Single‐Atom‐Dispersed FeNC/FeS2 Nanocluster for High‐Performance Sodium Metal Battery With Hybrid Electrochemical Behavior

Carbon Energy, EarlyView.
A novel single‐atom‐dispersed S2–FeNC/FeS2 nanocluster heterojunction with unique hybrid electrochemical behavior for suppressing the shuttle effect and promoting the hybrid electrochemical reaction was designed, thus improving the specific capacity and cycling stability.

Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

Carbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

A [3]Rotaxane Containing {Ti7Ga} Rings Linking CuII: Synthesis, Structure, and Spectroscopic Studies

Chemistry – A European Journal, EarlyView.
Extended hybrid inorganic‐organic [2]‐ and [3]‐rotaxanes are reported based on heterometallic rings with threads that link CuII complexes; the crystal structures are reported, and the solution behavior is investigated by double electron electron resonance spectroscopy methods.

Hamiltonian cycles for finite Weyl groupoids

Journal of Algebra and Its Applications
Let [Formula: see text] be the Cayley graph of a finite Weyl groupoid [Formula: see text]. In this paper, we show an existence of a Hamiltonian cycle of [Formula: see text] for any [Formula: see text]. We exactly draw a Hamiltonian cycle of [Formula: see text] for any (resp. some) irreducible [Formula: see text] of rank three (resp. four).

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

Spin‐Crossover Modulated Luminescence in Materials and Molecular Complexes

Helvetica Chimica Acta, EarlyView.
The synergistic coupling of spin‐crossover and luminescent properties holds great promise for the development of multifunctional and stimuli‐responsive molecular materials. This contribution provides a comprehensive overview of the field, surveying the possible coupling mechanisms, the various synthetic strategies and their potential applicability, as ...
