Department of Chemistry, National Institute or Technology, Tiruchirappalli-620 015, India School of Chemical and Biotechnology, SASTRA Deemed University, Thanjavur-613 402. India <em>E-mail</em> : angum@nitt.edu <em>Manuscript received 3 September 2003, revised 23 June 2004, accepted 2 February 2005</em> A new Mannich base, piperazino-his(methylantipyrine) (PBMA), was synthesized and characterized by spectral studies. Chelates of PBMA with chromium(III), manganese(ll), cobalt(II), copper(II), zinc(II) and cadmium(II) ions were prepared and characterized by elemental analyses and IR, UV and <sup>1</sup>H NMR spectral studies. PBMA was found to act as a bidentate ligand bonding through one of the carbonyl oxygens of antipyrine and one of the C-N-C groups of piperazine moiety. Based on the magnetic moment values and UV-Vis spectral data, trigonal bipyramidal geometry for&middot; chromium(lll), distorted octahedral geometry for copper(II) chloro and bromo complexes and tetrahedral geometry for cobalt(II), zinc(II) and cadmium(ll) chloro and bromo complexes were assigned. TG and DTA studies show a double stage decomposition pattern for PBMA and its chromium(lll), cobalt(II) and cadmium(II) chloro complexes and a single stage decomposition pattern for zinc(ll) bromo complex. The kinetic and thermodynamic parameters for the thermal decomposition of the metal chelates were evaluated using equations based on integral methods. The antimicrobial studies show that the zinc(ll) complexes arc more active than the other complexes.

ABSTRACT. Zinc(II), cadmium(II), tin(II), lead(II) and antimony(III) complexes of creatinine with the composition of [M(creat)2Xn].xH2O, (X = Cl or NO3; n = 2-6) were prepared. The complexes were characterized by analytical and spectral methods. The analysis of FT-IR and Raman spectra helps to understand the coordination properties of the creatinine ligand and to determine the probable structure of the complexes. The shift in the resonances of cyclic NH proton in the 1H NMR when compared to the ligand indicated that cyclic nitrogen coordinates. Conductivity measurements in DMSO suggested that the complexes are non-electrolytes. Thermal decomposition behavior of the complexes was also discussed.&#x0D; &#x0D; KEY WORDS: Creatinine, TGA/DTA, Metal complexation, Raman spectroscopy&#x0D; &#x0D; Bull. Chem. Soc.

Abstract:
Synthesis of zinc(II)/cadmium(II)/mercury(II) thiocyanate and azide complexes of a new bidentate Schiff-base ligand (L) with general formula of MLX2(M = Zn(II), Cd(II), and Hg(II)) in ethanol solution at room temperature is reported. The ligand and metal complexes were characterized by using ultraviolet-visible (UV-visible), Fourier transform infrared (FT-IR),1H- and13C-NMR spectroscopy and physical characterization, CHN analysis, and molar conductivity.1H- and13C-NMR spectra have been studied in DMSO-d6. The reasonable shifts of FT-IR and NMR spectral signals of the complexes with respect to the free ligand confirm well coordination of Schiff-base ligand and anions in an inner sphere coordination space. The conductivity measurements as well as spectral data indicated that the complexes are nonelectrolyte. Theoretical optimization on the structure of ligand and its complexes was performed at the Becke’s three-parameter hybrid functional (B3) with the nonlocal correlation of Lee-Yang-Parr (LYP) level of theory with double-zeta valence (LANL2DZ) basis set using GAUSSIAN 03 suite of program, and then some theoretical structural parameters such as bond lengths, bond angles, and torsion angles were obtained. Finally, electrochemical behavior of ligand and its complexes was investigated. Cyclic voltammograms of metal complexes showed considerable changes with respect to free ligand.

