Pb2+-doped Cs2Mn(Cl/Br)4·2H2O PA NCs exhibit excellent luminescence properties and stability, and can be used in fibers and other uses.

Cs2Sn1−xTexCl6 crystals are synthesized and can be used for post-processing fibers for LED and anti-counterfeiting materials.

The 6Li(16O,19Ne*)3H multi-nucleon transfer-reaction experiment was performed to populate the highly excited states in 19Ne. The subsequent decay particles, 4He or proton from the 19Ne resonant states, were detected in coincidence with the recoil 3H. The excitation-energy spectra of 19Ne were reconstructed by using the detected proton or 4He and the deduced 18F or 15O, respectively. The broad resonance at about 7.85 MeV (1/2+) was observed with partial decay widths updating the previously reported values, which may have significant impact on the destruction of 18F in astrophysical processes. Several resonances up to very high excitation energies have been identified with large α-clustering strength, which confirm the formation of the cluster structure with one-hole configuration in light nuclei, and encourage further systematic studies of cluster structure in 19Ne.

In the blending process of the composites, the clustering of MWCNTs under high concentration leads to poor dispersion and difficult complexing with luminescent elements. Cyanate ester resins (CERs) have a brittle network structure when cured caused by a conjugation effect that forms a strong emission peak in the ultraviolet-visible region and quenches the luminescent elements of the fluorescent nanofillers. In this paper, by anchoring of the Eu complex (Eu(TTA)

Context. The Full-disk Vector MagnetoGraph (FMG) is one of the three payloads on the Advanced Space-based Solar Observatory (ASO-S). The FMG is set to observe the full disk vector magnetic field at a single wavelength point. The magnetograph in orbit will encounter the wavelength shift problem caused by the Doppler effect in the magnetic field, which mainly comes from the Sun’s rotation velocity and the satellite–sun relative velocity. Aims. We look to use neural networks for single-wavelength calibration to solve the wavelength shift problem. Methods. We used the existing data from the Helioseismic and Magnetic Imager (HMI) on the Solar Dynamics Observatory (SDO). To simulate plausible single-wavelength observations, we used the Stokes polarization image from the HMI at a single wavelength point. We also input the satellite orbital velocity given by the HMI data file and the solar rotation velocity to the network. We developed a set of data preprocessing methods before entering the network and we trained the network to get the calibration model. Results. By analyzing and comparing the prediction of the neural network with the target magnetogram, we believe that our network model has learned a single-wavelength full-disk calibration model. The mean absolute error (MAE) of the longitudinal field and the transverse field of the full disk are 3.68 G and 28.08 G, respectively. The MAE error of the azimuth angle of pixels above 300 G is 12.29°.
