    The flywheel energy storage system (FESS) is an ideal candidate for electrical energy savings in subway systems when combined with regenerative braking technology. Practical application in a subway system requires a FESS with large energy storage capacity (ESC), high power level, short recharge interval times, and high recharge cycles. The high-T c superconductive (HTS) Maglev bearing can levitate and rotate a heavy rotor stably at a high speed, which can improve the performance of a FESS in subway systems dramatically. The authors designed a FESS prototype based on an HTS Maglev bearing, with a maximal power level of 100 kW and a maximal ESC of 5 kWh. This paper introduces the design and manufacturing process of this FESS prototype, including the major components such as the HTS Maglev bearing, the permanent-magnet synchronous motor, the composite flywheel rotor, and so on. The conclusions of this paper are useful for the design and application of HTS Maglev FESSs.

    In this brief, a CMOS image sensor that exploits the possibility of reconfiguring pixel photodiodes for energy harvesting for wireless image sensor applications is proposed. Based on the logarithmic sensor architecture, each pixel photodiode of the proposed sensor array can be configured into either photosensing or energy-harvesting element to accomplish image-capturing or energy-harvesting purpose, respectively. An addressing scheme for reduced resolution readout and improved energy-harvesting efficiency, and a two-level quantization scheme for reduced readout dynamic power consumption are also proposed.

    As people's demands for the environment and future development, new energy sources such as wind energy, and solar energy have become the trend of the times. At the same time, due to the introduction of clean energy, power electronics and switching devices in the power system are heavily invested in the power network. The investment in areas above has made the stability of the power system suffering more tests, and the instability and oscillation of the power system have intensified. Therefore, this paper first analyzes the mathematical model of power system oscillation. The existing oscillation causes and suppression methods of traditional power systems are summarized. Then the causes of the micro-grid oscillation of the distributed power supply with high permeability are analyzed in detail. The difference from the traditional power system oscillation is that the traditional power network oscillation is caused by the shafting torsional vibration of the rotating electrical machine. The vibration reacts, which may cause the damping torque of the unit in the corresponding torsional vibration mode to weaken or even become negative, causing oscillation. Or rotary electric machines (including synchronous/asynchronous power generation/motors) and power electronic converters may exhibit an "induction generator/negative resistance" effect on the electrical oscillation mode under certain operating conditions, when the negative resistance exceeds the total positive resistance of the grid, resulting in The LC oscillates and diverge. The reason for the power electronic oscillation is the coupling oscillation between the power electronic converters or the network generated by the interaction with the AC grid. This kind of oscillation is difficult to find the existing fixed model to apply, because the power electronic device has a fast response speed and low Inertia, unlike traditional motors, oscillations are more likely to occur in high frequency bands and have more features. Based on this, different research methods and speculations on the causes of microgrid oscillations at home and abroad are summarized. Due to different causes, the methods used to suppress system oscillations are summarized and described. Finally, the content of the full text is summarized. Prospects for the future development of microgrid oscillation research.

    Abstract Since the mercury ions are particularly toxic and they can cause severe harmful effects even at low concentration, searching for selective and sensitive probe to detect Hg2+ is of considerable significance. In this study, Rhodamine-naphthalimide conjugate (NRT) has been developed as a novel lysosome-targeted ratiometric Hg2+ probe. NRT exhibited colorimetric and dual-channel turn-on fluorescence responses toward Hg2+ and could be used to quantify the ion spiked in river water samples. Besides, the probe could also selectively stain lysosomes and sensitively visualize mercury ions in living cells by dual-channel imaging.

    Due to the increasing penetration of wind power, the fluctuation and forecasting error have posed significant challenges to dispatchers for secure and economic operation of the power system concerned. This paper proposes a model for attaining a robust solution to the security-constrained unit commitment (SCUC) problems based on scenarios. Different from most robust optimization models, the model in this paper guarantees a robust solution with the optimal confidence level, and some measures such as wind power curtailment and load shed are considered. The proposed model provides theoretical basis to help operators strike a balance between economic performance and robustness. The proposed model is solved by Benders decomposition. The effectiveness of the proposed model is verified by results of numerical cases on the modified IEEE 39, 118-bus system.

    In order to rapidly diagnose and locate the fault, we present ICARSFD (Information entropy-based Clustering Algorithm for Rapid Software Fault Diagnosis). In this paper, the average entropy and the total entropy are defined to guide the clustering operation over fault modes. This algorithm firstly stores the related information of existing faults in the form of fault tree, and deems each fault as an initial cluster. By calculating the information entropy between clusters and comparing them with the average entropy and the total entropy, fault clustering is completed. For the faults inappropriate to their located clusters, we take a retrospective approach to cluster them. Thereby the clustering effect related with the fault order could be addressed. Secondly, according to the ascending order of information entropy, the fault to be analyzed is matched to each cluster. Lastly, both the fault diagnosis results and fault paths are put out. In addition, if the fault match isn't successful, the fault path will be identified through fault tree, and the clustering results will be updated later. The experimental results demonstrate that ICARSFD has both good clustering effect and detection effect.

    A method to determine simultaneously the magnetostrictive coefficient and the elastic properties (Young’s modulus and Poisson ratio) of a thin film during the growth was developed based on minimization of the total elastic energy of a cantilever film-substrate system. Compared to other published measurement methods, an inaccuracy in the magnetostrictive coefficient, caused by assuming the elastic properties of the film as those of the bulk material, could be avoided. Only one elastic isotropic substrate is employed in the present method. The experimental data of an Fe-based amorphous thin film was analyzed using the model. The calculated dependence of the magnetostrictive coefficient on the external magnetic field was compared with the experiment, and the discrepancy between both results is explained. Furthermore, the elastic properties of the film were also obtained.

