Microbial fuel cell

Willert-Porada M., Lorenz K., Freitag R., Jerome V., Peiffer S., University of Bayreuth, DE

Polymer electrolyte fuel cells, PE-FC, use hydrogen or methanol as fuel. Water soluble organic compounds, like starch, glucose, acetates, can not serve as fuel because of limited catalytic activity of common metal catalysts. Opposite to [...]

Development of a Mobile Asbestos Decontamination Process

Gerdes T., Rosin A., Willert-Porada M., University of Bayreuth, DE

Within the European project “New Safe and Cost Effective Techniques Against Asbestos Risks” different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination [...]

Development of Functionally Graded SiC-Based

Gerdes T., Willert-Porada M., University of Bayreuth, DE

Hot gas filtration using ceramic filters for diesel engine exhaust gas cleaning has gained considerable attention and growth over the last 15 years. In this contribution the development of a SiC-carbide based filter that combines [...]

Nano-Catalysts and Colloidal Suspensions of Carbo-Iron for Environmental Application

Mackenzie K., Hildebrand H., Kopinke F.-D., Helmholtz Centre for Environmental Research - UFZ, DE

The presentation contains two innovative applications of nano-sized materials for environmental application: 1) Pd catalysts for wastewater treatment. The new ferromagnetic nano-sized Pd catalysts have proved effective for selective dechlorination of industrial wastewater. Extraction by [...]

Nanoscale hydrophobic coatings for the separation of liquid mixtures

Truman P., Frenzel R., Longari N., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Organofunctional nanoscale silane coatings are widely used to modify surface chemistry. Such coatings have many applications in micro- and nanofluidics because liquid motion on these scales is strongly influenced by capillary or wall effects. In [...]

Fabrication of Nanoparticulate Inks for Applications in Printable Electronics

Reindl A., Aldabergenova S., Altin E., Frank G., Peukert W., Friedrich-Alexander University, DE

The main impetus of this work is the fabrication of stable suspensions (in regard to aggregation) suitable for a printing process. Therefore semiconducting nanoparticles were dispersed systematically in organic solvents using a variety of methods [...]

Experimental and numerical investigations of the influence of fluid dynamics on the precipitation of nanoscaled particles

Gradl J., Peukert W., Friedrich-Alexander-University of Erlangen-Nuremberg, DE

Precipitation depends on competing kinetics of various interacting parallel and subsequent steps. These are mixing, chemical reactions, nucleation, growth, aggregation and stabilization. The coupling of all subprocesses is the key for predicting the PSD. In [...]

Photochemical Alteration of the Stability of Polymer Nano-Agglomerates

Seipenbusch M., Rothenbacher S., Weber A.P., Salas-Vicente J., Braun A.M., Kasper G., University of Karlsruhe, DE

Interparticle adhesion in the nano-regime leads to undesired stable agglomerates in particulate products. On one hand, the high surface energies of nanoparticles favor the reduction of overall surface area by maximization of the number of [...]
