Photoactivatable gold NPs were patterned via photolithography. In this approach, charge reversal of the ligands on NPs upon UV irradiation induces crosslinking to generate stable NP patterns.


Carbon supported and surfactant stabilized metal nanoparticle catalysts for direct methanol fuel cells
Çelik, Çağlar; Gökağaç Arslan, Gülsün; Department of Chemistry (2005)
Carbon supported surfactant, such as 1-decanethiol and octadecanethiol, stabilized platinum and platinum/ruthenium species have been prepared recently. In this thesis, for the first time, 1-hexanethiol has been used as an organic stabilizer for the preparation of carbon supported platinum and platinum/ruthenium nanoparticle catalysts. These new catalysts were employed for methanol oxidation reaction, which were used for direct methanol fuel cells. Cyclic voltammetry, X-ray photoelectron spectroscopy and tra...
Facile synthesis of poly(hydridocarbyne): A precursor to diamond and diamond-like ceramics
Nur, Yusuf; Pitcher, Michael W.; Seyyidoglu, Semih; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01)
Polycarbynes have previously been shown to be polymeric precursors to diamond and diamond-like carbon. Here, we report an incredibly simple method for producing one of these polymers, poly(hydridocarbyne). The method simply requires chloroform, electricity, a solvent and an electrolyte. Since the polymer is soluble, the production of diamond objects of any shape is feasible. It is hoped that the ease of the synthesis will make these types of polymers accessible to scientists from all disciplines and that th...

In the present work carboxymethylcellulose (CMC) and CMC-gelatin were used as carrier systems for urease immobilization. Immobilization was based on the formation of insoluble salts of CMC and gelatin with chromium(111) ions. Chromium(111) acetate (CA) and chromium(111) sulfate (CS) were used for this purpose and their effect on urease activity was investigated. The activities of immobilized urease using pure and CMC-gelatin carrier systems were compared. Urease activity was determined by using Berthelot me...
Nano structural metal nano composites: synthesis, structural and thermal characterization
Orhan, Tuğba; Kayran, H. Ceyhan; Department of Chemistry (2009)
Recently, the use of block copolymers in preparation of nanocomposites has received great attention as they form well-defined micelles. In this work, the synthesis of different metal functional copolymers, nano structural metal composites and investigation of their reaction mechanism and thermal characteristics by pyrolysis mass spectroscopy have been aimed. Namely, polyisoprene-block-poly2vinylpyridine, (PI-b-P2VP) and poly2vinylpyridine-block-polymetylmethacrylate, (PMMA-b-P2VP) were used as block copolym...
Power conversion efficiency enhancement of organic solar cells by addition of gold nanostars, nanorods, and nanospheres
Kozanoglu, Duygu; Apaydın, Dogukan Hazar; Çırpan, Ali; Nalbant Esentürk, Emren (Elsevier BV, 2013-07-01)
The effects of gold (Au) nanoparticles (NPs) with different morphologies (star, rod, sphere) incorporated into buffer layer, poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS), of polymer-based organic solar cells (OSCs) were investigated. Solar cells having gold nanoparticles exhibited significant improvement in device efficiency relative to the reference device. The observed improvement is most likely due to the surface plasmon and enhanced light reflection and scattering properties of ...
