We develop and demonstrate the use of electrowetting to achieve the dewetting (Wenzel-to-Cassie transition) of superhydrophobic surfaces. We effect this transition by means of an opposing flat plate and a three-electrode system; the liquid droplet is completely pulled out of its wetted Wenzel state upon the application of a suitable voltage. We also experimentally quantify the dissipative force...
A very Jow noise measurement system is described with a noise temperature of 0.5 K consisting of a mercury wetted reed switch, low noise preamplifier, and synchronous detector. The set-up can te tuned from 20 kHz up to 3.15 GHz corresponding to the bandwidth of relay and prcamplifieI'. The shot noise of CdSjCulnSe2-photodiode,s has been investigated. Deviations from the expected behaviour indic...
The interaction between Laponite and other constituents in complex systems greatly depends on its available surface area. We report a study of exfoliation dynamics of Laponite in aqueous suspensions by NMR relaxometry. It showed that Laponite particles exfoliate to the same extent in a concentration range of 0.5-3% w/w. Faster increase of specific wetted surface area of Laponite particles in mo...
Significant progress has been made on addressing critical issues for inertial fusion energy (IFE) chambers for heavy-ion, laser and Z-pinch drivers. A variety of chamber concepts are being investigated including drywall (currently favored for laser IFE), wetted-wall (applicable to both laser and ion drivers), and thickliquid-wall (favored by heavy ion and z-pinch drivers). Recent progress and r...
