The antibacterial and antifungal properties of ultrasonically synthesized silver nanomaterials (US-AgNPs) were also investigated. US-AgNPs are important nanomaterials that can find many good applications in practice.

Effect of Ultrasonic Vibration Assistance on Microstructure Evolution and Mechanical Properties in Laser-Welded AZ31B Magnesium Alloy

Given the susceptibility to weld porosity and poor weld formability in laser beam welding (LBW), this study delves into an examination of the impact of ultrasonic vibrations on microstructural morphologies and mechanical properties in AZ31B magnesium (Mg) alloy. A comparative analysis was conducted between ultrasonic vibration-assisted LBW and conventional LBW. The results established that the effective elimination of weld porosity, an outcome attributed to the combined effects of cavitation and acoustic streaming, resulted in a weld characterized by a visually seamless and structurally robust appearance. Furthermore, the incorporation of ultrasonic vibration assistance in the welding process yielded a finer microstructure as compared to the conventional LBW. Moreover, the lamellar structures of β-Mg17Al12 were transformed into particles and evenly distributed throughout the α-Mg matrix. In addition, the incorporation of 50% ultrasonic vibration assistance yielded notable improvements in tensile strength (259.6 MPa) and elongation (11.1%). These values represented enhancements of 4.8% and 35.4% as compared to joints fabricated by using conventional LBW.

Sonochemical‐Assisted Synthesis of Ultrathin NiCu layered Double Hydroxide for Enhanced CN Coupling toward Electrocatalytic Urea Synthesis

The electrocatalytic carbon–nitrogen (CN) coupling, facilitating one‐step urea synthesis under ambient conditions, holds great promise as a viable alternative to conventional protocols. However, developing efficient and low‐cost electrocatalysts for CN coupling remains a great challenge. Herein, a “bottom‐up” strategy is proposed to synthesize multidimensional hybrid materials of ultrathin NiCu layered double hydroxide (LDH) nanosheets on carbon nanofiber (u‐NiCu‐LDH/CNF) through an ultrasonic‐assisted solvothermal method. The NiCu‐LDH nanosheets in the u‐NiCu‐LDH/CNF composite exhibit a significantly thinner morphology compared to NiCu‐LDH/CNF prepared by conventional solvothermal without ultrasonic assistance. Leveraging its large specific surface area and well‐exposed active sites, the u‐NiCu‐LDH/CNF demonstrates dramatically improved electrocatalytic activity in CN coupling for urea production, leading to a satisfactory urea yield rate (19.43 mmol g−1 h−1) and a high Faradaic efficiency (13.95%). Density functional theory calculations reveal that the CN coupling step on the NiCu‐LDH model starts through the reaction between *NO2 and *CO2 intermediates. This spontaneous CN coupling process is beneficial in promoting high levels of urea yield. This work presents a facile approach for preparing 2D ultrathin LDH, showcasing tremendous prospects in electrocatalytic urea synthesis.

Optimization and Kinetics Extraction of Natural Dyes from Henna Leaves (Lawsonia inermis L.) with Ultrasonic Assistance

The Lawson dye contained in the leaves of Lawsonia inermis L. has a red-orange color, which can be used as a fabric dye. The solvent is ethanol because it can attract flavonoid compounds bound to Lawson. The ultrasonic-assisted extraction method is employed to enhance the extraction process by breaking down cell walls, thereby facilitating a more rapid extraction of the desired solute. This study investigated the effects of material-to-solvent ratio, ethanol concentration, and extraction time. The research results were analyzed using a UV-Visible spectrophotometer to determine the yield of Lawson extract. The Face-Centered Composite Design (FCCCD) method was applied to this study to obtain optimal analysis results and extraction conditions. The independent variables in this study were the ratio of ingredients to solvent (0.02-0.06 g/g), ethanol concentration (20-60%), and extraction time (5-15 minutes). The optimal extraction conditions were obtained at a ratio of 0.02 g/g, an ethanol concentration of 60%, and an extraction time of 15 minutes, with a predicted model yield of 15.417%. The actual yield under these conditions was found to be 15.4934%. Furthermore, the extraction kinetics model was analyzed to study and predict the optimal Lawson extraction results. Extraction kinetics calculations were carried out using first-order and second-order based on the Lagergren equation. The most suitable extraction kinetic model is second-order with a determinant coefficient value, or the value of R2 is 1, which indicates that the order kinetic model equation represents the actual conditions.

