Summary: It is important to enhance the light extraction efficiency for micro-LEDs due to their larger surface-to-volume ratio. This study simulated the trapezoidal chip structure, surface grating, and surface coarsening to investigate their contributions. The results showed that all three methods can increase the light extraction, with the surface grating method achieving the highest efficiency. These findings provide valuable guidance for future high-efficiency micro-LED design.

Summary: The coordination-driven self-assembly of metallacages has attracted significant interest due to their 3D layout and cavity-cored nature, making them particularly attractive for studying luminophores and inducing novel photophysical characters. By incorporating ligands displaying aggregation-induced emission (AIE) into metallacages, favorable photophysical properties have been achieved, leading to the development of supramolecular luminophores for diverse applications in fields such as sensing, biomedicine and catalysis.

Summary: A moth-eye nanopatterned hole-transporting layer (ME-HTL) is proposed to enhance the device efficiency of organic light-emitting diodes (OLED), with a current efficiency of 78.9 cd/A and an enhancement factor of 40%. This approach takes advantage of manufacturing compatibility and could be a promising strategy to reduce the production cost of OLEDs.

Summary: Total internal reflection is important for applications like fiber optics, but not ideal for LEDs. Recent advances in material science have improved light extraction efficiency, but fabrication of geometrical features for extraction remains a challenge. A new disordered metasurface design allows for simple fabrication and improved LED efficiency.

Summary: This paper proposes a progressive self-calibration network model (PSCNet) for recovering high-quality low-light-enhanced images. The PSCNet utilizes attention mechanism to better extract shallow features in low-light images and combines the transformer and encoder-decoder jump connection structures with semantic information for rich deep feature learning. The self-calibration module adaptively cascades the features decoded by the decoder and input them into the residual attention module for quick and accurate enhancement.

Summary: In this study, three self-assembling materials were used as hole-injecting layers in organic light-emitting diodes (OLEDs), and their effects on the device performance were investigated. The results show that the type and tilting angle of the aromatic ring in the materials have an impact on the work function, hole injection, and device efficiency. Different materials exhibit different performance in different devices.

Summary: This study systematically investigated the effects of nematic liquid crystal on light extraction of bulk perovskite and fabricated improved performance PeLEDs. Results showed that the presence of nematic liquid crystals reduces the refractive index contrast between the perovskite layer and charge transportation layers, leading to enhanced light extraction efficiency and luminance performance.

Summary: This study reports an ultralow loss isotropic metamaterial for visible light and investigates its inverse Doppler effect. By using ball-thorn-shaped metaclusters with a super-thin silver layer, it has been possible to measure the negative refractive index and the inverse Doppler effect of visible light. The discrete super-thin silver layer produced by the photoreduction method significantly reduces energy losses, opening up possibilities for the fabrication of arbitrary-shaped, low-loss isotropic three-dimensional metamaterial devices.

Summary: In this work, the authors propose a novel Adaptive Frequency Decomposition Network (AFDNet) for enhancing low-light images. They utilize an Adaptive Frequency Decomposition (AFD) module to extract low and high frequency information and improve contrast, noise, and detail. Extensive experiments show that AFDNet outperforms existing state-of-the-art methods both quantitatively and visually.

Summary: This study reports a new anthraquinone-derived acyclic ionophore that forms a stable binuclear lithium adduct with high binding affinity and selectivity over sodium and potassium. This adduct efficiently extracts and transports lithium ions from dilute solutions with a concentration as low as 10 ppm and from seawater. The findings offer a promising approach for lithium sequestration from natural resources.

Summary: In this study, a scalable method for the fabrication of self-assembled GeSn vertical nanowires was proposed. Self-assembled Sn nanodots were formed on the surface of thermally treated GeSn materials, enhancing the spontaneous emission. Using the Sn nanodots as templates, vertical GeSn nanowires were obtained through Cl-based ICP dry etching technique. A prototype GeSn nanowire photodetector with rapid switching ability exhibited excellent optoelectronic performance. The results suggest that this method holds promise for low-cost and scalable fabrication of GeSn nanowires for nanophotonic devices.

Summary: In this paper, we propose an effective method for low-light image enhancement based on the JND and OCTM models. The method decomposes the original images into base and detail images using a guided filter, and adjusts the brightness of the base images while enhancing the details of the detail images. Additionally, a new method is proposed to generate a sequence of artificial images to improve brightness adjustment with better image detail preservation compared to other algorithms. Experimental results demonstrate the superiority of the proposed method in low-light image enhancement.
