Abstract:

Different types of radiations have been found to be widely applicable in modifying the properties of materials. In this work colour strength (K/S) and colour fastness of reactive dyed cotton fabric has been studied with the application of three radiations; microwave, ultraviolet and ultrasonic. Analysis of variance and comparison of mean values statistical tests were carried out to find out the effect of different radiation treatment time and fabric density on colour strength of cotton fabrics. The colour strength (K/S) of dyed fabric enhanced significantly by pretreatment with different radia

Abstract:

Theoretical methods of classical mathematical physics investigate the acoustic and electromagnetic radiation generated by capillary oscillations of a charged drop of an ideal uncompressible electroconductive fluid in an ideal nonconductive medium. The radiations discussed are found in first-order analytical asymptotic calculations of smallness by the dimensionless amplitude of droplet oscillations. Analytical expressions were found for the intensity of acoustic and electromagnetic radiation, which differ by several orders of magnitude and fall on different frequency bands. Acoustic radiation f

Abstract:

The fuel element plates of research reactors are subjected to swelling phenomena. These structure modifications impact an initial inter-plate distance of 1.8 mm. An ultrasonic device has been developed to investigate this parameter. With a 1 mm thickness, it relies on two transducers linked to an electronic system. The feasibility of the distance measurement has been proved in a previous study and the irradiation impact on the transducer components is here studied. To do so, a radiation resistance experiment was realized in the Arc-Nucleart Institute of Grenoble. It allowed the study of the in

A convenient approach for the synthesis of β-cyanoepoxides is illustrated by iodine(III)-catalyzed epoxidation of electron-deficient β-cyanostyrenes, wherein the active catalytic iodine(III) species was generated in situ. The epoxidation of β-cyanostyrenes was performed using 10 mol% PhI as precatalyst in the presence of 2.0 equivalents Oxone as an oxidant and 2.4 equivalents of TFA as an additive at room temperature under ultrasonic radiations. The β-cyanoepoxides were isolated in good to excellent yields in a short reaction time.

Abstract:

Second generation bioethanol production technology relies on lignocellulosic biomass composed of hemicelluloses, celluloses, and lignin components. Cellulose and hemicellulose are sources of fermentable sugars. But the structural characteristics of lignocelluloses pose hindrance to the conversion of these sugar polysaccharides into ethanol. The process of ethanol production, therefore, involves an expensive and energy intensive step of pretreatment, which reduces the recalcitrance of lignocellulose and makes feedstock more susceptible to saccharification.

Abstract:

Ultrasonic particle manipulation is a noncontact method for controlling microscale objects, such as cells or microparticles, using an acoustic field. In this study, a 2D array of capacitive micromachined ultrasonic transducers (CMUTs), placed horizontally in immersion, generated ultrasonic waves in the vertical direction, and the oil’s surface increased due to the radiation force of the ultrasonic waves. In addition, the radiation force directly exerted a force on a floating particle. By measuring the movement of the reflected laser light by the moving oil surface, the height of the oil’s surf

Abstract:

The article presents the research of the efficiency of the modernized directional ultrasonic disk radiators equipped with reflectors, phase-aligning cones and horns. Using the experimental setup consisting of two directional ultrasonic radiators operating at a close resonant frequency, the data for constructing the radiation patterns, determining the acoustic power and calculating the linear attenuation were obtained. It was found that the reflectors allow to increase the sound pressure of the radiator array by 3.5 dB, providing the angle of the main lobe of the radiation pattern within ±7.5 d

To address the limitations of conventional one-dimensional longitudinal vibration transducers in terms of single-directional acoustic radiation and limited radiation area, this study proposes a novel longitudinal-bending orthogonal coupled piezoelectric ultrasonic vibration system(The vibration schematic diagram of the vibration system is shown in Fig.16.). By synergistically integrating the orthogonal longitudinal vibration of a sandwich-type piezoelectric transducer, displacement amplification via conical horns, and flexural vibration of metal disks, the system achieves two-dimensional four-

Abstract:

The pressure field induced by cavitaion bubble is responsible for the grinding mechanism and the cutting chatter of power ultrasonic honing. Based on the cavitation bubble dynamics model in the grinding area of power ultrasonic honing, the radiation pressure field of cavitation bubble was established. Experimental results show that the bubble is distributed in the grinding area like honeycomb and the size is about 10μm. Numerical simulation of dynamics and pressure field of cavitation bubble was performed. Numerical results show the dynamic behavior of cavitation bubble presents grow, expend a

Abstract Proper treatment of wastewater is key to the achievement of sustainable environmental management. The use of ultraviolet radiation and ultrasound have continued to be considered as some of the best sustainable practices in wastewater purification. However, despite the suitability of the two emerging techniques in sustainably increasing the purification efficiencies of wastewater, their application has not been fully understood, especially in eliminating faecal pathogenic microorganisms. Moreover, their combined potential in the elimination of Escherichia coli resistant genes from wast

The influence of ultra-high-frequency and ultrasonic radiation on the process of extraction of flavonoids from Sophora japonica fruits was studied. Treatment with ultra-high-frequency and ltrasonic radiation was carried out after swelling of pre-crushed Sophora japonica fruits in the extractant. Then the flavonoids were extracted by maceration and heating. The amount of flavonoids in the extract was determined by photocolorimetry. It was shown that the yield of flavonoids depends on the duration and method of exposure and on the extraction method. The highest yield after xposure to ultra-high-

Abstract:

Several radiation boundary conditions for inhomogeneous acoustic media are investigated. Previous investigators have developed various approximate radiation conditions and have studied their accuracy by calculating an effective reflection coefficient for plane waves incident on such radiating boundaries. In this paper, it is shown that effective reflection coefficients can be calculated for a class of parabolic approximations to the Helmholtz equation. These results are valid for vertically heterogeneous media. Comparison of these radiation conditions is given through numerical examples.

This precursor precipitant completely transformed to pure YAG phase after being calcined at 900 °C for 4 h. The properties of YAG nanopowders obtained under different synthetic process were studied by XRD, TG-DSC, FT-IR and SEM. The results show that the ultrasonic radiation can fine the precursor and reduce its agglomeration. YAG nanopowders with an average particle size of about 60 nm were obtained and particles were sphere-shaped with good dispersity.
