Hamaker 2: A Toolkit for the Calculation of Particle Interactions and Suspension Stability and its Application to Mullite Synthesis by Colloidal Methods

Paul Bowen, Ulrich Aschauer

For modern processing of ceramics at the nanoscale, the influence of interparticle interactions in the suspended state becomes increasingly important. The Hamaker 2 program has been developed for the rapid prediction of these interactions, allowing us to g ...

Nitrogen removal from digested manure in a simple one-stage process

Christof Holliger

A process based on partial nitrification and recirculation into the anaerobic digester was studied to remove nitrogen from digested manure and thus reduce enhanced gaseous ammonia emissions due to on-farm biogas production. An anaerobic reactor representin ...

Morphology of polymer/clay latex particles synthesized by miniemulsion polymerization: Modeling and experimental results

John Christopher Plummer

BA/MMA (90:10 wt.-%) were copolymerized in the presence of two different organomodified clays (C30B and CMA16) and 1.6-2.6wbm.-% surfactants. The effect of the compatibility of the organoclay in the monomer mixture on the morphology of hybrid polymer/clay ...

Rheological behavior of concentrated hyperbranched polymer/silica nanocomposite suspensions

Yves Leterrier, Valérie Geiser

The rheological behavior of two hyperbranched polymer/silica suspensions with different dispersion states, surface chemistries, and concentrations of the silica nanoparticles was investigated in terms of viscoelastic properties, activation energy for visco ...

Rheophysics of concentrated particle suspensions in a Couette cell using a refractive index matching technique

Sébastien Wiederseiner

The main objective of this work is to gain insight into the rheometry and rheology of concentrated non-colloidal particle suspensions. Among the many questions that have as yet received little answers, we are especially interested in the rheometric problem ...

Products of abiotic U(VI) reduction by biogenic magnetite and vivianite

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Daniel Scott Alessi

Reductive immobilization of uranium by the stimulation of dissimilatory metal-reducing bacteria (DMRB) has been investigated as a remediation strategy for subsurface U(VI) contamination. In those environments, DMRB may utilize a variety of electron accepto ...

Pattern-Based Sensing of Short Oligodeoxynucleotides with Palladium–Dye Complexes

Kay Severin, Jie Gao, Anton Granzhan

The colorimetric response of a sensor array composed of palladium–dye complexes can be used to identify different hexadeoxynucleotides and to distinguish mixtures of sequence-isomeric hexadeoxynucleotides. ...

Pattern-Based Sensing of Sulfated Glycosaminoglycans with a Dynamic Mixture of Iron Complexes

Kay Severin

A dynamic mixture of iron complexes was used as a colorimetric sensor for sulfated glycosaminoglycans. The sensing ensemble was prepared by mixing [FeCl2(H2O)4] with dipicolylamine, the functionalized bipyridyl ligand N-(6-aminohexyl)-4'-methyl-2,2'-bipyri ...

Cathode-supported micro-tubular SOFCs based on Nd1.95NiO4+delta: Fabrication and characterisation of dip-coated electrolyte layers

Jan Van Herle, Heinrich Hofmann, Paul Bowen, Josef Andreas Schuler, Ulrich Aschauer

Fabrication conditions to obtain dense electrolyte double layers on a porous micro-tubular cathode substrate were investigated. Porous tubes of a nickelate material, Nd1.95NiO4 + delta, were fabricated by cold-isostatic pressing (CIP) and sintering. Thin f ...
