Peptides are one of the best candidates for drug development due to their high specificity and low toxicity and porphyrins are significant macromolecules in biological systems with important roles. In this works ynthesis of dipeptide (histidine-β-alanine) was done by solid-phase peptide synthesis method (SPPS) and tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) was synthesized by Adler method. The molecular structure of the dipeptide and porphyrin was defined by using different methods such as UV-Vis, FT-IR, 1H NMR and LC-Mass spectrometry for dipeptide. Kinetics study and comparison of the chelating ability of dipeptide (histidine-β-alanine) and TPPS4 was investigated for removing of metal ions Al3+, Cu2+, Hg2+ and Pb2+ in vitro.

A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol was selected as the extraction solvent. The factors affecting the extraction efficiency of DLLME-SFO such as the volume of the extraction solvent, kind and volume of the disperser solvent, effect of concentration of KBr, KBrO3, H2SO4 and time of centrifuge, time of derivative and extraction time were investigated and the optimal extraction conditions were estimated. Under the optimum conditions (extraction solvent: 150µl 1-undecanol;disperser solvent:1000 µl acetone; concentration of KBr, KBrO3:10 ppb; concentration of H2SO4 0.001 mol/l; extraction time: 3min), calibration curve is linear in the range of 0.5-15 ppb and correlation of determination (R2) is 0.993.The method was successfully applied for the determination of acrylamide in the actual potato chips.

Multiwalled Carbon Nanotube (MWCNT) reinforced silica aerogel was synthesized in a very simple and cost effective sol - gel method. The process was followed by ambient pressure drying, and then the aerogel material was characterized by XRD, BET, SEM, EDX and FT-IR. 2.3 x 10-3 wt% MWCNTs were successfully incorporated in sodium silicate based silica aerogel. This metal-free nanocomposite catalyzed a four component organic reaction among 4-hydroxy coumarin, benzaldehyde, phenyl hydrazine, and ethyl acetoacetate for synthesizing medicinally important benzylpyrazolyl coumarin at room temperature. The MWCNT/silica aerogel composite material having easy accessible active sites and high catalytic activity was easily recovered and reused. The aerogel composite when impregnated with ceria offered very efficient and selective reaction methodology.

In this study, a nickel (II) complex with 1,10-phenanthroline based ligand, [Ni(FIP)2](OAC)2 (1) with FIP = 2-(Furan-2-yl)-1H-Imidazole[4,5-f][1,10] phenanthroline as ligand was synthesized and characterized by spectroscopic methods and elemental analysis. The interaction of [Ni(FIP)2](OAC)2 (1) with calf-thymus DNA (ct-DNA) was studied by UV-vis absorption, fluorescence spectroscopies and viscosity measurements in 20 mM Tris/HCl buffer solution, pH 7.0 at 25 °C. The complex (1) interacts with ct-DNA with an intrinsic binding constant of 1.11 ×105 M-1. Furthermore, the thermodynamic studies suggested that the interaction processes were endothermic disfavored (ΔH >0) and entropy favored (ΔS >0). The viscosity studies showed no considerable increasing changes in the viscosity of ct-DNA with increasing of the complex (1) concentration. Therefore, the [Ni(FIP)2](OAC)2 complex bind to ct-DNA via hydrophobic interaction as the main forces acting during the binding processes and the mode of binding is groove binding which was illustrated by hyperchromism in the UV-vis absorption band of [Ni(FIP)2](OAC)2 (1) with addition of ct-DNA and the decreasing of ethidium bromide (EB)-ct-DNA complex fluorescence in the presence of different concentrations of [Ni(FIP)2](OAC)2 complex and the unchanged viscosity of ct-DNA.

In this work, the ability of the MgCaFe- Layered double hydroxide (LDH) for congo red (CR) dye removal in aqueous solution was investigated. Various parameters such as initial dye concentrations, temperature, adsorbent dosage, pH effect and agitation rate were examined and optimal conditions (10 mgL-1 of the dye concentration, 25 °C of temperature, 0.5 gL-1 of the adsorbent dosage, pH~7 and 450 rpm of agitation rate) were obtained. Moreover, the reusability of the adsorbent was investigated and promising result was obtained. Furthermore, the result showed the adsorption data on optimal condition was found to follow the pseudo- second order kinetic model with a high degree of correlation coefficient. Summary, this research illustrated that the MgCaFe-LDH can be used as efficient adsorbent for removing anionic dye in waste water.

