| 1 | Recent progress on MOF-derived carbon materials for energy storage显示文摘Metal-organic frameworks(MOFs)are of quite a significance in the field of inorganic-organic hybrid crystals.Especially,MOFs have attracted increasing attention in recent years due to their large specific surface area,desirable electrical conductivity,controllable porosity,tunable geometric structure,and excellent thermal/chemical stability.Some recent studies have shown that carbon materials prepared by MOFs as precursors can retain the privileged structure of MOFs,such as large specific surface area and porous structure and,in contrast,realize in situ doping with heteroatoms(eg,N,S,P,and B).Moreover,by selecting appropriate MOF precursors,the composition and morphology of the carbon products can be easily adjusted.These remarkable structural advantages enable the great potential of MOF-derived carbon as high-performance energy materials,which to date have been applied in the fields of energy storage and conversion systems.In this review,we summarize the latest advances in MOF-derived carbon materials for energy storage applications.We first introduce the compositions,structures,and synthesis methods of MOF-derived carbon materials,and then discuss their applications and potentials in energy storage systems,including rechargeable lithium/sodium-ion batteries,lithium-sulfur batteries,supercapacitors,and so forth,in detail.Finally,we put forward our own perspectives on the future development of MOF-derived carbon materials. | Jincan Ren Yalan Huang He Zhu Binghao Zhang Hekang Zhu Shenghui Shen Guoqiang Tan Feng Wu Hao He Si Lan Xinhui Xia Qi Liu | 2020 | Carbon Energy2020，2，2： | 8 |
| 2 | Loss of Wip1 aggravates brain injury after ischaemia/reperfusion by overactivating microglia显示文摘Background and purpose The inflammatory response mediated by microglia/macrophages is closely related to cerebral ischaemia/reperfusion injury.Wild-type p53-induced protein phosphatase 1(Wip1),a serine/threonine phosphatase,is expressed in various tissues.A growing number of reports have suggested that Wip1 is a negative regulator of inflammation in peripheral tissue;however,its role in the central nervous system(CNS)remains unclear.This study aimed to clarify whether Wip1 can inhibit CNS inflammation by regulating microglia/macrophage functions after ischaemic injury.Methods A model of middle cerebral artery occlusion and reperfusion was established in mice.CNS inflammation was simulated by lipopolysaccharide treatment of primary microglia.Laser speckle imaging was used to monitor regional cerebral blood flow.Behavioural outcomes were assessed with a TreadScan gait analysis system.TTC staining was used to evaluate the infarct volume,and western blotting and immunofluorescence staining were applied to detect the phenotypical transformation of microglia.ELISA was performed to detect the levels of inflammatory factors.Results Wip1 expression was increased after ischaemia/reperfusion.Wip1-knockout(KO)mice displayed more severe brain injury than wild-type mice,as indicated by aggravated motor dysfunction,greater brain infarct volumes and higher expression of inflammatory cytokines(interleukin-6 and tumour necrosis factor alpha)in the brain.We also found that Wip1 depletion increased microglial/macrophage activation in both in vitro and in vivo models,which all showed activation of microglia/macrophages.Lentivirus-Ppm1d reversed the injury induced by Wip1-KO.Conclusions Our results suggest that Wip1 may inhibit neuroinflammation by inhibiting microglial/macrophage activation after brain ischaemia/reperfusion injury. | Feng Yan Xiang Cheng Ming Zhao Shenghui Gong Ying Han Liping Ding Di Wu Yumin Luo Wei Zuo Lingling Zhu Ming Fan Xunming Ji | 2021 | Stroke & Vascular Neurology2021，6，3： | 4 |
| 3 | Reconstruction of the western Pacific warm pool SST since 1644 AD and its relation to precipitation over East China显示文摘Based on coral proxies we reconstructed the western Pacific warm pool sea surface temperature (SST) since 1644 AD. High-frequency reconstructions are based on eight high-pass filtered coral series and raw reconstructions are derived from eight unfiltered coral series, respectively. Validation and comparison with other SST/temperature series show that the reconstructed warm pool SST is highly reliable. The leading periods of warm pool SST are ~2.1, ~2.3, ~2.9, ~3.6, ~3.8, and 80.7-year during the last ~360 years. The warm pool SST exhibits some obvious long-term trends: an upward trend of 0.04℃ per century for the period of 1644―1825, while a decreasing trend of 0.24℃ per century for the period of 1826―1885, and then a remarkable warming