The Co3O4 electrode is a very promising material owing to its ultrahigh capacitance. Nevertheless, the electrochemical performance of Co3O4-based supercapacitors practically confined by limited active sites and poor conductivity Co3O4. Herein, we provide facile synthetic strategy tightly anchoring nanosheets carbon fiber conductive cloth (Co3O4@C) using zeolitic imidazolate framework-67 (ZIF-67) sacrificial template via in situ impregnation pyrolysis method. Benefiting from enhancement...
BiFeO 3 /ZnO heterostructures, with a strongly enhanced piezocatalytic dye decomposition performance, offer promising option to treat wastewater through collecting environmental vibration energy.
A square cylinder with a V-shaped groove on the windward side in piezoelectric cantilever flow-induced vibration energy harvester (FIVEH) is presented to improve output power of and reduce critical velocity system, aiming at self-powered supply low consumption devices natural environment wind speed. Seven groups galloping harvesters (GPEHs) were designed tested tunnel by gradually changing angle two symmetrical sharp angles V-groove. The GPEH 45° was selected as optimal harvester. Its 61%...
Due to the advantages of high specific capacity, various temperatures, and low cost, layered LiNi 0.6 Co 0.2 Mn O 2 has become one potential cathode materials for lithium-ion battery. However, its application was limited by cation mixing degree poor electric conductivity. In this paper, influences synthesis methods modification such surface coating doping on electrochemical properties as cycle stability, rate capability, impedance are reviewed discussed. The confronting issues have been...
In field, the earth pressure on a retaining wall is common effect of kinds factors. To figure out how key factors act, it has taken into account arching effects together with contribution from mode displacement to calculate in proposed method. Based Mohr circle, conversion factor introduced determine shear stresses between artificial slices soil mass. light this basis, modified differential solution presented for calculation active wall. Comparisons show that result method identical...
In this work, we propose a wideband quintuple-well potential piezoelectric-based vibration energy harvester using combined nonlinearity: the magnetic nonlinearity induced by force and piecewise-linearity produced mechanical impact. With extra stable states compared to other multi-stable harvesters, quin-stable can distribute its more uniformly, which provides shallower wells results in lower excitation threshold for interwell motion. The mathematical model of is derived equivalent...
Piezoelectric materials can harvest tiny mechanical energy existing in the environment, and have strong ability to convert signals into electrical signals. Piezo-electro-chemical coupling be realized via combining piezoelectric effect of with electrochemical redox effect. In recent years, piezo-electro-chemical has attracted a lot attention from researchers harvesting vibration treat dye wastewater. The catalyst material dispersed solution is deformed by ultrasonic vibrations. Owing...
In order to make a piezoelectric vibration energy harvester collect more on broader frequency range, nonlinearity is introduced into the system, allowing produce multiple steady states and deflecting response curve. However, can easily maintain intra-well motion rather than inter-well motion, which seriously affects its efficiency. The aim of this paper analyze how take full advantage nonlinear characteristics widen bandwidth obtain energy. influence inter-permanent magnet torque bending...
