Molecular Clusters in gas and liquid phases

Our research group contributes in development of theoretical approaches, far beyond simplified models, and the design of specific computational tools to address efficiently real problems of physicochemical interest in the field that links science to technology and innovation. The main goal is the detailed understanding of a variety of molecular processes through quantum dynamics simulations. Our investigation focuses on the study of reactive collisions, large helium clusters doped with impurities, quantum molecular processes in nanoconfined systems and hydration effects in aqueous solutions. Our activities cooperate to build a proper environment for training young researchers and foster well-established collaborations ensuring progress in scientific knowledge/transfer.

Investigadores del IFF profundizan en los secretos de los polarones

Nuestros compañeros, Dra. María del Pilar de Lara-Castells y Prof. Salvador Miret Artés, lideran una investigación sobre los polarones y sus interacciones en diversos materiales con átomos cercanos. Su trabajo ha sido recientemente publicado en la revista de la Sociedad Europea de Física, "Europhysics News: Quantum Technology". Su trabajo abrirá un abanico científico y tecnológico en el campo de las ciencias sub-nanométricas. En concreto, el estudio amplia nuestros conocimientos fundamentales sobre el comportamiento de los polarones en la superficie de distintos materiales (TiO2), mediante la observación de fonómenos de polarización que surgen de efectos químico cuánticos. Así mismo, muestran la [...]

Atom scattering as a probe of the surface electron-phonon interaction at conducting surfaces

Authors: Manson, J. R.; Benedek, G.; Miret-Artés, S. Journal: SURFACE SCIENCE REPORTS Publication date: 2022/05/01 DOI: 10.1016/j.surfrep.2022.100552 Abstract: An atomic projectile colliding with a surface at kinetic energies in the thermal or hyperthermal range interacts with and is reflected by the electronic density well in front of the first layer of target atoms, and it is generally accepted that the repulsive interaction potential is proportional to the density of electrons extending outside the surface. This review develops a complete treatment of the elastic and inelastic scattering of atoms from a conducting surface in which the interaction with the electron density [...]

Delving into guest-free and He-filled sI and sII clathrate hydrates: a first-principles computational study

Authors: Yanes-Rodríguez, R.; Cabrera-Ramírez, A.; Prosmiti, R. Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/06/01 DOI: 10.1039/d2cp00701k Abstract: The dynamics of the formation of a specific clathrate hydrate as well as its thermodynamic transitions depend on the interactions between the trapped molecules and the host water lattice. The molecular-level understanding of the different underlying processes benefits not only the description of the properties of the system, but also allows the development of multiple technological applications such as gas storage, gas separation, energy transport, etc. In this work we investigate the stability of periodic crystalline structures, such as He@sI and He@sII [...]

Lithium ions solvated in helium

Authors: Monisha Rastogi, Christian Leidlmair, Lukas An der Lan, Josu Ortiz de Zárate, Ricardo Pérez de Tudela, Massimiliano Bartolomei, Marta I. Hernández, José Campos-Martínez, Tomás González-Lezana, Javier Hernández-Rojas, José Bretón, Paul Scheiera and Michael Gatchell. Contribution: Article Journal: Phys. Chem. Chem. Phys. Publication date: 28 25569-25576 (2018) DOI: 10.1039/C8CP04522D Abstract: We report on a combined experimental and theoretical study of Li+ ions solvated by up to 50 He atoms. The experiments show clear enhanced abundances associated with HenLi+ clusters where n = 2, 6, 8, and 14. We find that classical methods, e.g. basin-hopping (BH), give results that qualitatively agree with quantum mechanical methods such as path [...]

Electron–Phonon Coupling Constant of Metallic Overlayers from Specular He Atom Scattering

Authors: G. Benedek, Salvador Miret-Artés, J. P. Toennies and J. R. Manson. Contribution: Article Journal: J. Phys. Chem. Lett. Publication date: 76-83 (2018) DOI: 10.1021/acs.jpclett.7b03047 Abstract: He atom scattering has been shown to be a sensitive probe of electron–phonon interaction properties at surfaces. Here it is shown that measurements of the thermal attenuation of the specular He atom diffraction peak (the Debye–Waller effect) can determine the electron–phonon coupling constant, λ, for ultrathin films of metal overlayers on various close-packed metal substrates. Values of λ obtained for single and multiple monolayers of alkali metals, and for Pb layers on Cu(111), extrapolated to [...]

A Systematic Protocol for Benchmarking Guest–Host Interactions by First‐Principles Computations: Capturing CO2 in Clathrate Hydrates

Authors: Dr. Daniel J. Arismendi‐Arrieta, Dr. Álvaro Valdés, Dr. Rita Prosmiti. Contribution: Article Journal: Chem. Eur. J. Publication date: 24, 9353-9363 (2018). DOI: 10.1002/chem.201800497 Abstract: Clathrate hydrates of CO2 have been proposed as potential molecular materials in tackling important environmental problems related to greenhouse gases capture and storage. Despite the increasing interest in such hydrates and their technological applications, a molecular‐level understanding of their formation and properties is still far from complete. Modeling interactions is a challenging and computationally demanding task, essential to reliably determine molecular properties. First‐principles calculations for the CO2 guest in all sI, sII, and sH clathrate cages were performed, [...]
