Article Abstract
The realization of linearly polarized emissions in organic light-emitting diodes has emerged as a significant research focus, driven by its potential for advanced display and optical applications. However, conventional approaches for generating polarized light often involve complex out-coupling structures or mechanical treatments that may reduce device efficiency and pose difficulties in large-area fabrication. In this study, we introduce a strategy utilizing a metasurface mirror as the bottom reflector to enable high-efficiency polarized light emission. This metasurface, featuring subwavelength groove arrays, strategically enhances the emission of targeted polarizations while effectively suppressing the emission of orthogonal polarizations via precise reflection phase control. Our results demonstrate a significant increase of 36.7% in the emission efficiency for a specific polarization direction, along with improved color stability at wide viewing angles. This innovation represents a significant advancement in the development of high-performance, linearly polarized light-emitting diodes, offering a scalable and efficient solution for next-generation optoelectronic applications.

This study develops an integrated X-ray absorption spectroscopy (XAS) photoemission electron microscopy (PEEM) platform on beamline BL09U at the Shanghai Synchrotron Radiation Facility (SSRF), enabling nanoscale characterization of complex materials through energy-resolved imaging and local-area XAS. By using the wide range of energy tunability, full access to different polarizations and PEEM's surface sensitivity, we have established a gap-monochromator control system under the EPICS framework to synchronize the elliptically polarized undulator (EPU) gap and monochromator energy dynamically, optimizing photon flux stability for absorption fine structure analysis. Combining X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) with PEEM and local-area XAS, this platform achieves concurrent mapping of electronic structures and magnetic domains in ferromagnetic nano-patterns, as demonstrated through our studies of NiFe Permalloy using this system.

Background: A new technology, the POLAR cryoballoon system, was designed to enhance maneuvering and stabilizing catheter positions with a softer balloon and more deflectable sheath. These novel characteristics may help achieve successful pulmonary vein (PV) isolation in difficult cases when conventional balloons were used.
Objective: This study aimed to investigate the differences in the lesion profiles, touch-up radiofrequency ablation (RFA) rate, and anatomical predictors of acute PV isolation between the POLAR and Arctic Front Advance Pro (AFA-Pro).

Helical structures are ubiquitous in nature and exhibit fascinating properties. They are inherently chiral, and many rely on hydrogen bonds to stabilize their conformation. Homopolypeptides of the glutamate type form α-helical secondary structures and are considered rigid-rod polymers.

Hypothesis: The surface free energy (γ) and solubility (δ) parameters are two important characteristic parameters describing physicochemical properties of substances, but knowledge about the characteristic parameters (γ and δ) of surfactants is still lacking. Possible relationships of the characteristic parameters of surfactants with their head group types and alkyl chain lengths as well as with the surface tension (σ) of their aqueous solutions are worth exploring.
Methods: Solid surfactants including 10 anionic and 14 cationic ones were chosen.

Topological photonics explores photonic systems that exhibit robustness against defects and disorder, enabled by protection from underlying topological phases. These phases are typically realized in linear optical systems and characterized by their intrinsic photonic band structures. Here we experimentally study Floquet Chern insulators in periodically driven nonlinear photonic crystals, where the topological phase is controlled by the polarization and the frequency of the driving field.
