Efficacy and safety of sacubitril/valsartan on postoperative atrial fibrillation in adult patients undergoing cardiac surgery: a real-world observational study

Autor: Xiaodong Chen, Pengxin Liu, Fengzheng Zhu, Dong Wang, Sumin Yang, Wenlong Yan

Publikováno v: Frontiers in Cardiovascular Medicine, Vol 11 (2024)

BackgroundThe mechanism underlying new-onset postoperative atrial fibrillation (POAF) in adult cardiac surgery is not well understood. However, efficient pharmacological methods to prevent and treat arrhythmic complications are still lacking. In the

Investigation on the generation and propagation mechanism of triple-point structures on rotating detonation front

Autor: Pengxin Liu, Hongmin Su, Qilong Guo, Dong Sun, Chen Li

Publikováno v: AIP Advances, Vol 13, Iss 5, Pp 055225-055225-10 (2023)

Based on the Navier–Stokes equation with chemical reaction kinetics, rotating detonation waves are numerically simulated using premixed reactants H2/air at a stoichiometric ratio. The triple-point structure on the detonation front is captured. The

Atomic overlayer of permeable microporous cuprous oxide on palladium promotes hydrogenation catalysis

Autor: Kunlong Liu, Lizhi Jiang, Wugen Huang, Guozhen Zhu, Yue-Jiao Zhang, Chaofa Xu, Ruixuan Qin, Pengxin Liu, Chengyi Hu, Jingjuan Wang, Jian-Feng Li, Fan Yang, Gang Fu, Nanfeng Zheng

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-8 (2022)

It remains a challenge to fabricate metal catalysts with interfacial active sites distributed on the whole two-dimensional (2D) surface of metal nanoparticles. Here the authors demonstrate that the overgrowth of atomic-thick porous Cu2O on Pd readily

A decomposition formula for the wall heat flux of a compressible boundary layer

Autor: Dong Sun, Qilong Guo, Xianxu Yuan, Haoyuan Zhang, Chen Li, Pengxin Liu

Publikováno v: Advances in Aerodynamics, Vol 3, Iss 1, Pp 1-13 (2021)

Abstract Understanding the generation mechanism of the heat flux is essential for the design of hypersonic vehicles. We proposed a novel formula to decompose the heat flux coefficient into the contributions of different terms by integrating the conse

Interfacing with silica boosts the catalysis of copper

Autor: Chaofa Xu, Guangxu Chen, Yun Zhao, Pengxin Liu, Xinping Duan, Lin Gu, Gang Fu, Youzhu Yuan, Nanfeng Zheng

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-10 (2018)

Metal-support interaction plays an important role in heterogeneous catalysis, but silica has been rarely reported as an effective support to create active metal-support interfaces for promoting catalytic reactions. Here, the authors discover that Cu/

Carbon Monoxide Promotes the Catalytic Hydrogenation on Metal Cluster Catalysts

Autor: Ruixuan Qin, Pei Wang, Pengxin Liu, Shiguang Mo, Yue Gong, Liting Ren, Chaofa Xu, Kunlong Liu, Lin Gu, Gang Fu, Nanfeng Zheng

Publikováno v: Research, Vol 2020 (2020)

Size effect plays a crucial role in catalytic hydrogenation. The highly dispersed ultrasmall clusters with a limited number of metal atoms are one candidate of the next generation catalysts that bridge the single-atom metal catalysts and metal nanopa
