The texture coefficients of the (111) and (200) planes of deposited films of copper were strongly affected by ultrasonic agitation. In general, the texture coefficient of the (111) plane grew without ultrasonic agitation, but that of the (ZOO) plane increased greatly with it. Limiting current densities and cathodic current efficiencies both increased, while grain size was reduced. The stoichiom...
Background and Objective: Hydrolysis of fat, oil and grease by ultrasonic waves is a pre-treatment method before anaerobic digestion which can change their physical, chemical and biological properties. The main purpose of this study was to investigate the efficiency of ultrasonic waves to improve the hydrolysis process and its use as an auxiliary substrate to increase the efficiency of anaerobi...
Both the spectrum and correlation characteristics are important in constructing excitation sequences to realize the multichannel ultrasonic sensors working together. For LFM excitation sequence, there should not be too many simultaneously fired ultrasonic sensors, because of the limited available frequency band of the ultrasonic ranging system. The optimized CFM excitation sequences are propose...
