• Making the connection - particle size, size distribution and rheology
  

  A number of factors influence the rheology of a suspension, including particle size, particle size distribution, and the volume fraction of solids present. Here we examine the relationship between rheology and particle size parameters. Commonly used rheological terms are described and we present data from example systems to illustrate key points more

• Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization
  

  High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more

• Do you see the complete picture?
  

  Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more

• Density and Viscosity for Binary Mixtures of Diethylene Glycol Monobutyl Ether with Monoethanolamine, Diethanolamine, and Triethanolamine from (293.15 to 333.15) K

  Density and viscosity for binary mixtures of diethylene glycol monobutyl ether (DEGMBE) with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) have been measured as a function of composition from (293.15 to 333.15) K at intervals of 10 K under ambient pressure. Densities were m more

• Ultrasound Viscosity Measurements Allow Determination of Gas Volume Fraction in Foamed Gels

  Abstract Aerated whey protein gels were obtained by gelation of preheated solutions at room temperature by calcium, magnesium and ferrum (II) ions at different pH and protein concentration. The density of aerated and non‐aerated gels was determined by the flotation method. Dynamic viscosity of more

• Synthesis and characterization of starch‐graft‐polyacrylamide copolymers and their application as filtration control agents in drilling fluid

  Abstract Some starch‐graft‐polyacrylamide copolymers were prepared by the polymerization of corn starch with acrylamide in aqueous medium using a complex initiation system consisting of ceric ammonium sulphate and ammonium persulphate. The copolymers were applied to water‐based drilling fluid as more