Abstract:
Anhydrous monophenylphosphinates of manganese(II), Mn[H(C₆H₅)PO₂]₂ (Form I, Form II and Form 1(B)) and cadmium(II), Cd[H(C₆H₅)PO₂]₂ (Form I and Form II) were synthesized and characterized by solubility tests, Differential Scanning Calorimetry (DSC), Infrared Spectroscopy, X-ray Powder Diffractometry, Electron Spin Resonance (ESR) spectroscopy, magnetic susceptibility measurements and Electron Spectroscopy for Chemical Analysis (ESCA). These materials are considered to be polymeric with metal ions connected in chains by double bridging phosphinate groups with cross-linkage forming sheets and octahedral metal centers. Magnetic susceptibility studies showed that Mn[H(C₆H₅)PO₂]₂ (Form I) exhibits relatively strong antiferromagnetic exchange interactions (J is about -4.50 cm⁻¹) and the effects on this magnetic exchange of doping diamagnetic cadmium ions into the material have been investigated. A series of mixed metal phosphinates of the form Mn₁₋x Cdx [H(C₆H₅)PO₂]₂ (Form I) where x=0 to 1.00 were prepared and investigated. The effect of doping with cadmium is to break the infinite manganese(II) monophenylphosphinate chain into finite segments and to generate monomer impurities in odd numbered segments. As the extent of doping is increased the average chain length decreases and the fraction of monomer increases. In addition, the exchange coupling constant, J, was found to decrease (from -4.50 to -2.70 cm⁻¹) as the average chain length decreases. Mn[H(C₆H₅)PO₂]₂ (Form 1(B)), which is precipitated from concentrated solutions, contains much shorter chain fragments than the pure Form I material. Mn[H(C₆H₅)PO₂]₂ (Form II) has a distinct infrared spectrum and X-ray powder diffraction pattern and shows much weaker antiferromagnetic behavior (J is about -2.40 cm⁻¹) than the Form I compound. Magnetic studies suggest that in this compound the average chain length is significantly smaller than in Mn[H(C₆H₅)PO₂]₂ (Form I). The hydrated monophenylphosphinates of manganese(II), Mn[H(C₆H₅)PO₂]₂•H₂0 and Mn[H(C₆H₅)PO₂]₂•2H₂0, were synthesized and characterized in this work. The structures of these compounds are considered to be similar to those of the anhydrous materials except in the hydrated compounds one or two of the metal coordination sites are occupied by water molecules. The dihydrate shows only very weak antiferromagnetic properties (J is about -0.50 cm⁻¹). The diphenylphosphinates of manganese(II) and cadmium(II) were also prepared and characterized. The infrared spectra and X-ray powder diffraction patterns for these materials are distinct from each other,which indicates the compounds are not isomorphous. Only rather weak magnetic exchange was observed in the manganese compound. Zn[H(C₆H₅)PO₂]₂ has also been synthesized and partially characterized in this work. The infrared spectrum and X-ray powder diffraction pattern obtained for this compound are unique among all the metal phosphinates studied in this work.<br>Science, Faculty of<br>Chemistry, Department of<br>Graduate

Full text
Abstract:
Spectral and kinetic studies made on CoPc over a concentration range of 1.72 x 10-6M – 1.00 x 10-5M in DMSO are consistent with a monomer-dimer equilibrium at 303 K. The dimerization constant obtained at 303 K is 1.67 x 104M-1 and is two to three orders of magnitude smaller than those of several tetrasulfonated metallophthalocyanines in aqueous solution. The rate constants for the formation and dissociation of the CoPc dimer in DMSO at 303 K are 1.29 x 102M-1s-1 and 7.20 x 10-3s-1, respectively. The low dimerization constant for CoPc in DMSO is attributed to its relatively slow rate of dimer formation. Introduction of cyanide, detergents, and salts to solutions of CoPc in DMSO all enhanced the dissociation of the CoPc dimer. Furthermore, both cyanide and the catonic detergent cetyl trimethylammonium bromide (CTAB) at concentrations of 6.0 x 10-2M and higher, facilitate oxidation of cobalt in CoPc. For cyanide, this is accomplished by destabilization of the metal eg electrons by back-bonding in the axial positions of CoPc while the CTAB detergent forms a micelle which encapsulates a CoPc monomer striping the dye of axial DMSO molecules in the process. Thus, oxygen can bind to the vacant axial positions on the metal. Kinetic studies of the interactions between cyanide and CoPc in DMSO show two fast reactions which are attributed to the addition of cyanide to the axial positions of CoPc. The rate constants for the addition of the first and second cyanide ligands to CoPc are 7.72 x 105M-1s-1 and 5.51 x 104M-1s-1, respectively, at 299 K. Activation parameters, ΔHs* and ΔSs* for the second cyanide addition are 9.9 kcal/mol and -4.0 e.u., respectively. Both additions are faster than the corresponding reactions with CoTSPc4- in DMSO. The three detergents sodium dodecyl sulfate (SDS), Triton X-100, and cetyl trimethylammonium bromide (CTAB) dissociate the CoPc dimer more than by dilution with DMSO. Furthermore, Triton X-100 dissociates the CoPc dimer at about the same rate as CTAB while SDS is not as efficient at comparable concentrations to CTAB. The critical micelle concentration for the CTAB-DMSO system is reached at a CTAB concentration of 6.0 x 10-2M where the CoPc dimer dissociation rate nearly triples compared to solvent dilution and oxidation of the metal in CoPc is observed. The addition of tetraethylammonium bromide, tetrapropylammonium bromide and tetrabutylammonium bromide to CoPc in DMSO increases the dimer dissociation rate by a factor of two compared to dilution with DMSO. All salts dissociate the CoPc dimer at similar rates suggesting the hydrocarbon chain is of insufficient length to be as effective as CTAB. Finally, oxygen does not seem to effect the dissociation of the CoPc dimer in DMSO

