Sonoluminescence and sonochemiluminescence from a microreactor

Biodiesel production from soybean oil using ionic liquid as a catalyst in a microreactor

In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content (wt. %) were optimized using Box–Behnken experimental design. In order to predict the FAME conte...

Gutenkunst Sonoluminescence Extracting Light from Water :

compounds on Earth. No known form of life can survive without it, and for a human, a day without water is a day of suffering. Water is such a familiar element in everyday life that one might assume that it is completely understood. Unfortunately, that is not true. Our ignorance is well illustrated by sonoluminescence, the astounding ability of water to concentrate energy from sound waves into f...

Sonoluminescence and Sonochemistry

"Grafting-from" polymerization inside a polyelectrolyte hollow-capsule microreactor.

Over the last decade versatile, electrostatic layer-by-layer (LbL) assembly methods involving polyelectrolytes have been widely used in the preparation of hollow capsules. These capsules can be fabricated by the stepwise adsorption of polyelectrolytes with charges that are opposite from their aqueous media onto templating cores, especially organic or inorganic particles and biopolymers, followe...

Sonoluminescence and bubble fusion*

Sonoluminescence (SL), the phenomenon of light emission from nonlinear motion of a gas bubble, involves an extreme degree of energy focusing. The conditions within the bubble during the last stages of the nearly catastrophic implosion are thought to parallel the efforts aimed at developing inertial confinement fusion. A limited review on the topic of SL and its possible connection to bubble nuc...
