This study was motivated by the desire to develop accurate simulation models for deployment dynamics of future, ultralight deployable structures consisting multiple thin shells packaged elastically, through a combination folding and coiling. The specific problem studied is packaging unconstrained rectangular space frame formed two thin-shell longerons connected transverse rods, called strip. in...
Abstract Several solar system moons harbor subsurface water oceans; extreme internal heating or irradiation can form magma oceans in terrestrial bodies. Tidal forces drive ocean currents, producing tidal that affects the thermal−orbital evolution of these worlds. If outermost layers (ocean and overlying shell) are thin, dynamics be described using thin-shell theory. Previous work assumed shell'...
This paper develops a new solution of gravitational vacuum star in the background charged Kiselev black holes as an exterior manifold. We explore physical features and stability thin-shell gravastars with radial perturbation. The matter thin layer located at greatly affects stable configuration developed structure. assume three different choices distribution such barotropic, generalized Chaplyg...
The tiny gastropod Coelodiscus minutus is superabundant in concretions of the Early Jurassic Posidonia Shale of South Germany which were formed under anoxic or extremely dysoxic conditions. Previous suggestions that C. minutus was a holoplanktonic organism are corroborated based on new evidence from exceptionally well-preserved specimens. The measurements of shell thickness show that the shell ...
The problem of a thin spherical linearly-elastic shell, perfectly bonded to an infinite linearly-elastic medium is considered. A constant axisymmetric stress field is applied at infinity in the matrix, and the displacement and stress fields in the shell and matrix are evaluated by means of harmonic potential functions. In order to examine the stability of this solution, the buckling problem of ...
In this study, we report anomalous size-dependent photoluminescence (PL) intensity variation of PbS quantum dots (QDs) with the formation of a thin CdS shell via a microwave-assisted cation exchange approach. Thin shell formation has been established as an effective strategy for increasing the PL of QDs. Nonetheless, herein we observed an unusual PL decrease in ultrasmall QDs upon shell formati...
