[đŸ‡«đŸ‡· version FR 👇] Another experiment, and another timelapse! This time, I’m working with the Fluid Science Laboratory (FSL), one of the science facilities inside ESA’s Columbus module.

The experiment is called PASTA-3 and investigates the formation and evolution of emulsions over time when there is no gravity to interfere. Emulsions are mixtures of two or more liquids that do not usually mix, such as oil and water.

During this session, I installed 3 experiment containers đŸ§Ș with new samples inside the FSL. Each PASTA sample has a different concentration of surfactant (an agent that helps liquids mix) and Xanthan Gum in addition to a water and oil mixture.

This experiment helps scientists better understand and model the fundamental physics of emulsions. That knowledge has numerous applications on Earth, including:
improving food quality and shelf life (milk đŸ„›, dough, mayonnaise, candy
),
enhancing the stability and effectiveness of medicines (including vaccines 💉) and cosmetics,
optimising processes in industrial and advanced manufacturing sectors (oil đŸ›ąïž, chemicals 
).

PASTA-3 is one of the 36 European experiments I get to work on during my mission! Go science!

(PASTA is short for PArticle STAbilised emulsions experiment.)

Nouvelle expĂ©rience, et nouveau timelapse ! Cette fois-ci, cela se passe dans le Fluid Science Laboratory (FSL), l’une des installations scientifiques situĂ©es Ă  l’intĂ©rieur du module Columbus de l’ESA.

L’expĂ©rience s’appelle PASTA 3 : elle Ă©tudie la formation et l’évolution des Ă©mulsions au fil du temps en l’absence de gravitĂ©. Une Ă©mulsion, c’est un mĂ©lange de deux ou plusieurs liquides qui ne se mĂ©langent pas facilement, comme l’huile et l’eau.

Lors de cette session, j’ai installĂ© trois lots de nouveaux Ă©chantillons đŸ§Ș dans le FSL. Chaque Ă©chantillon PASTA prĂ©sente une concentration diffĂ©rente de tensioactif (un agent qui aide les liquides Ă  se mĂ©langer) et de gomme xanthane, en plus d’un mĂ©lange d’eau et d’huile.

Cette expérience aide les scientifiques à mieux comprendre et modéliser la physique fondamentale des émulsions avec à la clé de nombreuses applications sur Terre, comme par exemple:
l’amĂ©lioration de la qualitĂ© des aliments et de leur durĂ©e de conservation (lait đŸ„›, pĂąte, mayonnaise, confiseries
),
le renforcement de la stabilitĂ© et de l’efficacitĂ© des mĂ©dicaments (y compris les vaccins 💉) et des cosmĂ©tiques,
l’optimisation des procĂ©dĂ©s industriels et de fabrication avancĂ©e (pĂ©trole đŸ›ąïž, chimie
).

PASTA 3 est l’une des 36 expĂ©riences europĂ©ennes sur lesquelles j’ai la chance de travailler durant ma mission ! Vive la science !

(PASTA est l’abrĂ©viation de PArticle STAbilised emulsions experiment.)
