Abstract Producing a consistent layer quality for different raw-materials is challenge powder-based additive manufacturing. Interparticle cohesion plays key role on the powder spreading process. In this work, we characterise structure of deposited layers in powder-base manufacturing process by numerical simulations using discrete element method. The effect particle evaluated. It found that high...
Diatoms are microscopic algae with a skeleton called frustule, formed chiefly of silica, and found in almost all aquatic environments climatic conditions. Diatomaceous soils (DSs) originate from frustule sedimentation. In civil works (design construction), the uncommon values obtained DSs not completely understood. There needs to be more knowledge about strength compressibility DSs. The stabili...
the aim of this study was to find any structural differences between the digital pads of forelimbs and hind limbs as well as more careful investigation of the internal and external structures of the toe-pad. in this study, pad morphology and cytology in litoria caerulea is described using sem, tem and light microscopy. at the gross anatomical level, toe-pads in hind limbs were subdivided into m...
Abstract: In this study, carbon nanotubes (CNTs) were grown directly in the pores of micro porous pyrex membranesand consequently ceramic membranes with very fine pores and high porosity were achieved. Our experiment was donein two stages. Initially cobalt powder with different percent was homogeneously mixed with pyrex powder. In order toproduce row membranes, each of these mixtures were compa...
In this article, we show for the first time, both theoretically and empirically, that plasmonic coupling can be used to generate Localized Surface Plasmon Resonances (LSPRs) in transition metal dimeric nano-antennas (NAs) over a broad spectral range (from the visible to the near infrared) and that the spectral position of the resonance can be controlled through morphological variation of the NA...
