The phrase "active or inert" is correct and usable in written English.
It can be used in contexts discussing substances, materials, or elements that can either be reactive (active) or non-reactive (inert).
Example: "In this experiment, we will analyze the properties of the catalyst, determining whether it is active or inert."
Alternatives: "reactive or non-reactive" or "functional or dormant".
Different coordination environments modulate the chemical characteristics of the zinc ion, control the kinetics of its binding, and allow it to be either metabolically active or inert.
Each of five MPTP-lesioned parkinsonian cynomolgus monkeys received five devices containing active or inert cells grafted bilaterally in the striatum in a two-stage procedure 9 months apart and animals were sacrificed 4 months later for analyses.
Experimental observations suggest that the so-called active or inert oxide residues in the as-made NPG catalysts have almost no effect on the intrinsic catalytic activity of gold, whereas metallic gold plays the catalytic role in this unsupported NPG system.
Chemicals regulated as part of the U.S. EPA pesticide program are generally classified as "active" or "inert".
We hypothesize that such an approach reflects the peak 'window of contact' between cigarette smoke and pulmonary neutrophils, that is, before the instable, reactive intermediates in smoke are diffused and/or metabolized to less active or inert molecules.
Undissociated uric acid, rather than the sodium urate of gouty arthritis, has been recognized as a damage-associated signal, 51 52 and there has been debate about whether uric acid is an active or inert participant in tissue injury.
These radioactive substances, namely radiopharmaceuticals, represent the combination of an unstable radionuclide with an active or pharmacologically inert molecule.
5 Although some distinguish between pure and impure (or inert and active) placebos, it is the lack of specific efficacy that is based on the inherent properties of a compound that makes an intervention a placebo.
By statute or regulation in the United States and elsewhere, pesticide ingredients are divided into two categories: active and inert (sometimes referred to as other ingredients, adjuvants, or coformulants).
The more you learn about the vast expanses of built retail infrastructure — active and inert — the more you wonder whether, perhaps, enough is enough.
Includes, but not limited to, high and medium production volume industrial chemicals, pesticides (active and inert ingredients), and potential ground and drinking water contaminants.
