Polyimide and SU-8 microfluidic devices manufactured by heat- depolymerizable sacrificial material technique

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet, Stefan Metz

The following paper describes a sacrificial layer method for the manufacturing of microfluidic devices in polyimide and SU-8. The technique uses heat-depolymerizable polycarbonates embedded in polyimide or SU-8 for the generation of microchannels and seale ...

Preserving tropical soil organic matter at watershed level. A possible contribution of urban organic wastes

Claudia Rebeca Binder Signer

The goal of this paper is to put the issue of preserving Soil Organic Matter (SOM) into a regional, urban-rural, context. In doing so, we apply the method of material flux analysis to a watershed in Boyacá in Colombia. We estimate the order of magnitude of ...

Effects of elevated CO2 and mineral nitrogen deposition on growth, allocation and decomposition of Sphagnum fallax, Polytrichum strictum and Eriophorum vaginatum in a Sphagnum bog.

Andy Siegenthaler

Atmospheric CO2-C sequestration is directly related to the formation of peat which in turn is dependent on the production and decomposition of plant material. We studied the various aspects of qualitative and quantitative growth, litter production and deco ...

KNb4O5F and NbO2 crystal structures. Structural aspect of chemical decomposition of K2-xNb4O3(O,F)(3)F in the melt of sodium and potassium chlorides

Gervais Chapuis, Alla Arakcheeva

The structures of the KNb4O5F (I) (synthesized for the first time) and the NbO2 (II) phases formed together with NbO during decomposition of reduced oxofluoroniobate K2-xNb4O3(O,F)(3)F (III) in the (NaCl + KCl) melt are studied by X-ray methods. The tetrag ...

On the Decomposition of Polychotomies into Dichotomies

Many important classification problems are emphpolychotomies, emphi.e. the data are organized into KK classes with K>2K>2. Given an unknown function F:Omegato1,dots,KF : Omega to {1, dots, K} representing a polychotomy, an algorithm aimed at ``learning'' this polychotomy ...

On the Decomposition of Polychotomies into Dichotomies

Many important classification problems are \emph{polychotomies}, \emph{i.e.} the data are organized into KK classes with K>2K>2. Given an unknown function F:Ømega{1,,K}F : Ømega \to \{1, \dots, K\} representing a polychotomy, an algorithm aimed at ``learning'' this p ...

Organometallics on Silicon - a Synchrotron-Radiation Photoemission-Study of the Adsorption of Iron Pentacarbonyl on Si(111) Surfaces with Different Reconstructions

Giorgio Margaritondo

The adsorption behaviour of Si(111)2 x 1 and Si(111)7 x 7 surfaces towards Fe(CO)5 has been investigated in the temperature range 80-300 K and in the exposure range 0.1-1000 L. For both surface reconstructions, the adsorption state is found to be molecular ...
