Purification of small bandgap fullerenes
A process for purification of the previously insoluble empty fullerenes and endohedral metallofullerenes was developed, based on sublimation from the soot and subsequent solubilization by electrochemical reduction. The ...
Complexity of exotic R4's
A smooth manifold which is homeomorphic but not diffeomorphic to R4 is called an exotic R4 . In this paper we construct several examples of such spaces, and define a notion of complexity for smooth manifolds homeomorphic ...
Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
Kinematic analysis of the deformational structures on eastern Isla de Margarita, Venezuela
Because of its strategic location at the intersection of three regional trends, a kinematic study of the deformation on Isla de Margarita was undertaken to provide additional constraints for Caribbean plate tectonic models. ...
Finite-difference seismic wave modeling including surface topography
I present synthetics of seismic wave propagation near free surface topography. The velocity-stress formulations of both the full elastic and viscoelastic wave equations are used, and I have derived exact boundary conditions ...
