Contact our sales team Corporate Partners Mar 1, 1999 Ever since it was discovered that sound waves can cause an air bubble trapped in water to emit light, physicists and chemists have puzzled over the phenomenon of sonoluminescence. The sound waves cause the bubble to expand and contract, with short flashes of light being emitted the instant the bubble reaches its minimum radius. Single-bubble sonoluminescence was first observed in 1989 by the author as part of his PhD research at the University of Mississippi (see, for example

Extractions: II: What is the light emitting mechanism? Question I can be answered along a hydrodynamical/chemical approach which we elaborated in the recent years: For SBSL to occur, the bubble collapse has to be violent enough to ensure energy transfer from the fluid to the gas in the bubble and strong enough heating of the gas inside the bubble.

Genetically engineered goats will be used to produce milk loaded with spider silk, five times as strong, by weight, as steel; tough enough to make a new generation of soft body armor or the finest surgical thread. "It's incredible that a tiny animal found literally in your backyard can create such an amazing material by using only amino acids, the same building blocks that are used to make skin and hair," said Jeffrey Turner, President of Nexia. "Spider silk is a material science wonder - a self-assembling, biodegradable, high-performance, nanofiber structure one-tenth the width of a human hair that can stop a bee traveling at 20 miles per hour without breaking. Spider silk has dwarfed Man's achievements in material science to date."
Sonofusion, Acoustic Inertial Confinement Fusion sonoluminescence occurs when sonic pressure waves cause the growth and subsequent . Comments on the possible observation of dd fusion in sonoluminescence http://home.fuse.net/clymer/snf/
Extractions: Sonofusion The Star in a Jar History of Sonofusion Sonofusion Calculations Other Links Sonoluminescence occurs when sonic pressure waves cause the growth and subsequent collapse of microscopic bubbles. Due to the high pressures released during the collapse of the bubbles, energy can be emitted in the form of light, hence sonoluminescence. If the energy is great enough, it is thought that fusion reactions can be initiated, or sonofusion. Sonofusion or bubble cavitation is thought to be more correctly termed acoustic inertial confinement fusion (acoustic ICF). History of Sonofusion The earliest reference I have found on a sonofusion-type process is a patent by Hugh G. Flynn , a professor at the University of Rochester. Flynn passed away in 1997.

Extractions: Students begin their exploration by first understanding some basic acoustical principles, such as resonance behavior, quality factors, variation of sound speed with temperature, and the eigenmode structure of a 3-dimensional resonance "cavity." Once these principles are understood there are a large number of experiments that can be performed focusing on the liquid sample preparation and the light emitted from the bubble.
Extractions: Host your own blog here! Using a technique employed by astronomers to determine stellar surface temperatures, chemists at the University of Illinois at Urbana-Champaign have measured the temperature inside a single, acoustically driven collapsing bubble. Their results seem out of this world. "When bubbles in a liquid get compressed, the insides get hot very hot," said Ken Suslick, the Marvin T. Schmidt Professor of Chemistry at Illinois and a researcher at the Beckman Institute for Advanced Science and Technology. "Nobody has been able to measure the temperature inside a single collapsing bubble before. The temperature we measured about 20,000 degrees Kelvin is four times hotter than the surface of our sun."

In somoluminescence, the bubble will collapse violent ly just after creation and release light for a few picosecond s.

It was first discovered in 1934 at the University of Cologne but deemed rather uninteresting Today, the question of how the energy of sound (rather low in the energy density ) is concentrated in the space of a micron to make it emit light. To reach this, it requires the concentration of the energy by a factor of about one trillion To produce sonoluminescence

Symposium On Sonoluminescence Provides abstracts for a symposium held at the University of Chicago in 1997. http://mrsec.uchicago.edu/meetings/sonoluminescence/
Extractions: At the campus of the University of Chicago , the world's leading experts will have the opportunity to discuss, and share with young scientists, the new trends and results on this important interdisciplinary field of sonoluminescence. The meeting is sponsored by the NSF Materials Center at the University of Chicago. The scientific programme will present an overview of the state of art on all aspects of sonoluminescence. The symposium, which is supposed to stimulate interactions between the participants, will consist of a number of invited lectures and shorter contributed presentations. In order to promote intense but relaxed, exchange of ideas, ample time for discussion will be provided for each talk.
