The behavior of the primary radicals formed from the random scission of anionically polymerized poly(methyl methacrylate). PMMA, during thermal degradation is
We have measured the viscosity of four binary mixtures near their consolute points: (1) methanol + cyclohexane, (2) isobutyric acid + water, (3) nitroethane + 3

General and specific fragmentation pathways of trifluoroacetyl and heptafluorobutyryl derivatives of primary and secondary amines under electron ionization are
The interaction between two test charges in a solid can be described in terms of a total dielectric function that includes electronic and lattice polarization
A transition between a coplanar probe and a microstrip transmission line is reported. The transition is significant in that it does not require substrate via
The capabilities for representing and reasoning about three-dimensional objects are essential for knowledge-based, 3D photo-interpretation system that combine
We calculate the transport critical-current density in a granular superconductor in magnetic fileds below about 5 x 10^-3 T. The field dependence in this region
