Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Nonlinear internal gravity waves in the atmosphere: Rogue waves, breathers and dark solitons

open access: yesCommunications in Nonlinear Science and Numerical Simulation
We study nonlinear internal gravity waves (IGWs) in the atmosphere. The reductive perturbation method is used to derive a system of two-dimensional nonlinear equations for the envelope of velocity stream function and the mean flow. In the one-dimensional case, we obtain a nonlinear Schrödinger (NLS) equation corresponding to both horizontal and ...

Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...
