Highligted Scientific Contributions from Our Members:
Fluorescent bicolour sensor for low-background neutrinoless double β decay experiments
Author: Iván Rivilla, Borja Aparicio, Juan M. Bueno, David Casanova, Claire Tonnelé, Zoraida Freixa, Pablo Herrero, Celia Rogero, José I. Miranda, Rosa M. Martínez-Ojeda, Francesc Monrabal, Beñat Olave, Thomas Schäfer, Pablo Artal, David Nygren, Fernando P. Cossío & Juan J. Gómez-Cadenas
Observation of the neutrinoless double β decay is the only practical way to establish that neutrinos are their own antiparticles1. Because of the small masses of neutrinos, the lifetime of neutrinoless double β decay is expected to be at least ten orders of magnitude….
Generation and Imaging of Magnetoacoustic Waves over Millimeter Distances
Author: Blai Casals, Nahuel Statuto, Michael Foerster, Alberto Hernández-Mínguez, Rafael Cichelero, Peter Manshausen, Ania Mandziak, Lucía Aballe, Joan Manel Hernàndez, and Ferran Macià
Using hybrid piezoelectric-magnetic systems we have generated large amplitude magnetization waves mediated by magnetoelasticity with up to 25 degrees variation in the magnetization orientation. We present direct imaging and quantification of both standing...
Experimental and Theoretical Investigation on the OH + CH3C(O)CH3 Reaction at Interstellar Temperatures (T = 11.7–64.4 K)
Author: Sergio Blázquez, Daniel González, Alberto García-Sáez, María Antiñolo, Astrid Bergeat, Françoise Caralp, Raphaël Mereau, André Canosa, Bernabé Ballesteros, José Albaladejo, and Elena Jiménez
The rate coefficient, k(T), for the gas-phase reaction between OH radicals and acetone CH3C(O)CH3, has been measured using the pulsed CRESU (French acronym for Reaction Kinetics in a Uniform Supersonic Flow) technique (T = 11.7–64.4 K). The temperature dependence...
Conformational impact of aliphatic side chains in local anaesthetics: benzocaine, butamben and isobutamben
Author: A. Insausti, C. Calabrese, M. Parra, I. Usabiaga, M. Vallejo-López, P. Écija, F. J. Basterretxea, J.-U. Grabow, W. Caminati, A. Lesarri and E. J. Cocinero
We studied the impact of aliphatic side chains on the stability and conformational landscape of the local anaesthetics benzocaine, butamben and isobutamben, combining high-resolution rotational spectroscopy in the microwave and millimetre regions and molecular modelling...
The Chemistry of Cosmic Dust Analogs from C, C2, and C2H2 in C-rich Circumstellar Envelopes
Author: Gonzalo Santoro, Lidia Martínez, Koen Lauwaet, Mario Accolla, Guillermo Tajuelo-Castilla, Pablo Merino, Jesús M. Sobrado, Ramón J. Peláez, Víctor J. Herrero, Isabel Tanarro
Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch stars (AGBs). In these highly chemically stratified regions, atomic and diatomic carbon, along with acetylene, are the most abundant...
Combining high temperature sample preparation and in-situ magnetic fields in XPEEM
Authors: Anna Mandziaka, Juan de la Figuera, Jose Emilio Prieto, Jordi Prata, Michael Foerster, Lucía Aballe
We present a custom-made sample holder system for use in Elmitec Low Energy and PhotoEmission Electron Microscopes. It consists of two different sample holder bodies: one with a filament for high temperature measurements (up to more than 1500 K) and the other with integrated electromagnets...
Molecular Approach for Engineering Interfacial Interactions in Magnetic/Topological Insulator Heterostructures
Authors: Marc G. Cuxart, Miguel Angel Valbuena, Roberto Robles, César Moreno, Frédéric Bonell, Guillaume Sauthier, Inhar Imaz, Heng Xu, Corneliu Nistor, Alessandro Barla, Pierluigi Gargiani, Manuel Valvidares, Daniel Maspoch, Pietro Gambardella, Sergio O. Valenzuela, and Aitor Mugarza
Controlling interfacial interactions in magnetic/topological insulator heterostructures is a major challenge for the emergence of novel spin-dependent electronic phenomena....
Experimental determination of surface thermal expansion and electron–phonon coupling constant of 1T-PtTe2
Author: Gloria Anemone, Manuela Garnica, Marilena Zappia, Pablo Casado Aguilar, Amjad Al Taleb, Chia-Nung Kuo, Chin Shan Lue, Antonio Politano, Giorgio Benedek, Amadeo L Vázquez de Parga
, , (2020)
We report an extensive structural characterization of the surface of 1T-PtTe2 crystals by means of helium atom scattering (HAS) and ultra-high resolution scanning tunnelling microscopy (STM). HAS reveals that this bi-dimensional surface presents a large structural corrugation….
Engineering nanostructured cell micropatterns on Ti6Al4V by selective ion-beam inhibition of pitting
Author: R.López, M.D.Ynsa, P.J.de Pablo, F.Lim, M.Manso Silván
Corrosion Science. 9 February 2020, 108528
We have modified Ti6Al4V at the micro and nanoscale by using ion beam irradiation with 5 MeV Si+ ions through 1D micromasks. The passivation layer on irradiated areas inhibits hydrofluoric acid induced etching, leading to pitting contrasts…
