by KeAi Communications Co., Ltd. Schematic diagram of photocatalytic water decontamination mechanism. Credit: Shijie, Li et al. A challenge in promoting the industrial application of photocatalysis technology for environment remediation lies in the design of high-performance photocatalysts. These photocatalysts should be endowed with efficient photo-carrier separation and intense redox potentials to boost photocatalytic pollutant removal. … Read more
Dielectric metasurfaces represent one of the cutting-edge research and application directions in the current optical field. They not only possess the advantage of low loss but also enable the realization of device thicknesses at subwavelength scales. Credit: Advanced Devices & Instrumentation Dielectric metasurfaces represent one of the cutting-edge research and application directions in optics. They … Read more
The proposed ultra-simplified diffraction-based spectrometer. Credit: Light: Science & Applications (2024). DOI: 10.1038/s41377-023-01355-4 Spectrometers are crucial scientific instruments in various research fields and have consistently served as indispensable tools for foundational research. However, the unwieldy size of conventional spectrometers poses challenges for cost-effective and compact mobile platforms. In recent years, miniaturizing spectrometers based on spectral … Read more
A simplified diagram of the EnOC algorithm, with two dynamical ensemble members for simplicity. Here, the second (purple) ensemble member will receive a higher weight, since it is closer to the MISO forecast in the subspace. Note that in the real implementation, we reduce the dynamics in the MISO subspace to the first two principal … Read more
A wompoo fruit-dove in Queensland, Australia. Unraveling a genetic mystery revealed that flamingos and doves are more distantly related than previously thought. Credit: Daniel J. Field An enormous meteor spelled doom for most dinosaurs 65 million years ago. But not all. In the aftermath of the extinction event, birds—technically dinosaurs themselves—flourished. Scientists have spent centuries … Read more
Credit: Pixabay/CC0 Public Domain On a recent weekday, short but mighty flames began consuming an expanse of tallgrass in Illinois’ Nachusa Grasslands, their advance marked with crackles and pops. Satisfied with the blaze, a group of eight conservation workers split in two, walking the perimeter of a 124-acre square expanse of land. They used liquid … Read more
Tuning driving voltages for anomalously bright UCEL. Credit: USTC A research group has developed a new and highly efficient upconversion luminescence mechanism by scanning tunneling microscopy (STM) induced luminescence to observe an extraordinarily bright single-molecule upconversion electroluminescence (UCEL) phenomenon for the first time. The results are published in Nature Communications. UCEL is a kind of … Read more
