New catalysts and receptors by self-assembly and combinatorial chemistry

New methods that allow the generation of transition metal-based catalysts and receptors are discussed. It is shown that heterobimetallic, halogeno-bridged complexes are well-suited for screening assays in combinatorial catalysis. Metal catalysts with a str ...

Nanoscale dispensing of liquids through cantilevered probes

Nico de Rooij, Terunobu Akiyama, Sylvia Jeney, André Meister

Nanoscale dispensing is a novel technique to deposit material and create structures at dimensions of 100 nm and below. It has great flexibility in feature shape and choice of deposited material. Due to its potential low cost and lack of time consuming step ...

Heterogeneous reactions of tropospheric trace-gases on solid model aerosol surface

Christian Santschi

The first part of this laboratory study deals with heterogeneous reactions of bromine- and chlorine-containing species relevant to the atmosphere with solid model alkali salt substrates. The second part of this work treats the heterogeneous interaction of ...

Generally applicable fed-batch culture concept based on the detection of metabolic state by on-line balancing

Urs von Stockar, Ian William Marison, Christoph Herwig, Bernhard Walker

In many microorganisms, flux limitations in oxidative metab. lead to the formation of overflow metabolites even under fully aerobic conditions. This can be avoided if the specific growth rate is controlled at a low enough value. This is usually accomplishe ...

Dimensionally Stable Anode-Type Anode Based on Conductive p-Silicon Substrate

Christos Comninellis, György Foti, Lassine Ouattara, Ilaria Duo, Marco Panizza

In the search for a good dimensionally stable anode-type electrode, p-silicon (1-3 mW cm) has been chosen as the substrate material due to its high anodic stability and its reasonable cost compared to titanium and tantalum. Several p-Si/IrO2 electrodes hav ...

High-strength ceramic substrates for thick-film sensor applications

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol

Force and pressure sensors based on the piezoresistive properties of thick- film resistors have recently found wide application due to their low cost, reliability, and relatively good precision. Achieving high elastic mechanical strains is important to max ...

Calmodulin-tagged phage and two-filter sandwich assays for the identification of enzymatic activities

Christian Heinis, Dario Neri

The procedures for calmodulin-tagged phage and two-filter sandwich assays for the isolation of enzymic activities are presented. In the first method, enzymes are displayed on filamentous phage, and the reaction substrate is anchored on the calmodulin-tagge ...

Dependence of the O-2 diffusion rate on oxide thickness during silicon oxidation

Alfredo Pasquarello, Angelo Bongiorno

We address the rate of O-2 diffusion through the oxide layer at Si-SiO2 interfaces using an atomic-scale approach. In particular, we investigate the combined effect of a percolative diffusion mechanism and of a dense oxide layer located close to the silico ...

Influence of oxygen flow on crystallization and morphology of LiNbO3 thin films

Nava Setter

Polymeric precursor solution (Pechini method) was used to deposit LiNbO3 thin films by spin-coating on (100) silicon substrates. X-ray diffraction data of thin films showed that the increase of oxygen flow promotes a preferred orientation of (001) LiNbO3 p ...

Examining reactivity and specificity of cytochrome c peroxidase by using combinatorial mutagenesis

Kai Johnsson, Claudio Arrivoli, Petra Tafelmeyer, Martin Wilming

Combinatorial mutagenesis was used to investigate the role of three key residues in cytochrome c peroxidase (CCP) from Saccharomyces cerevisiae, Arg48, Trp51, and Trp191, in control of the reactivity and selectivity of the heme-contg. enzyme. Libraries wer ...
