| 1 | Growth and Repair Potential of Three Species of Bacteria in Reclaimed Wastewater after UV Disinfection显示文摘Objective The growth and repair potential of three typical microorganisms in reclaimed water after UV disinfection was investigated to assess the effects of photo-reactivation and dark repair of microorganisms,and the microbial safety of reclaimed water following this procedure.Methods The growth and repair potential of Escherichia coli,a fecal coliform strain and Bacillus subtilis in the effluent of a biological wastewater treatment plant disinfected by a low-pressure UV lamp were investigated.Results Any increase in bacterial numbers in the effluent after UV disinfection was due to damage repair.Exposure to photo-reactivating light for 8-10 h after UV irradiation with a dose of 5 mJ/cm 2,the highest percentage of photo-reactivation observed for E.coli and the fecal coliform strain was 29% and 15% respectively.B.subtilis showed little photo-reactivation under these conditions.The percentage of photo-reactivation was related to the UV dose and the photo-reactivating time,and a function was developed to forecast the final concentrations of E.coli and the fecal coliform strain after UV disinfection with possible photo-reactivation.Conclusion Different species of bacteria displayed different responses to UV light and different repair potentials.The repair of indigenous bacteria in wastewater needs to be investigated in future work. | GUO MeiTing HUANG JingJing HU HongYing LIU WenJun | 2011 | Biomedical and Environmental Sciences2011，24，4： | 8 |
| 2 | Synthesis of MoX2 (X =Se or S) monolayers with high-concentration 1T'phase on 4H/fcc-Au nanorods for hydrogen evolution显示文摘Controlled synthesis of transition metal dichalcogenide (TMD) monolayers with unusual crystal phases has attracted increasing attention due to their promising applications in electrocatalysis.However,the facile and large-scale preparation of TMD monolayers with high-concentration unusual crystal phase still remains a challenge.Herein,we report the synthesis of MoX2 (X =Se or S) monolayers with high-concentration semimetallic 1T'phase by using the 4H/face-centered cubic (fcc)-Au nanorod as template to form the 4H/fcc-Au@MoX2 nanocomposite.The concentrations of 1T'phase in the prepared MoSe2 and MoS2 monolayers are up to 86% and 81%,respectively.As a proof-of-concept application,the obtained Au@MoS2 nanocomposite is used for the electrocatalytic hydrogen evolution reaction (HER) in acid medium,exhibiting excellent performance with a low overpotential of 178 mV at the current density of 10 mNcm^2,a small Tafel slope of 43.3 mV/dec,and excellent HER stability.This work paves a way for direct synthesis of TMD monolayers with high-concentration of unusual crystal phase for the electrocatalytic application. | Zhengqing Liu Xiao Zhang Yue Gong Qipeng Lu Zhicheng Zhang Hongfei Cheng Qinglang Ma Junze Chen Meiting Zhao Bo Chen Ye Chen Xue-Jun Wu Pengfei Yin Lin Gu Yaping Du Hua Zhang | 2019 | Nano Research2019，12，6： | 3 |

| 7 | High-Entropy Perovskite Oxide: A New Opportunity for Developing Highly Active and Durable Air Electrode for Reversible Protonic Ceramic Electrochemical Cells显示文摘Reversible proton ceramic electrochemical cell(R-PCEC)is regarded as the most promising energy conversion device,which can realize efficient mutual conversion of electrical and chemical energy and to solve the problem of large-scale energy storage.However,the development of robust electrodes with high catalytic activity is the main bottleneck for the commercialization of R-PCECs.Here,a novel type of high-entropy perovskite oxide consisting of six equimolar metals in the A-site,Pr_(1/6)La_(1/6)Nd_(1/6)Ba_(1/6)Sr_(1/6)Ca_(1/6)CoO_(3−δ)(PLN-BSCC),is reported as a high-performance bifunctional air electrode for R-PCEC.By harnessing the unique functionalities of multiple ele-ments,high-entropy perovskite oxide can be anticipated to accelerate reaction rates in both fuel cell and electrolysis modes.Especially,an R-PCEC utilizing the PLNBSCC air electrode achieves exceptional electrochemical performances,demonstrating a peak power density of 1.21 W cm^(−2)for the fuel cell,while simultaneously obtaining an astonishing current density of−1.95 A cm^(−2)at an electrolysis voltage of 1.3 V and a temperature of 600℃.The significantly enhanced electrochemical performance and durability of the PLNBSCC air electrode is attributed mainly to the high electrons/ions conductivity,fast hydration reactivity and high configurational entropy.This research explores to a new avenue to develop optimally active and stable air electrodes for R-PCECs. | Zuoqing Liu Zhengjie Tang Yufei Song Guangming Yang Wanru Qian Meiting Yang Yinlong Zhu Ran Ran Wei Wang Wei Zhou Zongping Shao | 2022 | Nano-Micro Letters2022，14，12： | 1 |
