2D metal-organic layer covers gold substrate
Molecular networks provide new surface functionality and could enable the formation of more complex structures Nanoporous molecular systems have become an interesting field. They are well reported as templates for positioning nano-objects and for having remarkable applications in catalysis. Now metal-organic monolayers can be grown in a controlled way using…
Fullerene on Google Homepage
Twenty-five years ago today, on September 4, 1985, the buckyball was discovered at Rice University, and Google is commemorating that scientific discovery with an interactive doodle logo on its homepage El sábado 4 de Septiembre, Google ha colocado en su página de inicio un nuevo logotipo -mejor conocido como “doodle”-,…

fiesta ESISNA-2010
Como ya viene siendo habitual, cada año, antes del verano, nos reunimos los integrantes del grupo junto con nuestros colegas del CAB y antiguos miembros en el campo para hacer una barbacoa a la hora de comer y luego, por la tarde, una fiesta en la que están invitados todos…
Interplay between fast diffusion and molecular interaction in the formation of self-assembled nano-structures of S-Cysteine on Au(111)
Fast diffusing cysteine molecules on the Au surface can be regarded as a 2D molecular gas. Molecular “evaporation” and “condensation” from the gas on the surface morphological features takes place continuously. This process leads progressively to the formation of a number of stable arrangements, not previously reported, like single-molecular rows,…
el Azul de Prusia y el origen de la vida
Un equipo de investigadores del Centro de Astrobiología (INTA-CSIC) ha comprobado que a partir de la sal Azul de Prusia se pueden obtener cianuro de hidrógeno, urea y otras sustancias consideradas esenciales en la formación de las primeras moléculas biológicas. Para realizar el estudio, publicado en la revista Chemistry &…
Single-molecule wires out of single-molecule magnets
A single molecular magnet (SMM) is a large molecule exhibiting superparamagnetic properties, and therefore it behaves like a magnet. One of the challenges attracting more attention over the last few years has been the development of new techniques that allow their nanostructuration and addressing on surfaces, to promote their potential…
Alhambra in ACSIN-10
Most of the people of the ESISNA group have attended to the international conference: «Atomic controlled surfaces and interfaces- ACSIN» held in Granada (September-2009). The conference was mainly devoted to discuss about epitaxial graphene layers and organic molecules on surfaces.After the long scientific sessions we found also time for visiting…

TiO2: How to prepare a good surface.
Surface Science studies use to prepare flat and clean surfaces by combining cycles of sputtering and annealing under Ultra-High Vacuum conditions. This procedure leads to large and ordered atomic terraces, as the shown in the image. However, there are other simple methods to have single-atom separated terraces. These could be…
