Bubbles have been extensively explored as energy carriers ranging from boiling heat transfer and targeted cancer diagnosis. Yet, despite notable progress, the kinetic energy inherent in small bubbles remains difficult to harvest. Here, we develop a transistor-inspired bubble energy generator for directly and efficiently harvesting energy from small bubbles. The key points lie in designing dielectric surface with high-density electric charges and tailored surface wettability as well as transistor-inspired electrode configuration. The synergy between these features facilitates fast bubble spreading and subsequent departure, transforms the initial liquid/solid interface into gas/solid interface under the gating of bubble, and yields an output at least one order of magnitude higher than existing studies. We also show that the output can be further enhanced through rapid bubble collapse at the air/liquid interface and multiple bubbles synchronization. We envision that our design will pave the way for small bubble-based energy harvesting in liquid media.

“…To avoid the interference, we connected the spherical TENG units through seven rectifier bridges respectively. In this way, the energy harvested by the TENG network was not offset . Under the water wave motions, dozens of light‐emitting diodes (LEDs) with a “TENG” pattern can be lighted up by the TENG network, as viewed from Figure e.…”

Ocean waves are one of the most promising renewable energy sources for large-scope applications. Recently, triboelectric nanogenerator (TENG) network has been demonstrated to effectively harvest water wave energy possibly toward large-scale blue energy. However, the absence of effective power management severely restricts the practicability of TENGs. In this work, a hexagonal TENG network consisting of spherical TENG units based on springassisted multilayered structure, integrated with a power management module (PMM), is constructed for harvesting water wave energy. The output performance of the TENG network is found to be determined by water wave frequencies and amplitudes, as well as the wave type. Moreover, with the implemented PMM, the TENG network could output a steady and continuous direct current (DC) voltage on the load resistance, and the stored energy is dramatically improved by up to 96 times for charging a capacitor. The TENG network integrated with the PMM is also applied to effectively power a digital thermo meter and a wireless transmitter. The thermometer can constantly measure the water temperature with the water wave motions, and the transmitter can send signals that enable an alarm to go off once every 10 s. This study extends the application of the power management module in the water wave energy harvesting.

“…A good environment is conducive to sound and rapid economic development. On the contrary, a bad environment will be detrimental to economic development [12][13]. In turn, the high-quality development of the economy is also conducive to the development of the environment, which can provide an economic foundation for environmental governance.…”

Energy is the basis of people's life and the normal operation of economic activities, and plays an important role in our daily life. However, with the rapid economic development(ED), energy problems and ecological environment problems are becoming more and more(MAM) obvious, attracting more and more attention of the society. Problems such as lack of energy, high energy cost but low utilization rate, and environmental pollution have also had a negative impact on people's lives and ED. It is urgent to improve energy efficiency(EE) and reduce pollution. This paper studies the current situation of energy consumption in province A, and uses the super-efficiency(SE) DEA method to measure the total factor energy efficiency(TFEE) of province A, and compares their TFEE values with three cities in province A as representatives space for improvement, and put forward a path for improving TFEE. By improving energy efficiency, it has certain practical significance for promoting the coordinated development of economy and environment.