Modelling of tribological behavior and wear for micro-textured surfaces of Ti2AlNb intermetallic compounds machined with multi-dimensional ultrasonic vibration assistance

Employing multi-dimensional ultrasonic vibration machining (MDUVM), Ti2AlNb intermetallic compounds were processed to generate highly consistent and uniformly arranged micro-texture surfaces. Compared to conventional machining (CM) surfaces, MDUVM surfaces exhibited a noticeable 10.9 % increase in hardness. Sphere-on-disk friction wear tests indicated a noteworthy 15 % reduction in both friction force and coefficient on MDUVM surfaces. The MDUVM surfaces improved contact pressure distribution, reduced oxidation, and facilitated smoother wear debris transition within the wear zone. As a result, the spread of wear into deeper layers was effectively inhibited. An Archard-based predictive model was developed to quantitatively predict wear behavior by incorporating surface micro-texture, confirming the significant influence of surface morphology on frictional wear, which was consistent with experimental findings.

Ultrasonic Vibration-assisted Electrochemical Discharge Machining of Quartz Wafer Micro-Hole Arrays

The micro-hole machining of quartz wafers depends on photolithography techniques akin to those used in semiconductor fabrication. These methods present challenges due to high equipment setup costs, large space requirements, and environmental pollution risks. This research applies ultrasonic vibration assistance in electrochemical discharge machining to create an array of micro-holes on quartz wafers. In the experiments, a self-prepared tungsten carbide micro-electrode array served as the tool electrode. This electrode was a 2 × 2 square array, with needles measuring 30 × 30 μm. A series of experiments was conducted to investigate the effects of various machining parameters, including working voltage, feed rate, duration time, duty factor, and ultrasonic power level, on the characteristics of the micro-hole array. The characteristics included average hole diameter and through-hole surface morphology. The experimental objective was to achieve a through-hole diameter of 80 μm with an accuracy of ±8 μm. During the electrochemical discharge machining, suitable ultrasonic vibrations can thin the insulating gas film coating on the electrode surface, resulting in a more uniform gas film. As the insulating gas film’s thickness decreased, so did the critical voltage needed for the electrochemical discharge machining, reducing the hole’s diameter expansion. The ultrasonic vibration assistance can enable the satisfaction of the dimensional accuracy requirement. The experimental results indicate that ultrasonic vibration assistance can effectively improve the processing capacity and reduce sample fragmentation. A working voltage of 44 V, feed rate of 1 μm/6 s, duration time of 30 μs, duty factor of 30%, and ultrasonic power level of 1 resulted in better inlet and outlet surface morphology without outlet fragmentation. Moreover, the average diameters of the inlet and outlet were roughly 80 μm while meeting the through-hole diameter of 80 μm with accuracy of ±8 μm.

Ultrasonic-assisted extraction, analysis and identification of water extract of propolis

Apis mellifera is one species of bee that produces propolis, a resin-based product. Propolis extraction using ultrasonic assistance is being widely studied. Using water as a solvent is a challenge to capture the bioactive components of propolis. This research aimed to determine the physicochemical quality resulting from the processing of propolis extract from Central Java by ultrasonics using water as a solvent at different temperatures and times. Raw propolis is extracted by the ultrasonic-assisted extraction method at low, medium, and high temperatures. Raw propolis is extracted by the ultrasonic-assisted extraction method at low, medium, and high temperatures. The study used nine treatments with three replications. The extraction time was carried out for 10, 20, and 30 minutes. The study used nine treatments with three replications. The results of the analysis showed that propolis extraction at different temperatures and times had a very significant effect (P<0.01) on the yield, total phenolic content (TPC), and total flavonoid content (TFC), with an average of 6.7–13.3%, 1.10–2.21 mg GAE/mL, and 0.07–0.32 mg QE/mL, respectively. Propolis extraction at different temperatures and times had no significant effect on tannin content, pH, and antioxidant activity. Regarding yield, TPC, TFC, and tannin content values, it was determined that extracting at high temperatures for 30 minutes produced the best results. High temperatures and long timespans are used for the best chance of collecting bioactive components.

