  • Methylene Blue Adsorption onto Coconut husks/Polylactide Blended Films:
           Equilibrium and Kinetic Studies

    • Authors: Ali Shee, John Mmari Onyari, John Namakwa Wabomba, Daniel Munga
      Abstract: The removal of cationic methylene blue (MB) from aqueous solutions by coconut husks/polylactide blended films was studied in a batch system. Experiments were modeled as a function of contact time, initial dye concentration, ionic strength, adsorbent dose, temperature and initial solution pH. Equilibrium data fitted the Langmuir isotherm model (R2>0.9866) with monolayer adsorption capacity qm = 16.34mg/g at 296K. Adsorption kinetics followed the pseudo-second model (R2>0.9997) hence chemisorption rate limiting step was dominant. The results have shown viability of coconut husks/polylactide blended films for the removal of recalcitrant MB from both domestic and industrial wastewaters. Key words: coconut husks, polylactide, methylene blue, isotherm, kinetics

  • Investigation into the Behaviour of Polymer-Aggregate Concrete under
           Compressive Loading Condition

    • Authors: Bello; T, Quadri, H.A, Akanbi, D.O., Adeyemi, O.A.
      Abstract: The problem of Housing deficit has been a major problem in Nigeria owing to the perennial hike in prices of building materials in which cement, sand and granite form the nucleus of the materials in the built industry; hence the need to research into local available materials that could replace the conventional materials used in concrete production. This paper investigated the behaviour of a polymer concretes using Reprocessed Pure Water Sachet (PWS) as binder, laterite and clay as aggregates in separate mixtures with polymer for possible replacement of conventional cement concrete in some areas of application. The polymer aggregate concretes were prepared by mixing Reprocessed PWS with laterite and clay differently in different polymer-aggregate percentage replacements by volume (50%-50%, 60%-40%, 70%-30%, and 80%-20%) after sieve analysis had been carried out on aggregate samples. Compressive strength test was carried out on all samples after 28 days of air drying. It was discovered that polymer aggregate concrete compresses under a small applied load ranging from an average of 1.13KN to 1.88KN; and the loss in weight/height was alarming as the polymer (Reprocessed PWS) content in the concrete mix increases. It was also discovered that, the more the polymer content the lower the compressive strength in both cases, that is, laterite and clay aggregates but higher values were recorded in laterite but still a far cry from average compressive strength of reinforced concrete. The compressive strength ranged from 3.0N/mm2-1.0N/mm2 (50%-50% to 80%-20%) for laterite aggregate and 1.0N/mm2-0.5N/mm2 for clay aggregate. However, it was observed that polymer aggregate concretes behaved in such a manner that, under compression process, the samples didn’t break as always in the case of conventional cement concrete but a loss in weight and height were recorded owing to solvent oozing out of samples under compression process. Keywords: Polymer Concrete (PC), Pure Water Sachet (PWS), Polymer-Aggregate, Sieve analysis, Compressive Strength.

  • Grafting of Maleic Anhydride onto Cyclized Natural Rubber by Reactive
           Processing: the Effect of Maleic Anhydride Concentrations

    • Authors: M. Said Siregar, Thamrin ., Basuki WS., Eddiyanto ., J.A. Mendez
      Abstract: Grafting of Maleic Anhydride onto Cyclized Natural Rubber has been performed in the Internal Mixer at 150oC and 80 rpm. The grafted product were analysed by Fourier Transformed Infra Red to determine the presence of Maleic Anhydride onto Cyclized Natural Rubber and Differential Scanning Chalorimetry and Thermogravimetric Analysis to investigated their thermal properties. Fourier Transformed Infra Red spectra confirmed that the grafted product accured by appearance of characteristic band at 1720 cm-1. The higher concentration of Maleic Anhydride reacted the higher of grafting degree of Maleic Anhydride by means of carbonyl index. Futhermore, the glass transition temperature values increase with increasing the grafting degree of Maleic Anhydride and Thermogravimetric Analysis thermogram showed the thermal properties of grafted product did not change significantly compared with the Cyclized Natural Rubber blank. Keywords: grafting, cyclized natural rubber, reactive processing, maleic anhydride

  • Suzuki-Miyaura Cross-Coupling Reaction Based on Novel Palladium(II)
           Diphenylphosphine Derivative Catalyst

    • Authors: Albara I. Al-Rawashdeh, Khalid H. Abu-Shandi, Aiman E. Al-Rawajfeh, Asma M. Al-Dawdeyah, Rasheed M. A. Q. Jamhour, Ghassab M. Al-Mazaideh, Mazen R. Garaleh, Zeinab I. Etiwi, Taghreed M. A. Jazzazi, Tareq M. Al Shboul
      Abstract: The synthesis and characterization of palladium complexes ((CH3)3SiC6H4PPh2)2PdCl2,4a, and ((CH3)3SiC12H8PPh2)2PdCl2, 4b, containing phosphine (CH3)3SiC6H4PPh2, 3a and (CH3)3SiC12H8PPh2,  3b ligands are reported. The phosphine ligands are prepared conveniently in high yield by treatment of the corresponding 1,4-dibromoarene  with one equivalent of butyl lithium, and one equivalent of ClPPh2 at -78 °C under an atmosphere of argon. The palladium complexes are synthesized by the reaction of Pd(cod)Cl2 with two equivalent of the above mentioned phosphine ligands. The new complexes were fully characterized by spectroscopic methods  and elemental analysis. Furthermore, the use of the palladium (II) complexes of such system as pre-catalysts for the Suzuki-Miyaura coupling of some arylbromides and arylchloride with substituted  phenyl boronic acid has been tested. Keywords:1,4-dibromoarene, Palladium complex, Suzuki coupling, catalyst.

  • Antifungal Activities of Curry Leaf (Murraya Koengii) Extract on Some
           Selected Fungi

    • Authors: Gabriel Charles Disegha, Vincent Onuegbu Izionworu
      Abstract: Studies on the antifungal activity of aqueous and organic extracts of Murraya koeingii (curry leaf) on fungi was undertaken using Candida albicans, Penicillium funiculosum, Penicillium camemberti, Aspergillus niger as test organisms. Aqueous and organic extracts of the plants were obtained using standard techniques. The extracts were Cold aqueous extract (CAE), hot aqueous extract (HAE) and Ethanol extract (EE). Sensitivity test was carried out using Agar Well Diffusion Method; the set up was incubated at 370c for 24 hours. Development of zones of inhibition was observed and measured. This showed that some of the tested extracts demonstrated antifungal activities against the test organisms. Comparison of the extracts showed that Ethanol aqueous extract (EE) of Murraya koengii had high activity against all test organisms. The Minimum Inhibitory Concentration of Cold, Hot and Ethanol extracts of Murraya koenigii was 20g/ml for all the test organisms.Since the Cold and Hot extracts did not demonstrate high activity on the test organism, it could be concluded that the activity demonstrated by both Cold and Hot aqueous extract was due to the effect of the extracts. These results indicate that Murraya koengii can be used as an antifungal agent in the treatment of infections. Keywords: antifungal, fungi, murraya koeingii (curry leaf), organisms, organic extract
