Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Cooperative resonance linewidth narrowing in a planar metamaterial
New Journal of Physics, 2012 We theoretically analyse the experimental observations of a spectral line collapse in a metamaterial array of asymmetric split ring resonators (Fedotov et al 2010 Phys. Rev. Lett. 104 223901).

Gyrotropy and permittivity sensing driven by toroidal response
New Journal of Physics, 2023 Using a quasi-static model of a toroidal metamaterial we demonstrate analytically that simultaneous excitation of the magnetic and toroidal dipoles in an array of subwavelength toroidal solenoids results in gyrotropic behaviour resembling conventional ...

Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Advanced Materials, EarlyView.ABSTRACT Microneedle arrays (MNAs) is a rapidly emerging technology with broad biomedical applications in drug delivery and biosensing. With sub‐millimeter dimensions and periodicity, MNAs possess geometries nearly ideal for biomedical devices operating within the terahertz (THz) spectral window.

From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir‐Blodgett Films
Advanced Optical Materials, EarlyView.The supramolecular organization of amphiphilic boron‐dipyrromethene (BODIPY) dyes in Langmuir–Blodgett monolayers is shown to govern their optical anisotropy. By correlating nanoscale imaging and angle‐resolved spectroscopy, we reveal symmetry‐driven control of transition dipole orientation, enabling either in‐plane or out‐of‐plane optical responses ...
