The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

Archaeometry, EarlyView.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

Quasi-bound states in the continuum in finite waveguide grating couplers

Nanophotonics
Finite-size effects occurring for quasi-bound states in the continuum (qBICs) formed in symmetric and asymmetric all-dielectric waveguide grating couplers are investigated using numerical simulations for different configuration parameters.

Humins‐Derived Hard Carbon as a Low‐Cost Material for Sodium‐Ion Battery Anodes

Battery Energy, Volume 5, Issue 5, September 2026.
Humins are oxygen‐rich polymeric residues with high carbon content and inherent porosity. In this study, humins‐derived hard carbon is evaluated as an anode material for sodium‐ion batteries, demonstrating promising reversible specific sodiation capacity, 270 mA h g − 1 $270\,{\text{mA h g}}^{-1}$ at 0.1C, with stable cycling up to 500 cycles and ...

Bionic Tactile Skins for Robotics: Fundamentals, Advances, and Future Prospects

SmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Robotic bionic tactile skins (RBTSs), as crucial components of next‐generation robotic systems, have attracted significant attention in recent years. By enabling robots to achieve human‐like tactile perception and interact effectively with their surroundings, RBTSs play an essential role in enhancing robotic intelligence.

Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

X-Ray Spectrometry, Volume 55, Issue 5, Page 704-711, September/October 2026.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.

Quantum Plasmonic Dynamics Modeled via a Modified Langevin Noise Formalism: Numerical Studies of Single‐Photon Emission and Two‐Photon Interference

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
Based on the modified Langevin noise formalism and BA‐MA theory, optimized computational formulations are demonstrated for quantum plasmonic simulations without explicit BA–MA mode construction. Plasmonic Hong‐Ou‐Mandel interference, g2, atomic population, and single‐photon probability amplitudes are efficiently analyzed, revealing directional single ...

Tunable Unidirectional Guided Resonances via Multi‐Singularity Interactions in Momentum Space

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
C points can intrinsically coexist around symmetry‐protected BICs without symmetry reduction. Symmetry breaking splits SP‐BICs into new C points that interact with intrinsic ones, forming perfect UGRs at distinct k points with tunable topological charges.
