Oxidation of Metallic Nanoparticles

A. Auge[1], A. Weddemann[1], F. Wittbracht[1], B. Vogel[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

The oxidation behavior of metallic nanoparticles is investigated in respect to material parameters like Mott potential, defects on the microstructure and oxide volume increase per ionic defect. An emphasis is laid on magnetic nanoparticles where the degree of oxidation can be measured ... Read More

Flow Simulation In A Submerged Membrane Bioreactor At Laboratory Scale

Y.M. Carreño-Martinez, J.M. Gozalvez-Zafrilla, J.A. Mendoza-Roca, and A. Santafé-Moros
Universidad Politecnica de Valencia, Spain

Submerged membrane bioreactor (SMBR) is an efficient technology for wastewater treatment that combines biological process and membrane filtration in one single stage. In the most usual configuration, submerged membrane hollow fibers are set in several planes. Air is introduced from the ... Read More

Simulation of Flaw Signals in a Magnetic Flux Leakage Inspection Procedure

O. Nemitz, and T. Schmitte
Salzgitter Mannesmann Forschung GmbH, Duisburg, Germany

In the inspection of steel products with respect to flaws a magnetic flux leakage (MFL) test procedure can be applied. In this procedure a “horseshoe” shaped yoke is used, whose legs are wrapped with coils through which an alternate current with a high frequency (3 kHz) is flowing. ... Read More

Microfluidic Design of Neuron-MOSFET based on ISFET

A. Jain[1], and A. Garg[2]
[1]BITS Pilani, Goa, India
[2]Bhartiya Vidyapeeth College, New Delhi, India

In this paper we suggest a device which combines the operation of a neuron-MOS and an ISFET. An ISFET is an ion-sensitive field effect transistor used to measure ion concentrations in a solution; when the ion concentration changes, the current through the transistor changes accordingly. ...
