| 1 | Highly stable lead-free Cs3Bi2I9 perovskite nanoplates for photodetection applications显示文摘Lead halide perovskites have received tremendous attentions recently for their excellent properties such as high light absorption coefficient and long charge carrier diffusion length. However, the stability issues and the existence of toxic lead cations have largely limited their applications in optoelectronic area. Herein, we report the synthesis and investigation of highly stable and lead-free Cs3Bi2I9 perovskite nanoplates for visible light photodetection applications. The Cs3Bi2I9 nanoplates were synthesized through a facile solution-processed method, which is also applicable to various substrates. The achieved nanoplates present very good crystal quality and exhibit excellent long-term stability even exposed in moist air for several months. Photodetectors were constructed based on these high-quality perovskite nanoplates for the first time, and display a maximum photoresponsivity of 33.1 mA/W under the illumination of 450 nm laser, which is six times higher than the solution-synthesized CH3NH3PbI3 nanowire photodetectors. The specific detectivity of these devices can reach up to 10^10 Jones. Additionally, the devices exhibit fast rise and decay time of 10.2 and 37.2 ms, respectively, and highly stable photoswitching behavior with their photoresponse well retaining under alternating light and darkness. This work opens up a new opportunity for stable and low-toxic perovskite-based optoelectronic applications. | Zhaoyang Qi Xianwei Fu Tiefeng Yang Dong Li Peng Fan Honglai Li Feng Jiang Lihui Li Ziyu Luo Xiujuan Zhuang Anlian Pan | 2019 | Nano Research2019，12，8： | 7 |

| 3 | Early assessment of the safety and immunogenicity of a third dose(booster)of COVID-19 immunization in Chinese adults显示文摘Inducing durable and effective immunity against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)via vaccination is essential to combat the current pandemic of coronavirus disease 2019(COVID-19).It has been noticed that the strength of anti-COVID-19 vaccination-induced immunity fades over time,which calls for an additional vaccination regime,as known as booster immunization,to restore immunity among previously vaccinated populations.Here we report a pilot open-label trial of a third dose of BBIBP-CorV,an inactivated SARS-CoV-2 vaccine(Vero cell),on 136 participants aged between 18 to 63 years.Safety and immunogenicity in terms of neutralizing antibody titers and cytokine/chemokine responses were analyzed as the main endpoint until day 28.While systemic reactogenicity was either absent or mild,SARS-CoV-2-specific neutralizing antibody titers rapidly arose in all participants within 4 weeks,surpassing the peak antibody titers elicited by the initial two-dose immunization regime.Broad increases of cellular immunity-associated cytokines and chemokines were also detected in the majority of participants after the third vaccination.Furthermore,in an exploratory study,a newly developed recombinant protein vaccine,NVSI-06-08(CHO Cells),was found to be safe and even more effective than BBIBP-CorV in eliciting humoral immune responses in BBIBP-CorV-primed individuals.Together,these results indicate that a third immunization schedule with either homologous or heterologous vaccine showed favorable safety profiles and restored potent SARS-CoV-2-specific immunity,providing support for further trials of booster vaccination in larger populations. | Yuntao Zhang Yunkai Yang Niu Qiao Xuewei Wang Ling Ding Xiujuan Zhu Yu Liang Zibo Han Feng Liu Xinxin Zhang Xiaoming Yang | 2022 | Frontiers of Medicine2022，16，1： | 3 |
