July 2016 Issue of The Analytical Scientist

Welcome to the July issue! In Upfront, we trace the lead in lipstick and meteoritic material in Tutankhamun’s dagger, plus we meet the team analyzing the changing climate’s effect on maple syrup. In My View takes on the dark side of scientific publishing, while in Profession, young scientists are urged to take a leap of faith in their careers. Giuseppe Petrucci shares his fascinating journey through the world of atmospheric chemistry – and from the vast to the very small, Donald Chace discusses the role of forensics in newborn screening.

Ten Ways to... Control Rheology by Changing Particle Properties

The newest addition to the popular ‘10 ways to…’ series of educational papers provides practical guidance on developing high performance suspension products with enhanced consumer appeal. ‘10 ways to...control rheology by changing particle properties’ explores how controlling particle characteristics, such as particle size distribution, concentration and zeta potential, enables formulators to engineer suspension performance. Suspensions are used in the formulation of a wide range of every day products from medicines, drinks and foodstuffs to paints, inks and coatings. This paper is therefore valuable to formulators working across a wide range of industries.

Sizing up the Solution

This article explores the role of different components within drilling muds, including barite and calcium carbonate. The need to achieve optimum particle sizes is examined, the application of laser diffraction is considered within this context. Fast, efficient and having a wide measurement range, laser diffraction delivers accurate, precise and reproducible particle size information. Offering automated analysis, it is a preferred method for drilling mud particle sizing and the focus of ongoing API efforts to develop a standard in this area.
