New Nanocosmos Doctor

Some news from the young team surrounding our PI from Toulouse, Christine Joblin. Sarah Rodríguez Castillo (third on the left, first row) presented on October 30th 2018 her PhD thesis entitled “Study on the dissociation of astro-PAHs”, that was carried out at the University of Toulouse/CNRS in the framework of the Nanocosmos projet.

Congratulations on this great achievement, Doctor!


Polycyclic Aromatic Hydrocarbons (PAHs) are revealed in astrophysical environments thanks to their characteristic infrared emission after these molecules are subjected to the vacuum ultraviolet (VUV) radiation from nearby massive stars. This interaction regulates their charge state, stability and dissociation mechanisms, which in turn affect the energy balance and the chemistry of the gas in the interstellar medium. In particular, PAHs could contribute to the formation of the most abundant molecule, H2, in photodissociation regions (PDRs). This work aims at contributing to these topics by quantifying the VUV photoprocessing of specific medium-sized PAH cations through experimental studies complemented by computational investigations.The experimental results were gathered from two campaigns at synchrotron facilities: ion trap experiments allowed us to obtain the yields of ionization and fragmentation and the branching ratios between the different photoevents, while from iPEPICO spectroscopy we obtained breakdown curves and RRKM-fitted dissociation rates. We detail the case of the fragmentation processes of two isomers of dibenzopyrene cation (C24H14+) in order to assess the impact of structure on these processes. We present Density Functional Theory calculations and Molecular Dynamics simulations, which evidence the relevance of structure and planarity in these mechanisms and provide a better view on the dissociation pathways and energetics.This work brings significant new data for models that describe the chemical evolution of PAHs in astrophysical environments, including the first measurement of the ionization yield of medium-sized PAH cations as well as several dissociation rates. We also report a new mechanism, involving specific structures with bay areas, that would need to be considered while evaluating the contribution of PAHs to the formation of H2 in PDRs.

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).

Ve la luz el documental “Nanocosmos: un viaje a lo pequeño”


El documental, que cuenta en formato road-movie los entresijos del nacimiento de los granos de polvo en el espacio, está financiado por la Fundación Española para la Ciencia y la Tecnología – Ministerio de Economía, Industria y Competitividad y el Consejo Superior de Investigaciones Científicas (CSIC) y ha sido producido por la empresa LuzLux.

Tras seis meses de trabajo, el equipo formado por personal de CSIC y la productora LuzLux, entre otros, ha finalizado el documental “Nanocosmos: un viaje a lo pequeño”, una película de carretera que habla del reto tecnológico y humano que hay tras el desarrollo de instrumentación en el área de la astrofísica de laboratorio.

La historia se desarrolla en tres planos: el viaje del equipo de grabación desde Madrid hasta Toulouse, los experimentos de laboratorio explicados por sus responsables y el propio viaje de los granos de polvo cósmico desde que nacen en la envoltura de una estrella evolucionada hasta que pasan a formar parte de algo mucho más grande (una estrella, un planeta o, por qué no, un ser vivo).

Este trabajo quiere transmitir las expectativas de los equipos que luchan por comprender este proceso, el reto tecnológico y humano que supone construir máquinas complejas y lograr reproducir en un laboratorio lo que ocurre en el espacio. El documental, de 40 minutos de duración, circulará por circuitos de cine científico y canales específicos de divulgación científica durante un año, tras lo que estará disponible en la página web de Nanocosmos.

En este enlace podrán ver el tráiler que anuncia el documental, que está disponible en español  con subtítulos en inglés y en francés. También hay una versión con subtítulos en español para personas con discapacidad auditiva.


After six months of work, the team formed by CSIC staff and the LuzLux production company, among others, has completed the documentary “Nanocosmos, un viaje a lo pequeño” (a journey to the origins of dust grains), a road movie which talks about the technological and human challenge that lies behind the development of instruments in the area of Laboratory Astrophysics.

The story unfolds in three levels: the journey of the recording team from Madrid (Spain) to Toulouse (France), the laboratory experiments explained by its principal investigators and the journey of the cosmic dust grains since they are born in the envelope of an evolved star until they become part of something bigger (a star, a planet or, why not, a living being).

This work wants to transmit the expectations of the teams struggling to understand this process, the technological and human challenge involved in building complex machines whith a goal: to reproduce in a laboratory what happens in space. The 40-minute documentary will circulate along circuits of scientific movies and specific science channels for a year, and after that it will be available on the Nanocosmos’ website.

In this link you can see the trailer announcing the documentary. The movie is available in Spanish with subtitles in English and French.

Detecting the building blocks of aromatics” is the title of this “Insight” written by Christine Joblin and José Cernicharo (both NANOCOSMOS PIs together with J.A. Martín Gago) and talking about the history and importance of the work published by Brett A. McGuire et al. (“Detection of the aromatic molecule benzonitrile (c-C6H5CN) in the interstellar medium“) in the “Science Magazine” (12/01/2018).

This is the summary of the article from C. Joblin and J. Cernicharo:

“Interstellar clouds are sites of active organic chemistry. Many small, gasphase molecules are found in the dark parts of the clouds that are protected from ultraviolet (UV) photons, but these molecules photodissociate in the external layers of the cloud that are exposed to stellar radiation (see the photo). These irradiated regions are populated by large polycyclic aromatic hydrocarbons (PAHs) with characteristic infrared (IR) emission features. These large aromatics are expected to form from benzene (C6H6), which is, however, difficult to detect because it does not have a permanent dipole moment and can only be detected via its IR absorption transitions against a strong background source (2). On page 202 of this issue, McGuire et al. (3) report the detection of benzonitrile (c-C6H5CN) with radio telescopes. Benzonitrile likely forms in the reaction of CN with benzene; from its observation, it is therefore possible to estimate the abundance of benzene itself”.

‘Estrella’, a comic inspired by Nanocosmos

homepage-banner-estrella-1The first chapter of ‘Estrella’ is out!

‘Estrella’ is a comic developed by an ERC proyect called ERCcOMIC and inspired by Nanocosmos. As the comic team believes in the power of visual storytelling, they illustrate each in a concrete, memorable and engaging way, drawing inspiration from science through stories and images.

The story of ‘Estrella’, by the artist Lorenzo Palloni, is set in 2106, and mankind is radically evolving. The NANOCOSMOS project has changed the path of astrochemistry and astrophysics, and now is the time for an elderly Estrella Leroux to pass the torch to three young scientists. Yet the story of an impossible journey of a young Estrella as a child inside the “Stardust” (a groundbreaking machine that reproduces the processes of a dying star) calls everything into question. The three budding stargazers will discover that their destiny is bound up with the mysterious Estrella’s, on the border between a surprising past and a never-so-uncertain future!

Don’t miss the story of Estrella and enjoy!