| 4 | Reduction of Low-grade Manganese Dioxide Ore Pellets by Biomass Wheat Stalk显示文摘An investigation on reducing low-grade manganese dioxide ore pellets was carried out by using wheat stalk as reductant. The main impact factors of reduction percent such as particle size, biomass/ore ratio, heating rate, nitrogen flow rate, temperature and time in reduction process were discussed. The morphology and component of manganese dioxide ore particle at different stages were also analyzed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The results show the increase of the reduction temperature and time, biomass/ore ratio, and the decrease of particle size, heating rate and nitrogen flow rate can significantly enhance reduction efficiency. The reduction kinetic of the manganese ore is controlled by three-dimensional mass diffusion of gaseous reductive volatiles passing from the surface to the core of the ore particles. The activation energy E and frequency factor A were calculated to be 24.15 kJ · mol-1 and 166 min-1 , respectively. Biomass pyrolysis volatiles adsorbed onto the surface of the ore particle leads to serious variation of the microstructures and chemical composition of the manganese ore particles. | Honglei ZHANG Guocai ZHU Hong YAN Yuna ZHAO Tiancheng LI Xiujuan FENG | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，2： | 3 |
| 5 | Effects of cannabinoid receptor type 2 on endogenous myocardial regeneration by activating cardiac progenitor cells in mouse infarcted heart显示文摘Cannabinoid receptor type 2(CB2)activation is recently reported to promote proliferation of some types of resident stem cells(e.g.,hematopoietic stem/progenitor cell or neural progenitor cell).Resident cardiac progenitor cell(CPC)activation and proliferation are crucial for endogenous cardiac regeneration and cardiac repair after myocardial infarction(MI).This study aims to explore the role and possible mechanisms of CB2receptor activation in enhancing myocardial repair.Our results revealed that CB2receptor agonist AM1241 can significantly increase CPCs by c-kit and Runx1 staining in ischemic myocardium as well as improve cardiomyocyte proliferation.AM1241 also decreased serum levels of MDA,TNF-αand IL-6 after MI.In addition,AM1241 can ameliorate left ventricular ejection fraction and fractional shortening,and reduce fibrosis.Moreover,AM1241 treatment markedly increased p-Akt and HO-1 expression,and promoted Nrf-2 nuclear translocation.However,PI3K inhibitor wortmannin eliminated these cardioprotective roles of AM1241.In conclusion,AM1241 could induce myocardial regeneration and improve cardiac function,which might be associated with PI3K/Akt/Nrf2 signaling pathway activation.Our findings may provide a promising strategy for cardiac endogenous regeneration after MI. | WANG YaBin MA Sai WANG Qiang HU WenXing WANG DongJuan LI XiuJuan SU Tao QIN Xing ZHANG XiaoTian MA Ke CHEN JiangWei XIONG LiZe CAO Feng | 2014 | Science China(Life Sciences)2014，57，2： | 3 |
| 6 | CRISPR/Cas9-mediated mutagenesis at microhomologous regions of human mitochondrial genome显示文摘Genetic manipulation of mitochondrial DNA(mtDNA)could be harnessed for deciphering the gene function of mitochondria;it also acts as a promising approach for the therapeutic correction of pathogenic mutation in mtDNA.However,there is still a lack of direct evidence showing the edited mutagenesis within human mtDNA by clustered regularly interspaced short palindromic repeats-associated protein 9(CRISPR/Cas9).Here,using engineered CRISPR/Cas9,we observed numerous insertion/deletion(InDel)events at several mtDNA microhomologous regions,which were triggered specifically by double-strand break(DSB)lesions within mtDNA.InDel mutagenesis was significantly improved by sgRNA multiplexing and a DSB repair inhibitor,iniparib,demonstrating the evidence of rewiring DSB repair status to manipulate mtDNA using CRISPR/Cas9.These findings would provide novel insights into mtDNA mutagenesis and mitochondrial gene therapy for diseases involving pathogenic mtDNA. | Bang Wang Xiujuan Lv Yufei Wang Zhibo Wang Qi Liu Bin Lu Yong Liu Feng Gu | 2021 | Science China(Life Sciences)2021，64，9： | 3 |
