To discuss the potential role of the support for iridium catalyst, we have proceeded to prepare a series of supported catalysts with the same active phase content, but different silica content, to elucidate the changes in surface structure and the reaction process of hydrous hydrazine decomposition on catalyst. The obtained iridium catalysts contained 20 wt% of nanoparticles dispersed on spheri...

The dominant mechanism affecting the flow behavior of granular materials is the random motions of particles resulted from the interactive collisions between particles. The velocity fluctuations induce the segregation in granular flows. The different physical properties of granular material were used to investigate the segregation in a vibrated granular bed in this paper. The image processing te...

In this paper, we present the exact solution of the Riemann problem for the nonlinear one-dimensional so-called shallow-water or Saint-Venant equations with friction proposed by SAVAGE and HUTTER to describe debris avalanches. This model is based on the depth-averaged thin layer approximation of granular flows over sloping beds and takes into account a Coulomb type friction law with a constant ...

Coulomb effects in granular materials at not very low temperatures. Abstract We consider effects of Coulomb interaction in a granular normal metal at not very low temperatures suppressing weak localization effects. In this limit calculations with the initial electron Hamiltonian are reduced to integrations over a phase variable with an effective action, which can be considered as a bosonization...

We present experimental evidence for a strong analogy between quasi-2D uniform non-equilibrium steady states (NESS) of excited granular materials and equilibrium thermodynamics. Under isochoric conditions we find that the structure of granular NESS, as measured by the radial distribution function, the bond order parameter, and the distribution of Voronoi cells, is the same as that found in equi...

Granular flow in a rotating drum is studied by experiments and by Computation Fluid Dynamics (CFD) simulations. The particulate phase is modelled based on the Continuum Eulerian Approach (CEA) in the simulation. The particulate phase CEA prediction using the common Gidaspow granular kinetic viscosity or the Syamlal-O’brien granular kinetic viscosity fails to predict the measured dynamic angle o...

Vital areas in Bioinformatics research is one of the Protein sequence analysis. Protein sequence motifs are determining the structure, function, and activities of the particular protein. The main objective of this paper is to obtain protein sequence motifs which are universally conserved across protein family boundaries. In this research, the input dataset is extremely large. Hence, an efficien...

The detail structure of the wave function is analyzed at various refinement levels using the methods of wavelet analysis. The eigenvalue problem of a model system is solved in granular Hilbert spaces, and the trajectory of the eigenstates is traced in terms of the resolution. An adaptive method is developed for identifying the fine structure localization regions, where further refinement of the...
