decker Arene-Bridged Cerium(II) Sandwich

Rosario Scopelliti, Marinella Mazzanti, Rory Patrick Kelly

Organometallic multi-decker sandwich complexes containing f-elements remain rare, despite their attractive magnetic and electronic properties. The reduction of the Ce-III siloxide complex, [KCeL4] (1; L = OSi(OtBu)(3)), with excess potassium in a THF/tolue ...

Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters

Aparajita Singha

This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...

Nucleophilic Reactivity of a Nitride-Bridged Diuranium(IV) Complex: CO2 and CS2 Functionalization

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain, Marta Falcone

Thermolysis of the nitride-bridged diuranium(IV) complex Cs{(-N)U(OSi((OBu)-Bu-t)(3))(3)} (1) showed that the bridging nitride behaves as a strong nucleophile, promoting N-C bond formation by siloxide ligand fragmentation to yield an imido-bridged sil ...