Study on the Microstructure and Mechanical Properties of Ultrasonic-Assisted TIG Welded 441 Ferritic Stainless Steel Joints

A self-designed ultrasonic-assisted welding platform was built to improve the poor microstructure and properties of conventional TIG welded ferritic stainless steel. The ultrasonic vibration was transmitted to the weld pool through the base metal in the manner of point–surface contact in the optimal position after calculation. The results show that the coarse columnar grains in the welded joint can be transformed into very fine equiaxed grains under ultrasonic vibration, especially the coarse columnar grains near the fusion line where cliff-like refinement occurs. The maximum grain size in the weld seam is reduced from 420 μm to 260 μm, and the average size is reduced by 60%. At the same time, the grain orientation tends to be harmonized. The microhardness of the welded joint is greatly improved on the whole, and the softening of the heat-affected zone caused by grain coarsening is effectively inhibited. Compared with the welded joints without ultrasonic assistance, the tensile strength and yield strength can be increased by 61 MPa and 47 MPa, respectively, under 130 W ultrasonic vibration. By strengthening the weak part of the welded joint, the weldability and toughness reserve of 441 ferritic stainless steel can be significantly improved.

Effects of ultrasonic-enzymatic-assisted ethanol precipitation method on the physicochemical characteristics, antioxidant and hypoglycemic activities of Tremella fuciformis polysaccharides

This investigation involved the extraction of a novel polysaccharide from the spore fermentation broth of Tremella fuciformis using a method that combined ultrasonic and enzymatic assistance with ethanol precipitation. It was then compared with enzymatic and ultrasonic extraction methods. The objective of this research is to offer a reference point for expanding the application of ultrasonic-assisted enzymatic extraction technology in T. fuciformis polysaccharides (TFPs). Based on single-factor experiments, Box-Behnken was used to optimize the extraction conditions of TFPs by ultrasonic-enzymatic-assisted ethanol precipitation extraction. The results revealed an optimal combination of enzymes, with a cellulase-to-papain ratio of 2:1, an enzyme addition of 4000U/100 mL, an enzymolysis temperature of 49 °C, ultrasonicpower at 3 W/mL and an ultrasonictime of 20 min. The extraction rate of TFPs and α- amylase inhibition rates were 23.94 % and 61.44 %, respectively. Comparing the physicochemical properties, structural characterization and in vitro activity of TFPs extracted through different methods, the results showed that ultrasonic treatment significantly influences the apparent morphology of polysaccharide and could enhance its in vitro biological activity. However, different extraction techniques exhibit insubstantial impact on the chemical composition, glycosidic bonds or glycosidic ring configurations within the polysaccharides. Among them, ultrasonic-enzymatic-assisted ethanol precipitation extraction of polysaccharide has the highest extraction rate and the lowest viscosity. It has significant effects on ABTS+ scavenging activity, α- amylase inhibition rate and glucose dialysis retardation index, polysaccharide treated with ultrasonic-enzymatic showed the best performance. These findings suggest that ultrasonic-enzymatic-assisted ethanol precipitation extraction can enhance the activities of TFPs, thereby providing a valuable insight for their future development and application.

An Experimental Study on Ultrasonic Vibration-Assisted Turning of Aluminum Alloy 6061 with Vegetable Oil-Based Nanofluid Minimum Quantity Lubrication

