The influence of hyperbranched polymer grafted polypropylene (PP-HBP) on the morphology of polypropylene (PP)/polyamide 6 (PA6) blends has been investigated. The final morphology was strongly influenced by the PP-HBP compatibilizer concentration. At low co ...
BACKGROUND: We present the synthesis, characterization and initial structure-function analysis of a new class of bioactive agent that allows the application of techniques from colloid science to biological surfaces. Stable colloidal suspensions can be gene ...
A novel optical technique is used to investigate the dynamics of coagulation of particle suspensions with aluminum salt. The relative size of aggregates formed during coagulation, expressed as a ''coagulation index,'' can be continuously measured by this t ...
Novel method for intermolecular cyclization by formation of a biaryl ether bridge through the reaction as shown above. In formulas (I) and (II) R1 is a nitro radical adjacent to the oxygen bridge, Hal is a fluoride or chlorine atom, R2, R3 and R4 together ...
The transition from a liquid to a glass in colloidal suspensions of particles interacting through a hard core plus an attractive square-well potential is studied within the rnode-coupling-theory framework. When the width of the attractive potential is much ...
We discuss the situation where attractive and repulsive portions of the interparticle potential both contribute significantly to glass formation. We introduce the square-well potential as prototypical model for this situation, and reject the Baxter model a ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, comprises the steps of: prepg. a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent , depositing the particle suspension on a ...
The solids are removed from an aq. suspension contg. 4-12 g coal fines/L using a suspension of a water-sol., high-mol. wt., highly crosslinked copolymer of di-Me diallyl ammonium chloride and 0.1-3 mol.% of a crosslinked comonomer, optionally mixed with an ...

The solids are removed from an aq. suspension contg. 0.01-200 g solids/L using a suspension of a water-sol., high-mol. wt., highly crosslinked copolymer of di-Me diallyl ammonium chloride and 0.1-3 mol.% of a crosslinked comonomer, mixed with acryloguanami ...

Hyper Rayleigh scattering in solution is used for the determination of the first order hyperpolarizability b(colloid) of gold colloids in the size range 5–22 nm; these hyperpolarizabilities are found to range from 0.60 × 10–25 esu for 5 nm diameter colloid ...
