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.

Physically Unclonable Functions Based on Single-Walled Carbon Nanotubes: A Scalable and Inexpensive Method toward Unique Identifiers
Author: Enrique Burzurí, Daniel Granados, Emilio M. Pérez
ACS Appl. Nano Mater. (2019
A physically unclonable function (PUF) is a physical system that cannot be reproduced or predicted and therefore is a good basis on which to build security and anticounterfeiting applications. The unclonability of PUFs typically stems from the randomness induced…
Liquid switchable radial polarization converters made of sculptured thin films
Author: ManuelOliva-Ramírez, Victor J.Rico, JorgeGil-Rostra, OriolArteaga, EnricBertran, RosalíaSerna, Agustín R.González-Elipe, Francisco Yubero
Applied Surface Science (2019)
A radial polarization converter is a super-structured optical retarder that converts a conventional linearly polarized light beam into a structured beam with radial or azimuthal polarization. We present a new type of these sophisticated optical elements, which is made of porous nanostructured…
Prevalence of non-aromatic carbonaceous molecules in the inner regions of circumstellar envelopes

Nature Astronomy (2019)
Evolved stars are foundries of chemical complexity, gas and dust that provide the building blocks of planets and life, and dust nucleation first occurs in their photosphere. The circumstellar regions enveloping these…
Plasma Enabled Conformal and Damage Free Encapsulation of Fragile Molecular Matter: from Surface‐Supported to On‐Device Nanostructures
Author: Maria Alcaire, Francisco J. Aparicio, José Obrero, Carmen López‐Santos, Francisco J. Garcia‐Garcia, Juan R. Sánchez‐Valencia, Fabián Frutos, Kostya (Ken) Ostrikov, Ana Borrás, Angel Barranco.
Advanced Functional Materials 2019
Damage‐free encapsulation of molecular structures with functional nanolayers is crucial to protect nanodevices from environmental exposure. With nanoscale electronic, optoelectronic, photonic, sensing, and other nanodevices based on atomically thin and fragile organic matter shrinking…
Strontium hexaferrite platelets: a comprehensive soft X-ray absorption and Mössbauer spectroscopy study
Author: G. D. Soria, P. Jenus, J. F. Marco, A. Mandziak, M. Sanchez-Arenillas, F. Moutinho, J. E. Prieto, P. Prieto, J. Cerdá, C. Tejera-Centeno, S. Gallego, M. Foerster, L. Aballe, M. Valvidares, H. B. Vasili, E. Pereiro, A. Quesada, and J. de la Figuera.
Scientific Reports. 2019
Platelets of strontium hexaferrite (SrFe12O19, SFO), up to several micrometers in width, and tens of nanometers thick have been synthesized by a hydrothermal method. They have been studied by a combination of structural and magnetic techniques, with emphasis on Mössbauer…
