Metallic thin films on stepped surfaces: lateral scattering of quantum well states
(IOP Publishing, 2014-12-10)
Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe ...
The dynamic atmospheric and aeolian environment of Jezero crater, Mars
(American Association for the Advancement of Science, 2022-05)
Despite the importance of sand and dust to Mars geomorphology, weather, and exploration, the processes that move sand and that raise dust to maintain Mars' ubiquitous dust haze and to produce dust storms have not been well ...
AmelHap: Leveraging drone whole-genome sequence data to create a honey bee HapMap
(Nature, 2023-04)
Honey bee, Apis mellifera, drones are typically haploid, developing from an unfertilized egg, inheriting only their queen’s alleles and none from the many drones she mated with. Thus the ordered combination or ‘phase’ of ...
Upgrading Polyurethanes into Functional Ureas through the Asymmetric Chemical Deconstruction of Carbamates
(American Chemical Society, 2023-01)
The importance of systematic and efficient recycling of all forms of plastic is no longer a matter for debate. Constituting the sixth most produced polymer family worldwide, polyurethanes, which are used in a broad variety ...
ænet-PyTorch: A GPU-supported implementation for machine learning atomic potentials training
(AIP, 2023-04)
In this work, we present ænet-PyTorch, a PyTorch-based implementation for training artificial neural network-based machine learning interatomic potentials. Developed as an extension of the atomic energy network (ænet), ...
4,4′-Dicyano- versus 4,4′-Difluoro-BODIPYs in Chemoselective Postfunctionalization Reactions: Synthetic Advantages and Applications
(American Chemical Society, 2023-04)
The presence of F or CN substituents at boron in BODIPYs causes a dramatic effect on their reactivity, which allows their chemoselective postfunctionalization. Thus, whereas 1,3,5,7-tetramethyl B(CN)2-BODIPYs displayed ...
Polyphase tectonic reworking of serpentinites and chlorite-tremolite-talc rocks (SW Spain) from the subduction forearc to intracontinental emplacement
(Wiley, 2023-05)
The petrostructural and geochronological study of a poorly known ultramafic unit from SW Spain (Badajoz–Córdoba belt) combined with previous structural data permits disclosure of a history of metasomatism, tectono-metamorphism, ...
Robust Rules for Optimal Colorimetric Sensing Based on Gold Nanoparticle Aggregation
(American Chemical Society, 2023-04)
Spurred by outstanding optical properties, chemical stability, and facile bioconjugation, plasmonic metals have become the first-choice materials for optical signal transducers in biosensing. While the design rules for ...
A history of the Basque prosodic systems
(John Benjamins, 2023-02)
This paper presents new proposals for the reconstruction of Proto-Basque accentuation, as well as the development and chronology of the main accentual systems of the modern dialects, grounded in phonetic, historical and ...
Mars 2020 Perseverance Rover Studies of the Martian Atmosphere Over Jezero From Pressure Measurements
(American Geophysical Union, 2023-01)
The pressure sensors on Mars rover Perseverance measure the pressure field in the Jezero crater on regular hourly basis starting in sol 15 after landing. The present study extends up to sol 460 encompassing the range of ...
