Kirigami‐Inspired Deployable Microneedle Robot With Enhanced Conformability for Targeted Oral Drug Delivery

Small, EarlyView.
We have engineered a kirigami‐inspired deployable microneedle robot (KiriBot) capable of remotely controlled attachment to target tissues for sustained drug release. KiriBot incorporates a flexible structure that enhances conformability, improves adherence to irregular tissues, and facilitates microneedle insertion.

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials

Small, EarlyView.
Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Accessing Both Electrochemical SEIRA and SERS With Highly Sensitive Metamaterials for Enhanced Molecular Identification

Small, EarlyView.
Surface‐enhanced infrared absorption (SEIRA) and Raman scattering (SERS) are complementary, highly sensitive molecular detection methods. A reusable metamaterial substrate capable of combined SEIRA and SERS is used here for real‐time sensing, tracking interfacial dynamics in an electrochemical reaction and detecting symmetry‐breaking behavior at the ...

Titanium Oxide Thin Films With Metal Nanodisks as Plasmonic Metamaterial Photocatalyst Sheets for IPA‐Assisted CO2 Reduction

Small, EarlyView.
Plasmonic metal nanodisks (Ag, Au, Pt, Pd) combined with TiO2 thin films were fabricated into periodic metamaterial photocatalyst sheets by using standard semiconductor methods. Under visible light, Pt/TiO2 and Pd/TiO2 achieved hydrogen and methane production from CO2 and water using isopropyl alcohol, demonstrating promising solar‐fuel production ...

Quantum Thermodynamic Transformation Optics: A Unified Framework for Energy and Entropy With Application to the Casimir Force in Dissipative Metamaterials

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
Geometry in transformation optics can be extended to control quantum–thermal fluctuations, enabling redistribution of energy, entropy, and Casimir pressure in dissipative metamaterials. ABSTRACT A novel concept, quantum thermodynamic transformation optics (QTTO), is introduced as a theoretical framework integrating transformation optics with ...

Multiscale PA6 Composites Reinforced With Recycled Carbon Fibers and Graphene: Synergistic Effects on Mechanical and Electromagnetic Behavior

Polymer Composites, Volume 47, Issue 21, Page 19700-19717, 10 November 2026.
Synergistic effects of recycled carbon fibers and GNP on the mechanical and electromagnetic performance of multiscale PA6 composites. ABSTRACT The mechanical recycling of carbon fiber‐reinforced thermoplastics (CFRTs) generally degrades the mechanical properties of the resulting composites, primarily due to fiber length reduction. To partially overcome

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, Volume 38, Issue 61, 2 November 2026.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest
