[SummerNews #5 ] For the first time, large-scale #PAHs (polycyclic aromatic hydrocarbons) (> 50 #carbon atoms) have been discovered in a carbonaceous #asteroid sample: #Ryugu 👍 👏

Brought back by the #Hayabusa2 mission from JAXA, this sample was the subject of a unique #surface mass spectrometry technique based on two-stage #laser desorption/ionization, available on the #AROMA device at IRAP.

[#SoutenanceHDR] This Friday morning, Hassan Sabbah, Assistant Professor at Toulouse III University and researcher at @IRAP, will defend his Authorization to Direct Research on the "Origin and Evolution of Cosmic #PAHs ".

These carbonaceous #molecules are omnipresent in #astrophysical environments. They are involved in particular in the physicochemical processes of stellar and planetary formation.

@Snoro
Un système type #PAHS (passive annual heating system) local, il y a encore des ingénieurs sensés :)

Quand les conditions sont réunies (pas ici apparemment), c'est encore plus intéressant de stocker directement l'énergie solaire thermique ou éolien mécanique, ça enlève une phase de conversion et ça enlève grandement les dépendances minières externes (énormes générateurs electriques).