| 7 | Porosity Distribution Characteristics and Geological Analysis of Brine Storage Medium in the Qaidam Basin, Western China显示文摘Underground brine is an unusual water resource that contains abundant mineral resources. It is distributed widely in the Qaidam Basin, western China, a hyperarid inland basin located in the northern Tibetan Plateau. Pores in the brine storage medium act as storage space and transmission channels of underground brine. Therefore, the porosity of brine storage medium determines its ability to store brine. In this study, Mahai Salt Lake was used as the research area as a modern saline lake located in the north area of the Qaidam Basin. A total of 100 porosity samples were collected from eight sampling points in two profiles of the research area at sampling depths of 1.30–314.78 m. The porosity distribution characteristics and influencing factors in brine storage medium were analysed according to the measured porosity data. Based on analysis of the pore structure characteristics, the brine storage medium contains intercrystalline pores, unlike conventional freshwater storage mediums. Moreover, the primary salt rock is susceptible to dissolution by lighter brine, facilitating the formation of secondary porosity. Due to the formation of secondary pores, a porosity greater than 20% remains even at buried depths greater than 100 m. Based on the geological statistical analysis, due to the geographic location, salt formation time, and depositional environment, the porosity values of Mahai Salt Lake do not exhibit a wider distribution, but also show more extreme values than a nearby salt lake. Based on the porosity characteristics by depth, due to the presence of secondary pores, flooding, stratigraphic static pressure, and other factors, porosity shows fluctuations with increasing depth. | HU Shuya XIAO Changlai LIANG Xiujuan ZHAO Quansheng WANG Guangcai ZHANG Jianwei FENG Juan | 2018 | Chinese Geographical Science2018，28，4： | 2 |
| 8 | Lithium bis(oxalate)borate crosslinked polymer electrolytes for high-performance lithium batteries显示文摘Solid electrolytes play a vital role in solid-state Li secondary batteries,which are promising high-energy storage devices for new-generation electric vehicles.Nevertheless,obtaining a suitable solid electrolyte by a simple and residue-free preparation process,resulting in a stable interface between electrolyte and electrode,is still a great challenge for practical applications.Herein,we report a self-crosslinked polymer electrolyte(SCPE)for high-performance lithium batteries,prepared by a one-step method based on 3-methoxysilyl-terminated polypropylene glycol(SPPG,a liquid oligomer).It is worth noting that lithium bis(oxalate)borate(Li BOB)can react with SPPG to form a crosslinked structure via a curing reaction.This self-formed polymer electrolyte exhibits excellent properties,including high roomtemperature ionic conductivity(2.6×10^(-4) S cm^(-1)),wide electrochemical window(4.7 V),and high Li ion transference number(0.65).The excellent cycling stability(500 cycles,83%)further highlights the improved interfacial stability after the in situ formation of SCPE on the electrode surface.Moreover,this self-formation strategy enhances the safety of the battery under mechanical deformation.Therefore,the present self-crosslinked polymer electrolyte shows great potential for applications in high-performance lithium batteries. | Xiao Wang Jujie Sun Changhao Feng Xiujuan Wang Minghan Xu Jingjiang Sun Ning Zhang Jun Ma Qingfu Wang Chengzhong Zong Guanglei Cui | 2021 | Journal of Energy Chemistry2021，30，4： | 2 |
| 9 | A polypyrrole-coated acetylene black/sulfur composite cathode material for lithium–sulfur batteries显示文摘Lithium–sulfur batteries are promising next-generation energy storage devices beyond conventional lithium ion batteries. However, it suffers from rapid capacity fading and poor cyclic stability. Here we report a facile in situ sulfur deposition and chemical oxidative polymerization method for preparing acetylene black/sulfur@polypyrrole(AB/S@PPy) composite as a cathode material for lithium–sulfur batteries. It is demonstrated that PPy is covered uniformly onto the surface of the AB/S composite forming a core–shell structure. In