“…27 This work shed light on the noncontact manipulation of liquid marbles coated with nonferromagnetic particles. The trapping and manipulation of small objects can also be achieved via other levitation techniques, such as electrostatic, 28 electromagnetic, 29 and diamagnetic levitation; 30,31 however, these approaches require either that the sample have appropriate electro/magnetic properties or that a powerful magnet be available. 32 In contrast, acoustic levitation is suitable for the processing of a broader range of materials independent of their electro/magnetic properties.…”

Liquid Marble Coalescence and Triggered Microreaction Driven by Acoustic Levitation

Liquid marbles show promising potential for application in the microreactor field. Control of the coalescence between two or among multiple liquid marbles is critical; however, the successful merging of two isolated marbles is difficult because of their mechanically robust particle shells. In this work, the coalescence of multiple liquid marbles was achieved via acoustic levitation. The dynamic behaviors of the liquid marbles were monitored by a high-speed camera. Driven by the sound field, the liquid marbles moved toward each other, collided, and eventually coalesced into a larger single marble. The underlying mechanisms of this process were probed via sound field simulation and acoustic radiation pressure calculation. The results indicated that the pressure gradient on the liquid marble surface favors the formation of a liquid bridge between the liquid marbles, resulting in their coalescence. A preliminary indicator reaction was induced by the coalescence of dual liquid marbles, which suggests that expected chemical reactions can be successfully triggered with multiple reagents contained in isolated liquid marbles via acoustic levitation.

We present the containerless heating process of a deeply undercooled metal droplet by electrostatic levitation. The problem of surface charge loss in the heating process is discussed and specific formulas are given to describe the basic process of charge supplement by the photoelectric and thermoelectric effects. The pure metal zirconium is used to be melted and solidified to analyze the heating process. The temperature-time curve clearly shows the features including melting, undercooling, recalescence and solid-state phase transformation.

“…Therefore, the government or department should seek for efficient ways to help the second mover. The minimal quantum structure was also introduced into the Stackelberg duopoly under different conditions, such as the cases with complete information, [19] discrete distributed incomplete information, [20] and continuous distribution incomplete information, [21,22] respectively. Many interesting results were obtained by the concept of subgame perfect equilibrium and backwards induction.…”

A more efficient model of the quantum Stackelberg duopoly is proposed by using the asymmetric quantization scheme of Qin et al. In this model, two entanglement factors 𝛼 (𝛼 = √︀ 𝛾1/𝛾2) and 𝛾 (𝛾 = √ 𝛾1𝛾2) are introduced, which greatly expands the functions of the previously reported symmetric one. By choosing proper values of 𝛼 and 𝛾, one can better manage the market, such as suppressing the first-mover advantage and enhancing the second-mover profit to avoid abuse of oligopolistic competition, and optimizing the total quantity of the products, so to overcome the deficiencies of "first mover always wins" and "positive quantum entanglement always reduces the total quantity" in the symmetric model. The proposed model here is believed to be a good tool for the government and the department to improve the economic efficiency and develop the market.
