A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Seismic Fragility of Fixed and Flexible Base RC Bridge under Near-Fault Directivity Effects

Journal of the Civil Engineering Forum
Reinforced Concrete bridges are widely used in highway infrastructure due to their cost-effectiveness and structural redundancy. However, they are highly vulnerable to seismic hazards, particularly in near-fault regions where ground motions exhibit ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

A simplified method for determining the equivalent peak ground acceleration of near-fault pulse-like ground motions

Geomatics, Natural Hazards & Risk
Near-fault ground motions (NFGMs) differ significantly from far-field ground motions (FFGMs), as NFGMs exhibit pronounced pulse effects and directionality.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Pseudo-input signal generation for smart structural control and fast seismic response analysis

Frontiers in Built Environment
A pseudo-input signal generation method that realizes the pre-specified structural responses is proposed for fast and accurate analysis. The proposed generation method is based on the singular value decomposition and unit impulse responses in a discrete ...

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Gate‐Tunable Floquet Weyl Photon Emission from Topological Dirac Semimetal Cd3As2

Advanced Materials, EarlyView.
We report experimental demonstration of Floquet band engineering in a 3D Dirac semimetal. Circularly polarized light breaks the time reversal symmetry and transforms Cd3As2 into a Floquet–Weyl phase, splitting Dirac nodes into chirality‐opposite Weyl nodes with nonzero Berry curvature.