the structure, AB in the matrix and PPy on the surface acts as a combined conductive framework to provide ions and electrons transport pathways, and to inhibit the dissolution or diffusion of polysulfide into the electrolyte. The as-designed AB/S@PPy composite exhibits excellent rate capability and cyclic stability. The initial discharge specific capacity is as high as 1179.4 m Ah/g, and remains at769.3 m Ah/g after 80 cycles at 0.2 C. Even at a high rate(0.5 C), a maximum discharge capacity of 811.1 m Ah/g is still achieved for the AB/S@PPy composite after activation, and the capacity retention is over62.5% after 200 cycles. | Wu Yang Wang Yang Jiani Feng Xiujuan Qin | 2018 | Journal of Energy Chemistry2018，27，3： | 2 |
| 10 | Accelerated plasma degradation of organic pollutants in milliseconds and examinations by mass spectrometry显示文摘The rapid degradation of organic pollutants,process monitoring and online controlling to obtain advanced products and decreased by-products are great and challenging tasks in environmental treatments.Herein,an accelerated plasma degradation in milliseconds was achieved by combining electrospray-based acceleration and plasma-based degradation.Taking the degradation of chloroaniline as an example,97%of the degradation can be achieved in milliseconds.The velocity distribution of droplets was determined to be 40-50 m/s after being degraded for 0.30 ms,which exhibited different degradation behaviors in different milliseconds.Simultaneously,by virtue of the real-time and on-line detection ability of ambient mass spectrometry,intermediates,by-products and advanced products were monitored.Therefore,degradation mechanisms for different degradation times were proposed,which would provide theoretical guidance on obtaining efficient and green degradation.The fabrication,examining and understanding of accelerated plasma degradation not only enlarged application of accelerated reactions,but also promoted green and efficient degradation for environmental treatments. | Hua Lu Yiyan Yin Jianghui Sun Weixiang Li Xiaotong Shen Xiujuan Feng Jin Ouyang Na Na | 2021 | Chinese Chemical Letters2021，32，11： | 2 |
| 11 | High Rate and Long Lifespan Sodium‑Organic Batteries Using Pseudocapacitive Porphyrin Complexes‑Based Cathode显示文摘Sodium-organic batteries utilizing natural abundance of sodium element and renewable active materials gain great attentions for grid-scale applications.However,the development is still limited by lack of suitable organic cathode materials with high electronic conductivity that can be operated stably in liquid electrolyte.Herein,we present 5,15-bis(ethynyl)-10,20-diphenylporphyrin(DEPP)and[5,15-bis(ethynyl)-10,20-diphenylporphinato]copper(II)(CuDEPP)as new cathodes for extremely stable sodium-organic batteries.The copper(II)ion partially contributes the charge storage and significantly stabilizes the structure of porphyrin complex for electrochemical energy storage.In situ electrochemical stabilization of organic cathode with a lower charging current density was identified which enables both improved high energy density and power density.An excellent longterm cycling stability up to 600 cycles and an extremely high power density of 28 kW kg−1 were achieved for porphyrin-based cathode.This observation would open new pathway for developing highly stable sodium-organic cathode for electrochemical energy storage. | Xi Chen Xin Feng Bo Ren Liangzhu Jiang Hongbo Shu Xiukang Yang Zhi Chen Xiujuan Sun Enhui Liu Ping Gao | 2021 | Nano-Micro Letters2021，13，5： | 1 |

| 17 | 佛山地区一次局地暴雨过程的重力波特征分析显示文摘利用高精度微压计数据,详细分析了2016年11月20–21日佛山地区一次局地暴雨的重力波动态频谱特征,结果表明:重力波激发了此次暴雨,暴雨发生前,重力波呈现出振幅间歇性增大,周期范围不断增宽的过程;其中,暴雨前约4 h出现了重力波最大振幅80–160 Pa,相应的周期范围为140–270min。强雷暴对重力波的作用是积极的,会增大波的振幅,产生中心振幅约80–100 Pa,周期范围210–270 min重力波;尤其是,强雷暴激发了更短周期(≤36 min),振幅约10 Pa的重力波。大振幅重力波提前于暴雨出现,比雷达,卫星识别出强对流早了约4h,这一特征或许对局地强对流预警有指示意义。 | WANG Xiujuan LEI Hengchi FENG Liang ZHU Jiangshan LI Zhaoming JIANG Zhongbao | 2020 | Atmospheric and Oceanic Science Letters2020，13，2： | 1 |
