| 1 | Research progress in artificial upwelling and its potential environmental effects显示文摘Artificial upwelling, as a geoengineering tool, has received worldwide attention because it may actualize ocean fertilization in a sustainable way, which could potentially alleviate the pressures on the fish stocks and human-driven climate change in the ocean. We reviewed the current knowledge on the development of an artificial upwelling system and its potential environmental effects. Special attention was given to the research progress on the air-lift concept artificial upwelling by Zhejiang University. The research on artificial upwelling over the past few decades has generated a range of devices that have been successfully applied in the field for months. Based on field experiments and the associated modeling results, part of them reported positive effects on increasing primary production and enhancing CO2 sequestration. However, as a significant disturbance to the environment, especially for large-scale applications, the uncertainties related to the potential effects on ecosystem remain unsolved. Zhejiang University has overcome the technical challenges in designing and fabricating a robust and high efficiency artificial upwelling device which has been examined in two field experiments in Qiandao Lake and one sea trial in the East China Sea. It was investigated that cold and hypoxic deep ocean water(DOW) could be uplifted to the euphotic layer, which could potentially change the nutrient distribution and adjust the N/P ratio. Both simulation and field experiments results confirmed that utilizing self-powered energy to inject compressed air to uplift DOW was a valid and efficient method. Therefore, further field-based research on artificial upwelling, especially for long-term field research is required to test the scientific hypothesis. | PAN YiWen FAN Wei ZHANG DaHai CHEN JiaWang HUANG HaoCai LIU ShuXia JIANG ZongPei DI YaNan TONG MengMeng CHEN Ying | 2016 | Science China Earth Sciences2016，59，2： | 3 |
| 2 | 2020 Roadmap on gas-involved photo-and electro-catalysis显示文摘Green reactions not only provide us chemical products without any pollution,but also offer us the viable technology to realize difficult tasks in normal conditions.Photo-,photoelectro-,and electrocatalytic reactions are indeed powerful tools to help us to embrace bright future.Especially,some gas-involved reactions are extremely useful to change our life environments from energy systems to liquid fuels and cost-effective products,such as H2 evolution(H2 production),02 evolution/reduction,CO2 reduction,N2 reduction(or N2 fixation) reactions.We can provide fuel cells clean H2 for electric vehicles from H2 evolution reaction(HER),at the same time,we also need highly efficient 02 reduction reaction(ORR) in fuel cells for improving the reaction kinetics.Moreover,we can get the clean oxidant O2 from water through O2 evolution reaction(OER),and carry out some reactions without posing any pollution to reaction systems.Furthermore,we can translate the greenhouse gas CO2 into useful liquid fuels through CO2 reduction reaction(CRR).Last but not the least,we can get ammonia from N2 reduction reaction(NRR),which can decrease energy input compared to the traditional Hubble process.These reactions,such as HER,ORR,OER,CRR and NRR could be realized through solar-,photoelectro-and electro-assisted ways.For them,the catalysts used play crucial roles in determining the efficiency and kinds of products,so we should consider the efficiency of catalysts.However,the cost,synthetic methods of catalysts should also be considered.Nowadays,significant progress has been achieved,however,many challenges still exist,reaction systems,catalysts underlying mechanisms,and so on.As extremely active fields,we should pay attention to them.Under the background,it has motivated us to contribute with a roadmap on ’GasInvolved Photo-and Electro-Catalysis’. | Yulu Yang Yang Tang Haomin Jiang Yongmei Chen Pingyu Wan Maohong Fan Rongrong Zhang Sana Ullah Lun Pan Ji-Jun Zou Mengmeng Lao Wenping Sun Chao Yang Gengfeng Zheng Qiling Peng Ting Wang Yonglan Luo Xuping Sun Alexander S.Konev Oleg V.Levin Panagiotis Lianos Zhuofeng Hu Zhurui Shen Qinglan Zhao Ying Wang Nadia Todorova Christos Trapalis Matthew V.Sheridan Haipeng Wang Ling Zhang Songmei Sun Wenzhong Wang Jianmin Ma | 2019 | Chinese Chemical Letters2019，30，12： | 1 |

