| 1 | Monovalent cation perm-selective membranes(MCPMs)'New developments and perspectives显示文摘As one of the most typical and promising membrane processes, electrodialysis(ED) technique plays a more and more significant role in industrial separation. Especially, the separation of monovalent cations and multivalent cations is currently a hot topic, which is not only desirable for many industries but also challenging for academic explorations. The main aim of the present contribution is to view the advances of a wide variety of monovalent cation perm-selective membranes(MCPMs) and their preparation technologies including(1) covalent crosslinking,(2) surface modification,(3) polymer blending,(4) electrospinning,(5) nanofiltration alike membrane,and(6) organic–inorganic hybrid. The relevant advantages and disadvantages with respect to some specific cases have been discussed and compared in detail. Furthermore, we elaborately discuss the opportunities and challenges of MCPMs, the fabricating strategies to take and the future perspectives. | Liang Ge Bin Wu Dongbo Yu Abhishek N.Mondal Linxiao Hou Noor U1 Afsar Qiuhua Li Tingting Xu Jibin Miao Tongwen Xu | 2017 | Chinese Journal of Chemical Engineering2017，25，11： | 8 |

| 3 | Performance of BCC-CSM Models with Different Horizontal Resolutions in Simulating Extreme Climate Events in China显示文摘In this study,the performance of the Beijing Climate Center(BCC)Climate System Model version 1.1(BCCCSM1.1)(280-km resolution)and the BCC-CSM1.1 m(110-km resolution)in simulating extreme climate events over China in the last 40 years is compared.Both models capture the main spatial distribution features of heavy precipitation(R95T),the number of consecutive wet days(CWD),the annual count of days with precipitation≥1 mm(R1),the maximum consecutive 5-day precipitation(Rx5),and the numbers of frost days(FD)and summer days(SU).The BCC-CSM1.1 m has a better ability to simulate the detailed distribution of extreme climate events than the BCCCSM1.1,including R95T,CWD,R1,and the simple precipitation intensity index(SDII).However,the BCCCSM 1.1 m does not show an improvement in simulating the number of days with extreme precipitation(R90N),the number of consecutive dry days(CDD),the heat wave duration index(HWDI),the warm day frequency(TX90 P),and cold night frequency(TN10P).This indicates that the simulation of the R95T,CWD,R1,and SDII climate events is more sensitive to the resolution of the model.The improved BCC-CSM1.1 m is used to explore the projection of extreme climate change in China during the 21 st century under the RCP4.5(Representative Concentration Pathways)and RCP8.5 scenarios.The results show that extreme precipitation will increase dramatically over North and Southwest China in the late 21 st century.The CWD index will decrease on the Tibetan Plateau and in northeastern and central China and will increase in other parts of China;R1 will increase in northern China and decrease in southern China;Rx5 will increase dramatically in southern China;FD will decrease and SU will increase over China in the late 21 st century under both emission scenarios,with larger amplitudes in RCP8.5. | Linxiao WEI Xiaoge XIN Chan XIAO Yonghua LI Yao WU Hongyu TANG | 2019 | Journal of Meteorological Research2019，33，4： | 3 |
| 4 | Genesis of Geothermal Fluid in Typical Geothermal Fields in Western Sichuan,China显示文摘The hydrogeochemical characteristics of geothermal fluids can reveal the genesis of geothermal systems and act as important references for developing and using geothermal resources.This study presents hydrogeochemical processes and thermal cycle mechanisms of typical geothermal fields in Western Sichuan.Based on the geological conditions in Western Sichuan,29 hot springs in three geothermal fields in the Batang and Litang areas were selected for hydrochemical and isotopic(δD andδ18O)analyses.Furthermore,the temperature of the thermal reservoir was