Polyaniline (PANI)/Au composite hollow spheres were successfully synthesized using polystyrene/sulfonated polystyrene core/shell gel particle templates. The PANI shell thickness and the number of Au nanoparticles decorating the PANI could be controlled effectively by adjusting the experimental conditions. The morphology, composition, and optical properties of the resulting products were charact...

The Air Force Research Laboratory, Space Vehicles Directorate (AFRL/VS), has developed a unique composite Payload Attach Fitting (PAF) shell design. Alliant Techsystems (ATK) and the Boeing Company, Huntington Beach, CA, have developed manufacturing processes and a shell design that incorporates an all-composite forward flange with transverse reinforcement (Z-pinning) at key locations to preven...

Silkworm cocoons are multi-layered composite structures comprised of high strength silk fiber and sericin, and their mechanical properties have been naturally selected to protect pupas during metamorphosis from various types of external attacks. The present study attempts to gain a comprehensive understanding of the mechanical properties of cocoon shell materials from wild silkworm species Anth...

A practical method to assemble rodlike tobacco mosaic virus and bateriophage M13 with polymers was developed, which afforded a 3D core-shell composite with morphological control.

Hollow spheres of MCM-41 mesoporous aluminosilicates, with two small holes on the shell, have been synthesized from a surfactant-aluminosilicate gel composite.

This paper deals with free vibration analysis of continuously graded fiber reinforced (CGFR) truncated conical shell based on third-order shear deformation theory (TSDT), by developing special power-law distributions. The orthotropic (CGFR) truncated conical shell are clamped and simply supported at the both ends. It is assumed to have a smooth variation of fibers volume fraction in the thickne...

Abstract. We formulate a new free-boundary type mathematical model describing the interac4 tion between a shell and a mesh-like structure consisting of thin rods. Composite structures of this 5 type arise in many applications. One example is the interaction between vascular walls treated with 6 vascular devices called stents. The new model embodies two-way coupling between a 2D Naghdi 7 type sh...

Whilst hydrogels and hollow particles both continue to attract much attention in the literature there are few examples of hydrogel composites containing hollow particles. Here, we study composite polyacrylamide (PAAm) hydrogels containing micrometer-sized pH-responsive shell-crosslinked hollow particles (abbreviated as HPXL) based on poly(methylmethacrylate-co-methacrylic acid) functionalised w...

pH-responsive polymer shell chitosan/poly (methacrylic acid) (CS-PMAA) was coated on mesoporous silica nanoparticles (MSN) through the facile in situ polymerization method. The resultant composite microspheres showed a flexible control over shell thickness, surface charges and hydrodynamic size by adjusting the feeding amount of MSN and the molar ratio of [-NH(2)]/MAA. The MSN/CS-PMAA composite...

We demonstrate that Au-silica-poly(N-isopropylacrylamide) (PNIPA) trilayer composite particles with controllable thickness of PNIPA out-layer can be developed via free radical polymerization using Au-silica core-shell particles as seed. The presence of Au-silica particles does not influence of thermosensitivity of PNIPA shell, which exhibits a similar swelling behavior as pure PNIPA microgels. ...
