Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

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

ChemPhysChem, 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

Properties of Bisdiazo Compounds and Their Derived Carbenes via Density Functional Theory

ChemPhysChem, EarlyView.
Density function theory (DFT) calculation at level of B3LYP‐(D3)BJ/6‐311G** reveals the fundamental electronic structure of substituted bisdiazo compounds as well as their derived carbene and biscarbene species at both ground and excited states. Extension to physisorption onto single‐layer graphene provides more insight of the surface behaviour of this

Do Firms Hoard Cash Under Environmental Pressure? Insights From GHG Emissions and Greenwashing Activities

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Environmental accountability has become a global priority, with governments implementing policies like the Kyoto Protocol and the Paris Agreement. However, many firms continue to operate outside environmentally ethical standards, facing potential regulatory, financial, and reputational risks.
