Yan Zhang, Fang Xu, Tao Wang, Zhifa Han, more

CNS Neuroscience & Therapeutics > 30 > 7 > n/a - n/a

Background Alzheimer's disease (AD) is the highest risk of COVID‐19 infection, hospitalization, and mortality. However, it remains largely unclear about the link between AD and COVID‐19 outcomes. ACE2 is an entry receptor for SARS‐CoV‐2. Circulating ACE2 is a novel biomarker of death and associated with COVID‐19 outcomes. Methods Here, we explored the shared genetics and causal association between...

Does digital financial inclusion reduce the risk of returning to poverty? Evidence from China

Fang Xu, Xiaoru Zhang, Di Zhou

International Journal of Finance & Economics > 29 > 3 > 2927 - 2949

Digital financial inclusion has become an important way to reduce poverty and prevent poverty return; however, few studies examine the relationship between digital financial inclusion measurement with poverty return governance. Based on data from the 2017 China Household Financial Survey, we construct a digital financial inclusion indicator for micro‐households, and explore its impact on the risk...

Crystallizing Self‐Standing Covalent Organic Framework Membranes for Ultrafast Proton Transport in Flow Batteries

Yulin Wu, Yixing Wang, Dezhu Zhang, Fang Xu, more

Angewandte Chemie International Edition > 62 > 50 > n/a - n/a

Covalent organic frameworks (COFs) display great potential to be assembled into proton conductive membranes for their uniform and controllable pore structure, yet constructing self‐standing COF membrane with high crystallinity to fully exploit their ordered crystalline channels for efficient ionic conduction remains a great challenge. Here, a macromolecular‐mediated crystallization strategy is designed...

Do rural clan‐based networks reduce the risk of a return to poverty? Evidence from China

Fang Xu, Xiaoru Zhang, Di Zhou

Journal of International Development > 35 > 5 > 856 - 883

Avoidance of a return to poverty is a priority within postpoverty alleviation programmes in rural China. As traditional social networks, clan‐based networks have long played a pivotal role within rural society and governance. However, few studies have examined their influence on the return to poverty of rural families. Therefore, we used the China Family Panel Survey (CFPS) data from 2014 to explore...

Improving water transport through sub‐nanometer channels by alternating hydrophilic–hydrophobic patterns

Fang Xu, Linfeng Lei, Cheng Lian, Zhi Xu

AIChE Journal > 69 > 7 > n/a - n/a

Hydrophilicity is key factor to sub‐nanometer channels for water transport. However, how to effectively integrate the respective advantages of hydrophilicity and hydrophobicity to realize ultrafast water transport at the sub‐nanometer scale is still confusing. By using sub‐nanometer channels formed by two‐dimensional covalent organic frameworks as typical models, we herein demonstrate that alternating...

Mechanistic Understanding of Alkali‐Metal‐Ion Effect on Defect State in SrTiO₃ During the Defect Engineering for Boosting Solar Water Splitting

Fan Fang, Zhiyuan Su, Xue Li, Fang Xu, more

Advanced Functional Materials > 33 > 24 > n/a - n/a

Decreasing the Ti³⁺ defect concentration in SrTiO₃ is recognized as the focus of seeking a perfect photocatalytic activity. However, the defect‐engineered SrTiO₃ by doping different low‐valence metal ions have no similarly good activity in overall water spitting, of which the reason has not been determined. Here, Na⁺, K⁺, and Cs are deliberately doped in SrTiO₃ to obtain a close low‐level concentration...

Temperature‐triggered oxidative polymerization for high conductive poly(3,4‐ethylenedioxythiophene) sheets at millimeter scale

Wei Fan, Fang Xu, Kun Gong, Hongfei Lou, more

Journal of Applied Polymer Science > 140 > 26 > n/a - n/a

Poly(3,4‐ethylenedioxythiophene) (PEDOT) is one of the most widely used conductive polymers extensively applied in the electronic components and optoelectronic devices. However, its insolubility and infusibility lead to a complex in situ polymerization process or a sacrificed conductivity in practice. In this paper, we report a facile preparation method of high conductive PEDOT sheets through in situ...

Weiyi Xu, Yixing Wang, Yulin Wu, Fang Xu, more

Advanced Functional Materials > 33 > 21 > n/a - n/a

Ion conductive membranes (ICMs) with robust sub‐2‐nm channels show high proton transport rate in flow battery, but it remains a great challenge to precisely control the ion sieving of the membranes. Herein, as a promising proton‐selective carrier, sulfonated piperazine covalent triazine framework (s‐pCTF) with the channel size of ≈1.5 nm and abundant fast proton hopping sites is introduced into sulfonated...

ZmBET5L1 inhibits primary root growth and decreases osmotic stress tolerance by mediating vesicle aggregation and tethering in maize

Ran Zhao, Nan Li, Qianrun Lin, Manfei Li, more

Plant, Cell & Environment > 46 > 3 > 975 - 990

Improving osmotic stress tolerance is critical to help crops to thrive and maintain high yields in adverse environments. Here, we characterized a core subunit of the transport protein particle (TRAPP) complex, ZmBET5L1, in maize using knowledge‐driven data mining and genome editing. We found that ZmBET5L1 can interact with TRAPP I complex subunits and act as a tethering factor to mediate vesicle aggregation...
