Metallic spherical dome shells have received much attention in recent years because they have proven to possess highly impressive optical properties. The expected distinctive changes occurring owing to quantum confinement of conduction electrons in these nanoparticles as their thickness is reduced, have not been properly investigated. Here we carry out a detailed analytical derivation of the qu...

We consider and prove the existence of stable, spherical, thin fluid shells in context a Schwarzschild–Rindler-anti-de Sitter (SRAdS) background. identify metric parameter regions that allow stability these for three cases equations state. The case vacuum shell is especially interesting since it remains consistent with past studies by two authors this manuscript, which showed stable spherical d...

Nano-particles consisting of a core surrounded by multiple outer shells (multishell particles) are used as novel functional materials as well as stiffeners/toughners in conventional composites and nanocomposites. In these heterogeneous particles, the mismatch of thermal expansion coefficients and lattice constants between neighboring shells induces stress/strain fields in the core and shells, w...

Introduction 3D magnetization-prepared fast gradient echo MR sequences, such as MP-RAGE [1], have been widely used for 3D brain volumetric imaging due to high spatial resolution and good contrast between white matter and gray matter. However, these techniques usually require long acquisition time, which increases the probability of motion and decreases clinical throughput. There have been sever...

We explore the effect of precisely defined geometric imperfections on the buckling load of spherical shells under external pressure loading, using finite element analysis that was previously validated through precision experiments. Our numerical simulations focus on the limit of large amplitude defects and reveal a lower bound that depends solely on the shell radius to thickness ratio and the a...

Convection driven by thermal buoyancy in rotating spherical bodies of fluid has long been recognized as a fundamental process in the understanding of the properties of planets and stars. Since these objects are rotating in general and since their evolution is associated with the transport of heat from their interiors convection influenced by the Coriolis force does indeed play a dominant role i...
