Last time, we looked at the practice of 'measuring' in analytical chemistry. We explained how chemists determine the amount of a substance and evaluate the reliability of those numerical values ...

Separating mixtures into their constituent substances is essential in many fields. For example, mixture separation plays a key role in the petrochemical industry, as well as in chemical purification ...

Isolating and purifying rare-earth elements (REEs) is extremely challenging and energy-intensive due to the difficulty in separating chemically similar REE ions. Traditional separation methods require ...

The very first life on Earth is thought to have developed from "protocells"—liquid mixtures of many different types of molecules. Researchers from the University of Göttingen have now shown that in ...

The preceding chapters gave an overview of the many advances in chemical separations and other fields that have emerged in the last 3 decades. Despite the advances, critical challenges remain for the ...

The process of separating useful molecules from mixtures of other substances accounts for 15% of the nation's energy, emits 100 million tons of carbon dioxide and costs $4 billion annually. In a new ...

Industrialized societies rely heavily on advanced materials such as optical fibers, lightweight composites, and silicon microchips for use in a wide range of applications – however, a crucial aspect ...

Image: Core of the new NIST miniature GEMBE chemical separation device (above left) is a machined acrylic block, shown with a quarter for scale. Researchers at the National Institute of Standards and ...

Several industries require essential processes for separating mixtures into their constituent substances. Advancing research, scientists from Japan have now developed a novel, versatile, and ...
