TL;DR: The present method of purification and crystallization of C(60)-based metallofullerenes provides a new C( 60) fullerene material that contains a metal atom that has a unique two-dimensional structure.

TL;DR: In this article, the authors examined the crystal structures, magnetic properties and conductivity of undoped (normal conductor) and 14.5% F-doped LaFeAsO (Tc = 20?K) by synchrotron x-ray diffraction (XRD), DC magnetic measurements, and ab?initio calculations demonstrated that the anomaly is associated with a phase transition from tetragonal (P4/nmm) to orthorhombic (Cmma) phases at ~160?K as well as an antiferromagnetic spin ordering transition at

TL;DR: These structures suggest a bond-interchange model, where a sequence of small displacements of Sb atoms accompanied by interchanges of short and long bonds is the origin of the rapid crystallization of a-AIST, which differs profoundly from crystallization in a-GST.

TL;DR: In this article, high-energy x-ray diffraction beamlines and a dedicated diffractometer for glass, liquid and amorphous materials at SPring-8 were introduced.

TL;DR: Global Oscillation Network Group data reveal that the internal structure of the sun can be well represented by a calibrated standard model, however, immediately beneath the convection zone and at the edge of the energy-generating core, the sound-speed variation is somewhat smoother in the sun than it is in the model.
