Advanced 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 ...

Advanced 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 ...

Amorphous BiSnxOy for Efficient CO2 Electroreduction to Formate via In Situ Doping
Advanced Science, EarlyView.The amorphous BiSnxOy catalyst is electroreduced to Sn‐doped Bi during the electrochemical process. The Sn‐modulated Bi exhibits a favorable intermediate adsorption potential, leading to optimal catalytic efficiency. Remarkably, this catalyst demonstrates exceptional performance, achieving a Faradaic efficiency (FEformate) of 95.6% at 800 mA cm−2 in a ...

An Integrated Integrable Hierarchy Arising from a Broadened Ablowitz–Kaup–Newell–Segur Scenario
AxiomsThis study introduces a 4×4 matrix eigenvalue problem and develops an integrable hierarchy with a bi-Hamiltonian structure. Integrability is ensured by the zero-curvature condition, while the Hamiltonian structure is supported by the trace identity ...

Realization of a Bilayer Elastic Topological Insulator
Advanced Science, EarlyView.Bilayer elastic wave topological insulators are experimentally realized, introducing the layer degree of freedom to access four topological phases. This enables diverse domain walls and transmission behaviors, including interlayer conversion and beam splitting.

Advanced 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.

Advanced Energy Materials, EarlyView.In this work, we developed a phase‐stability predictor by combining machine learning and ab initio thermodynamics approaches, and identified the key factors determining the favorable phase for a given composition. Specifically, a lower TM ionic potential, higher Na content, and higher mixing entropy favor the O3 phase.

Oscillation of self-adjoint linear matrix Hamiltonian systems
Journal of Mathematical Analysis and Applications, 2004 The author establishes oscillation criteria for the Hamiltonian system \[ X'(x)=A(x)X(x)+B(x)Y(x), \quad Y'(x)=C(x)X(x)-A^*(x)Y(x). \] The obtained criteria are of the form \[ \limsup_{x\to\infty}q\left(\int_r^x \left[\Phi(x,s,r) T(s)+J_0(x,s,r)\right]ds\right)>q(0), \] where \(q\) is a monotone functional.
