The spectral, structral and thermal characterizations of dimethyl sulphoxide, pyridine, ethanolamine and N-methyl formamide intercalated kaolinites
Çağlar, Bülent; Afşin, Beytullah; Eren, Erdal; Tabak, Ahmet; Çırak, Çağrı; Çubuk, Osman (Verlag der Zeitschrift fur Naturforschung, 2010)The intercalation of dimethyl sulphoxide (DMSO), pyridine (Py), ethanolamine (Ea), and Nmethyl formamide (NMF) molecules into the kaolinite interlayers led to an appreciable decrease of 3697 cm-1 of the hydroxyl band. The ... -
Structural analysis of naproxen-intercalated bentonite (Unye)
Tabak, Ahmet; Yılmaz, N.; Eren, E.; Caglar, B.; Afsin, B.; Sarihan, A. (Elsevier, 2011)The difference in the basal spacing (8.79Å) and a higher mass loss (6.2%) in the temperature range of 200-750°C of naproxen-bentonite (N-bentonite) comparing to that of Unye bentonite (UB) signified the existence of thermally ... -
Structural analysis of reactive dye species retained by the basic alumina surface
Tabak, Ahmet (Springer, 2009)The alumina-dye composites were prepared by treating the basic alumina with the water solutions of Reactive Red 120 (RR 120) and Reactive Blue 15 (RB 15) dyes. The bands of low intensities in the 1400-1600 cm-1 region and ... -
Structural characterization of aniline-bentonite composite by FTIR, DTA/TG, and PXRD analyses and BET measurement
Köksal, E.; Afşin, B.; Tabak, Ahmet; Çağlar, B. (Taylor & Francis, 2011)The aniline species incorporated into the acid-activated bentonite matrices leads to the decay of the skeletal stretches centered at 1041 cm-1 and the rise of new features in the phenyl ring frequency region, 1700-1400 ... -
Structural characterization of hexadecyltrimethylammonium-smectite composites and their potentiometric electrode applications
Çubuk, Osman; Çağlar, Bülent; Topçu, Cihan; Çoldur, Fatih; Sarp, Gökhan; Tabak, Ahmet; Şahin, Erdal (Elsevier, 2015)Organosmectites were prepared by the intercalation of hexadecyltrimethylammonium cations at various ratios into interlayer of Unye smectite. Structural, thermal, morphological and textural properties of the synthesized ... -
Structural, thermal, morphological and surface charge properties of dodecyltrimethylammonium-smectite composites
Çağlar, Bülent; Topçu, Cihan; Çoldur, Fatih; Sarp, Gökhan; Çağlar, Sema; Tabak, Ahmet; Şahin, Erdal (Elsevier, 2016)The present investigation was undertaken to obtain information about the structural, thermal, morphological, surface charge and textural properties of the synthesized dodecyltrimethylammonium-smectite composites at various ... -
A zinc(II) metal organic framework based on flexible o-phenylenediacetate and rigid 4,4 '-azobis(pyridine) ligands: Synthesis, crystal structure and hydrogen gas adsorption property
Günay, Güneş; Yeşilel, Okan Zafer; Erer, Hakan; Keskin, Seda; Tabak, Ahmet (Pergamon-Elsevier Science Ltd, 2015)A new three-dimensional (3D) metal organic framework, [Zn-2(mu(4)-o-pda)(2)(mu-abpy)](n) (1), has been synthesized by the hydrothermal reaction and characterized by FT-IR spectroscopy, elemental analysis, thermal analysis, ...
