| In vitro Inhibition Effect of Transition Metal Ions on Succinate-Fumarate
System in ATP Cycle |
| Muhammad Akhyar Farrukh* and Sana Majeed |
| The effects of different reaction parameters such as initial concentration of succinate, ferricyanide, and the influence of metal ions (Zn+2, Ni+2, Cu+2, Cd+2) on the oxidation of succinate were investigated. The kinetics results indicated that the succinate oxidation was significantly inhibited in the presence of metal ions due to formation of partial bonding of metal ions with succinate.

| Synthesis of Silver Nanowires and Other Metal Nanostructures in
Dialkylimidazolium Ionic Liquid |
| Tamil Selvi Selvam and Kai-Ming Chi* |
| Late transition metal nanostructures can be successfully synthesized via decomposition of organometallic precursors in ionic liquid [Omim][PF6]. Silver nanowires can be specifically generated by heating the mixture of (hfac)Ag(PMe3) and 1-hexadecylamine with the mole ratio of 1:10 in [Omim][PF6] at 140oC for 3 h. In the case of Ru, Rh, Ir, Ni, Pd, Pt, and Au, well dispersed nonoparticles or nanoclusters were obtained in the presence of the appropriate surfactants.(Published online: December 4, 2011) |

| The Physical, Chemical and Biological Effects by Room Temperature
Ceramic Far-infrared Ray Emitting Material Irradiated Water: A Pilot Study |
| Ting-Kai Leung,* Jen-Chang Yang and Yung-Sheng Lin |
| We demonstrated that cFIR irradiation reduced the size of water clusters, and significantly increased the freezing temperature of water. We also observed an increase in the volatility of a complex mixture of alcohol, water and solutes and recorded elevated total phenol in green tea infusions prepared using cFIR irradiated water. The possible anti-inflammatory effects of cFIR irradiated water and implications of our study with regard to bone and joint health were discussed. (Published online: November 29, 2011) |

| Investigation of Fatty Acid Composition of Ammi majus Seed Oil by Gas
Chromatography Mass Spectrometry |
| Iqbal Hussain,* Shahid Khan, M. I. Khan, Inayat Ur Rehman and Majed Ahmed |
| The Ammi majus seeds oil constituents of methyl ester derivatives of fatty acids were analyzed using Gas Chromatography coupled to mass spectrometer. The results obtained containing the saturated as well as unsaturated fatty acids of majus seeds oils. A total of 18 different components were identified and quantified. Methyl ester of linoleic acid was found in high concentration 9.00 %, among the identified analytes of interest. In addition methyl ester of Oleic acid 5.60%, Palmitic acid 3.98% Linolenic acids 1.42% were found. Concentration of the rest of identified fatty acids analytes were less than 1%.(Published online: November 28, 2011) |

| Crystal Structure of Lanthanide-oxalate-pyridine-2,4-dicarboxylate
Coordination Polymers Suggesting the Reductive Coupling of Carbon
Dioxide to Oxalate |
| Fwu-Ming Shen and Shie-Fu Lush* |
| Two 2D lanthanide coordination polymers, Nd(III)-oxalate-(2,4-pydc) and Pr(III)-oxalate-(2,4-pydc), by hydrothermal reactions. X-ray structure analyses show that both polymers contain bridging oxaltae (C2O42-) ligands, which might have been formed by the coupling of two CO2-radicals, released from pydc2- ligands. Both compounds show high thermal stability.(Published online: November 23, 2011) |

| Ultrasound Assisted Emulsification Microextraction Based on dimetyl
(E)-2-[(Z)-1-acetyl)-2-hydroxy-1-propenyl]-2-butenedioate for
Determination of Total Amount of Iron in Water and Tea Samples |
| Gholamreza Khayatian* and Shahed Hassanpoor |
| An ultrasound assisted emulsification microextraction (USAEME) is successfully used for extraction and determination of trace amount of iron in water and tea samples, followed by flame atomic absorption spectroscopy (FAAS). The linear range of the method is sufficient for the determination of iron in some environmental samples and was successfully used in the determination of total iron in river waters, tap waters and tea samples.
