Abstract For gas separation and catalysis by metal‐organic frameworks (MOFs), diffusion has a substantial impact on the process' overall rate, so it is necessary to determine molecular behavior within MOFs. In this study, an interpretable machine learing (ML) model, light gradient boosting (LGBM), trained predict diffusivity selectivity of 9 gases (Kr, Xe, CH 4 , N 2 H S, O CO He). these gases, LGBM displays high accuracy (average R = 0.962) superior extrapolation for C 6 . And model...
Designing a novel adsorbent with high selectivity and absorptive capacity to remove I2 remains challenging task. In this work, series of porphyrin-based hyper-cross-linked porous organic polymers (PHCPs) dual hydroxy-rich structure were synthesized by the Friedel–Crafts reaction. PHCPs exhibit excellent thermal stability. The incorporation abundant π-electrons heteroatoms (N/O) in framework leads substantial charge transfer interactions iodine, resulting adsorption (469 mg g–1) rapid...

In this work, high‐throughput computing screening and machine learning employed to evaluate the CO 2 performance of 54117 MMMs composed 9 polymers 6013 metal–organic frameworks (MOFs). The structure‐property relationships analyzed 4 binary mixtures (CO /X, X = CH , N H O ), best‐performing combinations MOFs found, with which MMM exceeded Robeson's upper limit. Then, a stacked ensemble...

Abstract In this article, we discuss a nondifferentiable nonlinear penalty method for an optimization problem with inequality constraints. A smoothing is proposed the nonsmooth function. Error estimations are obtained among optimal value of smoothed problem, and that original constrained problem. We give algorithm based on prove convergence algorithm. The efficiency illustrated numerical example.
With the rapid growth of economy, people are increasingly reliant on energy sources. However, in recent years, crisis has gradually intensified. As a clean source, methane garnered widespread attention for its development and utilization. This study employed both large-scale computational screening machine learning to investigate adsorption diffusion properties thousands metal–organic frameworks (MOFs) six gas binary mixtures CH4 (H2/CH4, N2/CH4, O2/CH4, CO2/CH4, H2S/CH4, He/CH4)...
A new sensitive method for antimony (III) determination by graphite furnace atomic absorption spectrometry (GFAAS) has been developed using N-benzoyl-N-phenylhydroxylamine (BPHA) and 1-butyl-3-methylimidazolium hexafluorophosphate ([C 4 mim][PF 6 ]) single drop microextraction.

Abstract Most traditional D 2 /H separation techniques are energy‐intensive with low efficiency. Metal–organic frameworks (MOFs) provide a promising solution for due to their excellent chemical and structural characteristics. Here, machine learning‐assisted high‐throughput computational screening was employed identify the high‐performance MOFs dynamic separation. Extensive data analysis reveals that there were two adsorption behaviors in optimal MOFs, independent competitive adsorption,...