Minimum quantity lubrication (MQL) is a potential technology for reducing the consumption of cutting fluids in machining processes. However, there is a need for further improvement in its lubrication and cooling properties. Nanofluid MQL (NMQL) and ultrasonic vibration-assisted machining are both effective methods of enhancing MQL. To achieve an optimal result, this work presents a new method of combining nanofluid MQL with ultrasonic vibration assistance in a turning process. Comparative experimental studies were conducted for two types of turning processes of aluminum alloy 6061, including conventional turning (CT) and ultrasonic vibration-assisted turning (UVAT). For each turning process, five types of lubricating methods were applied, including dry, MQL, nanofluid MQL with graphene nanosheets (GN-MQL), nanofluid MQL with diamond nanoparticles (DN-MQL), and nanofluid MQL with a diamond/graphene hybrid (GN+DN-MQL). A specific cutting energy and areal surface roughness were adopted to evaluate the machinability. The results show that the new method can further improve the machining performance by reducing the specific cutting energy and areal surface roughness, compared with the NMQL turning process and UVAT process. The diamond nanoparticles are easy to embed on the workpiece surface under the UVAT process, which can increase the specific cutting energy and Sa as compared to the MQL method. The graphene nanosheets can produce the interlayer shear effect and be squeezed into the workpiece, thus reducing the specific cutting energy. The results provide a new way for the development of eco-friendly machining.

Microstructure and Properties of Magnesium Alloy Joints Bonded by Using Gallium with the Assistance of Ultrasound at Room Temperature

Although magnesium alloys show potential as structural and functional materials, they are difficult to join using traditional welding methods because of their low melting points and active chemical properties. Their poor weldability impedes their universal application. Ultrasound-assisted transient liquid-phase bonding (U-TLP) is a novel method used for magnesium alloy bonding, but in almost all related studies, a heating device has been required, and the types of solders are limited. In this study, gallium was used as solder to bond AZ31 magnesium alloy with ultrasonic assistance at room temperature (without a heating device) due to the low melting temperature of gallium and its compatibility with other metals when forming intermetallic compounds (IMCs). The variations in the products, microstructure, fracture characteristics, and shear strength of the joints were investigated. A reliable joint composed of IMCs (Mg2Ga5, H-MgGa2, and Mg2Ga) and a eutectic structure was obtained after an ultrasonic duration of 3 s. Significantly, the plasticity of the joint was improved due to ultrasonic effects, which included the accelerated element diffusion process, the refinement of grains to nanometer particles, and the homogenization of organization. Thus, the highest shear strength of 14.65 MPa at 4 s was obtained, with obvious cleavage fracture characteristics in the region of the IMCs.

The Ultrasound-Assisted Preparation of Crystal Seeds for the Hydrolysis of TiOSO4 to H2TiO3

The hydrolysis of an industrial titanyl sulfate (TiOSO4) solution to metatitanic acid (H2TiO3) is the crucial step in the production of titanium dioxide (TiO2) using the sulfuric acid process, and the extra-adding seeded route is generally adopted in industry, in which the quality of the crystal seeds plays a critical role. In this study, the optimal process conditions for preparing the crystal seeds via the NaOH neutralization method were first investigated. Then, the ultrasound-assisted preparation of crystal seeds was studied to explore the effect of the ultrasonic time and intensity on the particle size and particle size distribution of crystal seeds. The results demonstrated that ultrasonic assistance is helpful in obtaining crystal seeds with smaller particle sizes and more uniform particle size distribution, and the quality of the hydrolysis product of H2TiO3, i.e., the particle size and its distribution, is strictly correlated with those of the crystal seeds. Under the optimal process conditions for preparing the hydrolytic seeds, the average particle of the hydrolytic seeds prepared without ultrasonic assistance is 25.50 nm. In contrast, the introduction of ultrasonic assistance in the preservation stage could significantly decrease the particle size and narrow the particle size distribution of the hydrolytic seeds. When the ultrasonic time is 4 min and the ultrasonic intensity is 40 W, the average particle of the hydrolytic seeds is decreased to 23.48 nm. Therefore, the quality of the crystal seeds, as well as that of H2TiO3 products, could be significantly improved by introducing ultrasonic assistance with a suitable intensity at a suitable time in the preparation process of crystal seeds via the NaOH neutralization method.

