Statistical Characterization of Joule Heating Associated With Ionospheric ULF Perturbations Using SuperDARN Data

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract Ultra low frequency (ULF; 1 mHz ‐ several Hz) waves are key to energy transport within the geospace system, yet their contribution to Joule heating in the upper atmosphere remains poorly quantified. This study statistically examines Joule heating associated with ionospheric ULF perturbations using Super Dual Auroral Radar Network (SuperDARN ...

Racionamiento en garantía y relación bancaria de las pymes en España

open access: yesInnovar: Revista de Ciencias Administrativas y Sociales, 2016
La incidencia de la relación bancaria en el racionamiento de crédito de las pymes ha sido ampliamente analizada en la literatura, aunque el análisis del racionamiento en garantía es, tal vez, el que menor atención ha recibido.

Reduced Non‐Specific Binding of Super‐Resolution DNA‐PAINT Markers by Shielded DNA‐PAINT Labeling Protocols

open access: yesSmall, Volume 20, Issue 51, December 19, 2024.
Conventional immunohistochemistry labeling with oligonucleotide conjugated secondary antibodies can lead to significant non‐specific uptake across biological cells and is especially prominent within the nucleus. By adding a pre‐incubation step with fully or partially complementary strands and increasing the ionic strength of the buffer this non ...

Trispyrazolyl Borate Iron Thiolate Complexes and the Dependence of their O2‐Reactivity on the Reaction Space

open access: yesEuropean Journal of Inorganic Chemistry, Volume 27, Issue 29, October 11, 2024.
Trispyrazolyl borato iron(II) thiolates have been investigated with regard to their O2 reactivity. The influence of the steric and electronic situation around the iron center as well as the effect of an additional donor function as part of the scorpionate ligand on the selectivity are evaluated. Abstract The work presented here investigates whether the

Chirality Generated by Hindered Rotations in Platinum(II)‐Pyridine Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 27, Issue 3, January 22, 2024.
A series of Pt(II) complexes with 2‐alkylsubstituted pyridines display planar chirality due to the influence of the pyridine substituent, which enhances the rotational barrier around the Pt–N bond generating a couple of enantiomers. The chiral conformation is also stabilized by the presence of an axial Pt⋅⋅⋅H‐C interaction.
