“…Ultrasonic sound propagates through various materials influenced by sound pressure. In the liquid state, atoms or molecules are interconnected or attracted through interactive molecular interactions, generating excess pressure that facilitates the propagation of sound waves through the experimental liquid [28]. Studies examining the frequency of ulcers have indicated adverse effects associated with Sodium Lauryl Sulphate (SLS).…”

Surfactants have high important application in everyday life due to its amphiphilic nature. Ionic surfactants have either positive or negative charge on its head group making it cationic and anionic in nature. The physical properties of binary solutions of SDS-CTAB in water were thoroughly examined across various mole fraction ratios at temperatures of 298K and 308K. These properties included relative densities, relative viscosities, specific conductance, and the velocity of sound measured through the solutions. Utilizing this data, several critical physical parameters such as adiabatic compressibility (βad), intermolecular free length (Lf), acoustic impedance (Z), viscous relaxation time (τ), and molar free volume (Vf) were calculated using established formulas and relationships. The results obtained from these calculations suggest a compelling presence of molecular interactions between the cationic and anionic surfactants within the solution. These interactions appear to be of an associative nature, indicating a cooperative relationship between the molecules involved. The investigated values of the physical properties support this notion, reinforcing the feasibility of molecular interaction within the SDS-CTAB binary solutions. Furthermore, the derived acoustical and adiabatic parameters exhibit a strong correlation with the experimental observations, signifying the accuracy and reliability of the findings. These parameters collectively provide insights into the nature and characteristics of the interactions occurring between the cationic and anionic surfactants in the solution, highlighting their impact on the overall properties and behaviour of the system.

“…A number of studies have considered how to transmit and receive longitudinal and shear waves for nondestructive evaluation. [27][28][29][30] The probes described in existing research, however, cannot measure the direction of particle displacement and transmit a wave having the particle displacement in an arbitrary direction, because the probes cannot control the direction of the sensitive axis. In the proposed method, either longitudinal or shear waves are transmitted in an arbitrary direction by controlling the vibration direction of the 3-DOF probe.…”

In this study, we propose and evaluate an ultrasonic probe for the beam forming of longitudinal and shear waves by the two-dimensional finite element method. Ultrasonic probes for longitudinal and shear waves are used in industrial fields for nondestructive testing. Among the ultrasonic probes, array probes can undertake a range of inspections from a single location, and so are more flexible than single-element probes. Most types of array can be used to produce images at each test location. This allows rapid visualization of the internal structure of a component. In order to restrain artifacts for an ultrasonic array flaw-detecting method, we propose an array probe with three degrees of freedom. Operations of the probe were verified using the two-dimensional finite element method. In the case of transmission, we found that secondarily generated beams that might be artifacts were restrained by controlling the vibration direction of the proposed probes; for reception, an array of proposed probes could obtain the direction of particle displacement. Thus, the results suggest that an array of the proposed probes can distinguish longitudinal from shear waves.

A novel equipment for measuring the elastic wave velocity of rocks under various temperature and pressure conditions of ultra-deep reservoirs has been developed. The equipment consists of a high pressure and high temperature experimental platform and an ultrasonic measurement system, which can measure the elastic wave velocity of rocks under conditions of ultra-deep reservoirs up to a depth of 13 km by the ultrasonic reflection method. The method of assembling rock samples has also been improved to acquire high-quality ultrasonic signals. The feasibility of the new equipment was tested by measuring the elastic wave velocity of dolomite and limestone. The experimental results are consistent with the previous research. The elastic wave velocity of rocks measured by this equipment can be potentially used for the exploration of ultra-deep oil and gas resources.