| 4 | Feasibility assessment of up-flow anaerobic sludge blanket treatment of sulfamethoxazole pharmaceutical wastewater显示文摘Treatment of sulfamethoxazole pharmaceutical wastewater is a big challenge.In this study,a series of anaerobic evaluation tests on pharmaceutical wastewater from different operating units was conducted to evaluate the feasibility of using anaerobic digestion,and the results indicated that the key refractory factor for anaerobic treatment of this wastewater was the high sulfate concentration.A laboratory-scale up-flow anaerobic sludge blanket(UASB)reactor was operated for 195 days to investigate the effects of the influent chemical oxygen demand(COD),organic loading rate(OLR),and COD/SO_(4)^(2-) ratio on the biodegradation of sulfamethoxazole in pharmaceutical wastewater and the process performance.The electron flow indicated that methanogenesis was still the dominant reaction although sulfidogenesis was enhanced with a stepwise decrease in the influent COD/SO_(4)^(2-) ratio.For the treated sulfamethoxazole pharmaceutical wastewater,a COD of 4983 mg/L(diluted by 50%),OLR of 2.5 kg COD/(m^(3)·d),and COD/SO_(4)^(2-) ratio of more than 5 were suitable for practical applications.The recovery performance indicated that the system could resume operation quickly even if production was halted for a few days. | Yi Chen Shilong He Mengmeng Zhou Tingting Pan Yujia Xu Yingxin Gao Hengkang Wang | 2018 | Frontiers of Environmental Science & Engineering2018，12，5： | 1 |
| 5 | Robust hydrogel sensors for unsupervised learning enabled sign-to-verbal translation显示文摘Highly stretchable and robust strain sensors are rapidly emerging as promising candidates for a diverse of wearable electronics.The main challenge for the practical application of wearable electronics is the energy consumption and device aging.Energy consumption mainly depends on the conductivity of the sensor,and it is a key factor in determining device aging.Here,we design a liq-uid metal(LM)-embedded hydrogel as a sensing material to overcome the bar-rier of energy consumption and device aging of wearable electronics.The sensing material simultaneously exhibits high conductivity(up to 22 S m�1),low elastic modulus(23 kPa),and ultrahigh stretchability(1500%)with excel-lent robustness(consistent performance against 12000 mechanical cycling).A motion monitoring system is composed of intrinsically soft LM-embedded hydrogel as sensing material,a microcontroller,signal-processing circuits,Bluetooth transceiver,and self-organizing map developed software for the visu-alization of multi-dimensional data.This system integrating multiple functions including signal conditioning,processing,and wireless transmission achieves monitor hand gesture as well as sign-to-verbal translation.This approach provides an ideal strategy for deaf-mute communicating with normal people and broadens the application of wearable electronics. | Hude Ma Haiyang Qin Xiao Xiao Na Liu Shaolei Wang Junye Li Sophia Shen Shuqi Dai Mengmeng Sun Peiyi Li Xiaofang Pan Mingjun Huang Baoyang Lu Jun Chen Lidong Wu | 2023 | InfoMat2023，5，7： | 1 |
