The electro-chemo-mechanical coupling at the solid-liquid interfaces and its applications to electrocatalysis
DENG Qibo, JIA Hanxing, YANG Bo, QI Zhengpan, ZHANG Zheyi, LEE Alamusi, HU Ning
2022, 52(2): 221-252. doi: 10.6052/1000-0992-21-042
Abstract(3360) HTML (1235) PDF(366)
Abstract:
Many advanced catalysts have considered the positive effect of surface mechanics during their design and preparation, in which the high active atoms on the surface are under different strain states. Strain can directly change the bandgap of a metal, which has a significant impact on the electrochemi...
Advances in flexible multibody dynamics of human musculoskeletal systems
GUO Jianqiao, WANG Yanbing, TIAN Qiang, REN Gexue, HU Haiyan
2022, 52(2): 253-310. doi: 10.6052/1000-0992-21-056
Abstract(6744) HTML (2713) PDF(1051)
Abstract:
The human system consists of bones, skeletal muscles, and joints, so the system model in mechanics is a typical flexible multi-body system. The study on musculoskeletal multi-body dynamics mainly aims to determine muscle forces and joint moments together with the effect of their actions during human...
A review on the mechanical stability of flexible perovskite solar cells
ZHANG Meihe, LI Zhihao, LI Honggang, ZHANG Chao
2022, 52(2): 311-338. doi: 10.6052/1000-0992-21-057
Abstract(3502) HTML (1230) PDF(539)
Abstract:
Perovskite solar cells (PSCs) attract great attention from the scientific community due to their low cost, high performance, and rapid increase in photoelectric conversion efficiency (PCE) from 3.8% to 25.5%. Compared with rigid perovskite solar cells, flexible perovskite solar cells (FPSCs) deposit...
Neurological disease and cognitive dynamics (I): Dynamics and control of epileptic seizures
HAN Fang, FAN Denggui, ZHANG Liyuan, WANG Qingyun
2022, 52(2): 339-396. doi: 10.6052/1000-0992-21-064
Abstract(3565) HTML (1033) PDF(425)
Abstract:
Studies have shown that the process of epileptic seizures is closely related to the nonlinear dynamics of the nervous system itself. Therefore, the study of nonlinear network dynamics modeling and regulation of epileptic seizures is helpful in understanding the dynamic mechanism of clinical manifest...

Perfect combination of lightness and ingenuity: secrets in the flight of Paratuposa placentis
ZHANG Xing
2022, 52(2): 410-413. doi: 10.6052/1000-0992-22-011
Abstract(1499) HTML (498) PDF(230)
Abstract:
By using experimental approach, three-dimensional morphological and kinematic models for the flight of Paratuposa placentis are reconstructed. The secrets in the high-performance flight of Paratuposa placentis are successfully unveiled through computational fluid dynamics (CFD) analysis.
