Drought has become one of the major constraints to agricultural development, particularly in areas that lack water. Studying effects different water stresses on photosynthesis, growth, yield, use efficiency (WUE) and irrigation productivity (IWP) winter wheat will provide data for development scientific strategies water-saving methods. According size field capacity, four stress levels were set, i.e., 30–40% (severe stress), 40–50% (moderate 50–60% (mild stress) 60–80% (well-watered)...

Coupling two magnetic anisotropic lanthanide ions via a direct covalent bond is an effective way to realize high magnetization blocking temperature of single-molecule magnets (SMMs) by suppressing quantum tunneling (QTM), whereas so far only single-electron lanthanide–lanthanide bonds with relatively large distances are stabilized in which coupling between and the single electron dominates over weak 4f–4f coupling. Herein, we report for first time synthesis short Dy(II)–Dy(II) (3.61 Å)...

Currently, small object detection in complex remote sensing environments faces significant challenges. The detectors designed for this scenario have limitations, such as insufficient extraction of spatial local information, inflexible feature fusion, and limited global acquisition capability. In addition, there is a need to balance performance complexity when improving the model. To address these issues, paper proposes an efficient lightweight SCM-YOLO detector improved from YOLOv5 with...

Gold dendritic nanostructures with hyperbranched architectures were synthesized by the galvanic replacement reaction between nickel wire and HAuCl4 in aqueous solution. The study revealed that morphology of obtained strongly depended on experimental parameters such as solution concentration, temperature, time, well stirring or not. According to investigation growth process, it was proposed gold nanoparticles rough surfaces first deposited substrate subsequent preferentially occurred...

Metal complexes bearing single-electron metal-metal bonds (SEMBs) exhibit unusual electronic structures evoking strong magnetic coupling, and such can be stabilized in the form of dimetallofullerenes (di-EMFs) which two metals are confined a carbon cage. Up to now, only few di-EMFs containing SEMBs reported, all based on high-symmetry icosahedral (Ih) C80 cage embedding homonuclear rare-earth bimetals, chemical modification Ih-C80 is required stabilize SEMB. Herein, by introducing 3d-block...

Abstract Mercury's magnetopause is unique in the solar system due to its relatively small size and close proximity Sun. Based on 3 years of MErcury Surface, Space ENvironment, GEochemistry, Ranging orbital Magnetometer Fast Imaging Plasma Spectrometer data, mean location was determined for a total 5694 passes. We fit these locations three‐dimensional nonaxially symmetric which includes an indentation cusp region that has been successfully applied Earth. Our model predicts highly indented...

Abstract Observations show that in recent decades, a large area of China has been affected by drought and frequent droughts have caused damage to the ecological environment economy. Because differences data methods, assessing regional often leads contradictory conclusions trending. The self‐calibrated Palmer severity index (scPDSI) is based on multiple parameters, it considered regionally applicable widely used. However, some divergence observed results using different scPDSI_PM (scPDSI...

Metal–nitrogen double bonds have been commonly reported for conventional metal complexes, but the coexistence of both transition metal–nitrogen and lanthanide–nitrogen bridged by nitrogen within one compound has never reported. Herein, encapsulating a ternary metal-lanthanide heteronuclear dimetallic nitride into C84 fullerene cage, lanthanide-nitrogen are costabilized simultaneously as-formed clusterfullerene TiCeN@C1(12)-C84, which is representative clusterfullerene. Its molecular...

Abstract The Mercury is experiencing significant variations of solar wind forcing along its large eccentric orbit. With 12 years data from Surface, Space ENvironment, GEochemistry, and Ranging, we demonstrate that Mercury's distance the Sun has a great effect on size dayside magnetosphere much larger than temporal variations. mean standoff was found to be about 0.27 radii ( R M ) closer at perihelion aphelion. At subsolar magnetopause can compressed below 1.2 ~2.5% time. relationship between...

Encapsulating photoluminescent lanthanide ions like erbium (Er) into fullerene cages affords endohedral metallofullerenes (EMFs). Few reported Er-EMFs are all based on encapsulation of multiple (two to three) metal atoms, whereas mono-Er-EMFs exemplified by Er@C82 not due its narrow optical bandgap. Herein, entrapping an Er-cyanide cluster various C82 form novel Er-monometallic cyanide clusterfullerenes (CYCFs), ErCN@C82 (C2 (5), Cs (6), and C2v (9)), the properties CYCFs investigated,...

Abstract The dimensional limit of ferroelectricity has been long explored. critical contravention is that the downscaling leads to a loss polarization. This work demonstrates zero-dimensional by atomic sliding at restrained van der Waals interface crossed tungsten disufilde nanotubes. developed ferroelectric diode in this presents not only non-volatile resistive memory, but also programmable photovoltaic effect visible band. Benefiting from intrinsic limitation, allows electrical operation...

Halide perovskites exhibit remarkable properties, such as high optical absorption coefficient, excellent defect tolerance, simple and cheap preparation process, etc., especially radiation hardness, which makes them used in high‐energy ray environments. Free radicals, with singly occupied molecular orbitals, are highly reactive intermediates that play a critical role material degradation under radiation. However, the interaction between these radicals halide remains inadequately understood,...

Understanding the interplay between conformation and electronic properties of metal complexes at atomic level is key for rational design new functional molecules. Trimetallic clusterfullerenes (TMCFs) encapsulating quinary M3C2 carbide or M3NC carbonitride clusters offer an ideal model system elucidating conformation-electronic property correlation due to its unusual conformational versatility. Herein, we synthesize isolate two novel lanthanide-transition heteronuclear TMCFs, namely,...

Abstract Light‐lanthanides (Ln), despite their widespread uses in commercial permanent magnets, are among the least explored metal elements as building blocks of single‐molecule magnets (SMMs) due to smaller magnetic moments well weaker spin–orbit couplings than those heavy‐Ln counterparts, and so far, only a neodymium (Nd) complex has been reported showing small hysteresis at 2 K. Here, we report low‐coordination praseodymium (Pr) complex, namely, Pr@C 81 N, featuring non‐Kramers trivalent...