Study on the effects of ultrasonic assistance and external heat dissipation on friction stir welded 7075 aluminum alloy joints

In this paper, conventional friction stir welding (C-FSW), ultrasonic assisted friction stir welding (Ua-FSW) and heat pipe assisted friction stir welding (Ha-FSW) were performed on 4 mm thick 7075 aluminum alloy. The effects of the two different types of assisted technologies on C-FSW were qualitatively compared and analyzed. The microstructure of the joints in the NZ, HAZ and other regions were primarily characterized via SEM-EBSD and TEM, and the strength of the joints were evaluated via the room-temperature tensile properties and microhardness tests. The test results showed that both Ua-FSW and Ha-FSW effectively improved the weld forming, while the surface quality of the joints fabricated by Ha-FSW was better. The acoustic flow effect from ultrasound reduced the temperature gradient, and the heat pipe provided excellent heat dissipation, which well controlled the peak heat and the rate of heat loss throughout FSW, resulting in finer grain sizes after both the Ua-FSW and Ha-FSW processes. EBSD analysis showed that the assistance of two technologies provided a greater effect on TMAZ and HAZ, the stress field generated by ultrasonic vibration favored the formation of subgrains, the heat dissipation of the heat pipe also inhibited the recrystallization, and more subgrains were retained. The assistance of ultrasonic vibration and the heat pipe was mainly in the elongation, especially the joints prepared by the Ha-FSW showed an improvement in elongation by 16.7 % and 33.3 % compared to the Ua-FSW and C-FSW, respectively. This work provides insight into improving welding efficiency and joint performance through modified FSW processes.

The Research on Ultrasonic Vibration Amplitudes in Ti6Al4V DED Additive Manufacturing

Ultrasonic-assisted Ti6Al4V Directed Energy Deposition (DED) additive manufacturing technology can improve the problem of uneven microstructure caused by laser heating and sudden cooling of the molten pool. In this paper, the numerical analysis and experimental verification methods were adopted. The influencing factors, such as the cavitations’ effect, sound flow enhancement effect, and sound flow thermal effect related to the ultrasonic assistance in the molten pool, were analyzed. After equating the energy of the ultrasound, the model of additive manufacturing was introduced in the form of a heat source. The temperature gradient changes during the solidification process of the molten pool with the addition of ultrasound assistance and the effect of ultrasonic vibration during the manufacturing process on its deposited state and microstructure of solution-aged formed parts were studied. The results showed that when the wire feeding rate is 5 mm/s and the laser scanning speed is 5 mm/s, the optimal laser power is 1000 W~1100 W, corresponding to the optimal ultrasonic amplitude of 120 μm. Then, by comparing the temperature field with the same amplitude of 0 μm (i.e., no ultrasonic vibration) and the microstructure of the formed parts, it was verified that ultrasonic vibration facilitates fluid flow in the molten pool, which could lead to a more uniform temperature distribution. This optimized approach not only enhances the understanding of the process but also contributes significantly to the advancement of related research endeavors.

Probe ultrasonication synthesis of Eu2O3-doped 2D WS2 nanosheets for highly selective and sensitive quantification of human catecholamines by fluorescent quenching and shifting

Tungsten disulfide (WS2) nanosheets have been intensively investigated in many fields due to their high crystallinity, outstanding electrochemical properties, and structural integrity. A cutting-edge bottom-up approach with the assistance of probe ultrasonication and annealing was used to synthesize 2D WS2 nanosheets. These nanosheets were modified by probe ultrasonication-assisted doping of Eu2O3 to obtain the reddish-orange color fluorescence with a 68.32% relative quantum yield. This as-synthesized material was used to develop a quenching and shifting associated turn-off turn-on combined type bio-sensor for the detection of human catecholamines. It showed a perfect and wide linear range of 50–800 µM for norepinephrine, epinephrine, and dopamine while the reported detection limits were 0.36 µM, 0.91 µM, and 0.15 µM, respectively. It showed a great recovery of 95% for the human urine sample analysis with spiked analytes. In addition, this could be used as a drug quality assurance option for neurotransmitter drugs.

