Phase Engineering Enabled Excellent Power Factor and Reduced Thermal Conductivity in ZrCoSb‐Based Half‐Heusler Compounds

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In situ precipitation of Zr6Co16Si7 in ZrCoSb‐based half‐Heusler enables Fermi level optimization and enhanced phonon scattering. Electrical conductivity is significantly improved while the power factor continuously increases, reaching ~3.36 mW m−1 K−2.

Hydroflux Access to Hydroxide‐Free Yttrium Oxovanadate and Arsenite Layers: K6[Y(VO4)3]·2H2O, K6[Y(VO4)3], and Na3[Y(AsO3)2]

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Strongly alkaline hydroflux media commonly yield hydroxide‐rich rare‐earth compounds. In contrast, K6[Y(VO4)3]·2H2O, its anhydrate K6[Y(VO4)3], and Na3[Y(AsO3)2] show that the low activity of water in the medium can favorcondensation into extended hydroxide‐free Y─O─V and Y─O─As networks instead of isolated hydroxo complexes.

Magneto‐Electrochemical Effect on La‐Doped GaFeO3 as a Supercapacitor Electrode for Energy Storage

open access: yesElectron, EarlyView.
The electrochemical performance of La‐doped Gallium Ferrite (La‐doped GaFeO3 ${\text{GaFeO}}_{3}$) synthesizes via a conventional solid‐state reaction method; this has been studied by the application of an external magnetic fields. ABSTRACT The electrochemical performance of La‐doped GaFeO3 ${\text{GaFeO}}_{3}$ synthesizes via a conventional solid ...

Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization

open access: yesEnergy Science &Engineering, EarlyView.
The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Artificial structures for human‐machine interfaces with closed‐loop interaction

open access: yesFlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities

open access: yesLaser &Photonics Reviews, EarlyView.
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

open access: yesLaser &Photonics Reviews, EarlyView.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Side‐DBR Guided Exciton‐Polariton Lasing With Near‐Field Mode Imaging in an InGaN Thin‐Film Ridge Waveguide

open access: yesLaser &Photonics Reviews, EarlyView.
Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route

Electroweak Interaction Model with an Undegenerate Double Symmetry

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
The initial P-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.
