Abstract Multi-layered composite shells are extensively used in many industrial fields since they have superior performance applications. As load-carrying components, buckling failure is one of the most common modes multi-layered shells. Hence, layup design based on optimal factors widely concerned, where lamination parameters commonly representation stiffness. However, formulations laminate st...

Secure Shell (SSH) is a multi-channel security protocol running over the Transmission Control Protocol (TCP), which offers channels for several services over a secured connection, such as remote shells and connection forwarding. In this paper we introduce a method for using SSH over the Stream Control Transmission Protocol (SCTP), a transport protocol supporting multi-homing and multi-streaming...

Here we report on the synthesis and averaged SERS measurements of multi-shell nanomatryoshka SERS tags. By tuning the number of shells or by changing the Raman reporters in different gap layers, their Raman intensities and spectral bands were tunable. These tags show great potential for SERS-based biosensing and bioimaging.

Geometry incommensurability between weakly coupled shells in multi-walled carbon nanotubes is shown to be the origin of unconventional electronic conduction mechanism, power-law scaling of the conductance, and remarkable magnetotransport and low temperature dependent conductivity when the dephasing mechanism is dominated by weak electron-electron coupling.

Common methods for fabrication of polyelectrolyte microcapsules rely on a multi-step process. We propose a single-step approach to generate polyelectrolyte microcapsules with 1-2 μm shells based on polyelectrolyte complexation across a water/oil droplet interface and study the effect of parameters controlling the polyelectrolyte complexation on shell thickness.

PURPOSE The purpose of this paper is to present a new method for representing heterogeneous materials using nested STL shells, based, in particular, on the density distributions of human bones. DESIGN/METHODOLOGY/APPROACH Nested STL shells, called Matryoshka models, are described, based on their namesake Russian nesting dolls. In this approach, polygonal models, such as STL shells, are "stack...

Chitosanases and proteases have received much attention due to their wide range of applications. Four kinds of chitinous materials, squid pens, shrimp heads, demineralized shrimp shells and demineralized crab shells, were used as the sole carbon and nitrogen (C/N) source to produce chitosanases, proteases and α-glucosidase inhibitors (αGI) by four different strains of Paenibacillus. Chitosanase...

Fibers and yarns based on carbon nanotubes (CNT) are emerging as a possible improvement over more traditional high strength carbon fibers used as reinforcement elements in composite materials. This is driven by a desire to translate the exceptional mechanical properties of individual CNT shells to achieve high performance macroscopic fibers and yarns. One of the central limitations in this appr...

the effect of axial deformation of shell particles on the dynamic instability (flutter) of cantilevered cylindrical shells made of functionally graded materials (fgm) under an end axial follower force is addressed. to this end, at first, results for free vibration of fgm cylindrical shells were verified with previous outcomes and they were in very good agreement. then, the effect of axial defor...
