Eco-friendly biodegradable PBAT/PLA mulch films are attracting increasing interest in sustainable agricultural production. However, currently, little is known about the service life for films. Herein, subjected to indoor UV-accelerated degradation (UAD) experiments and field cultivation environment (CED) systematically investigate relationship between UAD CED processes. Results demonstrate that 10 days of treatment corresponds around 120 aging under outdoor conditions. Using eight evaluation...
Most Graph Neural Networks (GNNs) predict the labels of unseen graphs by learning correlation between input and labels. However, presenting a graph classification investigation on training with severe bias, surprisingly, we discover that GNNs always tend to explore spurious correlations make decision, even if causal exists. This implies existing trained such biased datasets will suffer from poor generalization capability. By analyzing this problem in view, find disentangling decorrelating...
Using conventional melt-quenching and subsequent thermal treatment, Er3+ doped CaF2 transparent glass ceramic (GC) was prepared. X-ray diffraction high-resolution transmission electron microscopy confirmed the formation microstructure of nanocrystals in glass. An energy-dispersive spectrometer used to investigate distribution ions It found that prefer concentrate rather than a matrix, amount plays key role matrix with as nucleating agent. intense 2.7 μm emission due Er3+: I11/24→I13/24...
Absolute up-conversion quantum efficiency (UCQE) up to 4% is achieved in Li<sup>+</sup>-doped β-NaYF<sub>4</sub>:Yb<sup>3+</sup>,Er<sup>3+</sup> micro-cylinders developed <italic>via</italic> Li<sup>+</sup>/Na<sup>+</sup> ion-exchange.
Genomic structural variants (SVs) are a major source of genetic diversity in humans. Although numerous studies explore SV across global populations and their potential impacts, validation using model systems needed to confirm the reported genotype-phenotype associations. Here, through long-read sequencing 945 Han Chinese genomes, we identify 111,288 SVs, including 24.56% unreported variants, many predicted be functionally important. Our analysis unveils multifaceted origins these SVs within...
Selective micron-regional (diameter: ∼30 μm) control of PbS QDs in a waveguide directly written with fs laser glass is confirmed confocal Raman spectra. Adjustable photoluminescence band can be realized from ∼800 nm up to ∼1100 nm.
We develop an efficient green upconversion (UC) β-NaYF4:20%Yb3+,2%Er3+ microcrystal with well controlled morphology and size by hydrothermal method using two different chelating agents of CIT EDTA-2Na via a simple ion-exchange reaction. Importantly, the UC emission efficiency newly developed microcrystals is almost as strong that commercial counterpart solid-state method. A proof-of-concept waveguide demonstrated to extend their applications in modern micro-optoelectronics. The local...

Abstract We report efficient dual‐mode up‐conversion (UC) and down‐shifting (DS) emission in a single Yb 3+ /Er ‐co‐doped β‐NaYF 4 microcrystals with controlled morphology size via simple Na + ion‐exchange modification (IEM) method. IEM well preserves the crystal structure monodispersed of hydrothermal‐synthesized β‐Na YF . Meanwhile, gives rise to significant enhancement UC intensity up 3800 times strongly enhanced DS Er by several :Yb ,Er microcrystals. also prolongs lifetimes visible...
Borosilicate glasses doped with PbO , ZnS or PbS were fabricated to investigate the visible emissions (one located at 370 nm and another 550 nm) observed in codoped glass. Several series of glassy systems designed mechanism above emissions. The absorption, photoluminescence ( PL ), excitation PLE ) spectra, lifetime measurements used characterize all nanosecond level lifetimes for samples' ascribed emission glass defects. Measured quantum dots QD s) an near‐infrared region which was about 8...
The burgeoning field of rare-earth (RE)-based van der Waals (vdW) layered magnets is driven by their potential in novel magnetism and spintronics applications. These materials exhibit exceptional spin-lattice coupling air stability, attributed to the strong spin-orbit substantial magnetic moments from 4f electrons. This study investigates structural properties dysprosium-based oxyhalide ternary compounds, DyOX (X=F,Br), which are prime candidates for multiphase transitions tunable anisotropy...
