This is the alumni magazine of the Department of Chemistry at Virginia Tech. Inside: Joseph M. DeSimone proves that green chemistry can provide a clean environment.
Switching behavior of semiconducting carbon nanotubes under an external electric field
(AIP Publishing, 2001-04)
We investigate theoretically the switching characteristics of semiconducting carbon nanotubes connected to gold electrodes under an external (gate) electric field. We find that the external introduction of holes is necessary ...
Effect of inertia on drop breakup under shear
(American Institute of Physics, 2001-01)
A spherical drop, placed in a second liquid of the same density and viscosity, is subjected to shear between parallel walls. The subsequent flow is investigated numerically with a volume-of-fluid continuous-surface-force ...
Sound-ultrasound interaction in bubbly fluids: Theory and possible applications
(American Institute of Physics, 2001-12)
The interaction between sound and ultrasound waves in a weakly compressible viscous liquid with gas bubbles is considered. Using the method of multiple scales one- and two-dimensional nonlinear interaction equations are ...
Scalings for fragments produced from drop breakup in shear flow with inertia
(American Institute of Physics, 2001-08)
When a drop is sheared in a matrix liquid, the largest daughter drops are produced by elongative end pinching. The daughter drop size is found to scale with the critical drop size that would occur under the same flow ...
Crustal structure beneath southern Africa and its implications for the formation and evolution of the Kaapvaal and Zimbabwe cratons
(American Geophysical Union, 2001-07-01)
The formation of Archean crust appears to involve processes unique to early earth history. Initial results from receiver function analysis of crustal structure beneath 81 broadband stations deployed across southern Africa ...
Microscopic kinetics and time-dependent structure factors
(American Physical Society, 2001-08-06)
The time evolution of structure factors (SF) in the disordering process of an initially phase-separated lattice depends crucially on the microscopic disordering mechanism, such as Kawasaki dynamics (KD) or vacancy-mediated ...
Interaction of singlet excitons with polarons in wide band-gap organic semiconductors: A quantitative study
(American Physical Society, 2001-10-15)
The steady-state photoinduced absorption (PA), photoluminescence (PL), PL-detected magnetic resonance (PLDMR), and PA-detected magnetic resonance (PADMR) of poly- and oligo-(para-phenylenes) films is described. In particular, ...
Critical behaviour of driven bilayer systems: a field-theoretic renormalization group study
(Iop Publishing Ltd, 2001-10-26)
Universal torsion induced interaction from large extra dimensions
(Amer Inst Physics, 2001-01-01)