trend of 0.28℃ per century taking place between 1886 and 2006. Especially, the SST shows the strongest trend of 0.67℃ increase per century during the last 50 years, a warming unprecedented since 1644 AD. On interannual timescale, the connections between ENSO and the warm pool SST are robust during the reconstruction period. There are significant corre- lations between the warm pool SST and summer precipitation of the Yellow River basin and Huaihe River basin; the correlation coefficients are -0.44 in reconstruction period (1880―1949 AD) and -0.46 in instrumental period (1950―2005 AD) respectively. This relationship is also found between flooddrought index and the warm pool SST during the past 360 years, and their correlation coefficients are -0.20 in reconstruction period and-0.46 in instrumental period respectively, significant at the 0.01 level. On interdecadal timescale, this connection is more robust, and the correlation coefficient of the low-pass filtered components is -0.42 during the whole period (1644―2000 AD). When the warm pool is warmer than normal, the precipitation is usually below the normal in the Yellow River and Huaihe River basin. On the contrary, when the warm pool is colder than the normal, there may be more precipitation. The reconstructed warm pool SSTs provide useful information and reference for further research on climate change mechanism in East China. | ZHANG ZiYin GONG DaoYi HE XueZhao GUO Dong FENG ShengHui | 2009 | Science China Earth Sciences2009，52，9： | 3 |
| 4 | Is oral microbiome of children able to maintain resistance and functional stability in response to short-term interference of ingesta?显示文摘Dear Editor,A series of studies had focused on the ecological stability of human microbiome(Lozupone et al.,2012;Faith et al.,2013;Moya and Ferrer,2016).Despite the continuous perturbation and the highly personalized composition within the human microbiome(Human Microbiome Project,2012),healthy adults stably maintain their microbial communities in terms of space and time(Faith et al.,2013;Moya and Ferrer,2016;Oh et al.,2016).This stability is proved to be critical for the well-being of human body(Lozupone et al.,2012).On the contrary,major shifts in microbial community composition are often related to diseases(Lynch and Pedersen,2016). | Fangqiao Wei Xiangyu Sun Yufeng Gao Haoyu Dou Yang Liu Lili Su Haofei Luo Ce Zhu Qian Zhang Peiyuan Tong Wen Ren Zhe Xun Ruochun Guo Yuanlin Guan Shenghui Li Yijun Qi Junjie Qin Feng Chen Shuguo Zheng | 2021 | Protein & Cell2021，12，6： | 1 |

| 7 | Study on the Sediment Transport Flux and Mechanism in the Bohai Strait at the Tidal and Monthly Scales in Summer显示文摘Based on the data of tidal currents and suspended sediment concentrations observed synchronously at 11 stations in the Bohai Strait lasting for 25 hours,the temporal and spatial variations of currents and suspended sediment concentrations in the Bohai Strait in summer were analyzed.The Study preliminarily discussed the transport mechanism,transport trend and transport flux of suspended sediments in summer,using flux-mechanism decomposition method and numerical simulation.The suspended sediment transport was mainly controlled by advection and next influenced by vertical net circulation,while resuspension is relatively weak in Bohai Strait.The single-width fluxes of investigation stations varied from 3.8 to 89.1 gm^(−1) s^(−1),with the maximum value in Miaodao Strait.The suspended sediment transport trends in Laotieshan channel along the vertical section are obviously distinct.The waters mainly flow out of the Bohai Sea in surface layer,while into the Bohai Sea in bottom layer.However,the transport trends of other channels in the centre and south are consistent vertically.The sediments in the Bohai Strait follows the transport pattern of moving outward from the south and inward from the north in summer,i.e.,the sediments are carried out of the Bohai Sea through the Laotieshan channel,while into the Bohai Sea through other channels.And the outflow flux exceeds the inflow flux in August with the net water flux of 1.4×10^(10)m^(3),basically same as the deliveries of the rivers into the Bohai Sea.Moreover,the suspended sediment flux is 0.33 Mt under the action of tidal residual currents in the Yellow Sea in August. | YUAN Xiaodong FENG Xiuli HU Rijun JIANG Shenghui ZHONG Wei | 2023 | Journal of Ocean University of China2023，22，1： | 0 |
