Industry separates crude oil, natural gas and chemical mixtures into pure products by means of fractionating distillation columns. This process is energy-intensive, but a new type of column structure ...

The very first life on earth is thought to have developed from 'protocells' -- liquid mixtures of many different types of molecules. Researchers have now shown that in such mixtures, small imbalances ...

Students learn to identify various methods for separating mixtures to define density. Matter: Separation of Mixtures: Students learn to identify various methods for separating mixtures, to define ...

Purification of ethylene (C₂H₄), the largest-volume product of the chemical industry, currently involves energy-intensive processes such as chemisorption (CO₂ removal), catalytic hydrogenation (C₂H₂ ...

A new technology based on the adiabatic cooling of swirling gas flow in a supersonic nozzle is effective in separating and processing natural gas components. A pilot test facility in Alberta, Canada, ...

Liquid chromatography - mass spectrometry (LC-MS) combines two approaches to separate and identify molecules or compounds present in a sample. High performance liquid chromatography (HPLC) separates ...

As a general rule, disclosure of a drug material comprised of a mixture of components, without more, does not render obvious a specific component of that mixture. See, e.g., In re May, 574 F.2d 1082, ...
