Stevenson et al. (2015) studied the possible formation of a new type of membrane made up of small N-organics capable of forming vesicles in liquid methane at low temperatures, called azotosomes.
“These authors studied the possible formation of a new type of membrane, made up of small N-organics, capable of forming vesicles in liquid methane at low temperatures.They call these 3D structures “azotosomes” as an analogue of liposome.”
From The Emergence of Life (2019) · cites this paper as Stevenson et al. (2015)
Using molecular modeling, Stevenson et al. found that the best azotosome results are obtained with acrylonitrile, forming vesicles with a diameter of 90 Å.
“Their theoretical study shows that the best results are obtained with acrylonitrile (vinyl cyanide), where azotosome vesicles with a diameter of 90 Å are formed.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
