| 1 | A smart safe rechargeable zinc ion battery based on sol-gel transition electrolytes显示文摘Thermal runaway has been a long-standing safety issue impeding the development of high-energydensity batteries. Physical safety designs such as employing circuit-breakers and fuses to batteries are limited by small operating voltage windows and no resumption of original working condition when it is cooled down. Here we report a smart thermoresponsive polymer electrolyte that can be incorporated inside batteries to prevent thermal runaway via a fast and reversible sol-gel transition, and successfully combine this smart electrolyte with a rechargeable Zn/a-MnO_2 battery system. At high temperature, battery operation is inhibited as a result of the increased internal resistance caused by the gelation of liquid electrolyte. After cooling down, the electrolyte is spontaneously reversed to sol state and the electrochemical performance of the battery is restored. More importantly, sol-gel transition enables the smart battery to experience different charge-discharge rates under various temperature levels, providing a smart and active strategy to achieve dynamic and reversible self-protection. | Funian Mo Hongfei Li Zengxia Pei Guojin Liang Longtao Ma Qi Yang Donghong Wang Yan Huang Chunyi Zhi | 2018 | Science Bulletin2018，63，16： | 13 |
| 2 | Spatial-temporal variation of phytoplankton community structure in Jiaozhou Bay, China显示文摘To better understand the spatial-temporal variation in phytoplankton community structure and its controlling factors in Jiaozhou Bay, Qingdao, North China, four seasonal sampling were carried out in 2017. The phytoplankton community structure and various environmental parameters were examined. The phytoplankton community in the bay was composed of mainly diatoms and dinofl agellates, and several other species of Chrysophyta were also observed. Diatoms were the most dominant phytoplankton group throughout the year, except in spring and winter, when Noctiluca scintillans was co-dominant. High Si/N ratios in summer and fall refl ect the high dominance of diatoms in the two seasons. Temporally, the phytoplankton cell abundance peaked in summer, due mainly to the high temperatures and nutrient concentrations in summer. Spatially, the phytoplankton cell abundance was higher in the northern part of the bay than in the other parts of the bay in four seasons. The diatom cell abundances show signifi cant positive correlations with the nutrient concentrations, while the dinofl agellate cell abundances show no correlation or a negative correlation with the nutrient concentrations but a signifi cant positive correlation with the stratifi cation index. This discrepancy was mainly due to the diff erent survival strategies between diatoms and dinofl agellates. The Shannon-Wiener diversity index ( H′) values in the bay ranged from 0.08 to 4.18, which fell in the range reported in historical studies. The distribution pattern of H′ values was quite diff erent from that of chlorophyll a , indicating that the phytoplankton community structure might have high biomass with a low diversity index. Compared with historical studies, we believe that the dominant phytoplankton species have been changed in recent years due mainly to the changing environment in the Jiaozhou Bay in recent 30 years. | GUO Shujin ZHU Mingliang ZHAO Zengxia LIANG Junhua ZHAO Yongfang DU Juan SUN Xiaoxia | 2019 | Journal of Oceanology and Limnology2019，37，5： | 6 |
| 3 | Tempo-spatial Variation of Nutrient and Chlorophyll-a Concentrations From Summer to Winter in the Zhangzi Island Area (Northern Yellow Sea)显示文摘Nutrient and Chlorophyll-a(Chl-a) concentrations were investigated monthly along three transects extending from a mariculture area to open waters around the Zhangzi Island area from July to December 2009.The objective of this study is to illustrate food availability to the bottom-sowed scallop Patinopecten yessoensis under the influences of the Yellow Sea Cold Water Mass(YSCWM),freshwater input and feedbacks of cultivated scallops.Significant thermal stratification was present in open waters from July to October,and salinity decreased in July and August in surface layers in the mariculture area.Nutrient