| 1 | Post-Orogenic Tectonic Evolution of the Jiangnan-Xuefeng Orogenic Belt:Insights from Multiple Geochronometric Dating of the Mufushan Massif,South China显示文摘The Mufushan massif, as continental intra-plate magmatites located in the Jiangnan-Xuefeng orogenic belt of the South China. The Mufushan massif constitutes the largest Mesozoic intrusive complex, intruded the Mesoproterozoic Lengjiaxi Formation. Multiple geochronometric dating was used to reconstruct their evolution from emplacement to exhumation. The Mufushan granitoids were emplaced at ~150 Ma(U-Pb zircon) as post-orogenic magmatites contributing to Triassic crustal thickening. Onset of regional extension at ~128 Ma(40Ar/39Ar white mica and biotite) manifests a tectonic regime switch. Intense exhumation prior to ~55 Ma was followed by slow denudation and peneplanation for the next 37 Ma(~55–18 Ma). Accelerated cooling since ~18 Ma may have been caused by a far-field effect of the collision between IndiaAsia Plate or the Pacific-Plate subduction. Through a multi-geochronometric approach, this study provides a new comprehensive model for the cause of the intra-plate magmatism formation in the South China, and also established a reliable geochronological framework of the post-orogenic tectonic evolutions of the Jiangnan-Xuefeng orogenic belt. | Chuanbo Shen Di Hu Kyoungwon Min Chaoqun Yang Xiaowei Zeng Hongyang Fu Xiang Ge | 2020 | Journal of Earth Science2020，31，5： | 4 |
| 2 | Recent active thermal management technologies for the development of energy-optimized aerospace vehicles in China显示文摘Recently, the development of modern vehicles has brought about aggressive integration and miniaturization of on-board electrical and electronic devices. It will lead to exponential growth in both the overall waste heat and heat flux to be dissipated to maintain the devices within a safe temperature range. However, both the total heat sinks aboard and the cooling capacity of currently utilized thermal control strategy are severely limited, which threatens the lifetime of the on-board equipment and even the entire flight system and shrink the vehicle’s flight time and range. Facing these thermal challenges, the USA proposed the program of 'INVENT' to maximize utilities of the available heat sinks and enhance the cooling ability of thermal control strategies. Following the efforts done by the USA researchers, scientists in China fought their ways to develop thermal management technologies for Chinese advanced energy-optimized airplanes and spacecraft. This paper elaborates the available on-board heat sinks and aerospace thermal management systems using both active and passive technologies not confined to the technology in China. Subsequently, active thermal management technologies in China including fuel thermal management system, environment control system, non-fuel liquid cooling strategy are reviewed. At last, space thermal control technologies used in Chinese Space Station and Chang’e-3 and to be used in Chang’e-5 are introduced.Key issues to be solved are also identified, which could facilitate the development of aerospace thermal control techniques across the world. | Jixiang WANG Yunze LI Xiangdong LIU Chaoqun SHEN Hongsheng ZHANG Kai XIONG | 2021 | Chinese Journal of Aeronautics2021，34，2： | 4 |
| 3 | Single lithium-ion channel polymer binder for stabilizing sulfur cathodes显示文摘Lithium-sulfur batteries have great potential for high-performance energy-storage devices,yet the severe diffusion of soluble polysulfide to electrolyte greatly limits their practical applications.To address the above issues;herein we design and synthesize a novel polymer binder with single lithium-ion channels allowing fast lithium-ion transport while blocking the shuttle of unnecessary polysulfide anions.In situ UV-vis spectroscopy measurements reveal that the prepared polymer binder has effective immobilization to polysulfide intermediates.As expected,the resultant sulfur cathode achieves an excellent specific capacity of 1310 mAh g^-1 at 0.2 C,high Coulombic efficiency of 99.5%at 0.5 C after 100 cycles and stable cycling performance for 300 cycles at 1 C(1 C=1675 mAg^-1).This study reports a new avenue to assemble a polymer binder with a single lithium-ion channel for solving the serious problem of energy attenuation of lithium-sulfur batteries. | Chaoqun Niu Jie Liu Tao Qian Xiaowei Shen Jinqiu Zhou Chenglin Yan | 2020 | National Science Review2020，7，2： | 3 |
