The starting signal to unveil the formation of dust grains in AGB stars

The Stardust machine has been constructed to simulate the formation of dust grains in the atmospheres of Asymptotic Giant Branch Stars (AGBs), their evolution and further interaction with the ambient UV radiation.

On May 8, 2018, the first paper on the NANOCOSMOS Stardust machine has been published at the “Scientific Reports” journal (Scientific Reports, volume 8, Article number: 7250 (2018)).
After almost 4 years of hard work at the Instituto de Ciencia de Materiales de Madrid (ICMM-CSIC), the article comprises the stages of the design, development, commissioning and first-light experiments of this innovative experimental station.

Stardust integrates a precise tool to fabricate high quantities of complex nanoparticles, perform in-flight manipulation and in-situ characterization, all through five Ultra-High Vacuum (UHV) modules assembled. The article presents the precise fabrication, manipulation and in-situ analysis of Cu nanoparticles, as part of the commissioning of the machine.

To the best of our knowledge, several milestones have been achieved, such as:
– The new design of the scaled-up Multiple Ion Cluster Source (MICS) addresses a significant step-forward towards industrial implementation of gas aggregation sources, for applications with special requirements such as controlled purity, size distribution, stoichiometry and structure of the nanoparticles.
– First-time accurate control of the Cu oxidation state through reactive sputtering using gas aggregation sources that avoids poisoning of the target by injecting large amounts of oxygen.
– Integration of several techniques that combine the fine control of nanoparticle fabrication with high throughputs, in-flight manipulation (i.e.: gas injection at different stages, heating, accelerating, …) and in-situ characterization (electron spectroscopy techniques and thermal desorption spectroscopy).

Salary. The salary of the position is determined in accordance with the salary system of CSIC (Spain National Research Council) which amounts between €36.000/€40.000 gross in 14 instalments. In addition, funds for travel and allowance to conferences and workshops are covered up by the project.

ECLA2016 conference ready to go!!

From next Monday 21 till Friday 25, the European Conference on Laboratory Astrophysics (ECLA2016 – Gas on the Rocks) will take place at the CSIC headquarters in Madrid. The opening act will be led by the president of CSIC, Emilio Lora-Tamayo, together with the Director of the Instituto de Ciencia de Materiales de Madrid (ICMM-CSIC). Federico Soria, and José Cernicharo (SOC chair), Christine Joblin (SOC co-chair) and Isabel Tanarro (LOC chair).

More than 170 scientists worldwide (astrophysicists, physicists, chemists and engineers) will address the state of the art in laboratory astrophysics within the context of new exciting astrophysical data. In order to achieve a closer collaboration in the analysis and interpretation of astrophysical and laboratory data, nearly 80 talks and 90 posters will be presented at the conference.

A dedicated press room will be available at the conference webpage. Several scientists will be interviewed to show the general public how science can improve our current understanding on fundamental questions such as the formation of planetary systems and molecular complexity in Space as well as the interrelation between technological developments and top laboratory studies to address these fundamental questions.

Stay tuned!!

Nature paper led by NANOCOSMOS members

The Nature Journal published yesterday a paper entitled “Compression and ablation of the photo-irradiated molecular cloud the Orion Bar”, led and with the participation of several members of our group.

One-arcsecond-resolution millimetre-wave images taken with ALMA enable the ‘skin’ of the Orion molecular cloud to be resolved. The stunning images reveal a fragmented ridge of high-density filamentary substructures, photoablative gas flows and instabilities that suggest that the cloud edge has been compressed by a high-pressure wave expanding into the molecular cloud. These results are in contrast to predictions from static equilibrium models and reveal a very dynamic UV-irradiated cloud edge.
