You can use it when discussing the origin or source of a substance in a scientific or technical context.
Example: "The researchers isolated a substance from a rare plant species that showed potential medicinal properties."
Alternatives: "a material derived from a" or "a compound extracted from a".
Dr. Levine remembers trying to clean a substance from a beaker when he was a biology major at Brandeis University.
The transport model of a substance from a diffusive source can be obtained by solving the corresponding diffusion equation.
Diffusion is a process of net movement of a substance from a high-concentration region to a low-concentration region.
We assume that the sensor nodes are in sleep mode until they are activated by some central control (i.e., FC) due to a possible release of a substance from a diffusive source.
Clearance represents the removal of a substance from a unit of volume over a unit of time, typically expressed in milliliters per minute.
G15, a substance from a compound library, was reported to be selective for GPR30 and inhibited signal transduction of GPR30 [ 14].
This is another method used to prevent a substance from interfering with an assay.
Faraday, who was Davy's assistant at the time, studied electrolysis quantitatively and showed that the amount of energy needed to separate a gram of a substance from its compound is closely related to the atomic weight of the substance.
But he cautioned that such a scenario would have required a "massive release" of a substance from the wreck of the Mira – unlikely after almost 100 years at the bottom on the sea.
As an effort to minimize the thermal shrinkage of PE separators, in this study, we coat PE separators with a substance from the polyimide family by engaging a simple dipping method.
He showed that heating a metal to form a powder requires a substance from the air.