concentrations increased with depth in both areas in summer,but were similar through water column in November and December.On average,nutrient increased from summer to autumn in all components except ammonia.Nutrient concentrations lower than the minimum thresholds for phytoplankton growth were present only in upper layers in summer,but stoichiometric nitrogen limitation existed in the entire investigation period.Column-averaged Chl-a concentration was lower in open waters than in mariculture area in all months.It increased significantly in mariculture area in August and October,and was less variable in open waters.Our results show that nutrients limitation to phytoplankton growth is present mainly in upper layer in association with stratification caused by YSCWM in summer.Freshwater input and upwelling of nutrients accumulated in YSCWM can stimulate phytoplankton production in mariculture area.Farming activities may change stoichiometric nutrient ratios but have less influence on Chl-a concentration. | YIN Jiehui ZHAO Zengxia ZHANG Guangtao WANG Shiwei WAN Aiyong | 2013 | Journal of Ocean University of China2013，12，3： | 4 |

| 5 | Ethacrynic acid targets GSTM1 to ameliorate obesity by promoting browning of white adipocytes显示文摘Dear Editor,Obesity is caused by an imbalance between energy intake and expenditure,and has become a global epidemic with over 650 million adults affected.Adipose tissues in mammals are composed of white adipose tissue(WAT)and classical brown adipose tissue(BAT),and their balance is highly related to the occurrence of obesity.The browning of white adipocytes results in“beige”or“brite”adipocytes,which appear functionally similar to classical brown adipocytes,and can be detected in WAT deposits of animals that have been exposed to cold or other inducers(Fu et al.,2015). | Zhaomeng Cui Yang Liu Wei Wan Yuyan Xu Yehui Hu Meng Ding Xin Dou Ruina Wang Hailing Li Yongmei Meng Wei Li Wei Jiang Zengxia Li Yiming Li Minjia Tan Dengke KMa Yu Ding Jun OLiu Cheng Luo Biao Yu Qiqun Tang Yongjun Dang | 2021 | Protein & Cell2021，12，6： | 1 |
| 6 | Continuous culture of urine-derived bladder cancer cells for precision medicine显示文摘Dear Editor,Bladder cancer is the most common type of genitourinary cancer in China,with an estimated 80,500 new cases and 32,900 related deaths in 2015 alone(Chen et al.,2016).Unlike many other cancers,there has been no significant improvement in survival rates for bladder cancer over the last three decades.Specific treatment regimens for bladder cancer and their efficacy vary depending not only on clinical stages,but also on associated risk factors and other personal clinical characteristics.Patients with non-muscle invasive bladder cancer(NMIBC)have a high 5-year recurrence rate of 60%-70%(Berdik,2017)and those with muscle invasive bladder cancer(MIBC)has a relatively poor prognosis with approximately 65%risk of death within 5-year follow-up(Kamat et al.,2016).Therefore,there is an urgent need to develop models for bladder cancer to screen for rational treatment strategies by personalized medicine to improve the clinical assessment and treatment of bladder cancer. | Shuai Jiang Jiaqi Wang Chen Yang Renke Tan Jun Hou Yuan Shi Huihui Zhang Shiyu Ma Jianan Wang Mengmeng Zhang George Philips Zengxia Li Jian Ma Wanjun Yu Guohua Wang Yuanming Wu Richard Schlegel Huina Wang Shanbo Cao Jianming Guo Xuefeng Liu Yongjun Dang | 2019 | Protein & Cell2019，10，12： | 1 |

| 9 | High sulfur loading and shuttle inhibition of advanced sulfur cathode enabled by graphene network skin and N,P,F-doped mesoporous carbon interfaces for ultra-stable lithium sulfur battery显示文摘Achieving high loading of active sulfur yet rational regulating the shuttle effect of lithium polysulfide(LiPS)is of great significance in pursuit of high-performance lithium-sulfur(Li-S)battery.Herein,we develop a free-standing graphene nitrogen(N),phosphorus(P)and fluorine(F)co-doped mesoporous carbon-sulfur(G-NPFMC-S)film,which was used as a binder-free cathode in Li-S battery.The developed mesoporous carbon(MC)achieved a high specific surface area of 921 m^(2)·g^(-1)with a uniform pore size distribution of 15 nm.The inserted graphene network inside G-NPFMC-S cathode can effectively improve