Research Progress of Shear Thickening Electrolyte Based on Liquid–Solid Conversion Mechanism

Batteries (2023)

Qianqian Huang Xin Liang Bing Liu Huaxia Deng

As an essential component of the lithium-ion battery system, electrolyte plays a crucial role in ion transport between the electrodes. In the event of thermal runaway, commercial organic electrolytes are prone to internal disturbances and fires; hence, research on safe electrolytes has gradually become a hot topic during recent years. Shear thickening electrolyte, as a new type of smart electrolyte, can exhibit a liquid state in the absence of external force and rapidly converts to a quasi-solid state once the battery is subjected to drastic impact loading. In this paper, the recent progress of shear thickening electrolytes with liquid–solid switching performance is presented, including its working principles, synthesis and preparation procedure, and battery performance. Additionally, the perspective and challenges for practical application are discussed.

PIN Diodes Array Made of Perovskite Single Crystal for X‐Ray Imaging

physica status solidi (RRL) - Rapid Research Letters (2018)

Xin Wang Dewei Zhao Yunping Qiu Yin Huang Yao Wu

Recently, lead (Pb) halide hybrid perovskites have emerged as sensitive X‐ray detectors due to their desirable charge transport properties and high absorption of ionizing photons. This work reports on a facile methodology for fabrication of highly efficient X‐ray PIN diodes based on MAPbBr 3 (MA, methylammonium; Pb, lead; Br, bromide) single crystals to detect X‐ray energies ranging from 30 to 100 keV. The 2 mm thickness PIN diode exhibits a low dark current density of 20 nA cm −2 at 150 V cm −1 and high X‐ray sensitivity of 23.6 μC mGy air −1 cm −2 . Besides, a large‐area array based on 30 mm × 28 mm × 7 mm MAPbBr 3 single crystal is fabricated for X‐ray imaging. When augmented with signal processing, selective higher and lower energy X‐ray signals can be separated simultaneously to satisfy different requirements for soft and hard organs and tissues in one exposure. This approach offers a new pathway for a one‐time radiation dose applied to the human body to achieve X‐ray images for tissues and blood vessels concurrently.

The shape parameters of coal and gangue particles derived from 3D scanning

Scientific Data (2023)

Daolong Yang Jinjing Tang Ningning Hu Youtao Xia Yanting Yu

Abstract The irregular shape of mineral particles directly affects the angle of repose, bulk density and flow-properties, and the interaction behaviour between the particles and a contact surface. This paper presents a dataset of spatial data and shape parameters collected from 37 gangue particles and 135 anthracite coal particles, which come from the Shangzhuang Coal Mine. The particle surface models were obtained by a Wiiboox white light raster 3D scanner and Reeyee software. To obtain the scanning surface, each particle was scanned 8 times in different axial rotation directions. The final scanning model was obtained by stacking two scanning surfaces, and the shape parameters, such as length ratio, flatness ratio, and Zingg index, were obtained. This dataset is particularly useful for researchers and engineers who want to investigate the shape of coal and gangue particles or who want to test or benchmark measurement methods concerning the three-dimensional morphology of particles.

Multistage Condition-Based Resilient Maintenance Scheduling for Power Systems During Ice Storms

IEEE Transactions on Industry Applications (2023)

Tao Niu Qianqian Huang Sidun Fang Guanhong Chen Ruijin Liao

Power systems with high penetration of renewables are vulnerable to the ice storm disasters which frequently happen in recent years, leading to dramatic large-scale power outages. It is necessary for the system operators to develop reasonable maintenance strategies when facing ice storm environments to improve the operational reliability and security. However, different from other disasters like typhoon and earthquake, ice storms last for longer period and the system operates under time-varying conditions, and the conventional resilient maintenance scheduling with fixed schemes are not suitable to be used. To address this problem, a multistage condition-based resilient maintenance scheduling method is proposed in this paper to minimize maintenance costs, fault costs, and power loss while considering the time-varying states of equipment. An emergency maintenance strategy based on maintenance threshold decision rule is proposed in response to the varying equipment states. Finally, the optimization model is solved with the IPOPT solver, and an IEEE RTS-79 system is used to demonstrate the validity of the proposed method.
