Chiral Phonon–Driven Ultrafast Spin Currents in a Non‐Magnetic Ferroelectric

Advanced Materials, EarlyView.
Broadband terahertz emission spectroscopy shows signatures of ultrafast spin‐current generation in non‐magnetic ferroelectric β$\beta$’‐In2Se3${\rm In}_2{\rm Se}_3$. Reversal of the emitted field upon sample inversion and substitution of Pt with W indicates spin‐Hall‐mediated charge conversion, while polarization‐resolved measurements reveal ...

Geary’s c for Multivariate Spatial Data

Mathematics
Geary’s c is a prominent measure of spatial autocorrelation in univariate spatial data. It uses a weighted sum of squared differences. This paper develops Geary’s c for multivariate spatial data. It can describe the similarity/discrepancy between vectors

Coordination Bridges in Confined‐Water Domains Enable Partially Desolvated Zn2+ Transport in Aqueous Zinc‐Ion Batteries

Advanced Materials, EarlyView.
A multifunctional polymer layer with amide and imidazolium groups simultaneously suppresses dendrite growth and hydrogen evolution in Zn‐ion batteries. By providing Zn2+ binding sites and forming a confined‐water domain that acts as a coordination bridge, it boosts single‐ion conductivity and stability, enabling 4000 stable cycles in Zn‐I2 full cells ...

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Position space equations for generic Feynman graphs

Physics Letters B
We propose an extension of the position space approach to Feynman integrals from the banana family to generic Feynman diagrams. Our approach is based on omitting integration in position space and then writing differential equations for the products of ...

Graph Equivalence Classes for Spectral Projector-Based Graph Fourier Transforms

CoRR, 2017
We define and discuss the utility of two equivalence graph classes over which a spectral projector-based graph Fourier transform is equivalent: isomorphic equivalence classes and Jordan equivalence classes. Isomorphic equivalence classes show that the transform is equivalent up to a permutation on the node labels.

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

Advanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing
