The phrase "a reduced atmosphere" is correct and usable in written English.
It can be used in scientific contexts, particularly in discussions about planetary atmospheres or chemical reactions where the amount of oxygen or other gases is lower than normal.
Example: "The researchers simulated a reduced atmosphere to study the effects on microbial life."
Alternatives: "an oxygen-poor atmosphere" or "a low-oxygen environment".
By carefully controlling the reaction conditions, nanowires of Fe3O4 are directly acquired from nanowires of α-Fe2O3 in a reduced atmosphere at 410 430 °C.
The crystallization behavior of 40BaO 20TiO2 40SiO2 glass (mol%) in a reduced atmosphere (7%H2/93%Ar) is examined to develop a new approach for the design and control of the morphology of nonlinear optical fresnoite (Ba2TiSi2O8) crystals.
The present paper reports the impulsive excitation of mechanoluminescence (ML) in SrAl2O4 Eu, Dy phosphor prepared by solid state reaction technique in a reduced atmosphere of 95%Ar+5%% H2.
The minimum resistivity of 1.3×10−3 Ω cm was obtained for the film doped with 2 wt.% Al, preheated at 400 °C and post-heated at 600 °C, after annealing under a reduced atmosphere of forming gas.
After pressure reduction, the reaction was continued for 45 h at 120°C under a reduced atmosphere.
Oxygen production by photodissociation gave the early reduced atmosphere a start toward present-day conditions, but it was not until the appearance of photosynthetic organisms approximately 3.3 billion years ago that it was possible for the accumulation of oxygen in the atmosphere to proceed at a rate sufficient to lead to today's oxygenated environment.
The superconducting properties of the (LRE BCO single grains fabricated by this process are, in all respects, equivalent to those processed more conventionally in a reduced oxygen atmosphere.
When the same petri plates were incubated under a reduced O2 atmosphere (2% O2, 5% CO2, bal. N2), strain 66205 colonies appeared light-blue, or partially induced.
0.9 salt were dehydrated in a reduced humidity atmosphere at +5°C to a water content of 0.9 g/g dry weight.
The strongest correlation, of transcripts and heterocyst specific protein levels, was detected in cluster 4, which included genes strongly transcribed after the establishment of a reduced oxygen atmosphere inside the developing heterocysts.
Surface oxidation of the SrMoO3 film is suppressed using a thin cap interlayer of Ba0.6Sr0.4TiO3−δ grown in reduced atmosphere.