| 8 | Bismuth doped Sr_(2)Fe_(1.5)Mo_(0.5)O_(6)-δdouble perovskite as a robust fuel electrode in ceramic oxide cells for direct CO_(2)electrolysis显示文摘Electrochemical conversion of CO_(2)to CO is an economically feasible method for mitigating greenhouse gas emissions.Among various electrochemical approaches,solid oxide electrolysis cells(SOECs)show high potential for CO_(2)reduction reaction(CO_(2)-RR)due to their ability to operate at high temperatures,resulting in fast reaction kinetics and increased efficiency.Considering their main energy loss is still associated with the large overpotential at the fuel electrode,the development of the highly efficient and durable cathode for SOECs has been extensively searched after.Here,we propose an A-site doping strategy to enhance the properties of Sr_(2)Fe_(1.5)Mo_(0.5)O_(6)−δ(SFM),which improve its performance as a cathode in SOECs for CO_(2)-RR,demonstrating favorable activity and durability.The structural and physiochemical characterizations,together with DFT calculations,show that the partial replacement of Sr by Bi in the SFM double perovskite not only improves CO 2 adsorption capability at the catalyst surface but also enhances oxygen ionic conduction inside the bulk oxide,resulting in enhanced CO_(2)electrocatalysis performance in SOECs.Specifically,a La_(0.8)Sr_(0.2)Ga_(0.8)Mg_(0.2)O_(3)−δ(LSGM)electrolyte-supported single cell with the new Bi-doped SFM cathode demonstrates a large current density of 1620 mA cm^(−2) at a cell potential of 1.6 V at 850°C with good operational stability up to 200 h.Bi-doped SFM thus represents a highly promising cathode for ceramic CO_(2)electrolyzers and could accelerate our transition towards a carbon-neutral society. | Meiting Yang Zhen Yao Shuai Liu Jun Wang Anwei Sun Haoran Xu Guangming Yang Ran Ran Wei Zhou Gang Xiao Zongping Shao | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
| 9 | Differential pricing and production strategies for heterogeneous products under cannibalization and promotional effects显示文摘This study examines the optimal pricing and production strategy of a closed-loop supply chain consisting of a manufacturer, a recycler, and consumers. Considering the cannibalization and promotion effects of remanufactured products on new and secondhand products, we constructed Stackelberg game models under different scenarios. We analyze the impact of the changes in the two effects on the optimal prices and production strategies of the manufacturer and recycler, as well as their countermeasures. We find that (i) how the cannibalization and promotional effects influence the manufacturer and the recycler's pricing and production strategies differ under different scenarios;(ii) when the two effects exceed a threshold, the manufacturer abandons new or remanufactured products, and the recycler prefers to stop production on its new products or continue to remanufacture products;and (iii) the two effects always reduce the profits of the manufacturer and increase the profits of the recycler. | Aijun Liu Meiting Jing Jie Miao Zengxian Li Yun Yang | 2022 | Journal of Management Science and Engineering2022，7，4： | 0 |

| 12 | Development and application of high-precision multifunction astronomical plate digitizers in China显示文摘Before charge-coupled device detectors became widely employed in observational astronomy,for more than a hundred years,the main detection method was photography on astronomical glass plates.Recently,in order to preserve these historical data and maintain their usability,the International Astronomical Union has appealed to all countries for global digitization of astronomical plates by developing or adopting advanced digitization technology.Specialized digitizers with high precision and high measuring speed represent key equipment for this task.The Shanghai Astronomical Observatory and the Nishimura Co.,Ltd in Japan cooperated between 2013 and 2016 to develop the first Chinese high-precision astronomical plate digitizer,which was then used for complete digitization of all nighttime-observation astronomical plates in China.Then,in 2019–2021,the Shanghai Astronomical Observatory independently developed new models of plate digitizers that enabled countries such as Uzbekistan and Italy to digitize their astronomical plates.Additionally,a new high-precision and multifunction digitizer was also used to digitize valuable microscope slides from the Shanghai Natural History Museum,providing a successful example of cross-domain application of high-precision digitization technology. | Meiting Yang Yong Yu Liangliang Wang Zhengjun Shang Changshun Liu Lixin Zheng Zhendong Chen Jing Yang Dongmei Da Shan Dong Shiyin Shen Zhenghong Tang Jianhai Zhao | 2024 | Astronomical Techniques and Instruments2024，1，1： | 0 |
