Current mechanical design of SAMPLE. (a) Isometric view of the complete mechanical assembly, illustrating the spatial configuration of the internal components. (b) Isometric view, emphasizing the key structural elements: the

Illustration of the range of possible internal compositions for temperate sub-Neptunes like K2-18 b, and a roadmap to characterize them through atmospheric observations. A liquid-water ocean separating the atmosphere from

The chemical process begins with the activation of a fatty acid, which then spontaneously couples with a lysophospholipid (LP) to generate a phospholipid. The chemical linkage formed is transient and
