ASEVA is a non-profit organization founded on 1963 as a specialised working group of the Spanish Committee of the International Union of Pure and Applied Physics (IUPAP). Currently, ASEVA is a member of the IUVSTA (International Union for Vacuum Science, Technique and Applications), where it participates actively.

Liquid atomic layer deposition as emergent technology for the fabrication of thin films
Atomic layer deposition (ALD) is widely recognized as a unique chemical vapor deposition technique for the fabrication of thin films with high conformality…
Sprayable PEDOT:PSS based spectrally selective coating for solar energy harvesting
Authors:N. Selvakumar, G. Karthik, Swetha Jayaraj, Harish C. Barshilia
A novel spectrally selective coating was developed on stainless substrates using commercially available poly(ethylene-3,4-dioxythiophene):poly (styrene sulfonate), (PEDOT:PSS) polymer for solar energy…
In situ XPS analysis of the electronic structure of silicon and titanium thin films exposed to low-pressure inductively-coupled RF plasma
Authors: Jordi Fraxedas, Max Schütte, Guillaume Sauthier, Massimo Tallarida, Salvador Ferrer, Vincent Carlino, Eric Pellegrin
Carbon contamination of synchrotron and free-electron lasers beamline optics continues to be a major nuisance due to the interaction of the intense photon beams with the surfaces of the optical elements…
Particle and rain erosion mechanisms on Ti/TiN multilayer PVD coatings for carbon fibre reinforced polymer substrates protection
Authors: Borja Coto, Per Hallander, Lucía Mendizabal, Francesco Pagano, Hans Kling, Rocío Ortiz, Javier Barriga, Linnéa Selegård
PVD coatings have been studied as candidates for erosion protection of carbon fibre reinforced polymers. Thus, multilayer Ti/TiN coating stacks with different thicknesses ranging from 1.5 to 11 μm have been deposited by…
Vibrational Frequencies of Cerium-Oxide-Bound CO: A Challenge for Conventional DFT Methods
Authors: Pablo G. Lustemberg, Philipp N. Plessow, Yuemin Wang, Chengwu Yang, Alexei Nefedov, Felix Studt, Christof Wöll, and M. Verónica Ganduglia-Pirovano
Abstract: In ceria-based catalysis, the shape of the catalyst particle, which determines the exposed crystal facets, profoundly affects its reactivity. The vibrational frequency of adsorbed carbon monoxide (CO) can be used as a sensitive probe...
Plasma-Enabled Amorphous TiO2 Nanotubes as Hydrophobic Support for Molecular Sensing by SERS
Authors: Nicolas Filippin, Javier Castillo-Seoane, M. Carmen López-Santos, Cristina T. Rojas, Kostya Ostrikov, Angel Barranco, Juan R. Sánchez-Valencia, and Ana Borrás
Abstract: We devise a unique heteronanostructure array to overcome a persistent issue of simultaneously utilizing the surface-enhanced Raman scattering, inexpensive, Earth-abundant materials large surface areas, and multifunctionality to demonstrate near single-molecule detection...
Robust anti-icing superhydrophobic aluminum alloy surfaces by grafting fluorocarbon molecular chains
Authors: VíctorRico, JulioMora, PalomaGarcía, AlinaAgüero, AnaBorrás, Agustín R.González-Elipe, CarmenLópez-Santos
Abstract: Infusion of low surface tension liquids in nanostructured surfaces is currently used to promote an anti-icing response, although the long term stability of these systems is often jeopardized by losses of the infused liquid. In this work, we propose an alternative...
INFRA-ICE: An ultra-high vacuum experimental station for laboratory astrochemistry
Abstract: Laboratory astrochemistry aims at simulating, in the laboratory, some of the chemical and physical processes that operate in different regions of the universe. Amongst the diverse astrochemical problems that can be addressed in the laboratory...
FeCo Nanowire–Strontium Ferrite Powder Composites for Permanent Magnets with High-Energy Products
Authors: J. C. Guzmán-Mínguez, S. Ruiz-Gómez, L. M. Vicente-Arche, C. Granados-Miralles, C. Fernández-González, F. Mompeán, M. García-Hernández, S. Erohkin, D. Berkov, D. Mishra, C. de Julián Fernández, J. F. Fernández, L. Pérez, and A. Quesada
Abstract: Due to the issues associated with rare-earth elements, there arises a strong need for magnets with properties between those of ferrites and rare-earth magnets that could substitute...
Toward the RNA-World in the Interstellar Medium—Detection of Urea and Search of 2-Amino-oxazole and Simple Sugars
Authors: Izaskun Jiménez-SerraJesús Martín-Pintado Víctor M. Rivilla Lucas Rodríguez-Almeida Elena R. Alonso Alonso Shaoshan Zeng Emilio J. Cocinero Sergio Martín Miguel Requena-Torres Rafa Martín-Domenech Leonardo Testi
Abstract: In the past decade, astrochemistry has witnessed an impressive increase in the number of detections of complex organic molecules. Some of these species are of prebiotic interest such as glycolaldehyde...