| 6 | Bioaugmentation of two-stage aerobic sequencing batch reactor with mixed strains for high nitrate nitrogen wastewater treatment显示文摘Mixed strains Delftia sp.YH01 and Acidovorax sp.YH02,with capability of heterotrophic nitrification-aerobic denitrification,were introduced into a two-stage aerobic sequencing batch reactor to enhance NO3^--N removal.With optimal C/N of 8,efficient NO3^--N removal was achieved at initial NO3^--N concentration of 2000 mg·L−1.Meanwhile,the massive accumulation of NO2^--N was avoided during the long operation.Compared to the one-stage aerobic sequencing batch reactor,the removal efficiency of NO3^--N and TN in the two-stage aerobic sequencing batch reactor was increased by 36.5% and 42.7%,which respectively was 93.8% and 88.4%.Microbial community study showed that the mixed strains have the stronger viability and can synergistically denitrify with the indigenous microorganisms in system,such as Azoarcus,Uncultured Saprospiraceae,Thauera,Paracocccus,which could be major contributors for aerobic denitrification.The proposed technology was shown to achieve high-efficiency treatment of high NO3^--N wastewater through aerobic denitrification. | Mengmeng Wang Gang Cao Naixian Feng Yongzhang Pan | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 1 |
| 7 | DRP1 deficiency induces mitochondrial dysfunction and oxidative stress-mediated apoptosis during porcine oocyte maturation显示文摘Background: Environmental pollution induces oxidative stress and apoptosis in mammalian oocytes, which can cause defects in reproduction;however, the molecular regulation of oxidative stress in oocytes is still largely unknown. In the present study, we identified that dynamin-related protein 1(DRP1) is an important molecule regulating oocyte mitochondrial function and preventing oxidative stress/apoptosis. DRP1 is a member of the dynamin GTPase superfamily localized at the mitochondrial-endoplasmic reticulum interaction site, where it regulates the fission of mitochondria and other related cellular processes.Results: Our results show that DRP1 was stably expressed during different stages of porcine oocyte meiosis, and might have a potential relationship with mitochondria as it exhibited similar localization. Loss of DRP1 activity caused failed porcine oocyte maturation and cumulus cell expansion, as well as defects in polar body extrusion.Further analysis indicated that a DRP1 deficiency caused mitochondrial dysfunction and induced oxidative stress,which was confirmed by increased reactive oxygen species levels. Moreover, the incidence of early apoptosis increased as detected by positive Annexin-V signaling.Conclusions: Taken together, our results indicate that DRP1 is essential for porcine oocyte maturation and that a DRP1 deficiency could induce mitochondrial dysfunction, oxidative stress, and apoptosis. | Haolin Zhang Zhennan Pan Jiaqian Ju Chunhua Xing Xiaohan Li Mengmeng Shan Shaochen Sun | 2021 | Journal of Animal Science and Biotechnology2021，12，1： | 1 |
| 8 | High-precision potassium isotope analysis using the Nu Sapphire collision cell(CC)-MC-ICP-MS显示文摘This study presents high-precision analyses of stable potassium(K)isotope ratio using the recently-developed,collision-cell multi-collector inductively coupled plasma mass spectrometry(CC-MC-ICP-MS,Nu Sapphire).The accuracy of our analyses is confirmed by measuring well-characterized geostandards(including rocks and seawater).Our results are consistent with literature values and a precision of 0.04‰(2SD)has been achieved based on multiple measurements of BCR-2 geostandard over a six-month period.We also evaluate factors that may lead to artificial isotope fractionations,including the mismatches in K concentration and acid molarity between samples and bracketing standards,as well as potential matrices.As the K adsorption capacity of AGW50-X8(200-400 mesh)is reduced with an increasing amount of matrix elements,less than 150µg K was loaded during the column chemistry.To evaluate the potential use of K isotopes as an archive of paleo seawater composition,δ^(41)K values of an international seawater standard(IAPSO),a Mn-nodule(NOD-P-1),and two iron formation standards(FeR-2 and FeR-4)are reported.The δ^(41)K value of IAPSO is consistent with other seawater samples reported previously,further substantiating a homogeneous K isotopic distribution in modern global oceans.The K isotopes in