Emissions from industrial activities pose a serious threat to human health and impose the need for monitoring both inorganic and organic pollutants in industrial areas. We selected Masson pine (Pinus massoniana L.) as potential biomonitor and collected the current (C) and previous year (C+1) needles from three industrial sites dominated by petrochemical,(More)
Based on the dramatic accelerating effect of 2-aminophenol, three ligands derived from 2-aminophenol were developed. Copper-catalyzed coupling reaction of nitrogen-containing nucleophiles with aryl bromides was efficiently carried out under mild conditions using 1,2,3,4-tetrahydro-8-hydroxyquinoline as a novel, simple, and versatile ligand.
Tests for dispersion effects in replicated two-level factorial experiments assuming a location-dispersion model are presented. The tests use individual measures of dispersion which remove the location effects and also provide an estimate of pure error. Empirical critical values for two such tests are given for two-level full or regular fractional factorial(More)
We present efficient and stable numerical methods for approximations of the generalized Zakharov system (GZS) and vector Zakharov system for multicomponent plasma (VZSM) with/without a linear damping term. The key points in the methods are based on (i) a time-splitting discretization of a Schrödinger-type equation in GZS or VZSM, (ii) discretizing a(More)
The natural abundance of 13C and 15N can integrate information on the dynamics of C and N, respectively. This study tested whether and how δ13C and δ15N of the plant and soil samples (including leaf, forest floor litters, fine roots, and 0–15 cm mineral soil) can detect local variations in community biomass, litter production, and litter turnover rate were(More)
Single-mode laser is realized in a cesium lead halide perovskite submicron sphere at room temperature. All-inorganic cesium lead halide (CsPbX3, X = Cl, Br, I) microspheres with tunable sizes (0.2-10 μm) are first fabricated by a dual-source chemical vapor deposition method. Due to smooth surface and regular geometry structure of microspheres, whispering(More)