| 13 | Recent advances and research progress on microsystems and bioeffects of terahertz neuromodulation显示文摘Terahertz waves can interact with the nervous system of organisms under certain conditions.Compared to common optical modulation methods,terahertz waves have the advantages of low photon energy and low risk;therefore,the use of terahertz waves to regulate the nervous system is a promising new method of neuromodulation.However,most of the research has focused on the use of terahertz technology for biodetection,while relatively little research has been carried out on the biological effects of terahertz radiation on the nervous system,and there are almost no review papers on this topic.In the present article,we begin by reviewing principles and objects of research regarding the biological effects of terahertz radiation and summarizing the current state of related research from a variety of aspects,including the bioeffects of terahertz radiation on neurons in vivo and in vitro,novel regulation and detection methods with terahertz radiation devices and neural microelectrode arrays,and theoretical simulations of neural information encoding and decoding.In addition,we discuss the main problems and their possible causes and give some recommendations on possible future breakthroughs.This paper will provide insight and assistance to researchers in the fields of neuroscience,terahertz technology and biomedicine. | Meiting Liu Juntao Liu Wei Liang Botao Lu Penghui Fan Yilin Song Mixia Wang Yirong Wu Xinxia Cai | 2023 | Microsystems & Nanoengineering2023，9，6： | 0 |
| 14 | A novel two-dimensional nanoheterojunction via facilitating electron–hole pairs separation for synergistic tumor phototherapy and immunotherapy显示文摘Nanomaterial-mediated phototherapy in tumor treatment has been developed rapidly in the past few years due to its noninvasive character.However,the low energy conversion efficiency and high recombination rate of the photo-triggered electron–hole pairs of single nano-agent limit the phototherapy efficiency.Herein,we constructed a novel two-dimensional nanoheterojunction MoS_(2)-Ti_(3)C_(2)(MT),which allowed a high photothermal conversion efficiency(59.1%)as well as an effective separation of photo-triggered electron–hole pairs for reactive oxygen species(ROS)generation under single 808 nm laser irradiation.Upon the modification of the mitochondrial targeted molecule(3-proxycarboxylic)triphenyl phosphine bromide(TPP)and 4T1 cell membrane,m@MoS_(2)-Ti_(3)C_(2)/TPP(m@MTT)could effectively target to the tumor cell and further locate to the mitochondria to amplify tumor-specific oxidative stress,which not merely effectively inhibits the local tumor growth but also induces tumor immunogenic cell death(ICD)for activating antitumor immune response.Additionally,cytosine guanine dinucleotide(CPG),as a Toll-like receptor 9(TLR9)agonist,was further introduced to the system to boost adaptive immune responses,resulting in improved level of cytotoxic T cells as well as a decrease in the number of regulatory T cells.In vivo antitumor mechanism studies demonstrated that not only the primary and distant tumors in 4T1 bearing-tumor mice model were significantly inhibited,but also the lung metastasis of tumor was effectively suppressed.Therefore,this work revealed the ROS generation mechanism of MT nanoheterojunction and provided a novel strategy to fabricate a biomedically applicable MT nanoheterojunction for tumor treatment. | Xiaoge Zhang Xiaomei Chen Peng Zhang Meiting Li Miao Feng Yaqian Zhang Lili Cheng Junjie Tang Langtao Xu Yadong Liu Zhuoyin Liu Zhong Cao Jie Liu | 2023 | Nano Research2023，16，5： | 0 |
| 15 | A specific assay for JmjC domain-containing lysine demethylase and its application to inhibitor screening显示文摘Dear Editor, Chromatin is the macromolecular complex of DNA and histone proteins, which provides the scaffold for the packaging of our entire genome. In the basic unit of chromatin, the nucleosomes contain 147 base pairs of DNA, which is wrapped around a histone octamer, with two each of histones H2A, H2B, H3, and H4. Several types of post-translational modifications, including acetylation, phosphorylation, ubiquitination, and methylation, are possible on the tails of histones (Zhang et al., 2015). Combinations of these modifications determine the chromatin structure and transcriptional regulation of genes. Histone methylation is highlighted because of the specific dynamics related to gene regulation. Aberrant histone methylation has been observed in many types of tumors (Albert and Helin, 2010) and may contribute to the neoplastic transformation of cells (Chi et al., 2010). Histone lysine methylation is regulated by two classes of enzymes that have opposing activities: histone lysine methyltransferases (KMTs) and histone lysine demethylases (KDMs). To date, a number of mammalian KDMs have been discovered (Kooistra and Helin, 2012), and they have been separated into two classes: flavin adenine dinucleotide dependent oxidases, which were first discovered in 2004 (Shi et al., 2004), and Jumonji-C (JmjC) domain-containing enzymes, first identified in 2006 (Tsukada et al., 2006). | He Wen Guo Li Yongcan Chen Meiting Li Yafei Lv Zhiming Li Yinglu Li Tianyun Hou Hui Wang Chaohua Liu Xiaopeng Lu Qian Zhu Yantao Bao Ge Liu Xiaofan Li Wei-Guo Zhu | 2019 | Science China(Life Sciences)2019，62，10： | 0 |
