Zeolite framework stabilized rhodium(0) nanoclusters; were prepared by a two steps procedure: incorporation of Rh3+ ions into the Zeolite-Y by ion-exchange followed by in situ reduction of Rh3+ ions during the catalytic hydrolysis of ammonia-borane. They are stable enough to be isolated as solid materials and characterized by HRTEM, XPS, XRD, SEM, EDX, and N-2 adsorption. These nanoclusters are isolable, bottleable, redispersible, and reusable as an active catalyst in the hydrolysis of ammonia-borane even at low temperatures. Zeolite framework stabilized rhodium(0) nanoclusters; provide exceptional catalytic activity (TOF = 92 mol H-2/mol Rh min) and unprecedented lifetime (TTON = 47200 mol H-2/mol Rh) in the hydrolysis of ammonia-borane at 25 +/- 0.1 degrees C.

VERTEX PARTITIONING BASED MULTIPLE DESCRIPTION CODING OF 3D DYNAMIC MESHES Bici, M. Oguz; Stefanoski, Nikolce; Akar, Gözde (2009-05-06) In this paper, we propose a Multiple Description Coding (MDC) method for reliable transmission of compressed time consistent 3D dynamic meshes. It trades off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the decoder side. The method is based on partitioning the mesh vertices into two sets and encoding each set independently by a 3D dynamic mesh coder. The encoded independent bitstreams or so-called descriptions are transmitted independently. T...
Multinucleon transfer in Ni-58+Ni-60 and Ni-60+Ni-60 in a stochastic mean-field approach Yilmaz, B.; Ayik, S.; Yılmaz, Osman; Umar, A. S. (2018-09-07) The multinucleon exchange mechanism in Ni-58 + Ni-60 and Ni-60 + Ni-60 collisions is analyzed in the framework of the stochastic mean-field approach. The results of calculations are compared with the time-dependent random-phase approximation (TDRPA) calculations and the recent data of Ni-58 + Ni-60. A good description of the data and a relatively good agreement with the TDRPA calculations are found.
OPTIMUM DESIGN OF DISCRETE TRANSMIT PHASE ONLY BEAMFORMER Demir, Özlem Tuğfe; Tuncer, Temel Engin (2013-09-13) Transmit beamformer design usually results suboptimum bearnformers in multicast scenario. In this paper, discrete phase only beamformer design is considered. The design problem is cast in such a form that the solution is always feasible and optimum beamformer can be found using the branch and cut algorithm. Beamformer phase terms and their interrelations are expressed with a set of cosine vectors which lead to linear set of constraint equations that can be solved with mixed integer linear prograrmning. It i...
Tungsten(VI) oxide supported rhodium nanoparticles: Highly active catalysts in hydrogen generation from ammonia borane Akbayrak, Serdar; Tonbul, Yalcin; Özkar, Saim (2021-04-01) Herein, we report the use of tungsten(VI) oxide (WO3) as support for Rh0 nanoparticles. The resulting Rh0/WO3 nanoparticles are highly active and stable catalysts in H2 generation from the hydrolysis of ammonia borane (AB). We present the results of our investigation on the particle size distribution, catalytic activity and stability of Rh0/WO3 catalysts with 0.5%, 1.0%, 2.0% wt. Rh loadings in the hydrolysis reaction. The results reveal that Rh0/WO3 (0.5% wt. Rh) is very promising catalyst providing a turn...
Static Aeroelastic calculations for a wing under large deformations Atik, Hediye; Baran, Özgür Uğraş; Tüzün, Aydin (2012-01-01) This paper presents a practical workflow on static aeroelastic problems with extreme deflections. The aim of this study is to achieve a fast, yet robust method to calculate the change of the aerodynamic parameters as well as to ensure structural integrity of a wing deforming under aerodynamic loads. To predict static aeroelastic behavior of a high aspect ratio wing, calculations are performed on very fine grids at a relatively large number of flight conditions. Fluid calculations are performed with FLUENT o...
