Journal ArticleDOI
Stacking of conical molecules with a fullerene apex into polar columns in crystals and liquid crystals
TL;DR: This work shows that the attachment of five aromatic groups to one pentagon of a C60 fullerene molecule yields deeply conical molecules that stack into polar columnar assemblies, which should be applicable to other molecules and yield a range of new polar liquid crystalline materials.
Journal ArticleDOI
The dynamics of big mantle wedge, magma factory, and metamorphic–metasomatic factory in subduction zones
Shigenori Maruyama,Akira Hasegawa,M. Santosh,Tetsu Kogiso,Soichi Omori,Hitomi Nakamura,Kenji Kawai,Dapeng Zhao +7 more
TL;DR: In this article, the authors classified the upper mantle in this region into three major domains: (a) metasomatic-metamorphic factory (MMF), subduction zone magma factory (SZMF), and the big mantle wedge (BMW).
Journal ArticleDOI
Complete synthetic seismograms up to 2 Hz for transversely isotropic spherically symmetric media
TL;DR: In this article, the direct solution method (DSM) with optimally accurate numerical operators was used to calculate complete (including both body and surface waves) three-component synthetic seismograms for transversely isotropic (TI), spherically symmetric media, up to 2 Hz.
Journal ArticleDOI
Lost primordial continents
TL;DR: In this paper, the bulk density variations of some representative compositions for the lower mantle based on the pressure-volume-temperature equation of state of the constituent mineral phases were investigated at a temperature of 300 k and at lower mantle pressures.
Journal ArticleDOI
The second continent: Existence of granitic continental materials around the bottom of the mantle transition zone
TL;DR: In this paper, it was shown that granitic material has negative buoyancy compared to the surrounding material in the upper mantle and transition zone, and thus can be subducted in the depth range of 270-660 km.