Mn-nodule(NOD-P-1:−0.121±0.013‰)and iron formation samples(FeR-2:−0.538±0.009‰;FeR-4:−0.401±0.008‰)seem to be an effective tracer of their formation genesis and compositional changes of ancient seawater.Our results suggest that high-precision measurements of stable K isotopes can be routinely obtained and open up a large variety of geological applications,such as continental weathering,hydrothermal circulation and alteration of oceanic crust. | Wenjun LI Mengmeng CUI Qiqi PAN Jing WANG Bingyu GAO Shanke LIU Meng YUAN Benxun SU Ye ZHAO Fang-Zhen TENG Guilin HAN | 2022 | Science China Earth Sciences2022，65，8： | 1 |
| 9 | High-throughput screening of SARS-CoV-2 main and papain-like protease inhibitors显示文摘The global COVID-19 coronavirus pandemic has infected over 109 million people,leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment.Here,we screened about 1.8 million small molecules against the main protease(M^(pro))and papain like protease(PL^(pro)),two major proteases in severe acute respiratory syndrome-coronavirus 2 genome,and identified 1851M^(pro)inhibitors and 205 PL^(pro)inhibitors with low nmol/l activity of the best hits.Among these inhibitors,eight small molecules showed dual inhibition effects on both M^(pro)and PL^(pro),exhibiting potential as better candidates for COVID-19 treatment.The best inhibitors of each protease were tested in antiviral assay,with over 40%of M^(pro)inhibitors and over 20%of PL^(pro)inhibitors showing high potency in viral inhibition with low cytotoxicity.The X-ray crystal structure of SARS-CoV-2 M^(pro)in complex with its potent inhibitor 4a was determined at 1.8Åresolution.Together with docking assays,our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development. | Yi Zang Mingbo Su Qingxing Wang Xi Cheng Wenru Zhang Yao Zhao Tong Chen Yingyan Jiang Qiang Shen Juan Du Qiuxiang Tan Peipei Wang Lixin Gao Zhenming Jin Mengmeng Zhang Cong Li Ya Zhu Bo Feng Bixi Tang Han Xie Ming-Wei Wang Mingyue Zheng Xiaoyan Pan Haitao Yang Yechun Xu Beili Wu Leike Zhang Zihe Rao Xiuna Yang Hualiang Jiang Gengfu Xiao Qiang Zhao Jia Li | 2023 | Protein & Cell2023，14，1： | 0 |
| 10 | On Instability of the Rayleigh–Bénard Problem without Thermal Diffusion in a Bounded Domain under L^(1)-Norm显示文摘We investigate the thermal instability of a three-dimensional Rayleigh–Bénard(RB for short)problem without thermal diffusion in a bounded domain.First we construct unstable solutions in exponential growth modes for the linear RB problem.Then we derive energy estimates for the nonlinear solutions by a method of a prior energy estimates,and establish a Gronwall-type energy inequality for the nonlinear solutions.Finally,we estimate for the error of L^(1)-norm between the both solutions of the linear and nonlinear problems,and prove the existence of escape times of nonlinear solutions.Thus we get the instability of nonlinear solutions under L^(1)-norm. | Pan Zhang Mengmeng Liu Fangying Song | 2022 | Annals of Applied Mathematics2022，38，3： | 0 |
| 11 | HfAlO-based ferroelectric memristors for artificial synaptic plasticity显示文摘Memristors have received much attention for their ability to achieve multi-level storage and synaptic learning.However,the main factor that hinders the application of memristors to simulate neural synapses is the instability of the formation and breakage of conductive filaments inside traditional memristors,which makes it difficult to simulate the function of biological synapses in practice.However,the resistance change of ferroelectric memristors relies on the polarization inversion of the ferroelectric thin film,thus avoiding the above problem.In this study,a Pd/HfAlO/LSMO/STO/Si ferroelectric memristor is proposed,which can achieve resistive switching properties through the combined action of ferroelectricity and oxygen vacancies.The I−V curves show that the device has good stability and uniformity.In addition,the effect of pulse sequence modulation on the conductance was investigated,and the biological synaptic function and learning behavior were simulated successfully.The results of the above studies provide a basis for the development of ferroelectric memristors with neurosynaptic-like behaviors. | Jie Yang Zixuan Jian Zhongrong Wang Jianhui Zhao Zhenyu Zhou Yong Sun Mengmeng Hao Linxia Wang Pan Liu Jingjuan Wang Yifei Pei Zhen Zhao Wei Wang Xiaobing Yan | 2023 | Frontiers of physics2023，18，6： | 0 |