its electrical conductivity and simultaneously restrict the shuttle of LiPS.A high sulfur loading of 86%was achieved due to the excellent porous structures of graphene-NPFMC(G-NPFMC)composite.When implemented as a freestanding cathode in Li-S battery,this G-NPFMC-S achieved a high specific capacity(1,356 mAh·g^(-1)),favorable rate capability,and long-term cycling stability up to 500 cycles with a minimum capacity fading rate of 0.025%per cycle,outperforming the corresponding performances of NPFMC-sulfur(NPFMC-S)and MC-sulfur(MC-S).These promising results can be ascribed to the featured structures that formed inside G-NPFMC-S film,as that highly porous NPFMC can provide sufficient storage space for the loading of sulfur,while,the N,P,F-doped carbonic interface and the inserted graphene network help hinder the shuttle of LiPS via chemical adsorption and physical barrier effect.This proposed unique structure can provide a bright prospect in that high mass loading of active sulfur and restriction the shuttle of LiPS can be simultaneously achieved for Li-S battery. | Haotian Liu Fan Liu Zehua Qu Jieling Chen Hui Liu Yiqing Tan Jiabao Guo Yan Yan Shuang Zhao Xinsheng Zhao Xinming Nie Xin Ma Zengxia Pei Mingkai Liu | 2023 | Nano Research Energy2023，2，1： | 1 |
| 10 | Graphene stirrer with designed movements:Targeting on environmental remediation and supercapacitor applications显示文摘Beyond the traditional focus on improvements in mechanical, electronic and absorption properties, controllability, actuation, and dynamic response of monoliths have received increasing attentions for practical applications. However, most of them could only realize simple response to constant conditions(e.g. a stationary magnetic field) while carrying out humdrum motions. By controlling distribution of metal organic framework obtained carbon-enriched Fe304 nanoparticles in self-assembly reduced graphene oxide(RGO) monoliths, we could achieve two distinctive RGO-Fe_3 O_4 stirrers that could dynamically respond to the rapidly changing magnetic field while executing designed movements precisely: rotating with lying down posture or standing straight posture. These stirrers can not only be applied in environmental remediation(e.g.suction skimmer), but also be recycled as electrode active materials for supercapacitors after fulfilling their destiny, realizing transformation of trash to treasure, which will inspire other dynamically responsive monoliths for various applications. | Yang Huang Wei Chen Hongfei Li Minshen Zhu Fuwei Liu Qi Xue Zengxia Pei Zifeng Wang Lei Wang Yan Huang Chunyi Zhi | 2018 | Green Energy & Environment2018，3，1： | 1 |
| 11 | Influence of a Flood Event on Salinity and Nutrients in the Changshan Archipelago Area (Northern Yellow Sea)显示文摘River discharge can deliver nutrients to the coastal zone and change the hydrologic properties of the water column. Soon after a flash flood from the Yalu River (Northeast China) in August 2010, we investigated the salinity and nutrient concentrations, as well as other environmental conditions in the Changshan Archipelago area, located approximately 100 km west of the river mouth in the northern Yellow Sea. Diluted water was mainly observed in the upper layers shallower than 15 m, with surface salinity between 18.13 and 30.44 in the eastern study area and between 28.16 and 29.72 in the western area. Surface salinity showed a significant negative correlation with concentrations of dissolved nutrients (P < 0.05), but not with that of Chlorophyll-a (Chl-a), dissolved oxygen (DO), particulate materials or pH. The average concentrations of nitrite, nitrate, and silicic acid decreased from the surface layer to bottom layer and were significantly higher in the east area than in the west area (P < 0.05). In contrast, average ammonium and phosphate concentrations were highest in the bottom layer of both areas, with no significant spatial differences. DO varied between 6.06 and 8.25 mg L-1 in the surface layer, and was significantly higher in the eastern area than in the western area in the surface and middle layers. Chl-a concentration was constantly below 4.09 μg L-1. Our work demonstrated the strong influences of Yalu River on proportions of various nutrient components in the Changshan Archipelago area. Silicic acid and total inorganic nitrogen levels were significantly elevated comparing to phosphate in the eastern area. Such changes can potentially induce phosphate limit to phytoplankton growth. | ZHANG Guangtao ZHAO Zengxia LIU Changhua LIU Qun REN Jianming | 2012 | Journal of Ocean University of China2012，11，3： | 0 |
