The modular catalysts were fabricated via the combination of the Ni-MgO-Al2O3 mixed oxide nanoplates and the mesoporous SiO2 coating. Due to the dual confinements, the catalysts show high catalytic activity with enhanced coke- and sintering-resistance in the dry reforming of methane reaction.

One-, two- and three-dimensional nanostructures of copper molybdenum oxide hydroxide were successfully constructed by a simple approach through a pH-dependent dimensional transformation of ammonium copper molybdate. Thin nanoplates of copper molybdate, which were obtained by sintering the two-dimensional nanobelts of copper molybdenum oxide hydroxide, exhibited remarkably high reversible lithiu...

Two new antimony telluride single source precursors (SSPs), Ph2SbTeR (R = Et, Ph), have been used to synthesise pure and defect free hexagonal Sb2Te3 nanoplates by thermal decomposition in an organic solvent. The chemical composition of the SSPs plays an important role in the formation of antimony telluride nanocrystals.

In the modern literature, there are practically no data on electrical characteristics of bituminous binders modified with carbon nanotubes and graphene nanoplates, while they necessary for design development innovative asphalt pavement compositions sensitive to super-high-frequency microwave radiation. Contemporary multi-component systems that may contain polymers, rubbers, synthetic or natural...

in this study, the stability problem of a circular orthotropic cylindrical shell under the effect of anaxial compression varying with a power function of time is considered. at first, the modified donnell typedynamic stability and compatibility equations are obtained using love’s shell theory. applying the galerkinmethod and rayleigh-ritz variational techniques to these equations and taking the...

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

Finite element meshes and nodenumberings suitable for parallel solution with equally loaded processors are presented for linear orthotropic elliptic partial differential equations. These problems are of great importance for instance in oil and airfoil industry. The linear systems of equations are solved by the conjugate gradient method preconditioned by modified incomplete factorization, MIC. T...

The goal of this contribution is the development of a plane stress orthotropic plasticity material model for clear spruce wood. Such a model has to consider an initially linear elastic domain as well as hardening and softening behaviour at higher states of stress and strain, respectively. Combining the advantage of a smooth single-surface plasticity model with the identification of distinct har...

This paper describes a new NMR imaging modality--MR diffusion tensor imaging. It consists of estimating an effective diffusion tensor, Deff, within a voxel, and then displaying useful quantities derived from it. We show how the phenomenon of anisotropic diffusion of water (or metabolites) in anisotropic tissues, measured noninvasively by these NMR methods, is exploited to determine fiber tract ...