Nanosized hydroxyapatite (HA) powders have been synthesized by an inverse microemulsion system using cyclohexane, an anionic surfactant and aqueous solutions of calcium nitrate tetrahydrate and biammonium hydrogen phosphate in the presence of anionic and caionic polyelectrolyte with the inducement of ultrasound irradiation. Prepared HA in presence of anionic polyelectrolyte has a different morphology from samples which are synthesized in presence of cationic polyelectrolyte. Cationic polyelectrolyte (poly diallyl dimethyl ammonium chloride PDADMAC) leads to formation of needle-like HA (10nm in diameter and 100nm in length). Formation of HA at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the HA samples were characterized using transmission electron microscopy (TEM).

The present work describes, the reaction between disodium salt of 1,3-dihydroxybenzene (in situ formation) and propargyl bromide was carried out in a solid-liquid biphasic phase transfer catalytic system at 50°C. Higher selectivity of the bis-derivative (1,3-bis(prop-2-ynyloxy)benzene) was obtained under solid-liquid PTC condion. The conversion of propargyl bromide of more than 99% was achieved in the presence of tetra-n-butylammonium bromide (TBAB) as catalyst. From the experimental evidence there is no mono-dervative observed. Experiments were conducted to increase the conversion of propargyl bromide such as, stirring speed, various PTCs, temperature, various solvents and amount of TBAB loading. All the experiments were conducted to obey pseudo-first order rate law. Apparent activation energy was also determined from the Arrhenius plot.

ZrOCl2.8H2O@nano SiO2 has been synthesized for the first time via a simple procedure and characterized by SEM (scanning electron microscopy), FT-IR, and EDX (energy-dispersive X-ray) techniques. The efficiency of the prepared nanostructure has been explored for the synthesis of benzimidazoles via the condensation reaction of orthoesters and diamines at 60 °C under solvent-free conditions. The successful synthesis of benzoxazole has also been explored through the condensation of orthoesters with 2-aminophenol in water media at room temperature. The recovery and reusability of the nanocatalyst has also been examined via 4 runs without activity loss. Partial short reaction times, high yields of products, mild reaction conditions in the absence of any hazardous solvent, and reusability of the nanocatalyst are noteworthy advantages of this method.

In the present paper, silver nanoparticles (AgNPs) were synthesized using the Brassica oleraceae fruit extract under the simple and eco-friendly conditions. The reaction between silver nitrate, as metal source, and aqueous extract of Brassica oleraceae fruit, as reductant agent, produced AgNPs in high yield. The formation of AgNPs was confirmed by means of UV-Vis spectroscopy and scanning electron microscopy (SEM) was used for characterization of morphology and size of silver nanoparticle products. The investigation of diverse reaction parameters revealed that reductant concentrations, reaction pH, mixing ratio of the reactants and interaction time affected the size and morphology of synthesized AgNPs. AgNPs with 32.74 nm size and amorphous, based on SEM images, were produced within 24 h interaction period. AgNPs also showed a good antibacterial activity against Escherichia coli.

In this paper we report the synthesis and characterization of two new binuclear Cd(II) macrocyclic Schiff base complexes [CdL23pydfp(NO3)], (1), and [CdL33pydfp(NO3)], (2). [1+1] cyclocondensation of L23py = N-(2-pyridylmethyl)-N-(3-aminpropyl)-1,3-diaminoethane and L33py = N-(3-pyridylmethyl)-N-(3-aminpropyl)-1,3-diaminopropane and 2,6-diformyl-4-methylphenol, dfp, in the presence of Cd(NO3)2.4H2O in equimolar ratios gave two new macrocylclic complexes. Resulting complexes were characterized by NMR, IR, mass spectroscopy and elemental analysis. Spectroscopy studying results show in spite the nitrogen and oxygen atoms of macrocyclic ligand with N4O donor set, one nitrate molecule (with two donor oxygen atoms) is coordinated to the Cd(II) center in each complex. So, the cadmium center is seven coordinated.

Fe2V4O13 is prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-diffuse reflectance spectroscopy (UV-DRS), high resolution scanning electron microscopy (HR-SEM) using energy dispersive X-ray spectroscopy (EDX) analysis. The hetero-Fenton catalyst can be used to mineralize Methyl Orange (MO) under UV-A light. The mineralization rate is influenced by hydrogen peroxide (H2O2) concentration, pH, and catalyst loading. The reusability of Fe2V4O13 is analyzed by five successive runs. At the maximum of 95% of degradation is observed in all five cycles. Therefore, the Fe2V4O13 catalyst is found to be reusable. The mineralization is confirmed by chemical oxygen demand (COD) measurements. Mechanism of the heterophoto-Fenton process is also proposed.<br />Keywords: Fe2V4O13; Methyl Orange; wastewater treatment; hetero-Fenton reaction; photocatalysis