| 12 | STUDY ON ELEVATED TEMPERA-TURE MECHANICAL PROPERTIES OF AM50HP WITH ND显示文摘Effects of Nd on the mechanical properties of die casting magnesium alloys AM50 are investigated. It is found that the ultimate tensile strength, yield strength and elongation of the AM50 alloy at elevated temperatures up to 200 (C increase with an addition of Nd. Generally, the most significant improvement in the tensile properties is attained at 100 (C. The presence of Mg12Nd is proved by X-ray diffraction. Microstructural observations reveal that the addition of Nd can lead to the dispersion-strengthening. Due to the presence of Mg12Nd, the sliding of grain boundaries is restrained and the strength of the alloy is enhanced. It can be seen from the tensile fractographs that the fracture surfaces exhibit the mixed fracture characteristics, and less brittle fracture is observed with increasing the temperature. Quasi-cleavage fracture is thought as the main fracture mode. TEM observations expose the formation of dislocation network, slip lines and dislocation pile-ups. | LiFeng ZengXia WangYue LiuZheng ZhouJiyang | 2003 | Chinese Journal of Mechanical Engineering2003，16，3： | 0 |
| 13 | A novel in vitro prognostic model of bladder cancer based on urine-derived living tumor cells显示文摘Bladder cancer(BLCA)remains a difficult malignancy to manage because of its high recurrence,intense follow-up,and invasive diagnostic and treatment techniques.Immune checkpoint inhibitors(ICIs)have forged a new direction for the treatment of BLCA,but it is currently challenging to predict whether an individual patient will be sensitive to ICIs.We collected 43 urine/tumor samples from BLCA patients for primary bladder cancer cells(BCCs)culturing using our previously reported BCC culture platform.We used flow cytometry(FCM)to measure the expression levels of Programmed Death-Ligand 1(PD-L1)on BCCs before and after interferon-gamma(IFN-γ)treatment and found that PD-L1 expression and the sensitivities to IFN-γvaried among patients.RNA-sequencing,western blotting,and programmed death-1(PD-1)binding assays confirmed that the BCC FCM-based PD-L1 detection platform(BC-PD-L1)was reliable and was not hindered by the glycosylation of PD-L1.In the subsequent retrospective study,we found that IFN-γ-stimulated PD-L1(sPD-L1)expression on BCCs detected by BC-PD-L1 could predict the prognosis of BLCA patients.Importantly,the prognostic value was similar or even better in urine-derived BC-PD-L1(UBC-PD-L1).Transcriptome analysis showed that BCCs with high sPD-L1 tended to enrich genes associated with the collagen-containing extracellular matrix,cell–cell adhesion,and positive regulation of the immune system.In addition,the UBC-PD-L1 also exhibited predictive value for ICI response in BLCA patients.In conclusion,as a novel personalized urine-detection method,UBC-PD-L1 may provide a rapid,accurate,and non-invasive tool for monitoring tumor progression,predicting therapeutic responses,and helping improve BLCA clinical treatment in future. | Jiaqi Wang Jiying Zhu Junchi Hu Ziruoyu Wang Xiaobo Wang Jianbo Pan Yiwei Chu Zengxia Li Wei Jiang Chunmin Liang Jun Hou Jianming Guo Yongjun Dang Shuai Jiang | 2023 | Genes & Diseases2023，10，6： | 0 |
| 14 | Surface plasmon enhanced solar-blind photoresponse of Ga2O3 film with Ga nanospheres显示文摘Semiconductor solar-blind(220-280 nm)photodetectors(PDs),which have important applications both in civil and military aspects,are mainly based on diamond[1],Al Ga N[2],Mg Zn O[3],and Ga_2O_3[4-11].Among these materials,Ga_2O_3has a direct band gap(~4.9 e V)just falling in solarblind spectral range,which makes Ga_2O_3a desirable candidate for solar-blind photodetection.Up to now,many kinds of Ga_2O_3PDs have been demonstrated including bulk[4,5],film[6-8]and nanostructures[9-11],as summarized in Table 1.From the summary,we can see although bulk | Shujuan Cui Zengxia Mei Yaonan Hou Muhua Sun Quansheng Chen Huili Liang Yonghui Zhang Xuedong Bai Xiaolong Du | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，10： | 0 |
