What do recent winners of the Nobel Prize tell us about the future of science?

The sophisticated chemistry behind a simple – yet infectiously popular – purple dye

Using “chemical record” from jellyfish to create a stable isotope-based map of the seas

Is your viscometer approaching the end of its life? Are you starting to feel that your trial and error, ‘rheology-light’ approach to formulation is becoming dated? Or are there longstanding product performance issues that you’re failing to gain traction with, where you suspect rheology may hold the answer?

This application note describes a selection of measurements made on a GE AKTA basic system.

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.

Quantifying Nanoparticle Concentration and Size to Optimize Filtration Processes

The core of Uranus could contain significant amounts of exotic chemical compounds

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.

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.
