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...
Mimicking the Martian Hydrological Cycle: A Set-Up to Introduce Liquid Water in Vacuum
Liquid water is well known as the life ingredient as a solvent. However, so far, it has only been found in liquid state on this planetary surface. The aim of this experiment and technological development was to test if a moss sample is capable of survivin….
Multilayer passive radiative selective cooling coating based on Al/SiO2/SiNx/SiO2/TiO2/SiO2 prepared by dc magnetron sputtering
A multilayer passive radiative selective cooling coating based on Al/SiO2/SiNx/SiO2/TiO2/SiO2 prepared by dc magnetron sputtering is presented. The design was first theoretically optimized using the optical constants...
Gas-phase kinetics of CH3CHO with OH radicals between 11.7 and 177.5 K
Gas-phase reactions in the interstellar medium (ISM) are a source of molecules in this environment. The knowledge of the rate coefficient for neutral–neutral reactions as a function of temperature, k(T), is essential to improve...