    It is well known that transition metal oxides (TMOs) have attracted extensive attention as promising anodes for next-generation lithium ion batteries (LIBs) owing to their low cost and high theoretical capacities. However, the huge volume changes upon lithiation/delithiation cycling gradually cause drastic particle pulverization in the electrodes, thus leading to fast capacity fading and limiting their practical applications. High-entropy oxides with enhanced electronic conductivity and multiple electrochemically active elements display stepwise lithium storage behaviors, thus efficiently alleviating the volume change induced electrode pulverization problem. Herein, we report the synthesis of a new kind of spinel (Mg0.2Ti0.2Zn0.2Cu0.2Fe0.2)3O4 material via a facile one-step solid state reaction method and subsequent high-energy ball-milling. When used as anodes for LIBs, the submicrometer-sized (Mg0.2Ti0.2Zn0.2Cu0.2Fe0.2)3O4 particles exhibit superior lithium storage properties, delivering a large reversible capacity of 504 mA h g−1 at a current density of 100 mA g−1 after 300 cycles, and notably an exceptional rate capacity of 272 mA h g−1 at 2000 mA g−1. Our work highlights that rational design of high-entropy oxides with different electrochemically active elements and novel structures might be a useful strategy for exploring high-performance LIB anode materials in next-generation energy storage devices.

    The flywheel energy storage system (FESS) is an ideal candidate for electrical energy savings in subway systems when combined with regenerative braking technology. Practical application in a subway system requires a FESS with large energy storage capacity (ESC), high power level, short recharge interval times, and high recharge cycles. The high-T c superconductive (HTS) Maglev bearing can levitate and rotate a heavy rotor stably at a high speed, which can improve the performance of a FESS in subway systems dramatically. The authors designed a FESS prototype based on an HTS Maglev bearing, with a maximal power level of 100 kW and a maximal ESC of 5 kWh. This paper introduces the design and manufacturing process of this FESS prototype, including the major components such as the HTS Maglev bearing, the permanent-magnet synchronous motor, the composite flywheel rotor, and so on. The conclusions of this paper are useful for the design and application of HTS Maglev FESSs.

Based on the logarithmic sensor architecture, each pixel photodiode of the proposed sensor array can be configured into either photosensing or energy-harvesting element to accomplish image-capturing or energy-harvesting purpose, respectively. An addressing scheme for reduced resolution readout and improved energy-harvesting efficiency, and a two-level quantization scheme for reduced readout dynamic power consumption are also proposed.

    As people's demands for the environment and future development, new energy sources such as wind energy, and solar energy have become the trend of the times. At the same time, due to the introduction of clean energy, power electronics and switching devices in the power system are heavily invested in the power network. The investment in areas above has made the stability of the power system suffering more tests, and the instability and oscillation of the power system have intensified. Therefore, this paper first analyzes the mathematical model of power system oscillation. The existing oscillation causes and suppression methods of traditional power systems are summarized. Then the causes of the micro-grid oscillation of the distributed power supply with high permeability are analyzed in detail. The difference from the traditional power system oscillation is that the traditional power network oscillation is caused by the shafting torsional vibration of the rotating electrical machine. The vibration reacts, which may cause the damping torque of the unit in the corresponding torsional vibration mode to weaken or even become negative, causing oscillation. Or rotary electric machines (including synchronous/asynchronous power generation/motors) and power electronic converters may exhibit an "induction generator/negative resistance" effect on the electrical oscillation mode under certain operating conditions, when the negative resistance exceeds the total positive resistance of the grid, resulting in The LC oscillates and diverge. The reason for the power electronic oscillation is the coupling oscillation between the power electronic converters or the network generated by the interaction with the AC grid. This kind of oscillation is difficult to find the existing fixed model to apply, because the power electronic device has a fast response speed and low Inertia, unlike traditional motors, oscillations are more likely to occur in high frequency bands and have more features. Based on this, different research methods and speculations on the causes of microgrid oscillations at home and abroad are summarized. Due to different causes, the methods used to suppress system oscillations are summarized and described. Finally, the content of the full text is summarized. Prospects for the future development of microgrid oscillation research.

    Abstract Since the mercury ions are particularly toxic and they can cause severe harmful effects even at low concentration, searching for selective and sensitive probe to detect Hg2+ is of considerable significance. In this study, Rhodamine-naphthalimide conjugate (NRT) has been developed as a novel lysosome-targeted ratiometric Hg2+ probe. NRT exhibited colorimetric and dual-channel turn-on fluorescence responses toward Hg2+ and could be used to quantify the ion spiked in river water samples. Besides, the probe could also selectively stain lysosomes and sensitively visualize mercury ions in living cells by dual-channel imaging.

    Due to the increasing penetration of wind power, the fluctuation and forecasting error have posed significant challenges to dispatchers for secure and economic operation of the power system concerned. This paper proposes a model for attaining a robust solution to the security-constrained unit commitment (SCUC) problems based on scenarios. Different from most robust optimization models, the model in this paper guarantees a robust solution with the optimal confidence level, and some measures such as wind power curtailment and load shed are considered. The proposed model provides theoretical basis to help operators strike a balance between economic performance and robustness. The proposed model is solved by Benders decomposition. The effectiveness of the proposed model is verified by results of numerical cases on the modified IEEE 39, 118-bus system.
