Ferroelectric—polymer composite devices have been developed for large-area transducers, active noise control, and medical imaging appHcations. North American Philips, Hewlett-Packard, and Toshiba make composite medical imaging probes for in-house use. Krautkramer Branson Co. produces the same purpose composite transducer for the open market. NTK Technical Ceramics and Mitsubishi Petrochemical market ferroelectric—polymer composite materials (108) for various device appHcations, such as a towed array hydrophone and robotic use. Whereas the composite market is growing with the invention of new devices, total unit volume and doUar amounts are small compared to the ferroelectric capacitor and ferroelectric—piezoelectric ceramic markets (see Medical imaging technology).

Figure 3-4. Dimensions of a fully extended polypeptide chain. The four atoms of the peptide bond (colored blue) are coplanar. The unshaded atoms are the a-carbon atom, the a-hydrogen atom, and the a-R group of the particular amino acid. Free rotation can occur about the bonds that connect the a-carbon with the a-nitrogen and with the a-carbonyl carbon (blue arrows). The extended polypeptide chain is thus a semirigid structure with two-thirds of the atoms of the backbone held in a fixed planar relationship one to another. The distance between adjacent a-carbon atoms is 0.36 nm (3.6 A). The interatomic distances and bond angles, which are not equivalent, are also shown.

A commercially available ultrasonic cleaner was used for the prqjaration of nickel powders from nickel salt in aqueous solution. This cleaner, Model 3210 (Branson Ultrasonic Corp., CT), is normally used as a cleaning apparatus, working at a frequency of 47 kHz with e power of 130 W that consists of a stainless-steel bath of 5.17 1 capacity and has an ultrasonic transducer attached to the bottom of the bath. A liquid solution temperature in the bath can be varied from room temperature to maximum of 80 °C.

Pandit and co-workers have shown that scale-up may be possible on a more rational basis if cavitation is employed, and some data have been reported by Pandit and Mohalkar (1996), Mohalkar et al. (1999), Senthil et al. (1999), and Cains et al. (1998). A variety of reactors can be used, viz. the liquid whistle reactor, the Branson sonochemical reactor, the Pote reactor, etc. The principal factors affecting the efficiency of a hydrodynamic cavitation reactor are irreversible loss in pressure head and turbulence and friction losses in the reaction rates.

The sonochemical reduction of Au(III) has been investigated under Ar in the presence of 20 mM 1-propanol at different frequencies, where two types of ultrasound irradiation systems were used one is a horn type sonicator (Branson 450-D, frequency 20 kHz, diameter of Ti tip 19 mm) and the other is a standing wave sonication system with a series of transducers operating at different ultrasound frequencies (L-3 Communication ELAK Nautik GmbH, frequency 213, 358, 647, and 1,062 kHz, diameter of oscillator 55mm) [33]. All experiments were performed at a constant ultrasound intensity ((0.1+/—0.01 W mL-1), which was determined by calorimetry.

For reaction on a 10-mmol scale, an ultrasonic cleaner with sufficient output power (e.g., Branson Model B-220) can be used for external irradiation.

For the specific amplification of C. moewusii genomic hydA DNA, a C. moewusii colony was scraped from an agar plate and resuspended in 10 mM Tris-HCl, 10 mM EDTA and 150 mM NaCl. After disrupting the cells (Cell disruptor B 15, Branson, Danbury, USA), 2 pi of the resulting suspension was used directly in the PCR. 

When an electrostatic field is applied so rapidly that flow phenomena cannot occur (or in the case of a solid, which does not flow), breakup may not occur until the electrostatic stress exceeds the tensile strength of the liquid. Schultz and Branson (S2) and Schultz and Wiech (S3) claim that this is the case in their liquid atomization studies. For this case, at breakup,... 

A large part of the interest in electrostatic atomization has arisen from two fields of interest combustion of fuel oils and ion propulsion of rockets in space. Work in the latter area has been concerned primarily with atomization at high vacuum (10-8 atm) as in the work of Cohen (C5), Hogan (HI2, 13), Hendricks (H6), Schultz and Branson (S2), and Schultz and Wiech (S3). Graf (G8), Matthews and Mason (M3), Peskin and Raco (P3), Randall, Marshall, and Tschernitz (Rl), and Vonnegut and Neubauer (V4) have been concerned primarily with atomization at atmospheric pressure. Most of the...
