We report that colloid-in-liquid crystal (CLC) gels can be formed via a two-step process that involves spinodal decomposition of a dispersion of colloidal particles in an isotropic phase of mesogens followed by nucleation of nematic domains within the colloidal network defined by the spinodal process. This pathway contrasts to previously reported routes leading to the formation of CLC gels, which have involved entanglement of defects or exclusion of particles from growing nematic domains. The new route provides the basis of simple design rules that enable control of the microstructure and dynamic mechanical properties of the gels.

Crystallization of silicalite-1 from clear synthesis solutions: Effect of template concentration on crystallization rate and crystal size Soydas, B.; Çulfaz Emecen, Pınar Zeynep; Kalıpçılar, Halil; Culfaz, A. (Wiley, 2009-08-01) Synthesis of silicalite-1 powders and membranes from initially clear solutions with different tetrapropylammonium hydroxide or bromide concentrations was studied. While tetrapropylammonium bromide acts only as template, tetrapropylammonium hydroxide provides both the template and hydroxyl ions to the synthesis medium. The effects of template and hydroxyl ion concentration on the product yield, crystallization rate and crystal size were investigated. Pure and highly crystalline silicalite-1 was obtained with...
AM1 treatment of phenylboronic acid esters of glycerol Türker, Burhan Lemi (Elsevier BV, 2004-05-14) Phenylboronic acid esters of glycerol, which involve 1,2- and 1,3-sites of glycerol for esterification followed by complex formation with the remaining -OH group of glycerol have been considered for AM1(RHF) type semiempirical quantum chemical calculations, in vacuum as well as in aqueous medium. All the species were found to be stable and exothermic. The stability order among the various species considered was established. 1,2-type ester in vacuum or aqueous medium was found to be more stable than the resp...
Anisotropic electrical and dispersive optical parameters in InS layered crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2010-02-01) The anisotropy effect on the current transport mechanism and on the dispersive optical parameters of indium monosulfide crystals has been studied by means of electrical conductivity and polarized reflectance measurements along the a-axis and the b-axis, respectively. The temperature-dependent electrical conductivity analysis in the range 10-350 K for the a-axis and in the range 30-350 K for the b-axis revealed the domination of the thermionic emission of charge carriers and the domination of variable range ...
Energy band gap and oscillator parameters of Ga4Se3S single crystals Qasrawi, A. F.; Hasanlı, Nızamı (Elsevier BV, 2007-06-01) The optical properties of the Bridgman method grown Ga4Se3S crystals have been investigated by means of room temperature, transmittance and reflectance spectral analysis. The optical data have revealed an indirect allowed transition band gap of 2.08 eV. The room temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as 21.08 and 3.85 eV, 6.48 a...
Conducting polymers of decanedioic acid bis-(4-pyrrol-1-yl-phenyl) ester Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-15) A dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and decanedioyl dichloride. The electrochemical behavior of this monomer was studied. Polymerization of decanedioic acid bis-(4-pyrrol-1-yi-phenyl) ester (DAPE) was achieved by chemical and constant current electrolyses methods. Copolymerization of DAPE with thiophene was performed by constant potential electrolysis in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB), dichloromethane-TBAFB, solvent-electrolyte couple...
