  • Challenges of Educational Development in Nigeria: Issues of Chemical
           Sciences

    • Authors: M. Adejumoke Hashimi
      Abstract: A wealth of research has revealed that scientific skill is crucial for national development and material well-being of any country. While lack of scientific knowledge is often a critical limitation to economic progress, hence, the importance of science in Nigeria Educational system cannot be over emphasized. So there is a need to improve on science subjects/courses in our schools and institutions if the country is to meet the rising expectation of people.This paper, discusses among other things the place of science in Nigeria Educational system as stated in the National Policy of Education. It brings into fore the importance of science programmes in the National development. However, the paper focuses more importantly on chemical sciences, because of the role it plays among the basic sciences, afterall, after God, the power of creation is given to chemists. The paper discusses further the challenges that are facing the effective teaching and learning chemistry in Nigerian schools. At the tail end of the paper it proffers likely solutions. Finally, the paper is ended with suggestions, recommendations and conclusion. It is important that government at all levels should fund education and increase annual budgetary allocation to minimum recommendation of United Nations Educational, scientific and cultural education (UNESCO) which is 26%.

  • Substituents Effect on the Kinetics and Mechanisms of Formation of Copper
           (II) and Nickel (II) Complexes of Some Β-Diketones

    • Authors: ADEAGBO Adewumi I., OLADIPO Mary A., OGUNLUSI; Grace O., ODUNOLA Olusegun A.
      Abstract: Chelates of β – diketones (R1COCH2COR2) with transition metals have been found to possess a wide range of properties and application, some of which are dependent on the substituents (R1 and R2).  Copper(II) and Nickel(II) complexes of β – diketones in which R1= C6H5 and R2 = C6H5 (dbm), R2 = CH3 (bza) R2 = CF3 (tfpbd) and R1 = C4H3S, R2 = CF3(tta) were synthesised and characterised using UV, IR, elemental analysis and magnetic susceptibility. The probable influence of the substituents on the kinetics and mechanisms of formation of the complexes were investigated with the aid of a Thermostated Schimadu 1800 uv-visible spectrophotometer. The reactions were studied at wavelengths characteristics of each complex. Results show the six coordinate copper(II) and nickel(II) complexes have probable distorted octahedral geometry while the four coordinate Ni(dbm)2 is tetrahedral. The kinetics data suggests an influence of the diketonate substituents on the copper(II) and nickel(II) complexes in solution is in the order C6H5 > CH3 >CF3 > C4H3S and CF3 > C6H5 > CH3 > C4H3S respectively. Solvent influence (k-1) was constant in the range 0.007 – 0.008 for fluorosubstituted complexes and least at 0.004 – 0.005 mol-1s-1 in the alkyl substituted complexes. The steady state approximation gave solvent independent rates k1k2 at 25oC, in the copper(II) complexes, k2 is greater than k1 (k2 > k1) , with k2 constant while in the nickel(II) complexes, the values of k2 was less than k1 and ascribed to rate determining and varies with the nickel(II) - ligand systems studied. Keywords: β-diketones, Copper II and Nickel II Complexes, Substituents effect, Kinetics.

  • Synthesis Two Coumarin Derivatives Using Heterogeneous Catalysist

    • Authors: Joumaa Merza
      Abstract: Two coumarin derivatives: 5,7-di Hydroxy-4-Methyl Coumarin (1) and 6-hydroxy-1-methyl-3H-benzo[f]chromen-3-one (2) have been synthesized via Pechmann condensation using Amberlyst-15 as a green catalyst. The coumarin 1 was synthesized by the condensation of phloroglucinol 3 with the ethyl acetoacetate 4, while the coumarin 2 was synthesized from the condensation of β-keto esters 4 with the 1,3-dihydroxy naphthalene 5.The conditions of reactions were as follwing:  (1:1) the molar ration of reagents, (10mol.%, 0.2 g) Amberlyst-15  at 110°C in solvent-free conditions. The yields in this conditions  were (95%) for the compounds 1 and (88%) for the compounds 2. The possibility of recycliny the heterogenus catalyst (amberlyst -15) adds an advantage to the studied reactions. The purified products were  characterized by spectral methods: FT-IR, 1H-NMR , 13C-NMR.

  • Studies on Antioxidant Activities of Papaya (Carica papaya) and Pineapple
           (Ananas cosmosus) Fruits Using Ferric Reducing Antioxidant Power and
           Rancimat Methods

    • Authors: Teshome Degife
      Abstract: Most health-benefits of fruits and vegetables have often been attributed to their antioxidant contents. This paper reports attempts made to look into the antioxidant activities of papaya (Carica papaya) and pineapple (Ananas cosmosus) fruits purchased from fruit shops in Bahir Dar City, North-West Ethiopia, using ferric reducing antioxidant potential (FRAP) and Rancimat methods. The antioxidant activity of the fruits found in the FRAP assay is expressed in terms of μg of ascorbic acid (AA) equivalent per gram of edible flesh part of ripen fresh fruit while that found in the Rancimat method is expressed in terms of protection factor. The FRAP value of papaya fruit (13.6 μg AA/g sample) was found to be higher than that of pineapple fruit (8.6 μg/g AA /g sample). Similarly the protection factor of papaya (1.103) was found to be greater than that of pineapple fruit (1.036). In both the assays employed, it is seen that both papaya and pineapple fruits do exhibit antioxidant properties with the former showing greater reducing power. Keywords: Antioxidants, Antioxidant capacity, Oxidative stress, Ferric-ion reducing antioxidant power, Rancimat method

  • Preparation of Silica Aerogel and Study Its Performance for Adsorption of
           Iron Ions from Aqueous Solution

    • Authors: Rouz Barjoud
      Abstract: Silica aerogel was prepared from cheap waterglass precursors via surface modification of wet gels, ambient pressure drying (APD) route and calcination treatment. Xerogel was also synthesized as a comparison to test the influence of microstructure on the adsorption behaviors. (Ethanol (EtOH)/chlorotrimethylsilane (TMCS)/hexane) solution was employed to replace the surface silanol groups (Si-OH) with alkyl, and to prevent the condensation and shrinkage of the gel structure during the (APD) process. The synthesized silica aerogels, characterized by using Fourier transform infrared spectra (FT-IR), nitrogen adsorption/desorption measurement, etc., are porous solids with surface area (879 m2/g). The transition temperature from hydrophobic to hydrophilic was tested around 395◦C, which corresponds to the disappearance temperature of the -CH3 peaks in FT-IR.These samples were used as absorbent for iron ions. The value of the absorbed percentage in silica aerogel after 4 hours was very close to the value of the absorption percentage after 24 hours, while in silica xerogel the adsorption process continued after 4 hours to be very close to the value of the absorption percentage which was obtained after 4 hours in silica aerogel. Keywords: Xerogel, Aerogel, Silicon oxide, Sol-gel, Silica gel.

  • Synthesis and Spectral Study of 2-furaldehyde Thiourea Ligand and Their
           Complexes with Some Transition Metal (II)

    • Authors: Abeer al Sous
      Abstract: The synthesis and characterisation of Ni(II), Cu(II) of 2-furaldehyde thiourea (FAT) are reported. Elemental analysis, molar conductance and spectral (IR, UV and 1H NMR) measurements have been used to characterise the complexes. In addition, the structure of the complex [Cu(FAT)2]CL2 has been determined by X-ray diffraction methods. In Cu(II) and Ni(II) complexes, the metal ion is coordinated through the sulfur atom and the azomethine nitrogen atom . Keywords: thiourea, Furfural, 2-furaldehyde thiourea; metal complexes,.