| 4 | Genomic and Phenotypic Diversity of Carbapenemase-Producing Enterobacteriaceae Isolates from Bacteremia in China: A Multicenter Epidemiological, Microbiological, and Genetic Study显示文摘Carbapenemase-producing Enterobacteriaceae(CPE) isolates are recognized as one of the most severe threats to public health. However, the population structure and genetic characteristics of CPE isolates among bloodstream infections(BSIs) are largely unknown. To address this knowledge gap, in this study,we included patients with clinically significant BSIs due to Enterobacterales isolates, recruited from 26 sentinel hospitals in China(2014–2015). CPE isolates were microbiologically and genomically characterized,including their susceptibility profiles, molecular typing, phylogenetic features, and genetic context analysis of carbapenemase-encoding genes. Of the 2569 BSI Enterobacterales isolates enrolled, 42(1.6%) were carbapenemase-positive. Moreover, among the 2242 investigated isolates, 1111(49.6%) extendedspectrum β-lactamase(ESBL)-producing isolates were identified in Escherichia coli(E. coli), Klebsiella pneumoniae(K. pneumoniae), Proteus mirabilis(P. mirabilis), and Klebsiella oxytoca. Whole genome sequencing analysis showed the clonal spread of K. pneumoniae carbapenemase(KPC)-2-producing K. pneumoniae sequence type(ST) 11 and New Delhi metallo-β-lactamase(NDM)-5-producing E. coli ST167 in our collection. Plasmid analysis revealed that carbapenemase-encoding genes were located on multiple plasmids. A high prevalence of biofilm-encoding type 3 fimbriae clusters and yesiniabactin-associated genes was observed in K. pneumoniae isolates. This work demonstrates the high prevalence of ESBLs and the wide dissemination of CPE among BSI isolates in China, which represent real clinical threats. Moreover, our findings first illustrate a more comprehensive genome scenario of CPE isolates among BSIs. The clonal spread of KPC-2-producing K. pneumoniae ST11 and NDM-5-producing E. coli ST167 needs to be closely monitored. | Beiwen Zheng Hao Xu Lihua Guo Xiao Yu Jinru Ji Chaoqun Ying Yunbo Chen Ping Shen Huiming Han Chen Huang Shuntian Zhang Tao Lv Yonghong Xiao | 2022 | Engineering2022，8，5： | 2 |

| 6 | A self-activated NO-releasing hydrogel depot for photothermal enhanced sterilization显示文摘The ascendant danger of bacterial infections has resulted in an urgent requirement for developing new antibacterial approaches.Recently,nitric oxide(NO)has shown a broad-spectrum antimicrobial activity while avoiding resistance.However,achieving effective NO-based antibacterial therapies remains challenging,mired by the safety concerns of NO donor,residual toxicity by the ingredients,or complicated procedures.Herein,a self-activated NO-releasing hydrogel depot is fabricated by Ca^(2+)-crosslinked sodium alginate doped with CaO_(2)nanoparticles,L-arginine,and oxidized mesoporous carbon nanoparticles(OMCN)for photothermal enhanced bacteria killing.The locally concentrated H_(2)O_(2),generated from the reaction of CaO_(2)nanoparticles and water,could oxidize L-arginine to release NO.Meanwhile,benefiting from the remarkable photothermal effect of OMCN,the hybrid hydrogel possesses a synergistic sterilization behavior in combating both Gram-negative Escherichia coli and Grampositive Staphylococcus aureus bacteria in vitro.Moreover,the dual therapeutic hydrogel displays high efficiency in treatment of bacteria-infected mice with back wound model while showing no distinct toxicity.In addition,the restricted environment of hydrogel makes it easy to remove all the components from the infected wound,alleviating possible side effects from exogenous H_(2)O_(2).As such,the designed NO-synergistic photothermal hydrogel provides a promising strategy for treating bacterial infections. | Shen Zhang Kelei Guan Yaoxin Zhang Junqing Zhang Hongyu Fu Ting Wu Dilan Ouyang Chaoqun Liu Qiang Wu Zhaowei Chen | 2023 | Nano Research2023，16，4： | 0 |
