Uniformly distributed single- and double-sided zinc oxide (ZnO) nanocomb structures have been prepared by a vapor-liquid-solid technique from a mixture of ZnO nanoparticles and graphene nanoplatelets. The ZnO seed nanoparticles were synthesized via a simple precipitation method. The structure of the ZnO nanocombs could easily be controlled by tuning the carrier-gas flow rate during growth. Higher flow rate resulted in the formation of uniformly-distributed single-sided comb structures with nanonail-shaped teeth, as a result of the self-catalysis effect of the catalytically active Zn-terminated polar (0001) surface. Lower gas flow rate was favorable for production of double-sided comb structures with the two sets of teeth at an angle of similar to 110 degrees to each other along the comb ribbon, which was attributed to the formation of a bicrystal nanocomb ribbon. The formation of such a double-sided structure with nanonail-shaped teeth has not previously been reported.

We have investigated the energetics and the structural stability of gallium microclusters including 3–7 atoms. A molecular-dynamics technique is employed in the simulation. The potential energy function used in the calculations includes two- and three-body interactions which are represented by Lennard-Jones and Axilrod-Teller type functions, respectively. It was found that the planar configurations are energetically more favorable for all the clusters studied.
Synthesis and characterization of novel rare earth phosphates and rietveld structural analysis of rare earth orthoborates
Seyyidoğlu, Semih; Yılmaz, Ayşen; Department of Chemistry (2009)
This thesis covers the synthesis and the characterization of sodium lanthanide oxide phosphates, rare earth added strontium pyrophosphates and the Rietveld structural analysis of rare earth orthoborates. Solid state and microwave-assisted synthesis method was employed for the synthesis of desired materials. The formation of the produced phases was confirmed by X-ray Diffraction (XRD), Infrared FT-IR, Raman, Scanning Electron Microscopy (SEM) methods. By using Rietveld Refinement method, structural analysis ...
Synthesis of conducting polysiloxane-polypyrrole graft copolymers
Gunaydin, O; Toppare, Levent Kamil; Yagci, Y; Harabagiu, V; Pintela, M; Simionescu, BC (Springer Science and Business Media LLC, 2002-02-01)
Polysiloxane-polypyrrole graft copolymers have been synthesized by a series of chemical reactions and subsequent electropolymerization. First, the hydrosilation of 4-vinyl aniline by dimethyl-methylhydrosiloxane copolymer gave the corresponding aminophenyl functional polydimethylsiloxane (PDMS-NH2). The side chain pyrrole functionalized. polysiloxanes were then prepared by the reaction of PDMS-NH2 with glycidylpyrrole. Finally, the synthesis of graft copolymers of polysiloxane and pyrrole has been achieved ...
Influence of ultrasonically assisted synthesis on particle size of magnetic nanoparticles
KÜÇÜK, Burcu; Özkan, Necati; Volkan, Mürvet (2013-10-01)
Poly(methacrylic acid)(PMAA) coated magnetite (Fe3O4) nanoparticles were synthesized via co-precipitation in aqueous solution with the use of conventional magnetic stirring and ultrasonic agitation. It has been shown that the ultrasonic agitation during the synthesis of magnetite particles decreased the size of PMAA-coated magnetic agglomerates significantly. The primary particle size of iron oxide particles was determined as approximately 10 nm by X-ray diffraction method (Scherer's equation). The volume w...
Synthesis of a regular polymer containing pseudo-polyether cages
Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2005-04-20)
A new compound consisting of 2-thienyl units linked by polyether bridge has been synthesized and its electrochemical polymerization was performed via constant potential electrolysis (CPE) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in CH3CN. Chemical polymerization was carried out using FeCl3 as oxidizing agent. It is found that both methods gave the same polymer product without any cleavage of the polyether bridge between thiophene (Th) rings. Al...
