Introduction to Ultrasonic Water

Following contents of individual isolated fractions were observed by the nuclear magnetic resonance (NMR): ultrasonic water extraction of GS (GSUW) consisted of (1–3)-α-glycan 6-sulfate; ultrasonic carbonate-peroxide extraction (GSUCP) consisted of the same glycan and extra carrageenan hybrids µ-D6S and ν-D2S,6S observed for the first time in this study; extractions of FL and GS in boiling water under reflux (FLW, GSW) contained α-, θ-, λ-, µ-, ν-, and ζ-carrageenans and (1–3)-α-glycan partially sulphated at C6 or the most complex mixture of α-, β-, κ-, ι-, θ-, ζ-carrageenans, and (1–3)-α-glycan partially sulfated at C6, respectively.

biomass with 25 ml of 1% CaCl2 in an ultrasonic water bath at 50 kHz, 300 W at 30 °C for 15 min.

This study investigated how the HF-etching following by ultrasonic water bath cleaning (recommended protocol to improve the bonding with a composite resin), modifies the surface chemistry of a lithium disilicate glass-ceramic and impacts the chemical bonding with silane.

Hence, this paper proposes a delta time-of-flight $(\Delta ToF)$ -based non-intrusive sensor system for plug-and-play ultrasonic water flow rate metering.

Visualization experiments were performed to examine whether acoustic bubbles play a role in ultrasonic water flow cleaning, as in convention cleaning with ultrasonic baths.

Ultrasonic water meters have current widespread problems of poor site adaptability, low measurement accuracy, and poor stability.

If traditional mechanical water meters are replaced by electronic ultrasonic water meters, micro flow rate can be measured and the measurement uncertainty can be improved due to the age of use.

ABSTRACT Aimed at reducing the occurrence of gas explosion accidents, this work explored the mechanism and effect of ultrasonic water mist suppression on gas explosion.

The water mist generated by the ultrasonic water mist generator simulates the fog in the fog-haze environment, and the influence of the haze environment on the roof insulator contamination at different airflow speeds is revealed by artificially simulating the airflow haze environment roof insulator contamination test.

Mathematical processing of the total antioxidant capacity (DPPH) results established a reasonable mode of ultrasonic water treatment used for grain soaking - 400 W for 2 minutes, the total antioxidant capacity will be 2.

As a result, we found that the coiled-up space metamaterial can increase the efficiency of the ultrasonic water treatment by 41% under the resonance condition of the container of the target solution.

The system is based on a network of custom-made ultrasonic water level nodes that transmit data and alarms remotely and in real-time.

This study presents a developed ultrasonic water level detection (UWLD) system with an energy-efficient design and dual-target monitoring.

The present study presented the extraction and purification of polysaccharides from artificially cultured Cordyceps cicadae and wild Cordyceps cicadae by pre-soaking ultrasonic water extraction.
