The Welch Scholarship of the I.U.S.V.T.A.
Scholarship Application Deadline Extended to April 30th 2011 The Welch Scholarship provides $15000 support once per year to a promising scholar who wishes to study vacuum science, techniques or their application in any field, and wants to spend a year in a research lab in another country. This is an…
Surfaces: Magic wands for molecular transformations
New bottom-up strategies for molecular assembly to tailor-build new molecules The appearance on the technological scene of new electronic devices based on organic molecules is awaited with much expectation since they promise to be inexpensive, flexible, faster and smaller than those based on silicon technology. However, molecular electronics faces important…
An atomistic view of the the enantiomeric recognition of PAHs on single crystal metal surfaces
Recently published in Chemistry, a European Journal. Vacuum deposition of a planarized PAH, as C60H30 , on a single-crystal surface, as Pt(111), leads to surface induced chirality caused by the different landing side of the molecule, as depicted by in-situ STM images. We show that the surface discriminate the landing…
Ordered Vacancy Network Induced by the Growth of Epitaxial Graphene on Pt(111)
Published in Phys. Rev. Lett. by ESISNA Graphene is one of the most outstanding materials of the decade. Among all the different proposed applications and protocols to growth it, epitaxial graphene on single-crystal metal surfaces have acquired a significant relevance as a model system where to rationalize their atomic structure,…
How are the STM images influenced by structural changes in the tip?
What you see it is not what it is! Chemical and morphological changes in the tip are frequent during an experimental STM session. We have shown the effect of different tip apexes on the appearance of atomic features of STM images by relating experimental STM images with DFT calculations. The…
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,…