| 7 | Barley FASCIATED EAR genes determine inflorescence meristem size and yield traits显示文摘In flowering plants,the inflorescence meristem(IM)provides founder cells to form successive floral meristems,which are precursors of fruits and seeds.The activity and developmental progression of IM are thus critical for yield production in seed crops.In some cereals,such as rice(Oryza sativa)and maize(Zea mays),the size of undifferentiated IM,which is located at the inflorescence apex,is positively associated with yield traits such as spikelet number.However,the relationship between IM size and yieldrelated spike traits remains unknown in the Triticeae tribe.Here we report that IM size has a negative correlation with yield traits in barley(Hordeum vulgare).Three FASCIATED EAR(FEA)orthologs,HvFEA2,HvFEA3,and HvFEA4,regulate IM size and spike morphogenesis and ultimately affect yield traits.Three HvFEAs genes are highly expressed in developing spikes,and all three loss-of-function mutants exhibit enlarged IM size,shortened spikes,and reduced spikelet number,which may lead to reduced grain yield.Natural variations identified in HvFEAs indicate selection events during barley domestication.We further reveal that HvFEA4,as a transcription factor,potentially targets multiple pathways during reproductive development,including transcriptional control,phytohormone signaling,and redox status.The roles of barley FEA genes in limiting IM size and promoting spikelet formation suggest the potential of increasing yield by manipulating IM activity. | Chengyu Wang Xiujunan Yang Yueya Zhang Chaoqun Shen Jin Shi Chongjing Xia Taohong Fang Qiang Tu Ling Li Xinli Zhou Dabing Zhang Gang Li | 2023 | The Crop Journal2023，11，3： | 0 |
| 8 | Analysis of volatile organic compounds in exhaled breath after radiotherapy显示文摘Radiotherapy uses high-energy X-rays or other particles to destroy cancer cells and medical practitioners have used this approach extensively for cancer treatment(Hachadorian et al.,2020).However,it is accompanied by risks because it seriously harms normal cells while killing cancer cells.The side effects can lower cancer patients’quality of life and are very unpredictable due to individual differences(Bentzen,2006). | Dianlong GE Xue ZOU Yajing CHU Jijuan ZHOU Wei XU Yue LIU Qiangling ZHANG Yan LU Lei XIA Aiyue LI Chaoqun HUANG Pei WANG Chengyin SHEN Yannan CHU | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，2： | 0 |
| 9 | BS_(0.5)BNT-based relaxor ferroelectric ceramic/glass-ceramic composites for energy storage显示文摘Relaxor ferroelectric ceramics have very high dielectric constant(e)but relatively low electrical breakdown strength(Eb),while glass-ceramics exhibit higher E,due to the more uniformly dispersed amorphous phases and submicrocrystals/nanocrystals inside.How to effectively combine the advantages of both relaxor ferroelectric ceramics and glass-ceramics is of great significance for the development of new dielectric materials with high energy storage performance.In this work,we firstly prepared BaO-SrO-Bi_(2)O_(3)-Na_(2)0-TiO_(2)-Al_(2)O_(3)-SiO_(2)(abbreviated as GS)glass powders,and then fabricated(Ba_(0.3)Sr_(0.7))_(0.5)(Bi_(0.5)Na_(0.5))_(0.5)TiO_(3)+x wt%GS ceramic composites(abbreviated as BSo.sBNT-xGS,x=0,2,6,10,14,16,and 18).Submicrocrystals/nanocrystals with a similar composition to BSo.sBNT were crystalized from the glass,ensuring the formation of uniform core-shell structure in BSo.sBNT-xGS relaxor ferroelectric ceramic/glass-ceramic composites.When the addition amount of GS was 14 wt%,the composite possessed both high&r(>3200 at 1 kHz)and high E,(~170 kV/cm)at room temperature,and their recoverable energy storage density and efficiency were Wrec=2.1 J/cm’and n=65.2%,respectively.The BSo.sBNT-14GS composite also had several attractive properties such as good temperature,frequency,cycle stability,and fast charge-discharge speed.This work provides insights into the relaxor ceramic/glass-ceramic composites for pulsed power capacitors and sheds light on the utilization of the hybrid systems. | Xuhai Shi Kai Li Zong-Yang Shen Junqi Liu Chaoqun Chen Xiaojun Zeng Bo Zhang Fusheng Song Wenqin Luo Zhumei Wang Yueming Li | 2023 | Journal of Advanced Ceramics2023，12，4： | 0 |
