Highligted Scientific Contributions from Our Members:
Low gas consumption fabrication of3 He solid targets for nuclear reactions
Author: Asunción Fernández, Dirk Hufschmidt, Julien L.Colaux, Jose Javier Valiente-Dobón, Vanda Godinho, Maria C.Jiménez de Haro, David Feria, Andrés Gadea, Stéphane Lucas
Materials & Design (2020)
Nanoporous solids that stabilize trapped gas nanobubbles open new possibilities to fabricate solid targets for nuclear reactions. A methodology is described based on the magnetron sputtering (MS) technique operated under quasistatic flux…
Face dependent footprints of carpet-like graphene films grown on polycrystalline silicon carbide
Author: C. Ramírez, E. García, E. Barrena, A. De Pablos, M. Belmonte, M. I. Osendi, P. Miranzo, C. Ocal
Carbon (2019)
Continuous epitaxial graphene (EG) films have been grown on polished surfaces of dense polycrystalline SiC ceramics by heating in a Spark Plasma Sintering furnace (SPS). The confining of the sample into a graphite die and the use of a high…
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
Author: Lidia Martínez, Gonzalo Santoro, Pablo Merino, Mario Accolla, Koen Lauwaet, Jesús Sobrado, Hassan Sabbah, Ramón J. Pelaez, Victor J. Herrero, Isabel Tanarro, Marcelino Agúndez, Alberto Martín-Jimenez, Roberto Otero, Gary J. Ellis, Christine Joblin, José Cernicharo and José A. Martín-Gago
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…
