Nanopesticides were selected as one of the top 10 emerging technologies in chemistry that will change our world 2019. Facile, smart, and degradable metal–organic framework MIL-101(FeIII) nanopesticides gated with FeIII-tannic acid (TA) networks are created using a universal strategy. The capping FeIII-TA network gatekeepers is instinctively oriented by coordinatively unsaturated FeIII sites on surfaces nanocarriers; thus, their combination perfectly matched. This first example smart...
Mesoporous silica nanoparticles (MSNs) can be designed to effectively load, protect, and control the release of pesticides. In this study, emulsion-solvent evaporation was used fabricate abamectin-loaded MSNs. Our method could deliver abamectin in process MSN self-assembly, resulting simple operation, short preparation period, outstanding drug carrying capacity. The characteristics MSNs, including morphology, loading content, stability against photolysis, controlled behavior, toxicological...
Complete pesticide nanocapsules were readily prepared through an "on site" FeIII-tannic acid (TA) coordination assembly based on oil/water microemulsions stabilized with different types of surfactants and various pesticides dissolved in the oil phase after only one deposition cycle Fe3+ TA. This is a universal strategy suitable for independent addition sequence Surprisingly, smart showed multidimensional on-demand controlled release (including acidic pH, alkaline glutathione, ascorbic acid,...
Facile pesticide nanocapsules were successfully prepared by directly encapsulating the antisolvent precipitation of pesticides through instantaneous "on site" coordination assembly tannic acid and Fe3+, avoiding tedious preparation, time consumption, large amounts organic solvents. The showed excellent resistance to ultraviolet photolysis rainwater washing owing nanocapsule walls. smart exhibited controlled release under multidimensional stimuli, such as acidic/alkaline pH, glutathione,...
Water contaminated with heavy metal ions poses serious threat to the human health and environment protection. It is imperative develop analytical tools detect ions. Herein, we propose autofluorescence free SiO2 modified upconversion nanosensor for label-free fast determination of MnO4- Cr2O72- anions. The highly efficient multi-colour luminescence (UCL) UCNPs@SiO2 was effectively quenched by anions response time 2 1 min, respectively. exhibits linear detection ranges 0.6-2000, 2-2000 µM LOD...
Abstract As an eco‐friendly technology for pavement preventive maintenance, microsurfacing (MS) has the potential properties of cost‐saving and excellent performance benefits in repairing distress. MS also improves surface function, especially skid resistance, old pavements that have gradually decayed under coupled effects long‐term environment loads. Reasonable assessments wear resistance can provide support accurate decision‐making on which turn reduces maintenance costs saves costs,...
Polyvinyl alcohol (PVA) concrete is a new green building material. In order to make it more widely used, this study used butylbenzene emulsion (SBL) modify PVA fiber concrete. The enhancement mechanism of SBL on the PVA/cement interface was systematically investigated at multiple scales, including macroscopic mechanical properties, microstructural characteristics, nano-interface interactions. On macro scale, addition and fibers can significantly improve shear strength flexural composite 7 28...

The effects of grain boundary on the deformation behavior magnesium bicrystals under tensile loading are investigated using molecular dynamics simulation method. Deformation mechanisms both asymmetric and symmetric studied. results show that twist angle could exert a significant influence flow stress in plastic stage. It is found property bicrystal much better than counterpart. In addition, for bicrystalline metal with large angle, its response small owing to dislocation nucleation activity region.
Due to the organic porous nature of expanded polystyrene (EPS) foam concrete, bond strength between it and cement is weak, leading a weakened interface transition zone low strength. However, most studies on this issue have been limited phenomenological approaches, neglecting role atomic-level mechanisms. Therefore, study combines macroscopic microscopic experiments, as well molecular dynamics, investigate mechanisms silane coupling agent (SCA) enhancing performance EPS-concrete. Macroscopic...
This study employs polyvinyl alcohol (PVA) fibers and silane coupling agent (SCA) to augment rubberized concrete mechanical prowess. A multiscale investigation delves into the synergistic enhancement mechanism of SCA on interfaces PVA/cement rubber/cement, considering macroscopic properties, microscopic structural characteristics, nanoscale interface interactions. Initially, fundamental performance tests reveal a notable in compressive flexural strength with inclusion PVA concrete....
The feasibility of PVA fiber rubber concrete modified by modifier in the structure was investigated using portal frame as research object. basic mechanical properties materials were tested mechanically first, and then ABAQUS used to establish ordinary model, after confirming model’s rationality, concrete, models established on this basis, displacement strain comparison analysis with carried out. simulation results show that material can improve large deformation treated a structural strength...
