“…Research showed that the HP treatment enhanced van der Waals interaction by reducing the C–C bond lengths, which led to molecular aggregation ( 34 , 35 ). The molecular aggregation reduced the surface tension of the liquid ( 36 , 37 ), thus enhancing the volatilization ( 38 , 39 ).…”

IntroductionThe flavor deterioration blocks the development of melon juice.MethodsThe effects of ultra-high temperature (UHT) and high pressure (HP) treatments on the aromatic compound concentrations of melon juice and their mechanisms were explored with fresh juice as the control.ResultsA total of 57 volatile compounds were identified by gas chromatography-tandem mass spectrometry analysis. β-ionone was shown to be the major aromatic component of melon juice for the first time. The HP at 200 MPa for 20 min increased the total volatile concentration of melon juice by 1.54 and 3.77 times the control and UHT, respectively. Moreover, the sum concentration of a major aromatic component in the HP treatment was 1.49 and 5.94 times higher than that of the control and UHT, respectively.DiscussionThe HP treatment raised the concentration of volatile and aromatic components of melon juice by reducing their surface tension.

“…However, the relative advantage between micro-/nano-bubbles and bubbles + ultrasound is not definite. This may be attributed to the fact that ultrasound can produce cavitation bubbles [31,32], but can also kill initial gas bubbles, producing a degassing effect. After the oil-droplet-borne bubbles rupture via ultrasound, the detached oil droplets are likely to stick again to the plastic surfaces [33][34][35].…”

3D printing technology has been used to directly produce various actual products, ranging from engines and medicines to toys, especially due to its advantage in producing items of complicated, porous structures, which are inherently difficult to clean. Here, we apply micro-/nano-bubble technology to the removal of oil contaminants from 3D-printed polymeric products. Micro-/nano-bubbles show promise in the enhancement of cleaning performance with or without ultrasound, which is attributed to their large specific surface area enhancing the adhesion sites of contaminants, and their high Zeta potential which attracts contaminant particles. Additionally, bubbles produce tiny jets and shock waves at their rupture, driven by coupled ultrasound, which can remove sticky contaminants from 3D-printed products. As an effective, efficient, and environmentally friendly cleaning method, micro-/nano-bubbles can be used in a range of applications.

“…Micro-nano bubbles were introduced by ultrasonic cavitation after the composite particles were melted. So novel composite electrospun films were prepared by adding inorganic scattering particles [52,53] with micro-nano bubbles [54][55][56][57][58][59] (Figure 9b). The cooling performance of the films was enhanced after a series of experiments, simulations, and process optimization.…”

Global climate change has become a major environmental threat and development challenge facing humanity. Controllable nuclear fusion is a globally recognized ideal solution for clean energy, but its required high-energy triggering conditions and intense energy release prevent existing technologies from achieving safe, stable, and long-term continuous operation. Here, inspired by the traditional Chinese firecrackers, we propose a pulsed fusion reaction flywheel energy storage multi-reactor relay operation to drive the steam turbine to continuously and stably generate electricity for a long period of time; meanwhile, to install cleaning rotors in the cooling medium pipeline to enhance heat exchange, and to apply radiative cooling technology on the surface of the cooling tower to improve cooling efficiency and to reduce energy consumption, thereby improving system safety and overall energy efficiency. Proposing the combination of original technologies at both the hot end and the cold end of the system, we strive to open up a new way for controllable nuclear fusion power generation.