| 12 | Berberine inhibits the proliferation of pancreatic cancer cells by targeting pancreatic cancer stem cells through regulating EMT signaling pathway显示文摘Pancreatic ductal adenocarcinoma(PDAC)is universally acknowledged as the cancer with the highest mortality rate.Berberine has high medicinal value and has been used as an anti-cancer agent.Hence the purpose of this study was to investigate the anti-cancer effect of berberine in PDAC.Berberine was shown to have a selective anti-cancer effect on PDAC by MTT assay in vitro.Pancreatic cancer stem cells(PCSCs),regulated by epithelial-mesenchymal transition(EMT),could promote the proliferation of PDAC cells.However,berberine suppressed the proliferation and stemness of PCSCs through immunofluorescence staining,stem cell sphere assays and so forth in vitro.In vivo,berberine reduced tumor size and decreased the expression levels of Ki67,a marker of cellular proliferation,in orthotopic pancreatic tumors.In addition,berberine inhibited the EMT signaling pathway by RT-PCR and Western blotting methods both in vitro and in vivo.Our study indicates that berberine inhibits the proliferation of PDAC cells both in vivo and in vitro.The mechanism of the anti-cancer effect of berberine likely involves the inhibition of EMT.Therefore,berberine may be a novel antineoplastic drug with clinical efficacy in PDAC. | MENGMENG LIU YUE PAN XUFENG TAO WENLI KANG YINGJIE LIU YONGJIE YANG GARY GUISHAN XIAO | 2022 | BIOCELL2022，46，10： | 0 |
| 13 | Guanine-assisted N-doped ordered mesoporous carbons as efficient capacity decaying suppression materials for lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)batteries are considered promising next-generation energy storage devices due to their high weight capacities and theoretical energy densities,which are significantly higher than those of conventional lithium-ion batteries.However,the sulfur cathode presents two major drawbacks,specifically low specific capacity caused by the poor electrical conductivities of the active materials and fast capacity decay caused by polysulfide dissolution/shuttling.Herein,a high-rate and high-stability dendritic material consisting of N-doped ordered mesoporous carbons(NOMCs)was successfully synthesized via a facile and low-cost calcination method.The highly ordered mesoporous carbon skeleton limited the growth of the sulfur nanofiller within its channels and provided the necessary electrical contact with the insulating sulfur.Furthermore,N-doped heteroatoms presented strong binding sites for trapping polysulfide intermediates,achieving high electrochemical activity,which promoted polysulfide conversion reactions.As a result,the prepared NOMC-2/S cathode material with 1.2-1.5 mg cm^(-2)of sulfur displayed excellent electrochemical performance with a high-rate capability of 460.5 m Ah g^(-1)at 1 C,a high specific capacity of 530.9 m Ah g^(-1)after 200 cycles at 0.1 C,and a decay rate of~0.19%per cycle. | Riguang Cheng Yanxun Guan Yumei Luo Chenchen Zhang Yongpeng Xia Sheng Wei Mengmeng Zhao Qi Lin Hao Li Shiyou Zheng Federico Rosei Lixian Sun Fen Xu Hongge Pan | 2022 | Journal of Materials Science & Technology2022，，6： | 0 |