| 8 | A reference-guided TILLING by amplicon-sequencing platform supports forward and reverse genetics in barley显示文摘Barley is a diploid species with a genome smaller than those of other members of the Triticeae tribe,making it an attractive model for genetic studies in Triticeae crops.The recent development of barley genomics has created a need for a high-throughput platform to identify genetically uniform mutants for gene function investigations.In this study,we report an ethyl methanesulfonate(EMS)-mutagenized population consisting of 8525M_(3) lines in the barley landrace“Hatiexi”(HTX),which we complement with a high-quality de novo assembly of a reference genome for this genotype.The mutation rate within the population ranged from 1.51 to 4.09 mutations per megabase,depending on the treatment dosage of EMS and the mutation discrimination platform used for genotype analysis.We implemented a three-dimensional DNA pooling strategy combined with multiplexed amplicon sequencing to create a highly efficient and cost-effective TILLING(targeting induced locus lesion in genomes)platform in barley.Mutations were successfully identified from 72 mixed amplicons within a DNA pool containing 64 individual mutants and from 56 mixed amplicons within a pool containing 144 individuals.We discovered abundant allelic mutants for dozens of genes,including the barley Green Revolution contributor gene Brassinosteroid insensitive 1(BRI1).As a proof of concept,we rapidly determined the causal gene responsible for a chlorotic mutant by following the MutMap strategy,demonstrating the value of this resource to support forward and reverse genetic studies in barley. | Congcong Jiang Miaomiao Lei Yu Guo Guangqi Gao Lijie Shi Yanlong Jin Yu Cai Axel Himmelbach Shenghui Zhou Qiang He Xuefeng Yao Jinhong Kan Georg Haberer Fengying Duan Lihui Li Jun Liu Jing Zhang Manuel Spannagl Chunming Liu Nils Stein Zongyun Feng Martin Mascher Ping Yang | 2022 | Plant Communications2022，3，4： | 0 |
| 9 | Kinetics of Catalyzed Thermal Degradation of Polylactide and Its Application as Sacrificial Templates显示文摘Polylactide(PLA)is an outstanding sacrificial template material for the manufacture of microchannels in a thermosetting matrix.However,the initial thermal degradation temperature of pure PLA is relatively high(about 280℃),which limits its use as a sacrificial template.In this report,we found that TBD,an organic base catalyst,can significantly reduce the thermal degradation temperature of PLA.TBD has higher catalytic activity for the thermal degradation of PLA compared with Tin(II)oxalate(Sn(Oxa)),one catalyst reported in the literature.Moreover,the gaseous products catalyzed by TBD for PLA thermal degradation are mainly lactide,and the formation temperature of the monomer is lower and the yield is higher,which may have potential value for PLA recycling.A combined catalyst,S8T2,was composed of 80%low activity catalyst Sn(Oxa)and 20%high activity catalyst TBD,which can catalyze the rapid degradation of PLA without greatly damaging the mechanical properties of PLA.PLA-S8T2 sacrificial fibers can form high-precision one-dimensional microchannels in the epoxy resin matrix,and 3D-printed PLA-S8T2 sacrificial templates can be used to form three-dimensional microchannels in a thermosetting matrix by vaporization of sacrificial components process(VaSC).These features highlight the great potential of PLA-S8T2 as sacrificial template material for the preparation of the complicated microchannels in the thermosetting matrix. | Li Feng Chenhui Cui Zhen Li Mengyuan Zhang Shenghui Gao Qiang Zhang Youshen Wu Zhishen Ge Yilong Cheng Yanfeng Zhang | 2022 | Chinese Journal of Chemistry2022，40，23： | 0 |
| 10 | Lower activity time constraint on the ore-controlling Erdaogou fault in the Qingchengzi orefield of the Liaodong Peninsula,NE China显示文摘The Erdaogou fault,also known as the 101 fault,comprises the most important NE strike component in the ore-controlling system in the Qingchengzi orefield,Liaodong Peninsula.Due to the poor outcrop conditions in the field,the Erdaogou fault lacks activity time constraint.We demonstrate the constraint activity time of the fault since we observe a lamprophyre that was cut through by the Erdaogou fault in the Taoyuan area,central to the Qingchengzi orefield.Zircon grains from the lamprophyre dyke exhibit typical oscillatory zoning and yield weighted mean U–Pb age of 223.8±1.1 Ma(MSWD=1.5).The lower activity time limit of the Erdaogou fault is thus first constrained as 224 Ma or so and is correlated with the crystallization age of the Xinling and Shuangdinggou plutons within the orefield.Taking previous mineralization studies into consideration,a Triassic tectonic-magmatism-mineralization model is approved in the Qingchengzi orefield. | Yan Zhao Yuewen Feng Peng Zhang Linlin Kou Zhongzhu Yang Shenghui Li Wei Wang | 2022 | Acta Geochimica2022，41，2： | 0 |
