Use of ultrasounds in catalyst preparation leads to higher penetration of the active metal inside the pores of the support and greatly increases the metal dispersion on the support [185]. Major advances in ultrasonic technology have increased the acoustic power and sensitivity of transducers.

This has come about because of modem developments in both ultrasonic technology and in electrochemistry. Thus ultrasonic sources are now readily available in a variety of powers, frequencies, and geometries, capable of various pulse-styles, duty cycles, and other sophistications. Baths, horns, probes, and other reactors are now all available to the experimentalist.

Over the past two decades there have been several studies of human reliability in aircraft structural inspection (Rummel et al. 1989 Spencer and Schurman 1995 Muigatroyd et al. 1994). AU of these to date have examined the reliability of nondestructive inspection (NDI) techniques, such as eddy current and ultrasonic technologies.

Since then there has been a notable increase in this field, supported by the developments in both electrochemical apparatus and methodology and in ultrasonic technology.

Ultrasonic technology has been increasingly used in synthetic applications despite its existence over a century for traditional industrial applications such as cleaning, extraction and emulsification. Over the past few decades, the potential use of ultrasound in synthetic reactions has been explored in laboratory-scale experiments. Due to unique and extreme reaction environment generated within cavitation bubbles, in otherwise a room temperature liquid, a variety of functional materials could be synthesised. 

It should be noted that ultrasonic technology is a non-thermal process and hence very little changes to the physical and functional properties of dairy system is observed due to sonication. In most studies, the processing time required is a few seconds to less than a minute. In order to evaluate the effect of sonication on the constituents of milk, Chandrapala et al. [85] and Shanmugam et al. [86] carried out extensive research in recent years. Their studies have shown that sonication of a dairy system causes very little changes to the physical properties of whey proteins. They observed reversible changes to partial denaturation of whey proteins. In order to see the effect, the constituents of whey proteins, namely, pure- and 3 1 mixtures of p-Lactoglobulin (P-LG) and a-Lactalbumin (a-LA)...