| 14 | First-row transition metal compounds for aqueous metal ion batteries显示文摘In recent years,a series of aqueous metal ion batteries(AMIBs)has been developed to improve the safety and cost-efficiency of portable electronics and electric vehicles.However,the significant gaps in energy density,power density,and cycle stability of AMIBs directly hinder them from replacing the currently widely used non-aqueous metal ion batteries,which stems from the lack of reasonable configuration and performance optimization of electrode materials.First-row transition metal compounds(FRTMCs),with the advantages of optional voltage ranges(from low to high),adjustable crystal structures(layered and tunnel types with large spacing),and designable morphology(multi-dimensional nanostructures),are widely used to construct high-performance AMIBs.However,no comprehensive review papers were generated to highlight their specific and significant roles in AMIBs.In this review,we first summarize the superiority and characteristics of FRTMCs in AMIBs.Then,we put forward control strategies of FRTMCs from subsurface engineering to inner construction to promote capacitance control and diffusion control energy storage.After that,the electrochemical performance of the FRTMCs regulation strategies in AMIBs is reviewed.Finally,we present potential directions and challenges for further enhancements of FRTMCs in AMIBs.The review aims to provide an in-depth understanding of regulation strategies for enhancing energy storage to build high-performance AMIBs that meet practical applications. | Mengmeng Zhou Xinjun Huang Xiaomeng Tian Baohua Jia Hongge Pan Wenping Sun Qin Zhao Tianyi Ma | 2021 | Journal of Energy Chemistry2021，30，12： | 0 |
| 15 | Recent Progress of Fuel-Driven Temporary Materials显示文摘Fuel-driven dissipative self-assembly,which is a well-established concept in recent years,refers to out-of-equilibrium molecular self-assembly initiated and supported by the addition of active molecules (chemical fuel).It widely exists in nature since many temporary,active micro- or nanostructures in living bodies are generated by the dissipative self-assembly of biomolecules.Therefore,the study on dissipative self-assembly provides a good opportunity to have an insight into the microscopic mechanism of living organisms.In the meantime,dissipative assembly is thought to be a potential pathway to achieve dynamic,temporary supramolecular materials.Recently,a number of temporary materials have been developed with the aid of strategies for realizing dissipative self-assembly.Some of their properties,including solubility,stiffness,turbidity,color,or self-healing ability,change upon the addition of chemical fuel but spontaneously restore with chemical fuel consumption.The dynamic of these materials brings them various unprecedented functions.In this review,the principles of fabricating a fuel-driven temporary material are first reviewed.Subsequently,recent examples of fuel-driven temporary materials are emphatically summarized,including gels,self-erased inks,nanoreactors,self-healing materials,nanochannels,and droplets.Finally,the challenges of developing fuel-driven temporary materials and some perspectives on the function and application of such kind of materials are discussed. | Guangtong Wang Mengmeng Nan Kangle Guo Yaqi Pan Tao Jia Shaoqin Liu | 2023 | Chinese Journal of Chemistry2023，41，23： | 0 |
| 16 | Click CAR-T cell engineering for robustly boosting cell immunotherapy in blood and subcutaneous xenograft tumor显示文摘The adoptive transfer of chimeric antigen receptor-T(CAR-T)cells has shown remarkable clinical responses in hematologic malignancies.However,unsatisfactory curative results and side effects for tumor treatment are still unsolved problems.Herein we develop a click CAR-T cell engineering strategy via cell glycometabolic labeling for robustly boosting their antitumor effects and safety in vivo.Briefly,paired chemical groups(N3/BCN)are separately incorporated into CAR-T cell and tumor via nondestructive intrinsic glycometabolism of exogenous Ac4GalNAz and Ac4ManNBCN,serving as an artificial ligand-receptor.Functional groups anchored on cell surface strengthen the interaction of CAR-T cell and tumor via bioorthogonal click chemistry,further enhancing specific recognition,migration and selective antitumor effects