By decorating graphene with nanoscale metals to screen long-range Coulomb interactions and suppress velocity renormalization, researchers observed a hard spectral gap at the Dirac point with signatures of a Berezinskii--Kosterlitz--Thouless transition, providing the first experimental evidence for spontaneous excitonic mass generation in graphene.
This paper presents a thermally reconfigurable V–VO₂ hyperbolic metamaterial absorber featuring a Rubik's-Cube-inspired symmetric design that achieves stable dual-band broadband absorption across 16–40 GHz and enables 2-bit spectral coding through independent thermal switching of K- and Ka-band units.
This study demonstrates that simultaneous Ni–Zn substitution and controlled graphite addition in Ba₂Co₂₋ₓNiₓ/₂Znₓ/₂Fe₁₂O₂₂ hexaferrites effectively tune magnetic resonance and impedance matching, significantly enhancing microwave absorption performance with a broad effective bandwidth of 4.0 GHz at a reduced thickness of 3.0 mm.
This paper presents a closed-form Laplace-domain solution for thermal-wave propagation in layered Maxwell–Cattaneo–Vernotte conductors, demonstrating that while thermal-wave impedance matching can eliminate front reflections at interfaces, high contact resistance and wave damping significantly limit this effect, often causing the Fourier model to predict reflections of the opposite sign.
This study demonstrates that a stable nanoscale architecture in bulk Cu–Ta alloys, characterized by interfaces spaced approximately 15 nm apart, simultaneously constrains both electron and dislocation transport, thereby unifying the control of thermal conductivity and plastic deformation in metals.
This study quantifies the impact of plasma-induced sidewall defects on blue InGaN/GaN micro-LED efficiency by combining spatially resolved micro-cathodoluminescence and electrical characterization to reveal a ~1 µm damaged region with significantly elevated non-radiative recombination, while demonstrating that KOH wet etching and SiO₂ passivation effectively mitigate the resulting size-dependent efficiency droop.
This paper analyzes the asymptotic Mode-I crack-tip fields in an incompressible finite-strain viscoelastic solid, revealing that while the vertical opening retains a square-root dependence governed by the equilibrium modulus, the horizontal field exhibits a distinct order-selection problem with non-universal angular behavior that relaxes at a different rate than the opening amplitude.
This paper presents a multi-wavelength digital holography technique utilizing spatially diverse speckle illumination to effectively suppress parasitic reflections and reconstruct macroscopic topography with high precision over extended unambiguous height ranges without mechanical scanning.
This study utilizes unsteady computational fluid dynamics to demonstrate that distinct early flight movement-strategy clusters in ski jumping correspond to unique aerodynamic profiles, ranging from drag reduction to lift-oriented and balanced force development.
This study demonstrates that Mn²⁺ substitution in nanocrystalline Mg₀.₂MnₓCo₀.₈₋ₓFe₂O₄ ferrites, synthesized via sol–gel auto-combustion, systematically tunes structural, magnetic, and electrical properties by refining crystallite size and altering cation distribution, thereby enhancing multifunctional characteristics suitable for advanced magnetic and high-frequency applications.
