A 19F Solvatomagnetic Comparison Method for the Determination of the α1 Scale of Solvent Hydrogen‐Bond Donation and Its Application to Deep Eutectic Solvents

Journal of Physical Organic Chemistry, Volume 38, Issue 1, January 2025.
A single 19F NMR spectrum of a solution of 4‐fluoro‐2‐methylpyridine and of 4‐fluoronitrobenzene yields the hydrogen‐bond donation parameter α1 of the solvent, through the solvatomagnetic comparison method. ABSTRACT We develop a nonsolvatochromic comparison method for the determination of the α1 scale of solvent hydrogen‐bond acidity by means of 19F ...

A detailed mathematical model of the human atrial cardiomyocyte: integration of electrophysiology and cardiomechanics

The Journal of Physiology, Volume 602, Issue 18, Page 4543-4583, 15 September 2024.
Abstract figure legend Three phases of novel human atrial electromechanically coupled model, MBS2023. Phase 1 deals with model development, the conceptual background, and the coupling of forward and backward pathways. Phase 2 is based on calibration of parameters related to contraction, stretch activated channels, and Ca2+ handling.
