Ultrafast entanglement switching and singlet-triplet transitions control via structured terahertz pulses
(IOP, 2022)
[EN] Terahertz (THz) vector beams with spatially textured polarization are proposed to steer the spin and spatial distributions of two interacting electrons in a quantum dot. We study theoretically the spatiotemporal ...
Tunnelling times, larmor clock, and the elephant in the room
(Nature Research, 2021-05-11)
[EN] A controversy surrounding the “tunnelling time problem” stems from the seeming inability of
quantum mechanics to provide, in the usual way, a definition of the duration a particle is supposed
to spend in a given ...
Unveiling Five Naked Structures of Tartaric Acid
(Wiley, 2021-08-02)
The unbiased, naked structures of tartaric acid, one of the most important organic compounds existing in nature and a candidate to be present in the interstellar medium, has been revealed in this work for the first time. ...
Analysis of Local and Global Aromaticity in Si3C5 and Si4C8 Clusters. Aromatic Species Containing Planar Tetracoordinate Carbon
(MDPI, 2021-09-25)
The minimum energy structures of the Si3C5 and Si4C8 clusters are planar and contain planar tetracoordinate carbons (ptCs). These species have been classified, qualitatively, as global (π) and local (σ) aromatics according ...
Shape of Testosterone
(American Chemical Society, 2021-07-29)
We have successfully characterized the structure of testosterone, one of the essential steroids, through high-resolution rotational spectroscopy. A single conformer has been detected, and a total of 404 transitions have ...
A comprehensive review of C-S-H empirical and computational models, their applications, and practical aspects
(Elsevier, 2022-06)
[EN] The C-S-H gel is an elusive material. Its variable composition and disordered nature complicate a complete characterization of its atomic structure, and the elaboration of models is key to understanding it. This work ...
Aurrerapenak MALDI-Imaging Masa-Espektrometria teknikan: ehunen lipidoak karakterizatzen
(2019-05-21)
a imagen por espectrometría de masas es u na técnica analítica que permite obtener la distribución espacial de diferentes analitos en superficies. El objetivo de IMS en bioquímica es la de detectar los constituyentes ...
Electronic spectroscopy of propofol, propofol homomers ad their hydratated clusters
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2011-10-07)
As several works suggest, the action of anaesthetics takes place through direct
interaction with membrane receptors. They can interrupt the transmission of the
electrical signal along the neuron´s axon by blocking the ...
Mass spectrometry coupled to imaging techniques: The better the view the greater the challenge
(Frontiers Research Foundation, 2015-01-21)
These are definitively exciting times for membrane lipid researchers. Once considered just as the cell membrane building blocks, the important role these lipids play is steadily being acknowledged. The improvement occurred ...
Aggregation of biological building blocks: a theoretical and spectroscopic study
(2017-06-16)
DNA and proteins are involved in biological processes which make possible life. On the one hand, the four DNA bases constitute the alphabet of life. Their normal appearance includes stacked Watson-Crick pairs in order to ...
