A series of experiments is described on grid excited linear and nonlinear ion acoustic waves. multiple ion-acoustic shock formation simulated. The excitation solitons or a dispersing wave train can be used as plasma diagnostic. Electrostatically coupled pseudowaves observed.
Flat, thin and lightweight lamps providing spatially uniform dimmable illumination from active areas as large 400 cm 2 are being developed for general specialty applications. Comprising an array of low-temperature, nonequilibrium microplasmas driven by a dielectric barrier structure operating at pressures typically 400–700 Torr, these have packaged thickness <4 mm yet produce luminance values beyond 26 000 cd m −2 with luminous efficacy approaching 30 lm W −1 . Third generation lamps,...
Summary Background Onychomycosis affects almost 6% of the world population. Topical azoles and systemic antifungal agents are low efficacy can have undesirable side effects. An effective, non‐invasive therapy for onychomycosis is an unmet clinical need. Objective Determine threshold non‐thermal atmospheric plasma (NTAP) to treat in vitro model. Methods A novel toe/nail‐plate model using cadaver nails agarose media inoculated with Candida albicans was exposed a range NTAP doses. Results...
The two- and three-dimensional collision of spherical ion acoustic solitons is experimentally observed. In each case, a new soliton created which approximately satisfies the resonance conditions K̄α = Σni 1K̄i; Ω(K̄α) 1 Ω(K̄i), n number colliding solitons. three dimensions localized along axis collision.
The effects on ion-acoustic wave propagation caused by the introduction of a large biased metal plate close to and parallel separation grid in target chamber double plasma machine are experimentally examined. It is found that can re-excite waves act as an externally controlled phase shifter.
A flat, disk-shaped ion-acoustic soliton has been excited in a large collisionless plasma. The appears to be stable, its amplitude is constant, and broader width perpendicular the direction of propagation slowly decreases as propagates.
An experiment to measure the radiation of ion-acoustic waves from a quadrupole antenna is described.

Electrostatically coupled excitation 3 when only fourth also observed this experiment.
ABSTRACT The radiation of a large amplitude ion-acoustic wave launched from conical antenna is experimentally measured and contrasted with linear radiation. Significant differences are observed.
The propagation of an ion-acoustic soliton in a moving density depression is observed. damping the this found to be slightly less than uniform plasma.
Microplasma lamps with high luminance and a thin, flat form factor have been developed fabricated in sizes up to 1 sq. ft.(930 cm2). A wide variety of new lighting applications are now available due lightweight construction panel thicknesses less than 5mm. Because microplasma photometric performance is independent temperature, the devices instant on/off. The glass enclosure serves as lamp structure, allowing minimal fixturing (when compared conventional systems) which ideal for space...
Summary form only given. The challenge of realizing commercially viable planar lighting tiles lies primarily in the development high efficacy designs which can be manufactured economically. popularity these is further enhanced by environmentally friendly construction free toxic compounds such as mercury and lead, utilizing recycled recyclable materials.Routine fabrication with luminance tunable coordinated color temperature has been achieved using low-cost, production-compatible processes....

It is found that Ion–acoustic waves are diffracted apertures qualitatively same as any other longitudinal or transverse wave Nonlinear exhibit less...
A coaxial low-impedance cable is described for power system surge protective device (SPD) wiring applications, The designed to replace conventional when parallel connecting any SPD which depends on the applied transient voltage function. minimize transmission loss (voltage drop) of lightning and switching transients from point protection components. This accomplished primarily by minimizing inductance through a reduced aspect ratio (major minor diameter). resultant has very low...
