The phrase "active system for" is correct and usable in written English.
It can be used when describing a system that is currently functioning or in operation for a specific purpose or task.
Example: "The company has implemented an active system for monitoring employee performance to enhance productivity."
Alternatives: "operational system for" or "functioning system for".
While Co, Ni and Pd complexes displayed low activity, an Fe complex led to an extremely active system for acetylene polymerisation after activation with methylaluminoxane (MAO).
This paper discusses the development of a multichannel active system for local spectral reshaping of multitone noise.
Tuber fruitbodies ('truffles') lack an active system for the dispersal of spores, which are disseminated by the action of mycophagous animals (Pegler et al. [1993]).
A mixture containing 0.4 M AlCl3 and 55 wt% FA was the most selective and active system for the production of furfural at low temperatures (130 °C, selectivity ≈70 90%).
On the basis of this evidence, a catalytic cycle explaining how bimetallic complex 1 and tetrabutylammonium bromide combine to form a uniquely active system for cyclic carbonate can be proposed (Scheme 3).
It has been proposed that high rates of ethylene biosynthesis in climacteric fruit are supported by recycling of the ethylene precursor methionine via the Yang cycle [ 64] and by having an active system for handling cyanide, a byproduct of ethylene biosynthesis [ 65].
In principle, semi-active isolation systems can deliver the versatility, adaptability and higher performance of fully active systems for a fraction of the power consumption.
This property, to a large extent, makes effective the diagnosis of real active systems, for which the reconstruction of the global behavior is often unnecessary, if not impossible.
The strategy of in-situ structure reconstitution by electrochemical reaction described here offers a reliable and valid way to construct the highly active systems for various electrocatalytic applications.
In situ combinations of selected complexes 1a c, 3d and 4e with B(C6F5 3 (1 or 2 equivalents) give active systems for ROP, with high productivity (3.3 5.9 106 gpolym. molZn−1 h−1) and high molecular weight (Mn up to 132 103 g mol−1) for CHO polymerization.
Its accumulation profile is quite similar to that of the annexin, which suggests fruit has active systems for coping with stress that run parallel to the action of CAT (N228 and N229).
