  • DFT Study of Small Gold Clusters Aun (n=2-13): The Structural, Electronic,
           Thermodynamic and Spectral Properties

    • Authors: Noha Jabr
      Abstract: The structures and relative stabilities of small gold clusters Aun (n=2-13) have been investigated at The B3LYP/ CEP-121G level of density functional theory with exploitation Gaussian09 program. Relative stabilities of these clusters have been analyzed based on the variation of their binding energies (Eb), fragmentation energies (Efrag), ionization energies (VIP), electron affinities (EA), the energy gap (Egap) and IR spectrum with cluster size (n). We note that the gold clusters Aun (n=2, 4, 6, 8, 10, 12) have a special values of Egap, VIP and Efrag, these indicates that these clusters are more stable than their neighbouring clusters. Binding Enthalpy (ΔHb), Entropy (ΔSb) and Gibbs free energy (ΔGb) of Aun clusters were computed at 298.15K.We note that these amounts decrease with increasing cluster size. We calculate IR spectra for gold clusters and compared our results with experimental data and we note that the clusters Aun (n=6, 8, 10, 12) absorbed at lower wave length. Keywords: Gold clusters, Density Functional theory (DFT), Bending energy, Fragmentation energy, Ionization energy, Electron affinity, Energy gap, Enthalpy, Entropy, Gibbs free energy, IR spectrum.

  • Effects of Physical Activation Procedure on the Production Yield, Surface
           Chemistry and Surface Pores of Coconut Shells Based Activated Carbons

    • Authors: John. Bentil, William Kwame Buah
      Abstract: Activated carbons are produced either by physical or chemical activation or both. However, due to different experimental protocols used in preparing and characterising these carbons, it has been difficult in comparing their yields, surface chemistry and pore developments. In this study the effects of physical activation procedure on yields, surface chemistry and surface pore developments of activated carbons prepared by three physical activation procedures using the same protocols were compared. The results of the yields revealed that during the production of activated carbons better yields are obtained when the particle size of the precursor is reduced to the required size of the expected activated carbon prior to carbonisation and activation. The spectra produced by Fourier transmission infrared spectroscopy demonstrated shift in bands and changes in wavelength numbers and absorbance between the raw and the derived activated carbons  during pyrolysis or activation. Comparing the micrographs of the Scanning electron microscope of the derived carbons also showed an irregular and heterogeneous surface morphology with a well-developed porous structure. Keywords: porosity, micrographs, surface area, yield, activation, spectroscopy

  • High Sensitive C-reactive Protein for Prediction of Cardiovascular Risk
           Level in Patients with Metabolic Syndrome in Sulaimania-Iraq

    • Authors: ABDULQADER AZEEZ AL-NAQSHABANDI, MUDHAFER MOHAMMED M. SAEED, HASAN QADER SOFIHUSSEINd, BADRALDIN KARIM HAMAD
      Abstract: Background and objective: Metabolic syndrome is a group of characteristics, which include obesity, high blood pressure, elevated blood sugar levels, and high triglycerides (fat-like substances in the blood). Having a combination of these characteristics increases the risk of developing type 2 diabetes and heart disease. People with central obesity have an increased risk for developing metabolic syndrome, type 2 diabetes, and cardiovascular disease. However, a substantial number of obese individuals have no other cardiovascular risk factors, besides their obesity. C-reactive protein (CRP) is an acute phase protein produced predominantly by hepatocytes under the influence of cytokines such as IL -6 and TNF-α. Determination of hs-CRP was carried out in this study to discriminate between centrally obese people with and without metabolic syndrome. Patients and Methods: One hundred and forty subject with central obesity aged 20-70 years underwent a physical examination and laboratory assays to determine the presence of metabolic syndrome (NCEP ATP III criteria). The subjects were categorized into metabolic syndrome and non -metabolic syndrome group to decide whether CRP has an impact on the development of metabolic syndrome, and further subdivision have made to sub classify them to five sub-groups according to the existence of components of metabolic syndrome. Results: Mean hs-CRP levels were significantly higher in individuals with central obesity with metabolic syndrome (n = 101; 72.1%) compared to individuals with central obesity without metabolic syndrome (3.64 mg/L versus 1.75 mg/L (IQR 1.25-2.24); p < 0.0001). Mean hs-CRP levels increased with increasing number of metabolic syndrome components present. In univariable linear regression analyses, hs-CRP was significantly correlated positively with body mass index, waist circumference, and atherogenic index, while a significant negative correlations was found with HDL-C level. All the obese participants were at risk of cardiovascular events. Conclusions: The degree of central obesity (waist circumference) and BMI seemed to be the main determinant of an increased hs-CRP level. Serum hs-CRP was significantly correlated with the presence of metabolic syndrome; strong relationship between serum hs-CRP and various features of metabolic syndrome. The addition of serum hs-CRP to the present definition of the metabolic syndrome may help to identify patients at high risk for future cardiovascular disease. Keywords: Abdominal obesity, Metabolic syndrome, High sensitive C-reactive protein.

  • The Preparation of Some 1,2,4-Triazole Ester and Benzotriazole Ester
           Derivatives

    • Authors: Joanna Toumani
      Abstract: We have prepared a 1-chloro ester by a reaction between 4-methoxy Benzaldehyde and Benzoyl chloride, and we have checked the Structure of the produced Compound by IR (Infra Red) and then we have studied the reaction of this compound with Benzotriazole and 1H-1,2,4-Triazole to get the following compounds: (1H-benzo[d][1,2,3]triazol-1-yl)(4-methoxyphenyl)methyl benzoate and (4-methoxyphenyl)(1H-1,2,4-triazol-1-yl)methyl benzoate   Then we have purified the produced compounds by re-crystallization, and their  structures have been checked by (1H-NMR ,13C-NMR ) and FT-IR, Triazole derivatives have a variety of biological applications,  therefore the produced compounds should have many important applications. Keywords: Triazole, esterification, chloro esters.

  • Synthesis and Characterization of Silica from Ragi Husk Ash (Finger
           Millet) by a Sol-gel Method

    • Authors: A. Ananthi, D. Geetha, P.S. Ramesh
      Abstract: Silica aerogel, a mesoporous material, was prepared from ragi husk ash by sol–gel method and dried under atmospheric pressure. In this method, ragi  husk ash, which is rich in silica, was extracted with sodium hydroxide solution to produce a sodium silicate solution. This solution was neutralized with acid to form a silica aerogel. The aged gel was washed carefully by de ionized water and ethanol and finally dried under atmospheric air. A temperature of 7000C was found to be optimum ashing temperature with maximum amorphous silica content. From a morphological analysis obtained by SEM and diffraction patterns (XRD), a longitudinal fibrous and amorphous structure was observed for Ragi Husk. FTIR characterization indicated the presence of silanol and siloxane groups. Thermo gravimetric was used to characterize burning behaviour and also to determine the activation energies. This economic technology, as applied to waste material, also provides many benefits to the local agro-industry. Keywords: Ragi husk Ash, Sol- gel method, Amorphous silica, Aerogel
