Prof. Cernicharo (NANOCOSMOS PI) has been awarded the 2018 Gold Medal of the Spanish Royal Physical Society and BBVA Foundation for his outstanding merits, impact and leadership in Molecular Astrophysics at the international level. Congrats!
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).
This research was presented in the paper “Precisely controlled fabrication, manipulation and in-situ analysis of Cu based nanoparticles“, published in Scientific Reports 8, 7250 (13pp), 2018 May 8.

Within the framework of the ERC-Synergy “Nanocosmos” project, we are seeking a senior post-doctoral researcher to work on: “Laboratory astrophysics simulation experiments using the Stardust machine”.
The candidate should have a strong expertise in some of the following fields: Laboratory Astrophysics, Surface Science (fundamentals and techniques), Ultra-High Vacuum systems (use and engineering), nanoparticle growth and solid-phase Physical-Chemistry. A good record of publications in peer-reviewed journals is a strong asset. The successful candidate will participate in on-going operations of the Stardust machine, being an interface between astrophysicists and surface scientists. The applicant must have an excellent knowledge in English, both written and spoken. The position will be filled for a fixed term of 2 years with a possible renewal until the end of the project in July 2020. The starting date of the position will be as soon as possible.
Applications. If you are interested in this position, please submit your CV together with a motivation letter and a recommendation letter, ALL IN ONE SINGLE PDF FILE, at the latest by the 15th of October, to: Prof. J. A. Martín-Gago (gago at icmm.csic.es)
The “Stardust” machine is an innovative experimental station devoted to the production, processing and in-situ analysis of any type of cluster or nanoparticle made up to three different materials by means of a scaled-up multiple ion cluster source, in a highly controlled ultra-high vacuum environment. Stardust has been designed to simulate the complex conditions of cosmic-dust formation and processing in the circumstellar region of evolved stars and supernova.

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.
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.

The paper “Compression and ablation of the photo-irradiated molecular cloud the Orion Bar” (Goicoechea et al. 2016) recently published in Nature, has put Astrochemistry and NANOCOSMOS in the leading edge forefront of many research institutIons, newspapers and mass media. A few examples can be found below:
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.
Christine Joblin, one of the NANOCOSMOS project PIs, has been awarded chevalier of the National Order of the Legion of Honour for her public service and professional activities with eminent merits in scientific research both at the national and international levels. Christine Joblin is a research director at the Centre National de la Recherche Scientifique (CNRS) in l’Institut de Recherche en Astrophysique et Planétologie (IRAP, Université Toulouse 3).
