Researches have investigated the formation, transportation and spreading of bubble on solid surface with specific wettability. However, bubble transfer on wettability-heterogeneous surfaces has been rarely reported, which also plays significant role in water electrolysis, heat transfer, micro-bubble collection, *** this work, we carefully investigate the behavior of bubble transfer from the aerophobic or aerophilic region to the superaerophilic region through fabricating the wettability-heterogenous surfaces. Surface energy was elucidated to be transformed to the kinetic energy during bubble transfer process. Theoretical analysis on the average velocity of bubble transfer was consistent with the experimental *** influence of wettability of solid substrate, bubble volume and superaerophilic stripe width on bubble transfer are carefully investigated. Moreover, wettability-heterogeneous surfaces were explored to be applied in micro-CO_(2) bubble collection and H_(2) bubble removement in water splitting.

利用腐植酸(HA)与具有较强电容性的纳米Fe_(3)O_(4)颗粒形成的金属化合物(HA@Fe_(3)O_(4))修饰微生物燃料电池(MFC)阳极,探究含有以17α-乙炔基雌二醇(EE2)为代表性类固醇雌激素(SEs)的模拟废水在MFC阳极的降解特性,并对EE2降解过程中MFC的产电特性进行了表征。电化学交流阻抗测试结果表明,与不存在HA@Fe_(3)O_(4)的MFC相比,存在HA@Fe_(3)O_(4)的MFC的欧姆阻抗降低了79.58%,电荷转移阻抗降低了89.60%。循环伏安扫描结果显示,HA@Fe_(3)O_(4)的存在显著增加了阳极板的电容。HA@Fe_(3)O_(4)修饰阳极后MFC最大功率密度可达537.37 mW/m~2。HA@Fe_(3)O_(4)修饰的阳极可显著提高MFC对EE2的去除率,EE2在低浓度下(≤5.0μmol/L)可以介导电子转移,提高MFC的产电性能,进而提高MFC去除EE2的能力,但高浓度(5.0~10.0μmol/L)时会抑制微生物的活性并降低MFC产电效率。

We proposed and experimentally demonstrated a simple and novel photonic spiking neuron based on a distributed feedback(DFB) laser subject to side-mode optical pulse injection(SMOPI). The DFB laser chip is designed and fabricated based on asymmetric equivalent π phase shift(π-EPS) with the reconstruction-equivalent-chirp(REC) technique. Under side-mode continuous-wave(CW) optical injection,excitability pulse was experimentally observed during the dominant mode switching process due to the injection-locked effect. Based on the transition between the excitability regime and the side-mode injection locking effect, the controllable and repeatable neuron-like spiking response can be realized when external stimulus pulses are electro-optically modulated on the CW optical carrier. The experimental results show that the spike threshold, temporal integration, and refractory period, which are important spike processing mechanisms in biological neurons, can all be achieved in the optically-injected DFB laser. The experimental findings are also verified numerically with a rate equation model that considers the SMOPI. To the best of our knowledge, this is the first experimental demonstration of a photonic spiking neuron based on a DFB laser subject to SMOPI, which holds promise for realizing large-scale photonic spiking neuron arrays for hardware photonic spiking neural network chips.
