Strong coupling between RF photons and plasmons of electrons on liquid helium

Plasmons, arising from the collective motion of electrons, can interact strongly with electromagnetic fields or photons; this capability has been exploited across a broad range of applications, from chemical reactivity to biosensing. Recently, there has been growing interest in p...

Mechanisms of Stability of the Metaphase Spindle and Associated Proteins Regulating Microtubule Flux

Abstract How the metaphase spindle in higher eukaryotes maintains stability in the presence of poleward microtubule (MT) flux is a confusing issue. Here, we present a model for the spindle by incorporating augmin-mediated MT connections and MT crosslinking by NuMA proteins. On th...

High‐Performance Stretchable Field‐Effect Transistors Based on Intrinsically Flexible n‐Type Partially Conjugated Polymers Synthesized via Aldol Polycondensation

ABSTRACT Two intrinsically flexible conjugated polymers, PBT‐90 and PFBT‐90 , were designed and synthesized via aldol polycondensation. Both polymers incorporate a novel double‐flexible‐node unit, 5,5'‐bis(1,1,2,2‐tetrafluoro‐2‐(thiophen‐2‐yl)ethyl)‐2,2'‐bithiophene, which can re...

Coherent terahertz magnon–phonon three-wave mixing in a layered antiferromagnet

The coherent nonlinear dynamics between collective excitations, such as magnons and phonons, drive emergent phenomena in quantum materials, yet their direct observation remains limited. Here, using double-terahertz-pump optical-probe spectroscopy, we report the direct observation...

Noncollinear kagome magnet driven by giant antisymmetric exchange

Kagome lattices host exotic phenomena such as quantum spin liquids, topological Weyl nodes, and flat bands. The kagome ferromagnet Co3Sn2S2 has been a focus of debate due to conflicting reports on its magnetic character. Here, using weakly perturbative probes—primarily neutron sc...

In situ precipitation of nanoscale α-Fe enables high-performance Nd2Fe14B/α-Fe nanocomposite ribbons

Nanocomposite magnets combining hard Nd2Fe14B and soft α-Fe phases are promising for surpassing the energy product limit of single-phase permanent magnets, but conventional routes using external Fe powders suffer from poor interfacial compatibility and uncontrolled soft-phase coa...

Anchored Oxygen‐Release‐Suppression Phase Stabilizing High‐Voltage Ni‐Rich Cathode Materials

ABSTRACT The Ni‐rich LiNi x Co y Mn 1−x−y O 2 (x ≥ 0.9) cathode materials (NCMs) have been considered promising for next‐generation Li‐ion batteries owing to their high‐energy density. However, their practical application is hindered by gas evolution and rapid capacity degradatio...

Superconducting Hydride Mg2RhH6 Experimentally Achieved at Lower Pressure

Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressure...

Gate-imprinted memory and light-induced erasure of superconductivity at KTaO3-based interfaces

Realizing non-volatile control of superconductivity is a key step toward integrating memory and quantum functionality in future information technologies. KTaO₃-based heterostructures uniquely host interfacial two-dimensional superconductivity and quantum paraelectric lattice back...

Beyond the Markovian limit: Exact solutions for active motion in a power-law viscoelastic bath

Active particles from bacteria to synthetic microswimmers often navigate viscoelastic media with complex relaxation dynamics. The classical active Brownian model that assumes instantaneous friction is clearly not applicable to describe such motility, while the non-Markovian proce...

MXene-Induced Adsorption of Transition Metals Stabilizes Lithium-Rich Manganese Cathodes against Voltage and Capacity Decay

Abstract Lithium-rich manganese-based materials (LRMO) have emerged as ideal cathode materials for high-energy-density lithium-ion batteries due to their high capacity (>250 mAh/g) and low cost. However, the continuous migration and dissolution of transition metal ions (TM...
