Solid-state intramolecular motions in continuous fibers driven by ambient humidity for fluorescent sensors

Jiang, Yunmeng; Cheng, Yanhua; Liu, Shunjie; Zhang, Haoke; Zheng, Xiaoyan;

2020 National Science Review

doi:10.1093/nsr/nwaa135 pmid:34691610

Abstract One striking feature of molecular rotors is their ability to change conformation with detectable optical signals through molecular motion when stimulated. However, due to the strong intermolecular interactions, synthetic molecular rotors have often relied on fluid environments. Here, we...

ENSO and Southeast Asian biomass burning modulate subtropical trans-Pacific ozone transport

Xue, Lian; Ding, Aijun; Cooper, Owen; Huang, Xin; Wang, Wuke;

2020 National Science Review

doi:10.1093/nsr/nwaa132 pmid:34691654

Abstract Trans-Pacific transport of enhanced ozone plumes has been mainly attributed to fossil fuel combustion in Asia in spring, but less attention has been paid to vegetation fires in Asia. Here we show that the El Niño-Southern Oscillation (ENSO)-modulated fires in Southeast Asia, rather than...

Iron in the NEEM ice core relative to Asian loess records over the last glacial–interglacial cycle

Xiao, Cunde; Du, Zhiheng; Handley, Mike J; Mayewski, Paul A; Cao, Junji;

2020 National Science Review

doi:10.1093/nsr/nwaa144 pmid:34691679

Abstract Mineral dust can indirectly affect the climate by supplying bioavailable iron (Fe) to the ocean. Here, we present the records of dissolved Fe (DFe) and total Fe (TDFe) in North Greenland Eemian Ice Drilling (NEEM) ice core over the past 110 kyr BP. The Fe records are significantly...

A fast and versatile cross-linking strategy via o-phthalaldehyde condensation for mechanically strengthened and functional hydrogels

Zhang, Zhen; He, Chaoliang; Rong, Yan; Ren, Hui; Wang, Tianran;

2020 National Science Review

doi:10.1093/nsr/nwaa128 pmid:34691609

Abstract Fast and catalyst-free cross-linking strategy is of great significance for construction of covalently cross-linked hydrogels. Here, we report the condensation reaction between o-phthalaldehyde (OPA) and N-nucleophiles (primary amine, hydrazide and aminooxy) for hydrogel formation for the...

Integrating climate, biodiversity, and sustainable land-use strategies: innovations from China

Schmidt-Traub, Guido; Locke, Harvey; Gao, Jixi; Ouyang, Zhiyun; Adams, Justin;

2020 National Science Review

doi:10.1093/nsr/nwaa139 pmid:34691678

To reverse the accelerating degradation of biodiversity and ecosystem services (‘nature’) and climate [1,2], the Convention on Biological Diversity (CBD) and the UN Framework Convention on Climate Change (UNFCCC) will hold major meetings in 2021. We argue that, as a critical priority, countries...

Unleash electron transfer in C–H functionalization by mesoporous carbon-supported palladium interstitial catalysts

Zhao, Xiaorui; Cao, Yueqiang; Duan, Linlin; Yang, Ruoou; Jiang, Zheng;

2020 National Science Review

doi:10.1093/nsr/nwaa126 pmid:34691608

Abstract The functionalization of otherwise unreactive C–H bonds adds a new dimension to synthetic chemistry, yielding useful molecules for a range of applications. Arylation has emerged as an increasingly viable strategy for functionalization of heteroarenes which constitute an important class...
