Zeolitic imidazolate framework (ZIF) glasses featuring nanoscale porosity have attracted significant attention due to their potential applications in catalysis, energy storage, gas sorption, and separation. However, mechanical properties may limit some of these applications. In this work, we investigate the structural origins variation zinc-based ZIF-62 (ZnIm2–xbImx) with different benzimidazolate (bIm) (Im) ratios. This is achieved using large-scale molecular dynamics simulations a recent...
Abstract Alkali‐free boroaluminosilicate glass (AFBG) is widely utilized in electronic display panels and fibers due to its superior mechanical properties thermal stability. The growing demand for high‐performance materials capable of withstanding extreme conditions has propelled the development AFBG. To this end, understanding relationship between composition, structure, at atomic level essential. This study investigates effects substituting B 2 O 3 alkaline earth metal oxides (RO) on...
Melting and glass formation of metal-organic frameworks (MOFs) allow them to be processed into bulk materials. However, two major challenges remain: only a small fraction MOF crystals undergo melting glass-formation, no well-established strategies exist for tuning structures properties. Here, we address both through co-melting zeolitic imidazole (ZIFs), subset MOFs, with heterocycle-based halide salts. The salt acts as chemical “modifier”, akin the role alkali modifiers in traditional...
A wavelet-based adaptive approach, called unsteady Reynolds-averaged Navier–Stokes (WA-URANS), is proposed to solve the URANS equations for computation of wall-bounded internal and external compressible turbulent flows. The new approach uses anisotropic mesh refinement, its effectiveness demonstrated flow simulations with two different turbulence models, namely, Spalart–Allmaras models a variety two- three-dimensional configurations arbitrary geometries, speed regimes, various boundary...
Abstract
Bulk LaFeSi magnets with the addition of LaAl alloy showing excellent performance were prepared by spark plasma sintering (SPS) technique. The effects heat treatment and various amounts on microstructure magnetocaloric properties investigated in details. It was found that appropriate can promote peritectic reaction, a high 1:13 phase amount be obtained. Due to unfavorable Al excess not beneficial formation phase. 5 wt.% most favorable Furthermore, had important performance. For SPSed LaAl,...
The volatile organic compounds emitted by plants significantly impact the atmospheric environment. impacts of drought stress on biogenic compound (BVOC) emissions are still under debate. In this study, effects two drought-rehydration cycle groups with different durations isoprene from Populus nigra (black poplar) seedlings were studied. P. placed in a chamber that controlled soil water content, radiation, and temperature. daily physiological parameters measured. emission rates (Fiso) reached...
Abstract New strategies for highly selective and sensitive detection of toxic environmental pollutants are still a pressing need. Here, through Cu 2+ metalated porous nanoscale covalent organic framework (NCOF), novel heterogeneous NCOF fluorescence probe has been synthesized selectivity hydrogen sulfide (H 2 S). Upon H S addition, the released from CuCOF, accompanied by recovered COF. As far as we know, not reported detection. The as‐prepared nano CuCOF displays an excellent response to...
Liquid-liquid phase separation (LLPS) is a prevalent phenomenon in silicate liquids. The ionic potential of the cations widely recognized as pivotal factor controlling immiscibility extent silicates; nonetheless, intricate relationship between two has yet to be fully understood. Here, using ab initio molecular dynamics simulations, we study static and dynamic structural evolutions prototypical LLPS system ($\mathrm{Ti}{\mathrm{O}}_{2}\text{\ensuremath{-}}\mathrm{Si}{\mathrm{O}}_{2}$), aiming...
