Theoretical research has numerous challenges, particularly about modeling structures, unlike experimental analysis, which explores the mechanical behavior of complex structures. Therefore, this study suggests a new model for functionally graded shell structures called “Tri-coated FGM” using spatial variation material properties to investigate free vibration response incorporating porosities and...

The significance of supported metal catalysts in heterogeneous catalysis calls for in-depth understanding particle sintering behaviour order to rationalize the design stable nanocatalysts. Here, we show that nanoparticles (NPs), exemplified by studying carbon Pt NPs, becomes markedly accelerated when inter-particle distance between neighbouring NPs is shortened. with close proximity are prone f...

We report a general method for the synthesis of hollow structures of a variety of functional inorganics by partial sintering of mesoporous nanocrystal aggregates. The formation of a thin shell initiates the transport of mass from the interior leading to growth of the shell. The principles are general and the hollow structures thus produced are attractive for many applications including catalysi...

We examine the effect of an embedding medium refractive index on the plasmon resonant properties of silica core-gold shell nanoshells. The plasmon response is shifted to longer wavelengths with increasing refractive index of the dielectric host matrix, increasing in overall amplitude for nanoparticles in the dipole limit. For nanoshells of constant core-shell ratio, this plasmon shift increases...

OBJECTIVES Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. MATERIALS AND METHODS Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were su...
