The objective of the study is to optimize the optical fiber structure for mode-division multiplexing systems using nanostructurization. The nanostructuring technique allows to fabricate fibers with arbitrarily designed (free-form) refractive index distribution based on two glasses. Three optimization schemes have been proposed. The nanostructuring method allows for designing fibers with optical properties similar and even better parameters impossible to produce by other methods. In this proposal, we examined four linearly polarized (LP) few-mode fibers. We report a high effective refractive index difference between modes while maintaining other important parameters for the weakly coupled approach.

Relaxor ferroelectric film capacitors exhibit high power density with ultra-fast charge and discharge rates, making them highly advantageous for consumer electronics and advanced pulse power supplies. The Aurivillius-phase bismuth layered ferroelectric films can effectively achieve a high breakdown electric field due to their unique insulating layer ((BiO) layer)). However, designing and fabricating Aurivillius-phase bismuth layer relaxor ferroelectric films with optimal energy storage characteristics is challenging due to their inherently stable ferroelectric properties.

Collective optical properties can emerge from an ordered ensemble of emitters due to interactions between the individual units. Superlattices of halide perovskite nanocrystals exhibit collective light emission, influenced by dipole-dipole interactions between simultaneously excited nanocrystals. This coupling changes both the emission energy and rate compared to the emission of uncoupled nanocrystals.

Two new dimorphic spin-1/2 quantum magnets, α- and β-CuO(VO)Cl, were synthesized via a chemical vapor transport method that emulates mineral formation in volcanic fumaroles. α-CuO(VO)Cl () is a pure vanadate analogue of the coparsite mineral characterized by [OCu] 1 single rods, whereas β-CuO(VO)Cl () adopts a new structure type with the [OCu] 2 layered topology. The thermal expansions of both and studied by high-temperature single-crystal X-ray diffraction are reported.

Advancements in pulsed electronic power systems depend significantly on high-performance dielectric energy storage ceramics. Lead-free NaNbO-based energy-storage ceramics are important materials for next-generation pulsed power capacitors owing to their large polarization and bandgaps. However, the high energy loss caused by the antiferroelectric-ferroelectric phase transition leads to low recoverable energy storage density and efficiency, which hinders its practical application.
