A new binuclear copper(II) complex, [Cu2Phen2Cl4] (Phen=1,10-phenanthroline), has been synthesized and characterized. Single crystal X-ray diffraction results suggest that this complex structure belongs to monoclinic crystal system, Cc (no. 9) with the cell dimensions: a=9.849(2)A, b=17.833(4)A, c=13.374(3)A, beta=106.61(3) degrees , V=2251.0(8)A(3),(More)
The interactions of fs DNA and two metal complexes [Cu(phen)SO4] x 2 H2O and [Ni(phen)SO4] x 2 H2O were explored by several chemometric methods, including parallel factor (PARAFAC), singular value decomposition-least squares (SVD-LS), and singular value decomposition-nonnegative least squares (SVD-NNLS) of excitation-emission matrix spectra (EEMs). The(More)
Sea water samples were collected in the East China Sea in March and April, 2005, and three-dimensional fluorescence of dissolved organic matter was measured by fluorescence excitation-emission matrix spectroscopy. The position, number and intensity of fluorescence peak in the spectra and the relations of the peaks were analyzed to determine the type,(More)
This study presents two GC-MS SIM methods, in combination with large-volume injection programmed-temperature vaporization (LVI-PTV) injection, for the determination of 141 pesticide residues in apple juice. The sample was extracted with ACN, and coextractives were removed with primary/secondary amine sorbent. ACN extract (20 microL) was injected into a PTV(More)
With field culture experiments and model calculations, the natural-light-dependent growth and the optimal light layers in sea water for growth of red tide dinoflagellate Prorocentrum donghaiense Lu were studied in order to analyze the role of light on algal blooms in the coastal area in East China Sea in spring. The results show that the relationship of(More)
Non-orthogonal joint diagonalization (NJD) free of prewhitening has been widely studied in the context of blind source separation (BSS) and array signal processing, etc. However, NJD is used to retrieve the jointly diagonalizable structure for a single set of target matrices which are mostly formulized with a single dataset, and thus is insufficient to(More)
The discrimination of phytoplankton classes using the characteristic fluorescence spectra extracted from three-dimensional fluorescence spectra was investigated. Single species cultures of 11 phytoplankton species, representing 5 major phytoplankton divisions, were used. The 3D fluorescence spectra of the cultures grown at different temperatures (20 and 15(More)
The supramolecular interaction of cucurbit(n=7)uril (Q[7]) with berberine chloride (BER) has been studied in aqueous solution at pH 2.0 and room temperature by spectro-fluorimetry. The association constant of the complex was 2.07 × 10(6) L mol(-1) calculated by using a nonlinear least squares method. (1)H NMR spectra confirmed that a 1:1 stable complex is(More)
Joint diagonalization (JD) is an instrumental tool in a vast variety of applications such as blind source separation, polarization sensitive array processing, and linear algebra based computation of tensor decompositions. Among the JD families, those based on successive rotations are a major category that minimizes the adopted highly nonlinear cost function(More)
Toxic effects of tributyltin (TBT) on the growth, peak diameter and photosynthetic activity (F(v)/F(m)) of fifteen predominant phytoplankton species in China coastal sea of Leptocylindru danicus, Skeletonema marinoi, Asterionella japonica, Bacilaria paxillifera, Chaetoceros debilis, Chaetoceros socialis, Thalassiosira, Amphidinium carterae, Karenia(More)
