How can a network of citizens and smartphones measure atmospheric particles?

Rheology is the science of material flow. It is also a science with a reputation for some fairly daunting mathematics. But look past these first principles and rheology has immediate relevance in formulation which is readily appreciated and easily exploited.

Whey is a by-product of the cheese-making process, and Whey Protein Isolate (WPI) is a dietary supplement and food ingredient created by separating components from milk. It contains a high percentage of pure protein and can be pure enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free. In this application note, a sample of WPI was characterized using the Viscotek TDAmax. The 4 main components in this mixture were separated and individually characterized.

This application note presents an example of how calorimetry aided the formulation development for ProX by providing insight into excipient-protein interactions. Polysorbate-80 and phenol are examined here as potential additives to the formulation buffer for ProX.

Analytical QbD (AQbD) promises to extend the rigor and benefits of QbD into the area of analytical method development.

A nanowire-based prototype “supersensor” can detect the fingerprint of explosives down to parts per quadrillion

A multitude of wearable biosensors for monitoring our personal health and the external environment are on the way, led by technologies to improve performance in sport and all-round fitness. They are easy to use, will cost little and provide useful, real-time information. Stand by for the democratization of analysis.

QEPAS offers highly sensitive portable sensing of nitrous oxide and methane – two of the nastier greenhouse gases

The development of Orbitrap™ has taken up all of my professional life. It’s been a story of luck, perseverance, and, ultimately, success.

Is “accelerator-on-a-chip” technology the tipping point for cheaper, smaller devices for science and medicine?
