A new type of supported rhodium nanoparticles were reproducibly prepared from N(2)H(4)BH(3) reduction of [Rh(mu-Cl)(1,5-cod)](2) without using any solid support and pre-treatment technique. Their characterization shows the formation of well dispersed rhodium(0) nanoparticles within the framework of a polyaminoborane based polymeric support. These new rhodium(0) nanoparticles were found to be the most active supported catalyst in the catalytic dehydrogenation of ammonia-borane in water at room temperature.

A moment technique for adsorption rate on metal surfaces of supported catalysts CO adsorption on Pt-Al2O3 washcoated monolith Dogu, G; Ozkan, G; Doğu, Timur (2001-12-15) A moment technique was developed for the investigation of adsorption on metal surfaces of supported catalysts. The technique was applied to the evaluation of adsorption rate parameters of CO on a Pt-Al2O3 washcoated monolith. The adsorption rate constants evaluated in the temperature range 273-316 K showed significant decrease with an increase in surface coverage. Results of pulse response experiments corresponding to zero coverage gave the apparent activation energy for adsorption as 21 kJ/mol. This method...
The preparation and characterization of gold(0) nanoclusters stabilized by zeolite framework: Highly active, selective and reusable catalyst in aerobic oxidation of benzyl alcohol Zahmakiran, Mehmet; Özkar, Saim (2010-05-15) Zeolite framework stabilized gold(0) nanoclusters were prepared by the ion-exchange/impregnation of Au3+ ions with zeolite-Y followed by reduction of the Au3+ ions using sodium borohydride in aqueous solution, all at 50 degrees C. The zeolite framework stabilized gold(0) nanoclusters were isolated as red powder and characterized by HR-TEM, TEM, TEM-EDX, XRD, XPS, DR-UV-vis, SEM, ICP-OES spectroscopic methods and N-2-adsorption technique. This new material was found to be highly active, selective and reusabl...
A parylene coating based room temperature wafer-level attachment method for MEMS integration with zero applied force Beker, Levent; Zorlu, Ozge; Külah, Haluk (2014-08-15) This paper reports a wafer-level attachment method using parylene as an interlayer material for integrating various shaped and fragile substrates into MEMS processes. In the proposed method, the substrates are placed on a handle wafer containing pillars and perforations, and coated with a standard parylene deposition process realized at room temperature, with no applied force. The substrate and the handle wafer are attached to each other via formation of a parylene interlayer. Only poor attachment is observ...
An amperometric acetylcholine biosensor based on a conducting polymer Kanik, Fulya Ekiz; Kolb, Marit; TİMUR, SUNA; Bahadir, Muefit; Toppare, Levent Kamil (Elsevier BV, 2013-08-01) An amperometric acetylcholine biosensor was prepared by the generation of the conducting polymer poly(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine) (poly(SNS-NH2)) on graphite electrodes. For pesticide detection, the enzymes acetylcholinesterase (AChE) and choline oxidase (ChO) were co-immobilized onto the conducting polymer poly(SNS-NH2) films using covalent binding technique. Electrochemical polymerization was carried out using a three-electrode cell configuration via cyclic voltammetry. Characteri...
A Novel Amperometric Glutamate Biosensor Based on Glutamate Oxidase Adsorbed on Silicalite Soldatkina, O. V.; Soldatkin, O. O.; Kasap, B. Ozansoy; Kucherenko, D. Yu.; Kucherenko, I. S.; Akata Kurç, Burcu; Dzyadevych, S. V. (2017-04-07) In this work, we developed a new amperometric biosensor for glutamate detection using a typical method of glutamate oxidase (GlOx) immobilization via adsorption on silicalite particles. The disc platinum electrode (d = 0.4 mm) was used as the amperometric sensor. The procedure of biosensor preparation was optimized. The main parameters of modifying amperometric transducers with a silicalite layer were determined along with the procedure of GlOx adsorption on this layer. The biosensors based on GlOx adsorbed...
