Multilayer all-dielectric metasurfaces expanding color gamut.

Structural color, arising from the interaction between nanostructures and light, has experienced rapid development in recent years. However, high-order Mie resonances in dielectric materials often induce unnecessary sub-peaks, particularly at shorter wavelengths, reducing the vibrancy of colors. To address this, we have developed a multilayer dielectric metasurface based on silicon-rich silicon nitride (SRN), achieving expanded color gamut through precise refractive index matching and suppression of high-order resonances.

Designed wrinkles for optical encryption and flexible integrated circuit carrier board.

Patterns on polymers usually have different mechanical properties as those of the substrates, causing deformation or distortion and even detachment of the patterns from the polymer substrates. Herein, we present a wrinkling strategy, which utilizes photolithography to define the area of stress distribution by light-induced physical crosslinking of polymers and controls diffusion of residual solvent to redistribute the stress and then offers the same material for patterns as substrate by thermal polymerization, providing uniform wrinkles without worrying about force relaxation. The strategy allows the recording and hiding of up to eight switchable images in one place that can be read by the naked eye without crosstalk, applying the wrinkled polymer for optical anti-counterfeiting.

Forest Type and Climate Outweigh Soil Bank in Shaping Dynamic Changes in Macrofungal Diversity in the Ancient Tree Park of Northeast China.

The community structure of macrofungi is influenced by multiple complex factors, including climate, soil, vegetation, and human activities, making it challenging to discern their individual contributions. To investigate the dynamic changes in macrofungal diversity in an Ancient Tree Park located in Northeast China and explore the factors influencing this change, we collected 1007 macrofungi specimens from different habitats within the park and identified 210 distinct fungal species using morphological characteristics and ITS sequencing. The species were classified into 2 phyla, 6 classes, 18 orders, 55 families, and 94 genera.

Metasurface-enabled polarization-independent LCoS spatial light modulator for 4K resolution and beyond.

With the distinct advantages of high resolution, small pixel size, and multi-level pure phase modulation, liquid crystal on silicon (LCoS) devices afford precise and reconfigurable spatial light modulation that enables versatile applications ranging from micro-displays to optical communications. However, LCoS devices suffer from a long-standing problem of polarization-dependent response in that they only perform phase modulation on one linear polarization of light, and polarization-independent phase modulation-essential for most applications-have had to use complicated polarization-diversity optics. We propose and demonstrate, for the first time, an LCoS device that directly achieves high-performance polarization-independent phase modulation at telecommunication wavelengths with 4K resolution and beyond by embedding a polarization-rotating metasurface between the LCoS backplane and the liquid crystal phase-modulating layer.

A Multilocus Phylogeny Places (syn. ) in the Helotiales, Leotiomycetes.

The soilborne fungus causes Cephalosporium stripe, a vascular wilt disease of wheat and other grasses in the United States and other wheat-producing countries where winter wheat is subjected to snow cover and frozen soil. No sexual stage is known for , and consequently, its phylogenetic position relative to other fungi has been difficult to establish. The purpose of this study was to conduct a multilocus sequence analysis to determine the phylogenetic position of .

Assessment of Contents and Health Impacts of Four Metals in Chongming Asparagus-Geographical and Seasonal Aspects.

In this paper, the contents of four typical metals (Pb, Cd, Hg, and As) in asparagus, water, and soil from Chongming Island were quantitatively determined by inductively coupled plasma mass spectrometry (ICP-MS). The contents of these metals in asparagus showed a common rule of Pb > As > Cd > Hg in different harvest seasons and regions. Significant seasonal differences were found in the contents by difference analysis, but no obvious regional differences were observed.

Botryane Sesquiterpenoids, Cyclopentadepsipeptides, Xanthones, and Trichothecenes from Trichoderma oligosporum.

Five new botryane sesquiterpenes (1: -5: ), one new cyclopentadepsipeptide (9: ), and two new xanthones (11:  - 12: ), together with 11 known compounds, were isolated from . The structures of the new compounds were identified by comprehensive spectroscopic methods including nuclear magnetic resonance and mass spectrometry. The cytotoxicity of 1: -19: was evaluated against K562, A549, and ASPC cell lines.