Abstract:
This chapter refers to the study of the biosorption of Ni(II) and Cd(II) in packed bed bioreactor by Pseudomonas putida. The conventional treatment methods of Nickel and Cadmium were elaborated and compared with biosorption. The methods for optimization of process conditions for biosorption of Ni(II) and Cd(II) in packed bed bioreactor by Pseudomonas putida were explained. The optimum conditioned were determined to be flow rate of 300 mL/h, initial metal ion concentration of 100 mg/L and bed height of 20 cm with weight of biosorbent of 12 g, and it was found that the Agar immobilized Pseudomonas putida showed maximum percent biosorption and bed saturation occurred at 20 minutes. Optimization results of Ni(II) and Cd(II) by Pseudomonas putida from the Design Expert software were obtained as bed height of 19.93 cm, initial metal ion concentration of 103.85 mg/L, and flow rate of 310.57 mL/h. The percent biosorption of Ni(II) and Cd(II) is 87.2% and 88.2% respectively. The predicted optimized parameters are in agreement with the experimental results. Experiments were carried out at established optimum conditions of bed height of 20.77 cm, flow rate of 309.09 mL/h, and initial metal ion concentration of 109.23 mg/L and results of biosorption of Ni(II) and Cd(II) were reproduced and they were in agreement with the predicted results. Based the experimental results, it was observed that the Pseudomonas putida was the best choice to remove Nickel and Cadmium ions from wastewater in a continuous column system.

Abstract:
The aim of the chapter is to review aspects of the analysis of cardio-respiratory interaction using spectral estimation methods. The first section of the paper provides background on nonlinear physiological oscillation, entrainment phenomena and computer modelling. Entrainment phenomena are described in some detail including: frequency pulling and nonlinear modulation. These phenomena are illustrated using the examples of respiratory sinus arrhythmia and the baro-receptor reflex. ARMA and AR techniques are reviewed and compared to the FFT. Experimental results on the interaction of heart rate, blood pressure and respiration are presented; it was shown that ARMA techniques provided evidence of short term independent physiological mechanisms whereby respiration affects heart rate and blood pressure. In the second section of the chapter time-frequency representations are introduced and the Short-Term Fourier Transform (STET), Wigner&amp;ndash;Ville Distribution (WVD) and wavelet transforms are compared on a theoretical basis and applied to heart rate and respiration data, as well as test data, to highlight their differences. The first section of this part of the chapter points out a number of apparently complex phenomena in blood pressure, respiration and heart rate waveforms. These phenomena were shown to be more clearly understood by the application of nonlinear dynamic theory, coupled to computer modelling. In the second section the main advantages of the time-frequency methods were highlighted. These are their robustness and the fact that these methods do not require the data being analyzed to be stationary and as such represent an important development in the beat-to-beat study of cardio-respiratory control.

Abstract:
Viable Saccharomyces cerevisiae cells were immobilized by silicaalginate matrix and obtained spherical composite particles and used for biosorption of Cd(II) ions. The obtained composite displayed high cadmium removal efficiency of 99.2, 95.7, 88.3 and 78% in the successive four adsorption steps. The adsorption capacity after four step of Cd(II) removal was ~14,2 mg of Cd(II) per g of biosorbent. Pseudo-second-order kinetic agree well with the experimental values suggesting both adsorption and ionic exchange are simultaneously performed on the surface of used biosorbent.

Abstract:
Recent studies of the photorefractive response of CdTe have demonstrated it to be a highly sensitive material with a broad near infrared sensitivity extending to beyond 1.5 μm[1,2]. Desirable parameters, such as large electrooptic coefficient, small dielectric constant, large carrier mobility and availability in semi-insulating form, makes CdTe a potential material of choice for many applications[3]. This study focuses on photorefractive characterization of Bridgeman grown crystals with the goal of providing the information that can lead to the optimization of key photorefractive parameters. We have observed gain and broad sensitivity (1-1.5 μm) in vanadium doped CdTe and Cd0.96Zn0.4Te samples. Mixed alloys such as CdZnTe and CdMnTe allow band gap engineering such that the sensitivity range could be tuned toward the visible and be matched to the wavelength of interest. An applied alternating (AC) field gain enhancement technique is used to demonstrate net gain which is a prerequisite for coherent amplification and self-pumped phase conjugation.
