    Termination dependent electronic structure of PrAlSi

    PrAlSi family is commonly found to crystallize in a tetragonal structure with the nonsymmorphic space group of I41/md (No. 109)28,32. As illustrated in Fig. 1a, Pr, Al and Si atoms all form…

  • New Tunneling Technique Reveals Hidden Properties of High-Temperature Superconductors

    New Tunneling Technique Reveals Hidden Properties of High-Temperature Superconductors

    High-pressure electron tunneling spectroscopy reveals the presence of a superconducting gap in H₃S and D₃S. Superconductors are materials that can conduct electrical current without any resistance, making them crucial for applications such as…

  • Strain-enhanced two-photon absorption in twisted bilayer graphene

    Strain-enhanced two-photon absorption in twisted bilayer graphene

    We begin by examining AA-stacked bilayer graphene and introduce a deformation through two distinct modifications: (1) a relative twist between the layers by − θ/2 and + θ/2 respectively, and (2) application of uniaxial strains of equal…

    Metamaterial conical beam antenna with dual band filtering response

    Characteristics of the MTM

    As we know, the hollow square waveguide with the transverse sizes of 14.5 mm × 14.5 mm, as shown in Fig. 1a, has a cut-off frequency of ~ 10.34 GHz according to the waveguide theory34. Commonly, when the…

  • Observation of symmetry-forbidden rectification in an inversion-symmetric Weyl metal

    Observation of symmetry-forbidden rectification in an inversion-symmetric Weyl metal

    In the previous study, the IV characteristic curves for E // B were nonlinear, while they were linear in other E and B configurations, and the nonlinearity was more pronounced with increasing B3,4. The nonlinear conductivity Δσ evaluated from…

    Flow physics of nutrient transport drives functional design of ciliates

    Energetic feasibility of flow-driven nutrient transport in microbal cells

    Bacterial cells, which are commonly preyed upon by ciliates, are often 1000-fold smaller in volume (Fig. 1A). Bacteria rely on diffusion for both intracellular transport2,

  • Experimental determination of TNT equivalence values for binary energetic materials

    Experimental determination of TNT equivalence values for binary energetic materials

    Three test series were conducted to establish TNT equivalence values for Helix, Texpak, Kinepak, Rimfire, and Tannerite: (1) plate dent test, (2) reaction velocity, and (3) air blast. Each will be discussed individually, followed by a comparative…
