Functional nanoparticles comprised of liquid metals, such as eutectic gallium indium (EGaIn) and Galinstan, present exciting opportunities in the fields of flexible electronics, sensors, catalysts, and drug delivery systems. Methods used currently for producing liquid metal nanoparticles have significant disadvantages as they rely on both bulky and expensive high‐power sonication probe systems, and...
The realization of automatic frequency tracking is of great significance in ultrasonic transducer due to its wide application area in nowadays industrial manufacture. However, excessive overshoot current, serious overheating and long response time remain the urgent issue. To tackle these existing ultrasonic frequency tracking problem, this paper proposes a hybrid technique that integrates fuzzy control...
Micro‐ to nanosized droplets of liquid metals, such as eutectic gallium indium (EGaIn) and Galinstan, have been used for developing a variety of applications in flexible electronics, sensors, catalysts, and drug delivery systems. Currently used methods for producing micro‐ to nanosized droplets of such liquid metals possess one or several drawbacks, including the lack in ability to control the size...
In application of the acoustical theory, a method of noise prediction and measures of reducing noise in highway tunnel is investigated in combination with the highway tunnel engineering. A prediction model, the method of determination of the parameters, the calculating example and several scheme comparisons of reducing noise are presented.
