Alteration and release of aliphatic compounds by the polychaete Nereis virens (Sars) experimentally fed with hydrocarbons [PDF]

, 2001
In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. After ingestion by the worms, 34.9% of hydrocarbons are found in the faeces and only 3.1% accumulated in the gut.

Defect Chemistry and Chemical Looping Performance of La_1−xM_xMnO₃ (M = Sr, Ca, (x = 0–0.5)) Perovskites

Nanomaterials, 2022
La1−xMxMnO3 (M = Sr, Ca, (x = 0–0.5)) materials of the perovskite structure are synthesized by a co-precipitation method. They are subsequently investigated for their performance in a chemical looping process (fuel CH4) using thermogravimetric analysis ...

Specialized odorant receptors in social insects that detect cuticular hydrocarbon cues and candidate pheromones. [PDF]

, 2017
Eusocial insects use cuticular hydrocarbons as components of pheromones that mediate social behaviours, such as caste and nestmate recognition, and regulation of reproduction.
