It can be used when discussing substances that are synthetically produced rather than naturally occurring, often in contexts related to food, agriculture, or chemistry.
Example: "Many consumers are concerned about the presence of artificial chemicals in their food products."
Alternatives: "synthetic compounds" or "man-made chemicals".
But these low-carb snacks were just putting these artificial chemicals right back in.
Intensive farming, rapid industrialization, and increasingly sophisticated lifestyles have added artificial chemicals into many water bodies.
Organic generally refers to farming methods without the use of chemical fertilisers, pesticides and other artificial chemicals.
Artificial chemicals known as chlorofluorocarbons, or CFC's, once ubiquitous in aerosol spray cans and air-conditioner coolant, cause a chain of reactions that destroy ozone.
For pregnant women or those concerned about artificial chemicals, many health food stores carry permanent hair color free of ammonia, alcohol and hard chemicals, like Herbatint, an Italian brand.
Synthetic cannabis is artificial chemicals sprayed on to a dried plant material, and despite being illegal in Massachusetts, it's frequently available at gas stations and mom-and-pop stores, usually marked as incense or pot pourri.
LARES is a global stochastic optimization algorithm based on the artificial chemical process paradigm.
However, the study of how molecules can 'think' has not produced an equal variety of computational models and applications of artificial chemical systems.
This switch can turn gene expression up, down, or off in response to an artificial chemical not found in mice or their diets.
Organic farming does not use artificial chemical fertilisers, instead building soil fertility through crop rotations and particularly the use of clover that fixes nitrogen naturally from the atmosphere using the sun's energy.
Although biomolecular systems have been hypothesized to carry out neural-network-like computations in vivo3,2,4 and the synthesis of artificial chemical analogues has been proposed theoretically5,6,7,8,9, experimental work10,11,12,13 has so far fallen short of fully implementing even a single neuron.