calculated and the upflow cooling process of the hot springs was analyzed.Most of the subterranean hot waters in Batang and Litang are of the HCO3-Na hydrochemical type.The ion variation in Batang is primarily affected by water-rock interactions.There is a strong positive correlation between Na+,B?,and Cl?in Litang,suggesting that they have the same material source.The Na+and metaboric acid content is relatively high,which indicates that the groundwater runoff in both areas is relatively long-lasting,with reduced flow velocity;moreover,the metasilicic acid content is relatively high,which supports this conclusion.Both hydrogen and oxygen isotopes plot near the atmospheric precipitation line,indicating that groundwater recharge is functionally obtained from precipitation.The calculated thermal storage temperatures in Batang and Litang were 88–199℃ and 96–154℃,respectively.The proportion of cold water mixing in Batang was 64%–67%,while that in Litang was 60%–68%.According to the calculated results,the initial thermal cycle depth of the Batang area(4540–4780 m)was greater than that of the Litang area(3150–3960 m).The enthalpy of the deep parental geothermal fluid in Batang was 1550 J/g with a Cl^(-)concentration of 37 mg/L,while that in Litang was 2100 J/g with a Cl^(-)concentration of 48 mg/L. | ZHAO Jiayi WANG Guiling ZHANG Cuiyun XING Linxiao LI Man ZHANG Wei | 2021 | Acta Geologica Sinica(English Edition)2021，95，3： | 2 |
| 5 | Error suppression techniques for energy-efficient high-resolution SAR ADCs显示文摘The successive approximation register(SAR)is one of the most energy-efficient analog-to-digital converter(ADC)architecture for medium-resolution applications.However,its high energy efficiency quickly diminishes when the target resolution increases.This is because a SAR ADC suffers from several major error source,including the sampling kT/C noise,the comparator noise,and the DAC mismatch.These errors are increasing hard to address in high-resolution SAR ADCs.This paper reviews recent advances on error suppression techniques for SAR ADCs,including the sampling kT/C noise reduction,the noise-shaping(NS)SAR,and the mismatch error shaping(MES).These techniques aim to boost the resolution of SAR ADCs while maintaining their superior energy efficiency. | Jiaxin Liu Xiyuan Tang Linxiao Shen Shaolan Li Zhelu Li Wenjuan Guo Nan Sun | 2020 | Journal of Semiconductors2020，41，11： | 2 |
| 6 | Iron-doxorubicin prodrug loaded liposome nanogenerator programs multimodal ferroptosis for efficient cancer therapy显示文摘Ferroptosis is a new mode of cell death,which can be induced by Fenton reactionmediated lipid peroxidation.However,the insufficient H2O2 and high GSH in tumor cells restrict the efficiency of Fenton reaction-dependent ferroptosis.Herein,a self-supplying lipid peroxide nanoreactor was developed to co-delivery of doxorubicin(DOX),iron and unsaturated lipid for efficient ferroptosis.By leveraging the coordination effect between DOX and Fe3+,trisulfide bond-bridged DOX dimeric prodrug was actively loaded into the core of the unsaturated lipids-rich liposome via iron ion gradient method.First,Fe3+could react with the overexpressed GSH in tumor cells,inducing the GSH depletion and Fe2+generation.Second,the cleavage of trisulfide bond could also consume GSH,and the released DOX induces the generation of H2O2,which would react with the generated Fe2+in step one to induce efficient Fenton reaction-dependent ferroptosis.Third,the formed Fe3+/Fe2+couple could directly catalyze peroxidation of unsaturated lipids to boost Fenton reaction-independent ferroptosis.This iron-prodrug liposome nanoreactor precisely programs multimodal ferroptosis by integrating GSH depletion,ROS generation and lipid peroxidation,providing new sights for efficient cancer therapy. | Yinxian Yang Shiyi Zuo Linxiao Li Xiao Kuang Jinbo Li Bingjun Sun Shujun Wang Zhonggui He Jin Sun | 2021 | Asian Journal of Pharmaceutical Sciences2021，16，6： | 1 |