| 15 | Nucleolus localization of SpyCas9 affects its stability and interferes with host protein translation in mammalian cells显示文摘The CRISPR/Cas9 system,originally derived from the prokaryotic adaptive immune system,has been developed as efficient genome editing tools.It enables precise gene manipulation on chromosomal DNA through the specific binding of programmable sgRNA to target DNA,and the Cas9 protein,which has endonuclease activity,will cut a double strand break at specific locus.However,Cas9 is a foreign protein in mammalian cells,and the potential risks associated with its introduction into mammalian cells are not fully understood.In this study,we performed pull-down and mass spectrometry(MS)analysis of Streptococcus pyogenes Cas9(SpyCas9)interacting proteins in HEK293T cells and showed that the majority of Cas9-associated proteins identified by MS were localized in the nucleolus.Interestingly,we further discovered that the Cas9 protein contains a sequence encoding a nucleolus detention signal(NoDS).Compared with wild-type(WT)Cas9,NoDS-mutated variants of Cas9(mCas9)are less stable,although their gene editing activity is minimally affected.Overexpression of WT Cas9,but not mCas9,causes general effects on transcription and protein translation in the host cell.Overall,identification of NoDS in Cas9 will improve the understanding of Cas9's biological function in vivo,and the removal of NoDS in Cas9 may enhance its safety for future clinical use. | Renke Tan Wenhao Du Yiyang Liu Xiaoji Cong Meirong Bai Chenxiao Jiang Zengxia Li Minjia Tan Dengke K.Ma Qiang Huang Wei Jiang Yongjun Dang | 2022 | Genes & Diseases2022，9，3： | 0 |
| 16 | Symmetric is nonidentical:Operation history matters for Zn metal anode显示文摘Zn metal electrode is the key to enabling the full vision of next-generation Zn-metal batteries(ZMBs).Thus far,the critical dendrite issue still restricts the Zn anode lifespan,which has even become the Achilles heel to the rejuvenation of ZMBs.This highlight previews the latest advance of Zn anode research,which suggests that Zn electrodes with initial stripping and plating can surprisingly lead to different morphology evolution routes.A proposed pre-deposition strategy is demonstrated to stabilize the Zn anode and homogenize further Zn plating/stripping. | Zengxia Pei | 2022 | Nano Research Energy2022，1，2： | 0 |
| 17 | Integrative multi-omics and drug-response characterization of patient-derived prostate cancer primary cells显示文摘Prostate cancer(PCa)is the second most prevalent malignancy in males across the world.A greater knowledge of the relationship between protein abundance and drug responses would benefit precision treatment for PCa.Herein,we establish 35 Chinese PCa primary cell models to capture specific characteristics among PCa patients,including gene mutations,mRNA/protein/surface protein distributions,and pharmaceutical responses.The multi-omics analyses identify Anterior Gradient 2(AGR2)as a pre-operative prognostic biomarker in PCa.Through the drug library screening,we describe crizotinib as a selective compound for malignant PCa primary cells.We further perform the pharmacoproteome analysis and identify 14,372 significant protein-drug correlations.Surprisingly,the diminished AGR2 enhances the inhibition activity of crizotinib via ALK/c-MET-AKT axis activation which is validated by PC3 and xenograft model.Our integrated multi-omics approach yields a comprehensive understanding of PCa biomarkers and pharmacological responses,allowing for more precise diagnosis and therapies. | Ziruoyu Wang Yanan Li Wensi Zhao Shuai Jiang Yuqi Huang Jun Hou Xuelu Zhang Zhaoyu Zhai Chen Yang Jiaqi Wang Jiying Zhu Jianbo Pan Wei Jiang Zengxia Li Mingliang Ye Minjia Tan Haowen Jiang Yongjun Dang | 2023 | Signal Transduction and Targeted Therapy2023，8，6： | 0 |
