Natural layered phlogopite dielectric for ultrathin two-dimensional optoelectronics
Thomas Pucher, Julia Hernandez-Ruiz, Guillermo Tajuelo-Castilla +3
The integration of high-dielectric-constant (high-) materials with two-dimensional (2D) semiconductors is promising to overcome performance limitations and reach their full theo…
Atmospheric molecular blobs shape up circumstellar envelopes of AGB stars
L. Velilla-Prieto, J. P. Fonfría, M. Agúndez +8
During their thermally pulsing phase, Asymptotic Giant Branch (AGB) stars eject material that forms extended dusty envelopes. Visible polarimetric imaging found clumpy dust clouds…
Few-layer antimonene electrical properties
Pablo Ares, Sahar Pakdel, Irene Palacio +10
Antimonene -- a single layer of antimony atoms -- and its few layer forms are among the latest additions to the 2D mono-elemental materials family. Numerous predictions and experim…
INFRA-ICE: an ultra-high vacuum experimental station for laboratory astrochemistry
Gonzalo Santoro, Jesús. M. Sobrado, Guillermo Tajuelo-Castilla +7
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 as…
Silicon and hydrogen chemistry under laboratory conditions mimicking the atmosphere of evolved stars
Mario Accolla, Gonzalo Santoro, Pablo Merino +10
Silicon is present in interstellar dust grains, meteorites and asteroids, and to date thirteen silicon-bearing molecules have been detected in the gas-phase towards late-type stars…
The chemistry of cosmic dust analogues from C, C, and CH in C-rich circumstellar envelopes
Gonzalo Santoro, Lidia Martínez, Koen Lauwaet +13
Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch (AGB) stars. In these highly chemical…
Chemical equilibrium in AGB atmospheres: Successes, failures, and prospects for small molecules, clusters, and condensates
M. Agundez, J. I. Martinez, P. L. de Andres +2
Chemical equilibrium has proven extremely useful to predict the chemical composition of AGB atmospheres. Here we use a recently developed code and an updated thermochemical databas…
Tailored Graphenic Structures Directly Grown on Titanium Oxide Boost the Interfacial Charge Transfer
Roberto Munoz, Carlos Sanchez-Sanchez, Pablo Merino +7
The successful application of titanium oxide-graphene hybrids in the fields of photocatalysis, photovoltaics and photodetection strongly depends on the interfacial contact between…
On-Surface Hydrogen-Induced Covalent Coupling of Polycyclic Aromatic Hydrocarbons via a Superhydrogenated Intermediate
Carlos Sánchez-Sánchez, José Ignacio Martínez, Nerea Ruiz del Arbol +5
The activation and subsequent covalent coupling of polycyclic aromatic hydrocarbons (PAHs) are of great interest in fields like chemistry, energy, biology, or health, among others.…
Versatile Graphene-Based Platform for Robust Nanobiohybrid Interfaces
Rebeca Bueno, Marzia Marciello, Miguel Moreno +16
Technologically useful and robust graphene-based interfaces for devices require the introduction of highly selective, stable, and covalently bonded functionalities on the graphene…
Structural characterization of as-grown and quasi-free standing graphene layers on SiC
R. A. Bueno, I. Palacio, C. Munuera +6
We report on a comparative structural characterization of two types of high quality epitaxial graphene layers grown by CVD on 4H-SiC(0001). The layers under study are a single laye…
Using radio astronomical receivers for molecular spectroscopic characterization in astrochemical laboratory simulations: A proof of concept
I. Tanarro, B. Alemán, P. de Vicente +26
We present a proof of concept on the coupling of radio astronomical receivers and spectrometers with chemical reactorsand the performances of the resulting setup for spectroscopy a…
Identification of PAH Isomeric Structure in Cosmic Dust Analogues: the AROMA setup
Hassan Sabbah, Anthony Bonnamy, Dimitris Papanastasiou +3
We developed a new analytical experimental setup called AROMA (Astrochemistry Research of Organics with Molecular Analyzer) that combines laser desorption/ionization techniques wit…
The growth of carbon chains in IRC+10216 mapped with ALMA
M. Agundez, J. Cernicharo, G. Quintana-Lacaci +9
Linear carbon chains are common in various types of astronomical molecular sources. Possible formation mechanisms involve both bottom-up and top-down routes. We have carried out a…
Formation of Hydrocarbons from Hydrogenated Graphene in Circumstellar Clouds
Jose I. Martinez, Jose A. Martin-Gago, Jose Cernicharo +1
We describe a mechanism that explains the formation of hydrocarbons and hydrocarbyls from hydrogenated graphene/graphite; hard C-C bonds are weakened and broken by the synergistic…
