Food materials, due to their physical and chemical complexity, have had limited success with microfluidic processes.
One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past.
"If we can understand the chemical complexity of these ices in the molecular cloud, and how they evolve during the formation of a star and its planets, then we can assess whether the building blocks of life should exist in every star system," Melissa McClure of the Universiteit van Amsterdam, the principal investigator on a NASA research project to investigate cosmic ices, said in ( a statement Friday.
Introduction/Background: The quality assurance of herbal products is particularly challenging due to their chemical complexity and natural variation.
The chemical complexity is further magnified since many of these CECs are not environmentally stable and break down into other forms," Letcher says.
For healthcare designers, Fiser says the protocols could be used to help determine the impact of furniture specification or understand the chemical complexity of a product and its impact on health.
The extracts that occupy this space defy simple categorization because they represent a continuum based on their chemical complexity. A broad or wide-spectrum extract contains a large array of extracted constituents, while narrow-spectrum extracts have a much simpler chemical makeup.
The concluding chapter describes the challenges in defining gene-nutrient interactions because of chemical complexity of food, genetic heterogeneity of humans and complexity of physiological responses to nutrient intake in health and disease.
The standard scientific view assumes life to have originated not in a single leap from simple chemicals to cells but through gradual accumulations of chemical complexity. Yet the junkyard tornado analogy spins on, often shorn of its origin-of-life context and serving as a supposed point against any evolutionary change.
However, the chemical complexity of the water-based paints, which include substances with known irritative and allergic properties, led to cases of skin irritation, eye irritation and stomach problems.
