Microcrystalline Al-8.5 wt.% Fe-1.06 wt.% V-2.75 wt.% Si, ribbon was produced by a planar flow casting (PFC) technique. Environmental scanning electron microscopy, X-ray diffraction and Mossbauer spectroscopy proved that the polycrystalline alloy consists of a supersaturated Al matrix and quaternary Al-S-Fe-V dispersoids. The observed single exothermal peak in the differential scanning calorimetry curves was ascribed to partial decomposition of the Al supersaturated solid solution. After prolonged heating at 873 K, the microcrystalline alloy still consists of supersaturated Al matrix with lattice parameter 0.40485(4) nm, reinforced by silicide particles with chemical formula Al-13.18(Fe,V)(1.84)Si and lattice parameter 1.2578(8) nm.

A stable carbonyl-pyrazine-metal(0) complex: Synthesis and characterization of cis-tetracarbonylpyrazinetrimethylphosphitetungsten(0)
Alper, Fatma; Kayran, Ceyhan; Özkar, Saim (2006-06-01)
Pentacarbonylpyrazinetungsten(0), (CO)(5)W(pyz), is not stable in solution in polar solvents such as acetone or dichloromethane and undergoes conversion to a bimetallic complex, (CO)(5)W(pyz)W(CO)(5) plus free pyrazine. These three species exist at equilibrium. Using the quantitative H-1 NMR spectroscopy, the equilibrium constant could be determined to be K-eq = (5.9 +/- 0.8) x 10(-2) at 25 degrees C. Introducing a second pyrazine ligand into the molecule does not stabilize the complex, as CiS-W(CO)(4)(pyz)...
Leaf anatomy of Agropyron Gaertn. (Gramineae) in Turkey
Mavi, D. Ozlem; Doğan, Musa; Cabi, Evren (2011-01-01)
Agropyron cristatum (L.) Gaertn. is represented by 2 subspecies in Turkey, namely subsp. incanum (Nabelek) Melderis and subsp. pectinatum (M.Bieb.) Tzvelev. This study examines the taxonomic significance of the leaf properties of the taxa of Agropyron Gaertn., comprising diagnostic anatomical features obtained from leaf transverse sections as well as leaf surface micromorphology. Results of the study show that most of the characters, such as the shape of the leaf blades; the size and number of stomata; the ...
Crosslinking of Trimethylene Carbonate and D,L-Lactide (Co-) Polymers by Gamma Irradiation in the Presence of Pentaerythritol Triacrylate
Bat, Erhan; Feijen, Jan; Grijpma, Dirk W. (Wiley, 2011-07-07)
High-molecular-weight (co) polymers of trimethylene carbonate and D, L-lactide are efficiently crosslinked using PETA during gamma irradiation. Form-stable networks with gel contents of 86 +/- 5 to 96 +/- 1 are obtained from non-crystalline (co) polymers. Glass transition temperatures and elastic moduli of the networks can be varied by adjusting the copolymer composition. The PETA-containing (co) polymer networks are not cytotoxic. Upon incubation in macrophage cultures for 14 d, all (co) polymer films and ...
Crosslinked DADMAC polymers as cationic super absorbents
Korpe, Sinan; Erdogan, Baris; Bayram, Göknur; Özgen, Serkan; Uludağ, Yusuf; Bicak, Niyazi (Elsevier BV, 2009-09-01)
Loosely crosslinked cationic polyelectrolytes (polyquats) with super-water-sorption abilities are presented, for the first time. Hydrogels obtained by radically initiated copolymerization of N,N-diallyl, N,N-dimethyl ammonium chloride (DADMAC) with N-vinyl 2-pyrrolidone (NVP) in presence of N,N,N',N'-tetraallyl piperazinium dichloride (TAP) as crosslinker showed reasonably high equilibrium swelling ratios, as high as those for poly(acrylic acid)-based super absorbents.
Synthesis and characterizations of N,N-bis(diphenylphosphino)ethylaniline derivatives and X-ray crystal structure of palladium (II), platinum (II) complexes
DURAP, FEYYAZ; BİRİCİK, NERMİN; Guemguem, Bahattin; Özkar, Saim; Ang, Wee Han; Fei, Zhaofu; Scopelliti, Rosario (2008-01-20)
N,N-Bis(diphenylphosphino)ethylaniline compounds, [Ph2P](2)N-C6H4-C2H5, with ethyl groups at the ortho- and para-positions have been synthesized. Oxidation of the aminophosphines with hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides [Ph2P(E)](2)N-C6H4-C2H5 (E = O, S, Se). Complexes [MCl2{(Ph2P)(2)N-C6H4-(C2H5)}] (M = Pd, Pt) and [Cu{(Ph2P)(2)N-C6H4-C2H5)(2)]PF6 were obtained by the reaction of NN-bis(diphenylphosphino)ethylaniline with [MCl2(COD)] (M = P...
