Ultrasonic atomization of the DNA solution for atomic force microscopy
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1995We have investigated the ultrasonic atomization of the deoxyribonucleic acid (DNA) solution as a simple preparation technique to image circular DNA molecules with the atomic force microscope. The DNA solution with a relatively high concentration (∼25 μg/ml) is ultrasonically atomized at the exciting frequency of 2.4 MHz.

Ultrasonic atomization: Effect of liquid phase properties
Ultrasonics, 2006Experiments have been conducted to understand the mechanism by which the ultrasonic vibration at the gas liquid interface causes the atomization of liquid. For this purpose, aqueous solutions having different viscosities and liquids showing Newtonian (aqueous solution of glycerin) and non-Newtonian behavior (aqueous solution of sodium salt of carboxy ...

High-Frequency Ultrasonic Atomization With Pulsed Excitation
Journal of Fluids Engineering, 2003Ultrasonic atomization is a very convenient method to produce sprays of very small droplets. Resulting droplet size distributions are very narrow and the mean diameter is essentially only controlled by the excitation frequency. Generation of droplets in the micron range requires MHz waves, with voltages around 30 V, which translates into power ...

Ultrasonic Atomization Amount for Different Frequencies
Japanese Journal of Applied Physics, 2011The mass flow rate of ultrasonic atomization was estimated by measuring the vaporization amount from a bulk liquid with a fountain. The effects of ultrasonic frequency and intensity on the atomization characteristics were investigated when the directivities of the acoustic field from a transducer were almost the same.

Design and Atomization Experiments of an Ultrasonic Atomizer with a Levitation Mechanism
Applied Engineering in Agriculture, 2016According to Lang equation, the diameter of droplet generated by an ultrasonic atomizer is inversely proportional to the ultrasonic drive frequency to the two-thirds power. In an ultrasonic aeroponic cultivation system, nutrient solution droplet sizes influence plant growth speed directly.

Ultrasonic Atomic Force Microscopy UAFM
2012A version of scanning probe acoustic technique was developed as ultrasonic atomic force microscopy (UAFM), where higher order mode cantilever vibration is excited at its base (support). It enables precise imaging of both topography and elasticity of stiff samples such as metals and ceramics, without a need for bonding a transducer to the sample.
