Enlace entre dos estrellas de la química: grafeno y porfirina

Artículo de divulgación haciendo referencia al trabajo de Manuela Garnica:

En la actualidad es difícil encontrar un material que atraiga tanto la atracción de científicos e ingenieros como el grafeno, formado por una capa de átomos de carbonos distribuidos en forma hexagonal. Es flexible, extremadamente delgado y transparente, al mismo tiempo que presenta una gran resistencia y conduce la electricidad, unos requisitos ideales para multitud de aplicaciones, especialmente en el campo de la electrónica.

Sin embargo, la utilización del grafeno para captar la energía solar o como sensor de gases requiere de unas propiedades específicas de las que carece; aunque las puede adquirir por medio de la adición o funcionalización con determinadas moléculas.

Un equipo de investigadores de la Universidad Técnica de Múnich (TUM), liderado por el profesor Wilhelm Auwärter, ha conseguido unir a la lámina de grafeno un importante grupo bioquímico: las porfirinas, unos anillos proteicos que forman parte de la clorofila, esencial para la fotosíntesis en las plantas, y de la hemoglobina, encargada de transportar el oxígeno en la sangre de los animales.

“Las nuevas estructuras híbridas pueden llegar a usarse en el campo de la electrónica molecular -donde los circuitos electrónicos están compuestos por unidades moleculares-, así como en procesos catalíticos con los que se aceleran multitud de reacciones químicas, y en el desarrollo de nuevos sensores de gases”, destaca a Sinc la investigadora española Manuela Garnica Alonso, coautora del trabajo en la universidad alemana.

Watch for disingenuous initiatives among the guises of Spanish research activism

The consequences for research of “Spain Brand’s” institutional interests percolating research activities

At the 2017 AAAS meeting, Barbara Schaal, the AAAS President, while talking about the international nature of science, reflected that the US has probably benefited from it more than any other country because it has been able to attract the best and the brightest from the world. “Science in the US flourishes when we allow [them] to come, and to live, and to work here.” For the Spanish government, however, the internationalisation of Spanish science has a remarkably different meaning: it means to maximise the return from European grants and to use science diplomacy to improve the prestige of Spanish science abroad.

In the meantime, the Spanish science system, that was criticised more than 80 years ago by Nobel laureate Santiago Ramón y Cajal for its hermeticism, under-funding, over-regulation and bureaucratic burdens, still suffers from those same ailments which undermine the ability of the country to attract international talent. The latter, however, does not seem to be a major concern for government officials.

Simposio Anual de CERU

Simposio Anual de CERU: del 7-9 de julio en Londres


Para los socios de RSEF (no residentes en UK) tendrán una cuota reducida de £10 y podrán acceder a las ayudas que se otorgan (el deadline para poder pedirlas se ha extendido hasta el 29 de mayo (por venir desde fuera del Reino Unido podrán optar a la ayuda de £75).





El próximo día 22 de abril, coincidienco con el Día Mundial de la Tierra, se celebra la marcha por la ciencia en más de 400 ciudades de todo el mundo. Iniciativa que surge en Estados Unidos como respuesta a la profunda preocupación de científicos y ciudadanos ante la creciente ola de políticas anticientíficas y que se ha extendido por todo el mundo.







How dare you call us diplomats

I never considered myself a diplomat, so it came as a surprise to be labelled as one last month by the Spanish government. Officially, Spanish emigrant scientists like me, forced to leave Spain because of the dire circumstances surrounding research at home, did not previously exist. We were told we were an ‘urban legend’. Now, I learn, not only am I real but I am also part of a deliberate and cunning political strategy by the Spanish government to send scientists overseas to seed international collaboration and to strengthen, not weaken, Spanish science.

Open Readings 2017

Dear Colleagues,

we invite You to the international conference for students of physics and natural sciences – Open Readings 2017, which will take place in Vilnius, Lithuania on 14-17th of March, 2017.

The deadline for registration is 3rd of February. Participants can take part in oral and poster sessions presenting on extensive range of topics. Participation is free of charge. Do not hesitate – register now!

Conference programme consist of oral and poster sessions on extensive range of topics, social events and amazing invited speakers:

  • Xi-Cheng Zhang, University of Rochester, USA
  • Nobel laureate Ben Feringa, University of Groningen, Netherlands
  • Philip Russell, Max Planck Institute for the Science of Light, Germany
  • John Ellis, King’s College London, United Kingdom; CERN
  • Michael Grätzel, École polytechnique fédérale de Lausanne, Switzerland
  • Naomi Halas, Rice University, USA
  • Two more speakers will be announced soon

We believe that such experience is essential for students, especially for those who are seeking a career in science. Our conference is open for any enthusiastic student from all over the world. This year we will gather more than 300 presenters – be one of them!

Please forward this letter and its attachments to the adequate departments and students representatives. We also encourage you to place the attached invitation as a poster on your institution’s notice boards.

IWP/RIXS2017 – International Workshop on Photoionization / Resonant Inelastic X-ray Scattering

Deadline for abstract submission: Jan. 15th 2017

Notification of acceptance for oral/poster contribution: Jan. 31st 2017

Deadline for registration: Feb. 17th 2017


Dear colleagues,

We are pleased to announce that registration for IWP/RIXS2017 is now open. We invite you to register and start planning your travel. Please follow the link:


You can also submit an abstract for an oral (progress report) or poster contribution. Abstract template and related submission information are available at:

Abstracts Submission

The IWP & RIXS workshop series have been organized every three years since 1992, the last three ones were held near Uppsala (Sweden) in 2008, in Las Vegas (US) in 2011 and Erice (Italy) in 2014. The 2017 edition of IWP/RIXS will take place in Aussois, France from the 26th to the 31st of March 2017. Aussois is a beautiful authentic ski resort nested in Savoie in the French Alpes.

The joint IWP/RIXS2017 workshop aims at covering a broad field related to photoionization/RIXS processes on dilute matter: atoms, molecules, ions, transient species, molecular complexes, clusters, nanoparticles and liquid interfaces. Both experimental and theoretical approaches should be covered as well as new methodologies associated with synchrotron radiation and with short-wavelengths and/or short pulses sources such as FELs and HHG. We intend also to foster interfaces with chemistry, life sciences, and nanosciences.

The program will be composed of invited speakers, contributed oral progress reports (selected from abstract) and posters. A list of invited speakers can be found here. The participation of young researchers and students is particularly welcome.

Further scientific and practical information can be found on the workshopwebsite.

Don’t hesitate to ask for any queries at: conf-IWP_RIXS2017@synchroton-soleil.fr

We are looking forward in seeing you in Aussois next March.

On behalf of the IWP/RIXS2017 Organizing Committee,

The 3 co-chairs Alfred Maquet, Laurent Nahon & Marc Simon


NB:  We have tried to maintain registration fees at a very reasonable level and including lodging and food. However, we have limited funding to provide partial financial support for particular cases.
