Kinetics and Thermodynamics of Tautomerization Reactions of 1,1‐ and 1,2‐Ethenediols

International Journal of Chemical Kinetics, Volume 57, Issue 12, Page 687-696, December 2025.
ABSTRACT Tautomerism is a common phenomenon amongst organic molecules with easily interconvertible isomers, which can impact drug action and toxicity. Here we are interested in the enols of carboxylic acids, which are known to be much less stable than their acid counterparts.

Dynamics of Vector Soliton Singlets and Pairs in Self‐Mode‐Locked Tm‐Doped Fibre Lasers

Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
This study characterises soliton build‐up dynamics in a self‐mode‐locked Tm‐doped fibre laser, where both cavity birefringence and distributed saturable absorber play significant roles in the intracavity pulse shaping. The recorded single‐shot spectra using the dispersive Fourier transform technique reveal intensity‐dependent temporal splitting of ...

Acoustic waves interacting with non–locally reacting surfaces in a Lagrangian framework

Mathematische Nachrichten, Volume 298, Issue 12, Page 3855-3892, December 2025.
Abstract The paper deals with a family of evolution problems arising in the physical modeling of small amplitude acoustic phenomena occurring in a fluid, bounded by a surface of extended reaction. They are all derived in a Lagrangian framework. We study well‐posedness of these problems, their mutual relations, and their relations with other evolution ...

Spectral Density Function Analysis Reveals Coupled Relaxation and Resonance Modes in Fluorinated Elastomers: Comparison With Semicrystalline Poly(tetrafluoroethylene)

Magnetic Resonance in Chemistry, Volume 63, Issue 12, Page 1075-1082, December 2025.
We used static‐gradient 19F NMR imaging to compare molecular dynamics in semicrystalline polytetrafluoroethylene (PTFE) and amorphous fluorinated elastomer films. PTFE shows depth‐dependent motion, while the elastomer exhibits uniform dynamics with resonance‐like peaks in its spectral density, suggesting intrinsic vibrational modes.
