Salt doped poly ethylene oxide (PEO) mixtures were investigated by means of both small angle neutron scattering and QENS techniques aiming to characterize morphological and dynamical features in the melt state. These experimental evidences provide su

The technique of neutron diffraction with isotope substitution has been used to probe the hydration structure around the Ni2þ ion in a concentrated aqueous solution of 3.87 m NiCl2. The scattering from two heavy water solutions containing, respectiv

Scanning tunneling microscopy (STM) has been used as the primary tool to examine mesophase pitch-based carbon fibers ranging in modulus from 280–750 GPa. STM revealed a sheet-like structure for the carbon basal planes. These sheets were found to be

Theoretical expressions for the motion of spherical aerosol particles in gas mixtures having both temperature and composition gradients are obtained that cover the free-molecule to the continuum regime. The theoretical model treats the aerosol partic

The neutron scattering difference method is described and applied to investigations of the aqua rare-earth ions, Nd/sup 3 +/ and Dy/sup 3 +/. Metal-water distances and hydration numbers have been unambiguously determined for these ions' inner coordin

Beams of UF − 6 and MoF − 6 of controlled average internal energy from 0.7 to 2.4 eV have been collided with argon at 200 eV laboratory kinetic energy. Analysis of the outgoing kinetic energy distributions shows that increased internal excitation

Theoretical expressions for the motion of spherical aerosol particles in a diffusing gas mixture are obtained that cover the free-molecule to the continuum regime. The theoretical model used treats the aerosol particles as one component of a multicom

An expression for the pressure dependence of the drag exerted on a spherical aerosol particle by a flowing gas is derived by dividing the problem into two parts, one which is concerned with viscous effects, and another which is concerned with diffusi

Measurements are presented of the kinetic energy loss of 200 eV (lab) UF − 6 ions in collisions with Ar atoms. Depending upon the angle of scatter, the results show clear evidence for production of UFUF − 6 ions with internal excitation up to 5 e
