The morphology of Gd(NO 3 ) / R -, S -AnempH 2 assemblies is controlled by solvent. spiral bundles (R-,S-1) are CPL active with asymmetric factor 2.8 times larger than that crystals (R-,S-2), while spindle-shaped particles (R-,S-3) inactive.
Helical architectures with controllable helical sense bias have recently attracted considerable interest for mimicking biological helices and developing novel chiral materials. Coordination polymers (CPs), composed of metal ion nodes organic linkers, are intriguing systems showing tunable structures functions. However, CPs morphologies rarely been explored so far. Particularly, chirality inversion through external stimulus has not achieved in CPs. In this work, we carried out an in-depth...
Lanthanide-based molecular materials showing efficient circularly polarized luminescence (CPL) activity with a high quantum yield are attractive due to their potential applications in data storage, optical sensors, and 3D displays. Herein we present an innovative method achieve enhanced CPL by doping chromophore ligand into coordination polymer superhelix. A series of homochiral europium(III) phosphonates helical morphology were prepared the formula S-, R-[Eu(cyampH)3-3n(nempH)3n]·3H2O...
Pine wilt disease (PWD) is one of the most destructive forest diseases that has led to rapid wilting and mortality in susceptible host pine trees. Spatially explicit detection wood nematode (PWN)-induced infestation important for management, policy making, practices. Previous studies have mapped disturbances response various and/or insects over large areas using remote-sensing techniques, but these efforts were often constrained by limited availability ground truth information needed...
A new theoretical-based constitutive model has been proposed in this study to concurrently predict the ageing and coupled creep-ageing behavior both micro macro ways of aluminum alloys under complex thermal mechanical loading histories. The nucleation, growth coarsening theories for age strengthening have modified with integration dislocation-based raised by plastic or creep deformation form modelling framework. Both key microstructures (precipitates, solid solutes dislocations) properties...
The micro-deformation monitoring radar is usually based on Permanent Scatterer (PS) technology to realize deformation inversion. When the region continuously monitored for a long time, image amplitude and pixel variance will change significantly with time. Therefore, it difficult select phase-stable scatterers by conventional deviation methods, as they can seriously affect accuracy of For different regions studied within same scenario, using PS selection method threshold often increases size...
When using ground-based synthetic aperture radar (GB-SAR) for monitoring open-pit mines, dynamic atmospheric conditions can interfere with the propagation speed of electromagnetic waves, resulting in phase errors. These errors are particularly complex rapidly changing weather or steep terrain, significantly impacting accuracy. In such scenarios, traditional regression model-based correction (APC) methods often become unsuitable. To address this issue, paper proposes a clustering method based...
Abstract The construction of helical nanotubes based on chiral coordination polymers (CPs) is an intriguing but challenging task, which important for the development functional materials that combine macroscopic chirality with tube‐related properties. Here, we selected a europium phosphonate system, e. g., Eu(NO 3 ) / R‐,S ‐pempH 2 , and carried out systematic work. By controlling hydrothermal reaction conditions such as pH value mixture, molar ratio concentration reactants, obtained...
The precise adjustment of handedness helical architectures is important to regulate their functions. Macroscopic chirality inversion has been achieved in organic supramolecular systems by pH, metal ions, solvents, chiral and non-chiral additives, temperature, light, but rarely coordination polymers (CPs). In particular, salt-assisted macroscopic not reported. this work, we carried out a systematic investigation on the role pH salt regulating morphology CPs based Gd(NO3)3...
Sand storm (SS) is highly concerned based on its adverse impacts environment and health. A field observation was conducted in Dingxing County within the Beijing–Tianjin–Hebei region from 16 March to 9 April 2021 covering two SS episodes evaluate PM2.5 components, health risks, sources. From non-SS period (NSSP) (SSP), more increase found PM10 (114 300 µg m–3) than (61.5 75.2 m–3), suggesting obvious increment of coarse particles (PM2.5–10) SSP. reconstruction indicated that higher dust 54.0...
Aiming at crack problems in hydraulic concrete structures, the rough set theory and decision tree analysis are integrated to analyze cause of propagation. Firstly, measured data chosen establish an initial information table. Secondly, continuous discretized by means analysis. Then, key factors were obtained from Lastly, implicit rules extracted out reduced table based on A case study shows that method can effectively extract relation between behavior external influencing factors.