| 7 | Evaluation and Projection of Extreme High Temperature Indices in Southwestern China Using NEX-GDDP-CMIP6显示文摘Based on the recently released NASA Earth Exchange Global Daily Downscaled Projections(NEX-GDDP)Coupled Model Intercomparison Project Phase 6(CMIP6) dataset and the gridded observational daily dataset CN05.1, this study evaluates the performance of 26 CMIP6 models in simulating extreme high temperature(EHT) indices in southwestern China and estimates future changes in the EHT indices under the Shared Socioeconomic Pathways(SSPs) SSP1-2.6, SSP2-4.5, and SSP5-8.5 using 11 optimal CMIP6 models. Five EHT indices are employed:annual maximum value of daily maximum temperature(TXX), high temperature days(T35), warm days(TX90P),heat wave frequency(HWF), and heat wave days(HWD). The main results are as follows.(1) NEX-GDDP-CMIP6 is highly capable of simulating the spatial patterns of TXX and T35 in southwestern China but it presents a weaker ability to simulate the spatial patterns of TX90P, HWF, and HWD.(2) The simulated time series of T35, TX90P, HWF,and HWD in southwestern China exhibit consistent upward trends with the observations. The linear trends of increase in TX90P and HWD are much greater than those of increase in TXX, T35, and HWF.(3) The estimated increases in TXX and T35 in southwestern China are significantly greater in Chongqing and the adjacent areas of Sichuan than in the other regions. Spatial distributions of the increases in TX90P, HWF, and HWD generally show higher values in the west and lower values in the east.(4) In the three different scenarios, the projected future TXX,T35, TX90P, and HWD in southwestern China all display a continuous increase with time and radiative forcing levels, whereas HWF initially increases but then decreases under the SSP5-8.5 scenario. By the end of the 21st century, under the SSP5-8.5 scenario, TXX and T35 are projected to increase by 6.0℃ and 45.0 days, respectively. The duration of individual heat waves is also expected to increase. | Fen ZHANG Linxiao WEI Yonghua LI Hongyu TANG Tianyu ZHANG Baogang YANG | 2024 | Journal of Meteorological Research2024，38，1： | 0 |

| 10 | Temporal Integrative Omics Reveals an Increase in Nondegradative Ubiquitylation during Primary Hepatocyte Dedifferentiation显示文摘Primary hepatocytes(PHCs)are widely used in various fields,but the progressive deterioration of liverspecific features in vitro significantly limits their application.While the transcriptional regulation and whole cell proteome(WCP)of PHCs have been extensively studied,only a small number of studies have addressed the role of posttranslational modifications in this process.To elucidate the underlying mechanisms that induce dedifferentiation,we carried out parallel quantifications of the transcriptome,WCP,ubiquitinome,and phosphoproteome of rat PHCs after 0,6,12,24,and 48 h of in vitro culture.Our data constitute a detailed proteomic analysis of dedifferentiated PHCs including 2196 proteins,2056 ubiquitinated sites,and 4932 phosphorylated peptides.We revealed a low correlation between the transcriptome and WCP during dedifferentiation.A combined analysis of the ubiquitinome with the corresponding WCP indicated that the dedifferentiation of PHCs led to an increase in nondegradative K27 ubiquitination.Functional analysis of the altered phosphoproteins suggested a significant enrichment in ferroptosis.In all,404 proteins with both ubiquitination and phosphorylation were identified to be involved in critical metabolic events.Furthermore,Ptbph Hnqjd,Hnrnpu,and Srrm2 were identified as hub genes.Taken together,our data provide new insights into proteome dynamics during PHC dedifferentiation and potential targets to inhibit the dedifferentiation process. | Zhengyi Jiang Zeyu Sun Xiaoxi Ouyang Yalei Zhao Menghao Zhou Baohong Wang Qirui Li Linxiao Fan Sainan Zhang Lanjuan Li | 2020 | Engineering2020，6，11： | 0 |
