Performance of Polymer Solutions for Enhanced Oil Recovery

| Sponsored by Malvern Panalytical

In this article we take an introductory look at work carried out by TU Clausthal to develop an improved understanding of the mechanisms of enhanced oil recovery (EOR) by polymer flooding, and the relevance of fluid rheology. Example data illustrates the insight that rheology provides and its application in optimizing fluid performance.

Combined DLS/Raman provides New Molecular Insights of Complex Fluids

| Sponsored by Malvern Panalytical

In particular, this article demonstrates the correlation between molecular changes (Raman Spectroscopy) and microstructural evolution of rheological properties (DLS, DLS-optical microrheology) for the first time for surfactant-based wormlike micellar system. Whereby, Raman Spectroscopy provides information about the molecular structure and DLS-microrheology characterizes viscoelastic properties, the combination of data delivered allows for a deeper understanding of the molecular changes underlying the viscoelastic ones. The study illustrates the utility of the combined DLS, DLS-optical microrheology and Raman Spectroscopy in providing new molecular structural insights into the self-assembly process in complex fluids.

The optimization and scale-up of high shear granulation

| Sponsored by Malvern Panalytical

This article explains how an inline probe was used to monitor a granulation at three different scales to confirm that, in each case, the granules produced were the same size, and more importantly produced tablets of identical quality as quantified by hardness.

Dairy and Food Emulsions measurement

| Sponsored by Malvern Panalytical

The particle size of the fat droplets present in dairy and other food emulsions is important in defining properties such as flavor release, mouth feel and emulsion stability. Thus, a knowledge of the particle size is critical in defining the functionality and taste of different food emulsion products. Here we show how laser diffraction can be used to measure and understand the changes in size that occur during production and storage of dairy products. This in turn can lead to a better understanding of how product formulation and performance are linked.

Assessing Nanoparticle Toxicity in Waste Water

| Sponsored by Malvern Panalytical

Nanoparticle Tracking Analysis (NTA) has found use in a variety of investigations researching the toxicity and environmental impact of nanoparticles. Here we discuss various publications in which NTA has been used to measure particle size and concentration of nanomaterials in waste water.

Characterizing method for polymers

| Sponsored by Malvern Panalytical

This whitepaper reviews the methods available for measuring the key characteristics of polymers focusing on the benefits and value of gel permeation / size exclusion chromatography (GPC/SEC). Much of the paper talks exclusively about polymers, however many of the principles discussed are equally applicable to proteins or protein conjugate materials.
