ABSTRACT To investigate the contaminant characteristics of heavy metals in soils and vegetables surrounding a lead-zinc mine in Huize County, Yunnan Province, thirty surface soil samples and
A Quantum Chemistry Study on the Mechanism of the Reaction Between NH and O_3
The mechanism of the reaction NH +O3→HNO +O2 has been studied by density functional theory (DFT) at the B3LYP method and 6 - 31+ +G** level. The geometries of reactants, transition states,
Preparation and Performance of a De-tert-butyl-calix[8]arene-bonded Stationary Phase for HPLC
A calix[8]arene-bonded gel silica stationary phase(DCABS) was prepared by using coupling reagent(KH560). Its structure was characterized by FTIR, elemental analysis and thermal analysis. The
Theoretical Study on the Hydrogen Bond of NH_3·(H_2O)
Ab initio method has been employed to study hydrogen bond properties of NH 3·(H 2O)complexes, the bond energy and the bond length have been calculated at the DFT theory level for different basis sets
Study of Interaction of p-(N,N′-Dimethylaminomethyl)-calix[8]arene with DNA Using Methylene Blue as Spectroscopic Probe
The interaction of water soluble p (N,N ′ dimethylaminomethyl)calix\arene(CX8) with calf thymus DNA has been studied by UV vis spectroscopy and fluorescence spectrophotometry using methylene blue(MB)
Molecular Recognition Interaction of Perhydroxycucurbit[6]uril with p-Aminobenzenesulfonic Acid by Spectroscopic Methods
The inclusion interaction of perhydroxycucurbit[6]uril(HOCB6) with p-aminobenzene sulfonic acid(ABS) was studied by UV spectroscopic and fluorimetric methods.Several effect factors,such as the pH
