Abstract :
When a gas bubble in a liquid is
excited by ultrasonic acoustic waves it can emit short flashes of light suggestive of
extreme temperatures inside the bubble. These flashes of light known as
sonoluminescence, occur as the bubble implode or cavitates. It is show that
chemical reactions occur during cavitations of a single, isolated bubble and yield of photons,
radicals and ions formed. That is gas bubbles in a liquid can convert sound
energy in to light.
Sonoluminescence also called
single-bubble sonoluminescence involves a single gas bubble that is trapped inside the flask by a
pressure field. For this loud speakers are used to create pressure waves and
for bubbles naturally occurring gas bubbles are used. These bubbles can not
withstand the excitation pressures higher than about 170 kilopascals.
Pressures higher than about 170 kilopascals would always
dislodge the bubble from its stable position and disperse it in the liquid. A
pressure at least ten times that pressure level to implode the bubbles is
necessary to trigger thermonuclear fusion. The idea of sonofusion overcomes these limitations.
APPLICATIONS
1) Thermonuclear fusion gives a new,
safe, environmental friendly way to produce electrical energy.
2) This technology also could result in
a new class of low cost, compact detectors for
security applications. That use
neutrons to probe the contents of suitcases.
3) Devices for research that use
neutrons to analyze the molecular structure of materials.
4) Machines that cheaply manufacture
new synthetic materials and efficiently produce tritium, which is used for numerous applications ranging from
medical imaging to watch dials.
5) A new technique to study various phenomenon’s in cosmology, including the working of neutron star and black holes.
