1Predicting Cadmium Safety Thresholds in Soils Based on Cadmium Uptake by Chinese Cabbage显示文摘Cadmium(Cd), a common toxic heavy metal in soil, has relatively high bioavailability, which seriously threatens agricultural products. In this study, 8 different soils with contrasting soil properties were collected from different regions in China to investigate the Cd transfer coefficient from soil to Chinese cabbage(Brassica chinensis L.) and the threshold levels of Cd in soils for production of Chinese cabbage according to the food safety standard for Cd. Exogenous Cd(0–4 mg kg^(-1)) was added to the soils and equilibrated for 2 weeks before Chinese cabbage was grown under greenhouse conditions. The influence of soil properties on the relationship between soil and cabbage Cd concentrations was investigated. The results showed that Cd concentration in the edible part of Chinese cabbage increased linearly with soil Cd concentration in 5 soils, but showed a curvilinear pattern with a plateau at the highest dose of exogenous Cd in the other 3 soils. The Cd transfer coefficient from soil to plant varied significantly among the different soils and decreased with increasing soil p H from 4.7 to 7.5. However, further increase in soil pH to > 8.0 resulted in a significant decrease in the Cd transfer coefficient. According to the measured Cd transfer coefficient and by reference to the National Food Safety Standards of China, the safety threshold of Cd concentration in soil was predicted to be between 0.12 and 1.7 mg kg^(-1) for the tested soils. The predicted threshold values were higher than the current soil quality standard for Cd in 5 soils, but lower than the standard in the other 3 soils. Regression analysis showed a significant positive relationship between the predicted soil Cd safety threshold value and soil p H in combination with soil organic matter or clay content.LU Junhe YANG Xinping MENG Xuchao WANG Guoqing LIN Yusuo WANG Yujun ZHAO Fangjie 2017Pedosphere2017,27,3:13
2Preparation and CO2 adsorption properties of porous carbon by hydrothermal carbonization of tree leaves显示文摘Porous carbon materials were prepared by hydrothermal carbonization(HTC) and KOH activation of camphor leaves and camellia leaves. The morphology, pore structure, chemical properties and CO2 capture ability of the porous carbon prepared from the two leaves were compared. The effect of HTC temperature on the structure and CO2 adsorption properties was especially investigated. It was found that HTC temperature had a major effect on the structure of the product and the ability to capture CO2. The porous carbon materials prepared from camellia leaves at the HTC temperature of 240℃ had the highest proportion of microporous structure, the largest specific surface area(up to 1823.77m^2/g) and the maximum CO2 adsorption capacity of 8.30mmol/g at 25℃ under 0.4 MPa. For all prepared porous carbons, simulation results of isothermal adsorption model showed that Langmuir isotherm model described the adsorption equilibrium data better than Freundlich isotherm model. For porous carbons prepared from camphor leaves, pseudo-first order kinetic model was well fitted with the experimental data. However,for porous carbons prepared from camellia leaves, both pseudo-first and pseudo-second order kinetics model adsorption behaviors were present. The porous carbon materials prepared from tree leaves provided a feasible option for CO2 capture with low cost, environmental friendship and high capture capability.Guangzhi Yang Shen Song Jing Li Zhihong Tang Jinyu Ye Junhe Yang 2019Journal of Materials Science & Technology2019,35,5:8
3Micro-droplet Digital Polymerase Chain Reaction and Real-Time Quantitative Polymerase Chain Reaction Technologies Provide Highly Sensitive and Accurate Detection of Zika Virus显示文摘The establishment of highly sensitive diagnostic methods is critical in the early diagnosis and control of Zika virus(ZIKV)and in preventing serious neurological complications of ZIKV infection. In this study, we established micro-droplet digital polymerase chain reaction(ddPCR) and real-time quantitative PCR(RT-qPCR) protocols for the detection of ZIKV based on the amplification of the NS5 gene. For the ZIKV standard plasmid, the RT-qPCR results showed that the cycle threshold(Ct) value was linear from 10~1 to 10~8 copy/l L, with a standard curve R^2 of 0.999 and amplification efficiency of 92.203%;however, a concentration as low as 1 copy/l L could not be detected. In comparison with RT-qPCR, the dd PCR method resulted in a linear range of 10~1–10~4 copy/l L and was able to detect concentrations as low as 1 copy/l L. Thus, for detecting ZIKV from clinical samples, RT-qPCR is a better choice for high-concentration samples(above 10~1 copy/l L),while ddPCR has excellent accuracy and sensitivity for low-concentration samples. These results indicate that the ddPCR method should be of considerable use in the early diagnosis, laboratory study, and monitoring of ZIKV.Yuan Hui Zhiming Wu Zhiran Qin Li Zhu Junhe Liang Xujuan Li Hanmin Fu Shiyu Feng Jianhai Yu Xiaoen He Weizhi Lu Weiwei Xiao Qinghua Wu Bao Zhang Wei Zhao 2018Virologica Sinica2018,33,3:6
