โœฆ Synopsis

We propose one possible geometry of the metallofullerene La& which has been obtained by pursuing the most probable reaction process of La, C6,,, and smaller carbon clusters, It naturally explains why CBz instead of Cm is special for metallofullerenes, why C6,, becomes much less abundant in the metallofullerene production process, why La&,, needs 22 more C atoms for one more La atom, and why the maximum Mof La,,,&is 4. The Cs2 cage structure proposed is found to be one of the stable structures of Cg2 within the empirical potential for C atoms, and is expected to be further stabilized by electron transfer from the trapped La

In view of the growing interest in endohedral lanthanide fullerenes, the electronic structure and properties of CeCel are investigated as an example from a theoretical point of view. Unlike current expectation, it is suggested that the electronic state is formally described as Ce2+CiF. In order to c

Our goal was to understand developmental determinants of femoral structure during growth and sexual maturation by relating femoral measurements to gender and developmental factors (age, pubertal stage, height, and body mass). The bone mineral content of the femur was measured by dual energy x-ray ab