of CAR-T cells.In vivo,click CAR-T cell completely removes lymphoma cells and minimizes off-target toxicity via selective and efficient bioorthogonal targeting in blood cancer.Surprisingly,compared to unlabeled cells,artificial bioorthogonal targeting significantly promotes the accumulation,deep penetration and homing of CAR-T cells into tumor tissues,ultimately improving its curative effect for solid tumor.Click CAR-T cell engineering robustly boosts selective recognition and antitumor capabilities of CAR T cells in vitro and in vivo,thereby holding a great potential for effective clinical cell immunotherapy with avoiding adverse events in patients. | Hong Pan Wenjun Li Ze Chen Yingmei Luo Wei He Mengmeng Wang Xiaofan Tang Huamei He Lanlan Liu Mingbin Zheng Xin Jiang Ting Yin Ruijing Liang Yifan Ma Lintao Cai | 2021 | Bioactive Materials2021，6，4： | 0 |
| 17 | Transcriptome analysis reveals tumor antigen and immune subtypes of melanoma显示文摘Purpose:To screen potential tumor antigens for melanoma vaccine development and identify different immune subtypes.Methods:Transcriptional data(HTSEQ-FPKM)and clinical information of a 472 Melanoma cohort GDC TCGA Melanoma(SKCM)were downloaded from the UCSC XENA website(http://gffzz797b50e9334d4ed4hwbobbp0wkuqn6q60.ffgz.tsg.suse.edu.cn/).Subsequently,transcriptome data and clinical information of 210 melanoma cohort GSE65904 were downloaded from Gene Expression Omnibus(GEO),a large global public database.All the transcriptome expression data matrices were log2 transformed for subsequent analysis.GEPIA,TIMER,and IMMPORT databases are also used for analysis.Cell function experiments were performed to validate the role of the IDO1 gene in melanoma cell line A375.Results:Our study provides potential tumor antigens for vaccine development in melanoma patients:GZMB,GBP4,CD79A,APOBEC3F,IDO1,JCHAIN,LAG3,PLA2G2D,XCL2.In addition,we divide melanoma patients into two immune subtypes that have significant differences in tumor immunity and may have different responses to vaccination.In view of the unclear role of IDO1 in melanoma,we selected IDO1 for cell assay validation.Cell function assay showed that IDO1 was significantly overexpressed in the melanoma A375 cell line.After IDO1 knockdown,the activity,invasion,migration and healing ability of A375 cell lines were significantly decreased.Conclusion:Our study could provide a reference for the development of vaccines for melanoma patients. | JIAHENG XIE MENGMENG OU PAN YU DAN WU QIKAI TANG YUAN CAO JING HANG LU YIN TINGHONG XIANG MING WANG JINGPING SHI | 2023 | Oncology Research2023，31，3： | 0 |
| 18 | Control strategies for disinfection byproducts by ion exchange resin,nanofiltration and their sequential combination显示文摘Disinfection byproducts (DBPs) are emerging pollutants in drinking water with high health risks. Precursor reduction before disinfection is an effective strategy to control the formation of DBPs. In this study, three types of anion exchange resins (AERs) and two types of nanofiltration (NF) membranes were tested for their control effects on DBP precursors, DBPs, and total organic halogen (TOX). The results showed that, for AER adsorption, the removal efficiencies of DBP precursors, DBPs, and TOX increased with the increase of resin dose, and the strong basic macroporous anion exchange resin (M500MB) had the highest removal efficiencies. For NF, the highest removal efficiencies were achieved at an operating pressure of 4 bar, and the membrane (NF90) with a smaller molecular weight cut-off, had a better control efficiency. However, AER adsorption was inefficient in removing dissolved organic carbon (DOC);NF was inefficient in removing Br− resulting in insufficient control of Br-DBPs. Accordingly, a sequential approach of AER (M500MB) adsorption followed by NF (NF90) was developed to enhance the control efficiency of DBPs. Compared with single AER adsorption and single NF, the sequential approach further increased the removal efficiencies of DOC by 19.4%–101.9%, coupled with the high Br− removal efficiency of 92%, and thus improved the reduction of cyclic DBPs and TOX by 3.5%–4.9%, and 2.4%–8.4%, respectively;the sequential approach also reduced the cytotoxicity of the water sample by 66.4%. | Yufeng Liao Mengmeng Tang Mengyuan Li Peng Shi Aimin Li Yangyang Zhang Yang Pan | 2023 | Frontiers of Environmental Science & Engineering2023，17，10： | 0 |
