چکیده
In order to model efficiently the coherent intermittent structures, i.e. the filaments brought about by the nonlinear evolution of the transverse electromagnetic (Weibel) instabilities arising in the interaction of ultraintense relativistic e-beams (REB) with supercompressed deuterium + tritium plasma core, we propose to consider them as caviton seeds for the electrostatic 3D Langmuir fully developed turbulence [1], [2]

Langmuir monolayers of bent-core molecules.
A systematic study of five different, symmetric bent-core liquid crystals in Langmuir thin films at the air/water interface is presented. Both the end chains (siloxane vs hydrocarbon) and the core (more or less amphiphilic) are varied, to allow an exploration of different possible layer structures at the interface. The characterization includes systematic surface pressure isotherms, Brewster an...
متن کاملPhase diagrams of self-assembled mono-tethered nanospheres from molecular simulation and comparison to surfactants.
We perform Brownian dynamics simulations on model 3-D systems of mono-tethered nanospheres (TNS) to study the equilibrium morphologies formed by their self-assembly in a selective solvent. We predict that in contrast to flexible amphiphiles the nanospheres are locally ordered and there is an increase in the local order with an increase in concentration or relative nanoparticle diameter. We pres...
متن کاملExperimental and numerical insights into isotropic spreading and deterministic dewetting of dielectrowetted films.
Dielectrowetting effects of surface wrinkling, isotropic vs anisotropic spreading, electrode geometry, and deterministic dewetting are presented both experimentally and by 3D numerical modeling. The numerical results are generated by COMSOL in conjunction with the phase-field and electrohydrodynamic methods, including comparisons to experimental data. The dynamic behavior of the two-phase syste...
متن کاملStripe domain phase of a thin nematic film and the K13 divergence term.
To verify the status of the divergence K» term in the elastic theory of liquid crystals we study submicron films placed onto an isotropic fluid substrate in the Langmuir trough (Langmuir liquid crystal, LLC). The upper and lower surfaces favor normal and tangential molecular orientation, respectively. The periodic domain phase is observed in a nematic LLC. The dependence of the periodicity L of...
متن کاملComparative properties of siloxane vs phosphonate monolayers on a key titanium alloy.
A direct comparison of surface loading, interface shear strength, and interface hydrolytic stability was made between a phosphonate and two siloxane monolayers formed on the native oxide surface of Ti-6Al-4V. Surface loading for the phosphonate was ca. four times greater (on a nanomole/area basis) than for the siloxanes; mechanical strengths per surface-bound molecule were comparable, but the h...
