Abstract Most of current metal halide materials, including all inorganic and organic–inorganic hybrids, are crystalline materials with poor workability plasticity that limit their application scope. Here, we develop a novel class termed polymeric halides (PMHs) through introducing polycations into antimony‐based as A‐site cations. A series PMHs orange‐yellow broadband emission large Stokes shift originating from self‐trapped excitons successfully prepared, which meanwhile exhibit the...
The agricultural bioactivity of 7-alkenylcoumarin derivatives was investigated by synthesizing a series coumarin containing 7-styryl fragments introducing styryl group at the 7-position scaffold through Pechmann cyclization, substitution, bromination, and Wittig reaction. insecticidal effects antifungal activities these compounds against plant pathogenic fungi were evaluated. Bioactivity assessments revealed that compound 5i exhibited highest larvicidal activity Aedes aegypti, with mortality...
In this research, short cylinders of recycled aggregate concrete confined by basalt fiber reinforced polymer strips–polyvinyl chloride tubes mixture are taken as the object investigation, and a experimental study, finite element simulation theoretical analysis is applied. Through modifying volume quantity employed, axial compression studies were performed on concrete. The results demonstrate that variable spacing strips number strip layers have bigger effect load carrying capacity ductility...
Zero-dimensional metal halides have emerged a versatile platform for the development of light-emitting materials, but achieving tunable or even multicolor emission from material containing single type has proven highly challenging. Here, we leverage “structural tolerance” recently-developed polymeric to integrate two distinct coordination units into material, thereby optical properties in single-phase halides. By manipulating steric hindrance polycations, facilely adjustable green, red...

Elucidating the key factors that affect localized excitons (LEs) photoluminescence (PL) in lead-free metal halide nanocrystals (NCs) is important for their optoelectronic applications. However, effect of A-site cations on LEs based PL not well understood. Herein, we varied cation ratio (Rb/Cs) to investigate influence manganese-doped zinc chloride NCs. Through time-resolved (TR-PL) spectra and density functional theory (DFT) calculations, discovered Cl vacancy energetically more favorable...
Microstructural characterization of spontaneous combustion coal gangue (SCCG), the hydration products and mechanism concrete (SCCGC) were discerned through microscopic analysis. The bond performance was assessed employing a central pull-out test on samples variably substituted with SCCG (0%, 25%, 50%, 75%, 100%) augmented basalt fiber (BF) 0.1%, 0.15%, 0.2%). failure mode bonding also revealed by this test. bond-slip curves fitted various constitutive models suitable model found for each...
This research investigated the bond properties at high temperatures and with hybrid fiber addition between basalt reinforced polymer (BFRP) bars fiber-reinforced concrete (HFRC). The tensile strength appearance morphology of BFRP were analyzed. Used scanning electron microscopy (SEM) to examine microscopic used bond-slip constitutive model fit curves. When after exposed 300 °C, their dropped by 42%. With increasing temperature, stiffness normal (NC) specimens decreased 27.3 % 67.5 %,...
The numerical simulation of reinforced concrete deep beams with opening is analyzed by Finite Element Software ANSYS to establish reasonable mechanical model. stress characteristics and deformation's situation the are in under concentrated load different openings parts. purpose supply some favorable suggestions engineering application beam openings.
In order to set up analytical mode of shearing capacity deep beam and seek for more significant influencing factors, the factors have been analyzed by fuzzy comprehensive judgment, combine with theory set, compare select Method Determination Index Weight, determine weights each factors. The evaluation has proved be simple convenient analysis examples, results are approximately identical actual test, which comparable value in engineering application.
