Reversible Stress‐memory Phosphorescent Carbon Nanodots via Supramolecular Confinement Engineering for Aerospace Monitoring

open access: yesAdvanced Science, EarlyView.
A kind of new CNDs‐based materials with reversible mechano‐responsive phosphorescence emission through incorporating CNDs into the supramolecular rigid network is leveraged for aerospace applications, where the CND‐embedded film demonstrated memorable visualization of stress distribution in wings under sudden mechanical events (e.g., micro‐impacts ...

Emerging of Anomalous Higher‐Order Topological Phases in Altermagnet/Topological Insulator Heterostructure by Floquet Engineering

open access: yesAdvanced Science, EarlyView.
We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

Three infinite families of Hamilton-connected convex polytopes and their detour index

open access: yesAIMS Mathematics
A path in a graph encompassing its whole vertex set is called Hamiltonian. Such a path with sharing the same initial and terminal vertices is called a Hamiltonian cycle. A graph comprising a Hamiltonian path (resp.

Orbital Hybridization‐Mediated Decoupling of Electrocatalytic Functions for Paired CO2 Electrosynthesis

open access: yesAdvanced Science, EarlyView.
This study constructs a dual‐scale Ag‐based catalyst on CeO2 nanorods via a facet‐guided strategy. This catalyst can induce a cascaded orbital hybridization effect, which synergistically optimizes oxygen vacancy stability, CO desorption kinetics, and charge transfer efficiency.

Lower Bound on the Number of Hamiltonian Cycles of Generalized Petersen Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
In this paper, we investigate the number of Hamiltonian cycles of a generalized Petersen graph P (N, k) and prove that Ψ(P(N,3))⩾N⋅αN,\Psi ( {P ( {N,3} )} ) \ge N \cdot {\alpha _N}, where Ψ(P(N, 3)) is the number of Hamiltonian cycles of P(N, 3) and αN ...

Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

MIM‐Diode‐Like Rectification in Lateral 1T/1H/1T‐MoS2 Homojunctions via Interfacial Dipole Engineering

open access: yesAdvanced Electronic Materials, EarlyView.
The metallic 1T and semiconducting 1H phases of MoS2 enable phase‐engineered 1T/1H/1T homojunctions that exhibit MIM‐diode‐like rectification without dissimilar electrodes. Asymmetric 1T/1H interfaces induce interface dipoles and a built‐in potential drop across the 1H barrier, creating a trapezoidal tunnel barrier at zero bias and yielding diode‐like ...

Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

open access: yesAdvanced Electronic Materials, EarlyView.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...
