“…In case ''A'' (E L = 7 mJ) 80% of the bubbles are not longer detected after t = 3 ms, consistent with the size estimation performed using a different probing method in ref. 29 but under the same laser beam configuration. In this previous study, approximately 150 bubbles were observed within the same ROI, with typical radius below 100 nm.…”

“…This stands in contrast to the method described in ref. 29, which requires several hundred measurements taken under highly controlled conditions and is therefore not suitable for non-repetitive phenomena. Additionally, the previously mentioned method relies on a strong interaction of the nanobubbles with a bi-polar pressure wave for cavity detection.…”

“…In the present work, we explore the capabilities of high-speed ultrasound imaging for studying rapid flows and deformations commonly observed in bubbly liquids and soft materials. Specifically, we have utilized USI in these three distinct scenarios: (1) bubble jetting near the free surface of a liquid pool; 27 (2) dissolution of sub-micron laser-induced gas bubbles; 28,29 and (3) the propagation of shear waves in a soft material, namely industrial gelatin. 22,[30][31][32]…”

“…In the tense global energy situation today, countries around the world are seeking new energy alternative strategies, and clean energy has become the focus of attention due to its advantages of continuous supply and security. However, clean energy has low energy density and is easily affected by objective factors, such as climate and location, which limits its effective use [1][2][3][4][5][6][7][8]. However, with the continuous development of the IoT and new energy utilization technology, the comprehensive utilization of clean energy has been brought into full play, and the energy management and monitoring mode has also undergone fundamental changes [9][10][11][12][13][14][15].…”

With the continuous development of the Internet of Things (IoT) and new energy utilization technology, the energy management and monitoring mode has undergone fundamental changes. Design and development of remote real-time monitoring and management system for multi-energy heat collection has certain theoretical and practical application value. The existing remote temperature control model fully considers neither the impact of multi-energy collaborative heat collection on remote temperature control strategy, nor the interactions among multiple objective factors, such as climate and location. Therefore, this paper studied the remote temperature control strategy of multienergy heat collection based on the IoT. First, the paper gave the application architecture of multi-energy heat collection system functions, and developed a multi-energy heat collection system model without simulation performance loss using stochastic modeling ideas. Second, this paper made full use of the error information of the process, thus correcting the predicted value of the remote temperature control output. Finally, the experimental results verified the effectiveness of the model and the control strategy.

“…2022); it required a combination of localised heating and a Lamb wave propagating in a very thin liquid gap. In the work of Rosselló & Ohl (2021, 2023), the on-demand production of bulk nano-bubbles through the passage of an intense laser pulse in water was demonstrated. Transient bubbles appear within the region exposed to light once a rarefaction wave passes through, attaining temporal and spatial control of the bulk nano-bubble nucleation.…”

The maximum size and lifetime of an acoustically nucleated cavitation bubble is inversely proportional to the driving frequency and has achieved a limit of approximately 10 MHz. Smaller cavitation bubbles that are critical to microscopic applications require shorter lifetimes that correspond to higher oscillation frequencies. Here, we demonstrate that acoustic cavitation in the 100 MHz range and beyond can be achieved through wave propagation in a solid rather than in a liquid. The cavitation bubble is nucleated at a nano-sized fracture on a glass substrate, and its expansion is driven by a leaky Rayleigh wave, while the inertial collapse is induced by a trailing shock wave. As both waves travel at different velocities, the time interval between these two events is a function of the distance to the source. In this way, we demonstrate experimentally control of the lifetime of the bubbles in a range between 6 and 80 ns, corresponding to oscillation frequencies between 13 and 166 MHz. Our results agree with finite-volume fluid–structure interaction simulations.
