Roxarsone, an organoarsenic compound serving as a common feeding additive in poultry industry, brings about potential risk of the toxic inorganic arsenate contamination in ambient environment. Current understanding in the dynamics of roxarsone removal and the determining environmental processes remains unclear, thus restricts the progress in(More)
Highly dispersed palladium chloride catalysts locked in triphenylphosphine-functionalized knitting aryl network polymers (KAPs) are developed and exhibit excellent activity under mild conditions in the Suzuki-Miyaura cross-coupling reactions of aryl chlorides in aqueous media. This work highlights that the microporous polymers not only play the role of(More)
The semi-implicit time stepping scheme in non-hydrostatic compressible atmosphere model makes it necessary to solve 3-D helmholtz equations, which are complicated with variable coefficients and cross derivative terms. Since the ill-conditioned matrix is nonsymmetric, preconditioned GMRES Krylov iterative algorithm is adopted. Based on PETSc and Hypre(More)
Hierarchical nanocrystalline ZSM-5 zeolite (NZ5) was synthesized at 100 °C under atmospheric pressure using methylamine as a mineralizing agent. The crystallization process of NZ5 was characterized by dynamic light scattering (DLS), X-ray diffraction (XRD), and infrared spectroscopy (FTIR). The results of contrastive experiments showed that evaporation of(More)
Glycerol carbonate can be readily synthesized from the oxidative carbonylation of glycerol catalyzed by PdCl(2)(phen) (phen=1,10-phenanthroline) with the aid of CuI. High conversion (95 %) and selectivity (98 %) are achieved and the turnover frequency (TOF) reaches 455 h(-1). Furthermore, a new zeolite-Y-confined Pd catalyst, PdCl(2)(phen)@Y, has been(More)
