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

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.

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.

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.

Microwave processing and permittivity measurement of thermoplastic composites at elevated temperature [PDF]
, 1999 [Abstract]: The material properties of greatest importance in microwave processing of a dielectric are the complex relative permittivity ε = ε′- jε″, and the loss tangent, tan δ = ε″/ ε′.
