Lattice of $E$-closed Classes of Multifunctions of Rank 2
Известия Иркутского государственного университета: Серия "Математика"Multifunctions are discrete functions defined on a finite set and returning as their values all subsets of the considered set. The paper considers the classification of multifunctions defined on a two-element set with respect to the E-closure operator ...

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Advanced Materials, EarlyView.Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

A linear test for global nonlinear controllability
Comptes Rendus. MathématiqueIt is known that if a nonlinear control affine system without drift is bracket generating, then its associated sub-Laplacian is invertible under some conditions on the domain. In this note, we investigate the converse.

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

High‐Precision 3D Doping of Fused Silica Glass Derived from Nanocomposites
Advanced Materials, EarlyView.The local integration of dopants enables the selective modification of color, luminescence or refractive index within a three‐dimensionally shaped glass with micron resolution. Following the fabrication of porous glass preforms and infusion with a dopant mixture, the dopant is immobilized by lithographic techniques and subsequently debinded and ...

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation
Advanced Materials, EarlyView.In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.
