The dispersion of nanosized gamma aluminas with high specific surfaces areas (100 m2 /g) and primary particle sizes around 20 nm, using polyacrylic acid, has been investigated. The effect of pH and polymer concentration showed that the highest density gree ...
In automotive engineering, the main load bearing structure (Body-in-White, BIW) has traditionally been manufactured using metals such as steel and light alloys. In order to satisfy upcoming European regulations on CO2 emissions, considerable weight reducti ...
Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substra ...
Experiments on vortex shedding from a cylinder placed in uniform flows of low concentration polymer solutions are reported for Reynolds numbers from 50 to 150. The fluids used were aqueous solutions of polyethylene oxide (PEO) and rheological characterizat ...

The Buss-Kneader is generally known as a compounding device. Although a reasonable number of papers have been published on extruders as polymerization reactors, only little is known about the behavior of the Buss-Kneader when used as a polymerization react ...
The present PhD thesis deals with the high temperature polymerization of methyl methacrylate in a continuous pilot scale process. The major aim is to investigate the feasibility of a polymerization process for the production of PMMA molding compound at tem ...
A new class of water-soluble, amphiphilic star block copolymers with a large number of arms was prepared by sequential atom transfer radical polymerization (ATRP) of n-butyl methacrylate (BMA) and poly-(ethylene glycol) methyl ether methacrylate (PEGMA). A ...
Two dimensionally ordered, monodisperse nanoparticle arrays of metals, metal oxides and possibly alloys can be obtained by using functional diblock copolymer micelles as templates. Tunability of the block copolymer micelle sizes and periodicities has been ...
Stimuli-responsive polymers have the unique property of undergoing a reversible phase transition. This property has attracted much interest for their application in the field of medicine and biotechnology, such as drug delivery systems. Linear polymers of ...
