Single bubble sonoluminescence
… attention has been directed to the phenomenon of single bubble sonoluminescence, SBSL in which a single, stable, acoustically levitated bubble is made to oscillate with sufficiently large amplitude so as to emit picosecond light pulses in each cycle of the acoustic drive pressure. Remarkably, the …

Single-bubble sonoluminescence
… by which nonvolatile species enter a cavitating bubble’s core and emit light, sulfuric acid (H2SO4) and a surfactant sodium dodecyl sulfate (SDS) were explored for studies of single-bubble sonoluminescence (SBSL) to test the heated shell model of nonvolatile vaporization. It was found that the …

Spectroscopic Studies of Multi -Bubble and Single Bubble Sonoluminescence
Single bubble sonoluminescence (SBSL) was also studied. Small concentrations of organic solutes suppress SBSL from water containing dissolved air, but only when the solvents are volatile and can enter the bubble interior. These results were interpreted in light of the dissociation hypothesis for …

Physical Conditions and Chemical Processes During Single-Bubble Sonoluminescence
… and chemical processes associated with single-bubble sonoluminescence (SBSL), nonvolatile liquids such as concentrated sulfuric acid (H2SO 4) were explored. The SBSL radiant powers from H2SO 4 aqueous solutions were found to be over 103 times larger than those typically observed for SBSL …

Mechanoluminescence and Sonoluminescence From Acoustic Cavitation
The effect of single-bubble sonoluminescence (SBSL) intensity and spectral profile from the addition of low concentrations of organics to sulfuric acid has been investigated. It was found that the addition of small quantities of organics to sulfuric acid greatly reduced the total SBSL intensity. …

Bubbles and crystals: time-resolved sonoluminescence, sonocrystallization, and sonofragmentation
… the formation, growth, and implosive collapse of bubbles. In a standing wave a single bubble can be trapped. The conditions formed inside such a bubble during collapse are extreme, reaching temperatures on the order of 15,000 K and pressures of over a thousand atmospheres. These conditions are …

Chemical and physical effects of ultrasound: sonoluminescence and materials
… formation, growth, and implosive collapse of bubbles in liquids irradiated with ultrasound) generally occurs. This is the phenomenon responsible for the driving of chemical reactions (sonochemistry) and the emission of light (sonoluminescence). The implosive collapse of bubbles in liquids …