| 19 | Unprecedent green macroalgae bloom:mechanism and implication to disaster prediction and prevention显示文摘Green macroalgae bloom(GMB),with the dominant species of Ulva prolifera,has regularly occurred since 2007 along the China coast.Although disaster prevention and control achieved favorable results in 2020,the satellite-observed GMB annual maximum coverage(AMC)rebounded sharply in 2021 to an unprecedented level.The reasons for this rebound and the significant interannual variability over past 15 years are still open questions.Here,by using long-term time-series(2007-2022)optical and Synthetic Aperture Radar satellite observations(1000+scenes),meteorological data and water quality statistics,the mechanism analysis was performed by exploring effects from natural factors and human activities.Two key determinants for AMC are successfully identified from numerous potential factors which are the macroalgae distribution in a key area(the Subei Shoal)during a critical period(from April to May 20)and the nutrient availability.Furthermore,by using these two parameters,a novel model for AMC prediction(R^(2)=0.87,p<0.01)is proposed and independently validated,which can reasonably explain the significant interannual variability(2014-2021)and agree well with the latest observation in 2022(percentage difference 12%).Finally,suggestions are proposed for future disaster prevention and alleviation.This work may aid future bloom prediction and management measure optimization. | Mengmeng Cao Xuyan Li Tingwei Cui Xinliang Pan Yan Li Yanlong Chen Ning Wang Yanfang Xiao Xingai Song Yuzhu Xu Runa A Bing Mu Song Qing Rongjie Liu Wenjing Zhao Yuhai Bao Jie Zhang Lan Wei | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 20 | Deciphering the effect of sodium dodecylbenzene sulfonate on up-flow anaerobic sludge blanket treatment of synthetic sulfate-containing wastewater显示文摘In this study,the effects of organic sulfur on anaerobic biological processes were investigated by operating two up-flow anaerobic sludge blanket(UASB)reactors with sodium dodecylbenzene sulfonate(SDBS)as a representative of organic sulfur.The results indicated that the specific methanogenic activity(SMA)and chemical oxygen demand(COD)removal efficiency of R2(with SDBS added)were higher than those of R1(without SDBS)when the COD/SO_(4)^(2−)ratio was above 5.0.However,when the COD/SO_(4)^(2−)ratio was lower than 5.0,the sulfate reduction efficiency of R2 was higher than that of R1.These results and the observed SDBS transformation efficiency in anaerobic reactors indicate that low concentrations of SDBS accelerate methane production and the continuous accumulation of SDBS does not weaken the reduction of sulfate.Similarly,the calculated electron flux for a COD/SO_(4)^(2−)ratio of 1.0 indicates that the utilization intensity of electrons by sulfate-reducing bacteria(SRB)in R2 was 36.48%higher than that of SRB in R1 and exceeded that of methane-producing archaea(MPA)under identical working conditions.Moreover,the addition of SDBS in R2 made sulfidogenesis the dominant reaction at low COD/SO_(4)^(2−),and Methanobacterium and Methanobrevibacter with H_(2)/CO_(2)as the substrate and Desulfomicrobium were the dominant MPA and SRB,respectively.However,methanogenesis was still the dominant reaction in R1,and Methanosaeta with acetic acid as the substrate and Desulfovibrio were the dominant MPA and SRB,respectively. | Ruijie Li Mengmeng Zhou Shilong He Tingting Pan Jing Liu Jiabao Zhu | 2021 | Frontiers of Environmental Science & Engineering2021，15，5： | 0 |
