Addressed herein is a novel, eco-friendly, recoverable, reusable and bottleable catalytic system developed for the dihydroxylation of various olefins yielding 1,2-cis-diols. In our protocol, zeolite-confined osmium (0) nanoclusters (zeolite-Os-0) are used as reusable catalyst and H2O2 served as a co-oxidant. Zeolite-Os-0 are found to be highly efficient and selective catalysts for the dihydroxylation of a wide range olefins in an aqueous acetone mixture at room temperature. In all of the olefins surveyed, the catalytic dihydroxylation reaction proceeds smoothly and the corresponding 1,2-cis-diols are obtained in excellent chemical yield under the optimized conditions. The present heterogeneous catalyst system provides many advantages, such as being eco-friendly and industrially applicable over the traditional homogenous OsO4-NMO system for the dihydroxylation of olefins.

Numerical Implementation of Equivalence Principle Algorithm for Potentials Farshkaran, Ali; Ergül, Özgür Salih (2018-07-13) We present a novel implementation of the equivalence principle algorithm (EPA) applied to the recently developed potential integral equations (PIEs) for low-frequency problems involving perfect electric conductors. The equivalence integral equations are generalized and updated by including potentials, making it possible to use PIEs to formulate inner problems. The stability of the implementation is demonstrated on canonical objects.
Graphene oxide/magnesium oxide nanocomposite: A novel catalyst for ozonation of phenol from wastewater Heidarizad, Mahdi; Şengör, Sema Sevinç (2017-01-01) Catalytic ozonation is a promising advanced oxidation technique for the removal of contaminants from water and wastewater. Graphene oxide (GO) is an oxidized derivative of graphene which contains epoxide, hydroxyl, and carboxyl groups with high surface area, and is being recently used for effective adsorption of pollutants in aquatic environments. In our previous work, we modified GO with magnesium oxide (MgO) and demonstrated the high-rate adsorption of methylene blue (MB) by the synthesized nanocomposite ...
Dihydrogen Phosphate Stabilized Ruthenium(0) Nanoparticles: Efficient Nanocatalyst for The Hydrolysis of Ammonia-Borane at Room Temperature DURAP, FEYYAZ; Caliskan, Salim; Özkar, Saim; Karakas, Kadir; Zahmakıran, Mehmet (2015-07-01) Intensive efforts have been devoted to the development of new materials for safe and efficient hydrogen storage. Among them, ammonia-borane appears to be a promising candidate due to its high gravimetric hydrogen storage capacity. Ammonia-borane can release hydrogen on hydrolysis in aqueous solution under mild conditions in the presence of a suitable catalyst. Herein, we report the synthesis of ruthenium(0) nanoparticles stabilized by dihydrogenphosphate anions with an average particle size of 2.9 +/- 0.9 n...
Palladium nanoparticles supported on cobalt(II,III) oxide nanocatalyst: High reusability and outstanding catalytic activity in hydrolytic dehydrogenation of ammonia borane Akbayrak, Serdar; Özkar, Saim (2022-11-01) A new palladium(0) nanocatalyst is developed to enhance the catalytic efficiency of precious metal catalysts in hydrogen generation from the hydrolytic dehydrogenation of ammonia borane. Magnetically separable Pd-0/Co3O4 nanocatalyst can readily be obtained by the reduction of palladium(II) cations impregnated on cobalt(II, III) oxide at room temperature. The obtained Pd-0/Co3O4 nanocatalyst with 0.25% wt. palladium loading has outstanding catalytic activity with a record turnover frequency of 3048 min(-1) ...
Efficiency Optimization of a Direct Torque Controlled Induction Motor used in Hybrid Electric Vehicles Sergaki, Eleftheria S.; Moustaizis, Stavros D. (2011-09-10) The main contribution of this paper is the application of Loss Minimization control algorithm of a three-phase squirrel-cage induction motor which is used in parallel with an internal combustion engine (ICE), in hybrid electric vehicles (HEY). During steady state operation of the electric motor, the electric motor's optimal motor flux profile minimizes the electric motor losses and maximizes the overall HEN efficiency, hybridization factor (HF). During steady state operation of the direct torque controlled ...