| 18 | Carbon biomass,carbon-to-chlorophyll a ratio and the growth rate of phytoplankton in Jiaozhou Bay,China显示文摘Carbon biomass,carbon-to-chlorophyll a ratio(C꞉Chl a),and the growth rate of phytoplankton cells were studied during four seasonal cruises in 2017 and 2018 in Jiaozhou Bay,China.Water samples were collected from 12 stations,and phytoplankton carbon biomass(phyto-C)was estimated from microscope-measured cell volumes.The phyto-C ranged from 5.05 to 78.52μg C/L in the bay,and it constituted a mean of 38.16% of the total particulate organic carbon in the bay.High phyto-C values appeared mostly in the northern or northeastern bay.Diatom carbon was predominant during all four cruises.Dinoflagellate carbon contributed much less(<30%)to the total phyto-C,and high values appeared often in the outer bay.The C꞉Chl a of phytoplankton cells varied from 11.50 to 61.45(mean 31.66),and high values appeared in the outer bay during all four seasons.The phyto-C was also used to calculate the intrinsic growth rates of phytoplankton cells in the bay,and phytoplankton growth rates ranged from 0.56 to 1.96/d;the rate was highest in summer(mean 1.79/d),followed by that in fall(mean 1.24/d)and spring(mean 1.17/d),and the rate was lowest in winter(mean 0.77/d).Temperature and silicate concentration were found to be the determining factors of phytoplankton growth rates in the bay.To our knowledge,this study is the first report on phytoplankton carbon biomass and C꞉Chl a based on water samples in Jiaozhou Bay,and it will provide useful information for studies on carbon-based food web calculations and carbon-based ecosystem models in the bay. | Shujin GUO Zengxia ZHAO Junhua LIANG Juan DU Xiaoxia SUN | 2021 | Journal of Oceanology and Limnology2021，39，4： | 0 |
| 19 | GaZn-VZn acceptor complex defect in Ga-doped ZnO显示文摘Gallium(Ga)-doped Zn O is regarded as a promising plasmonic material with a wide range of applications in plasmonics. In this study, zinc self-diffusion experiments are adopted to disclose the nature of the dominant compensating defect in Ga-doped Zn O isotopic heterostructures. The(Ga_(Zn)-V_(Zn))^- complex defect, instead of the isolated V_(Zn)^(2-), is identified as the predominant compensating acceptor center responsible for the low donor doping efficiency. The comparative diffusion experiments operated by the secondary ion mass spectrometry reveal a ~0.78 e V binding energy of this complex defect, which well matches the electrical activation energy derived from the temperature-dependent Hall effect measurements(^(0.82±0.02) e V). These findings contribute to an essential understanding of the(Ga_(Zn)-V_(Zn))^- complex defect and the potential engineering routes of heavily Ga-doped ZnO. | AiHua Tang ZengXia Mei YaoNan Hou LiShu Liu Vishnukanthan Venkatachalapathy Alexander Azarov Andrej Kuznetsov XiaoLong Du | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，7： | 0 |
| 20 | Strain-enhanced polarization sensitivity inβ-Ga_(2)O_(3)photodetector显示文摘Polarization-sensitive photodetection and imaging have great application value in fields such as polarization division multiplexing optical communication,remote sensing,near-field imaging and military monitoring.Pursuing a high polarization ratio has always been the research hotspot in polarization-sensitive photodetectors.In this paper,we report a compression strain enhanced polarization ratio inβ-gallium oxide(β-Ga_(2)O_(3))single crystal flake.A rigorous crystallographic analysis confirmed its high crystalline quality and orientation.Angle-resolved polarization Raman spectroscopy(ARPRS)was adopted to study the anisotropy of its optical properties.Extensive ARPRS measurements and theoretical calculation consistently demonstrate the strong optical anisotropy in the high-qualityβ-Ga_(2)O_(3)flake.A polarization ratio of 0.96 was obtained in the flatβ-Ga_(2)O_(3)flake.Furthermore,mechanical strain of±0.7%was introduced intoβ-Ga_(2)O_(3).An increased polarization ratio of 0.98 was achieved in the case of 0.7%compression strain,which is,to the best of our knowledge,the highest value for UVC polarization-sensitive photodetectors.That corresponds to an improved polarization rejection ratio of 100.This work proposed a new path towards improving polarization sensitivity by applying strain engineering in the active material. | Yonghui Zhang Huili Liang Fei Xing Qiqian Gao Yu Feng Yuping Sun Zengxia Mei | 2024 | Science China(Physics,Mechanics & Astronomy)2024，67，4： | 0 |
