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

Characterization of Sub-Resonant Dielectric Spheres by Millimeter-Wave Scattering Measurements
SensorsWhen measuring the size or relative permittivity of a dielectric particle, usually one of the parameters needs to be known for determining the other one. Scattering measurement methods offer an alternative that allows for extracting both the size and the

Directional Flow of Confined Polaritons in CrSBr
Advanced Materials, EarlyView.CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Relative permittivity measurements of aqueous co-solvent systems including tetrahydrofuran
, 2017 Permittivity values of a co-solvent system decrease with increasing temperature and decrease as mole fraction of water decreases. Fit to a cubic polynomial, the coefficients can be used to determine relative permittivity of the co-solvent system knowing ...

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.

Relative Permittivity Measurement of 3D-textile
The paper deals with the relative permittivity determination of the 3D-textile by a transmission line method (TLM). Measuring points are shifted to avoid inaccuracies caused by transitions between a coaxial cable and a microstrip line.

Measuring the relative permittivity of polyetherimide/(Ba0.8Sr0.2)(Ti0.9Zr0.1)O3
, 2012 [[abstract]]The relative permittivity of polyetherimide-Ba0.8Sr0.2Ti0.9Zr0.1O3 PEI-BSTZ composites is measured from 10 kHz to 1 MHz using plate method. As the content of BSTZ filler is less than 18 vol %, the experimental values are fitted to the values ...
