Síntese e caracterização de alfa-fosfato de zircônio(IV) contendo agregados de cobre metálico Synthesis and characterization of alpha-zirconium (IV) hydrogenphosphate containing metallic copper clusters

Química Nova, 2005
The alpha-zirconium (IV) hydrogenphosphate (alpha-ZrP) has received great attention in the last years due to its properties like ion exchange, intercalation, ionic conductivity and catalytic activity. This work reports a method to produce metallic copper

Modelling one-dimensional driven diffusive systems by the Zero-Range Process

, 2004
The recently introduced correspondence between one-dimensional two-species driven models and the Zero-Range Process is extended to study the case where the densities of the two species need not be equal.

Two-point correlation function of an exclusion process with hole-dependent rates

, 2014
We consider an exclusion process on a ring in which a particle hops to an empty neighbouring site with a rate that depends on the number of vacancies $n$ in front of it.

From optimal measurement to efficient quantum algorithms for the hidden subgroup problem over semidirect product groups

, 2005
We approach the hidden subgroup problem by performing the so-called pretty good measurement on hidden subgroup states. For various groups that can be expressed as the semidirect product of an abelian group and a cyclic group, we show that the pretty good

Efficient reduction of nitric oxide using zirconium phosphide powders synthesized by elemental combination method

Scientific Reports, 2017
Zirconium phosphide (ZrP) powders were synthesized by elemental combination method via the direct reaction of zirconium powders with red phosphorus, and characterized by XRD, SEM, XPS, XRF, SAED and TEM measurements.

Properties of poly(lactic acid) nanocomposites based on montmorillonite, sepiolite and zirconium phosphonate

eXPRESS Polymer Letters, 2012
Poly(lactic acid) (PLA) based nanocomposites based on 5 wt.% of an organically modified montmorillonite (CLO), unmodified sepiolite (SEP) and organically modified zirconium phosphonate (ZrP) were obtained by melt blending.

Collective traffic-like movement of ants on a trail: dynamical phases and phase transitions

, 2004
The traffic-like collective movement of ants on a trail can be described by a stochastic cellular automaton model. We have earlier investigated its unusual flow-density relation by using various mean field approximations and computer simulations. In this

Finite-size effects in dynamics of zero-range processes

, 2010
The finite-size effects prominent in zero-range processes exhibiting a condensation transition are studied by using continuous-time Monte Carlo simulations.

SERS property of Co complex on boron nitride nanosheets/silver nanoparticles aggregates and photophysical characterisation of interactions among Co complex ion-exchanged within zirconium phosphate

Journal of Experimental Nanoscience, 2017
The Co(II) complex of [Co(bpy)2(NO3)]Cl·3H2O, bpy = 2,2'-bipyridine, has been synthesised by the solution crystallisation method. The boron nitride nanosheets/silver nanoparticles/[Co(bpy)2(NO3)]Cl·3H2O nanoaggregate was prepared in order to better ...