Hybridization Synthesis and Anticancer Activity Test of New Carboxylic Acid Derivatives by In-Silico and In-Vitro

Design of new compounds as active ingredients of drugs must be selective and efficient to achieve therapeutic efficacy and minimize resulting side effects. Hybridization synthesis approaches using major components of essential oils can reliably generate new molecules that are superior as active ingredients of anti-cancer drugs due to their cytotoxic properties. This study synthesized a hybrid molecule of citronellyl salicylate by an esterification reaction using Steglich and Fisher method under ultrasonic assistance. The Steglich esterification is more efficient in producing citronellyl salicylate during 30 minutes reaction, yield 12.45%. Analysis of the synthesized product by FTIR is characterized by the presence of typical absorptions of the ester group at ῡ 1650 cm-1 and 1270 cm-1, while LC ESI-MS shows m/z 294 is indicated [M+NH4]+. Anticancer activity was tested in-silico for protein receptors MMP-9, MMP-2, Cyclin-A, p53, and BAK using Molecular Docking Pyrx 9.0 and the highest activity was shown binding affinity value -8.4 kcal/mol for the MMP-9 protein receptor. Similarly, the results of the in vitro activity assay of citronellyl salicylate to 4T1 breast cancer cells showed that the morphology of cancer cells was damaged and the viability of cancer cells was lower than that of normal cells

Reducing the cutting tool wear in diamond turning of Zerodur glass-ceramic by the mechanical cleaning effect of ultrasonic vibration assistance

The effects and mechanisms of using ultrasonic vibration assistance (U.V.-assisted machining) combined with straight-nosed cutting tools on reducing the cutting tool wear in single-point diamond turning (SPDT) of Zerodur glass-ceramic are analysed and experimentally investigated. Aiming at the predominant abrasive wear in machining hard and brittle materials, analyses have shown that applying appropriate ultrasonic vibration to the cutting tool can induce considerable inertial acceleration to the wear particles residing on the tool-work interface for promoting their ejection from the contact area to reduce the abrasion. Meanwhile, the high thermal conductivity of diamond can prevent the possible excessive temperature elevation of the cutting tool surface that may result from the in-plane vibration components. To verify these, a longitudinal ultrasonic vibrator that works together with the Poisson's effect was designed for the SPDT processes with straight-nosed cutting tools. Machining tests on Zerodur optics have shown that the assistant ultrasonic vibration is able to decrease the tool flank wearland width by about 30 %, and the groove-like scratches on the tool flank wearland surface were reduced, which is consistent with the analytical deductions. Besides, no significant traces of structural change, element diffusion, and oxidation were found on the worn cutting tool surfaces under either the assisted or unassisted cutting conditions. The experiments have also shown that the enhanced durability of cutting tools has extended the cutting tool life for maintaining good machined surface quality, which is particularly beneficial to the ultra-precision machining of large-size optical parts.

Influence of TiC Particles on Mechanical and Tribological Characteristics of Advanced Aluminium Matrix Composites Fabricated through Ultrasonic-Assisted Stir Casting

The present investigation highlights the development of high-performance materials in the construction materials industry, with a special focus on the production of aluminium matrix composites (AMCs) containing titanium carbide (TiC) particles. The stir casting method with ultrasonic assistance was employed to enhance the mechanical and tribological properties. ASTM standards were employed to evaluate the influence of TiC particles on density, hardness (VHN), ultimate tensile strength (UTS), and wear resistance at various TiC weight fraction percentages (0.0 wt.%, 2.0 wt.%, 4.0 wt.%, 6.0 wt.%, and 8.0 wt.%). Field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analysis were performed to analyse the microstructural changes and elemental phases present in the synthesised composite. Results revealed that the incorporation of 8 wt.% TiC reinforcement in the metal matrix composites demonstrated significant improvements compared to the base alloy. In particular, a substantial enhancement in hardness by 32%, a notable increase of 68% in UTS, and a significant 80% rise in yield strength were observed when contrasted with the pure aluminium alloy. The tensile fracture analysis of the specimens revealed the presence of dimples, voids, and cracks, suggesting a brittle nature. To assess the wear characteristics of the composites, dry sliding wear experiments were performed using a pin-on-disc wear tester. Incorporation of TiC particles resulted in a lower coefficient of friction than the base alloy, with the lowest friction coefficient being recorded at 0.266 for 6 wt.% TiC, according to the data. FESEM and energy-dispersive X-ray spectroscopy (EDXS) were used to examine the surfaces of the worn pin. Overall, the inclusion of TiC reinforcement particles in the matrix alloy greatly enhanced the wear resistance and friction coefficient of the Al-6TiC composites. Ploughing and adhesion under lower loads and delamination under higher loads were the wear mechanisms observed in the wear test.
