Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
On the dynamic structure factor, S(q,[omega]), of polymers in dilute solution
(Elsevier, 1981-08)
In principle, interpretation of dynamic scattering experiments requires theoretical calculation of either intermediate scattering functions S(q,t) or dynamic structure factors S(q,[omega]). Although dynamic scattering ...
The influence of a plane boundary on the thermophoretic force in the knudsen regime
(Elsevier, 1987-05)
The effect of a plane diffusely reflecting wall on the thermophoretic force acting on a particle in the Knudsen regime is investigated. A general expression for the force on a particle in a nonuniform gas is given and then ...
Interpretation of dynamic scattering from polymer solutions
(Elsevier, 1980-08)
The theoretical results available for the interpretation of the dynamic scattering from polymer solutions have been re-examined. The scattering law S(q, t) is formulated using the eigenfunction expansion method and the ...
Multiple scattering in small-angle neutron scattering measurements on polymers
(Elsevier, 1983-02)
Multiple scattering corrections in small-angle neutron scattering experiments on polymers have been examined. Numerical calculations show that, for typical experimental conditions, the second-order scattering is less than ...
Concentration dependence of diffusion coefficient at various molecular weights and temperatures
(Elsevier, 1981-09)
The effect of temperature on the concentration dependence of the diffusion coefficient D(c) is investigated experimentally by light scattering using polystyrene with Mw = 179 000 and 900 000 in toluene and cyclohexane at ...
Benchmark results for particle transport in a binary Markov statistical medium
(Elsevier, 1989-10)
We give numerical benchmark results for particle transport in a randomly mixed binary medium, with the mixing statistics described as a homogeneous Markov process. A Monte Carlo procedure is used to generate a physical ...
Soft X-ray emission from a CO 2 laser-heated Z-pinch plasma
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1987-09)
We report results of soft X-ray measurements in which a high-power (10 10 –10 11 W/cm 2 ) CO 2 laser was used to heat a near critical density (<10 19 cm −3 ) helium Z-pinch plasma. Frequency-integrated X-ray data show that ...
Production of XeO * in a CW microwave discharge
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-12)
A low-power CW microwave discharge at 2.45 GHz was used to produce XeO * excimer molecules. It was found that a total gas pressure between 5 and 20 Torr, absorbed power of about 20–100 W, and an oxygen-to-xenon ratio of ...
Electron density measurements of argon surface-wave discharges
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-09)
The electron density of microwave-generated surface-wave discharges in argon have been measured using Stark broadening and calculated from the measured wavelengths of the standing surface wave. Results obtained from these ...
