Surface Micromachining of Polyureasilazane Based Ceramic-MEMS using SU-8 Micromolds

Jürgen Brugger, Vahid Fakhfouri, Sébastien Jiguet

We describe a novel surface micromachining process for the fabrication of ceramic-type MEMS devices, such as free-standing cantilevers, that is based on the use of high-aspect ratio micromolds of SU8 and aluminum as sacrificial layer. 250μm-high and 100-10 ...

Oxygen transfer and catalytic properties of nickel iron oxides for steam reforming of methane

Rudolf Paul Wilhelm Jozef Struis

Nickel iron oxide (NiFe2O4) has been tested as a combined catalyst precursor and oxygen transfer material for improved conversion of methane into syngas. Thermogravimetric measurements with simultaneous gas analysis have demonstrated the superior behavior ...

Dimeric Complexes of Lanthanide(III) Hexafluoroacetylacetonates with 4-Cyanopyridine N-Oxide: Syn thesis, Crystal Structure, Magnetic and Photoluminescent Properties

Jean-Claude Bünzli, Frédéric Gumy, Svetlana Eliseeva

A series of new mixed-ligand lanthanide complexes [Ln(hfa)3(4-cpyNO)]2 (Ln = SmIII-HoIII and TmIII; hfa- = hexafluoroacetylacetonate; 4-cpyNO = 4-cyanopyridine N-oxide) have been synthesised by treating the corresponding lanthanide hexafluoroacetylacetonat ...

Role of adsorbed NO in N2O decomposition over iron containing ZSM-5 catalysts at low temperatures

Albert Renken, Lioubov Kiwi

Transient response and temperature-programmed desorption/reaction (TPD/TPR) methods were used to study the formation of adsorbed NOx from N2O and its effect during N2O decomposition to O2 and N2 over FeZSM-5 catalysts at temperatures below 653 K. The react ...

New Method for Pavement Rutting Prediction

André-Gilles Dumont, Mehdi Ould Henia

In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...

Influence of the degradation of the organic matrix on the microscopic fracture behavior of trabecular bone

Georg Fantner

In recent years, the important role of the organic matrix for the mechanical properties of bone has become increasingly apparent. It is therefore of great interest to understand the interactions between the organic and inorganic constituents of bone and le ...

Quantitative study of Portland cement hydration by X-ray diffraction/Rietveld analysis and independent methods

Karen Scrivener, Emmanuel Gallucci

X-ray diffraction (XRD) is a powerful technique for the study of crystalline materials. The technique of Rietveld refinement now enables the amounts of different phases in anhydrous cementitious materials to be determined to a good degree of precision. Thi ...

Laser microspot welding of copper

René Salathé, Thomas Sidler, Simone Amorosi

A new procedure for laser spot welding of thin copper stripes was developed based on measuring the calibrated reflectivity coaxially to the laser beam and using this signal for in situ control of the laser power. Experiments with a power ramp of r=3.1 MW/s ...

29Si and 27Al NMR study of alkali-activated slag

Karen Scrivener, Dehao Wang

This paper presents the results of the investigation of the hydration of alkali-activated slag (AAS) by nuclear magnetic resonance spectroscopy (NMR). The cross-polarization (CP) technique was used in combination with magic-angle spinning (MAS). This resea ...