4Characterization of the start-up behavior and steady-state performance of biotrickling filter removing low concentration toluene waste gas显示文摘A biotrickling filter packed with the regular ceramic spheres was designed and fabricated to purify the low toluene-concentration waste gas.Particular attention was made to the study of the start-up behavior of the biotrickling filter.Moreover,the steady performances were investigated to establish the experimental correlation between the operation factors and removal efficiency.It was found that the start-up process of the biotrickling filter exhibited three stages including the biofilm formation,biofilm development,and biofilm stabilization.The OD600 nm of the circulated liquid,gas pressure drop,elimination capacity,and temperature rise maintained at a rather low level in the biofilm formation stage,then increased rapidly in the biofilm development stage,and finally reached a stable value in the biofilm stabilization stage.It was also found that the removal efficiency of the biotrickling filter in the stable period decreased with increase in the waste gas flow rate,circulated liquid flow rate,and diameter of the ceramic sphere.More interestingly,it was revealed the operation modes have a significant influence on the removal efficiency of the biotrickling filter,and the microorganism show a high activity under the operating temperature ranging from 30°C to 40°C.The experimental correlations for describing the effect of operation factors on the removal efficiency of the biotrickling filters under both the co-current and counter-current operation modes were obtained.The correlation results are in good agreement with the experimental data.CHEN Rong LIAO Qiang TIAN Xin WANG YongZhong ZHU Xun MIAO JunHe 2012Science China(Technological Sciences)2012,55,6:4
5Thermally stable photoluminescence and long persistent luminescence of Ca3Ga4O9:Tb^3+/Zn^2+显示文摘A green long persistent luminescence(LPL) phosphor Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) was prepared. Ca_3 Ga_4 O_9 matrix exhibits blue self-activated LPL due to the creation of intrinsic traps. When Tb3+ is doped, the photoluminescence(PL) and LPL colors change from blue to green with their intensities significantly enhanced. The doping of Zn^(2+) evidently improves the PL and LPL performances of the Ca_3Ga_4O_9 matrix and Ca_3Ga_4O_9:Tb^(3+). The thermoluminescence(TL) spectra show that a successive trap distribution is formed by multiple intrinsic traps with different depths in the Ca_3 Ga_4 O_9 matrix, and the incorporation of Tb^(3+) and Zn^(2+) effectively increases the densities of these intrinsic traps. The existence of a successive trap distribution makes the Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) phosphor exhibit thermally stable PL and LPL, It is indicated that this phosphor shows great promise for the application such as high-temperature LPL phosphor.Zhangwen Long Junhe Zhou Jianbei Qiu Qi Wang Dacheng Zhou Xuhui Xu Xue Yu Hao Wu Zhencai Li 2018Journal of Rare Earths2018,36,7:4
6“All‐In‐One” integrated ultrathin SnS2@3D multichannel carbon matrix power high‐areal–capacity lithium battery anode显示文摘Construction of a thickness‐independent electrode with high active material mass loading is crucial for the development of high energy rechargeable lithium battery.Herein,we fabricate an all‐in‐one integrated SnS2@3D multichannel carbon matrix(SnS2@3DMCM)electrode with in‐situ growth of ultrathin SnS2 nanosheets inside the inner walls of three dimensional(3D)multichannels.The interconnected conductive carbon matrix derived from natural wood acts as an integrated porous current collector to avail the electrons transport and accommodate massive SnS2 nanosheets,while plenty of 3D aligned multichannels facilitate fast ions transport with electrode thickness‐independent even under high mass loading.As expected,the integrated SnS2@3DMCM electrode exhibits remarkable electrochemical lithium storage performance,such as exceptional high‐areal‐capacity of 6.4 mAh cm−2,high rate capability of 3 mAh cm−2 under current of 6.8 mAcm−2(10 C),and stable cycling performance of 6.8 mAcm−2 with a high mass loading of 7mg cm−2.The 3D integrated porous electrode constructing conveniently with the natural source paves new avenues towards future high‐performance lithium batteries.Hongyi Xu Chengxin Peng Yuhua Yan Fei Dong Hao Sun Junhe Yang Shiyou Zheng 2019Carbon Energy2019,1,2:4
7Homologous Strategy to Construct High‑Performance Coupling Electrodes for Advanced Potassium‑Ion Hybrid Capacitors显示文摘Potassium-ion hybrid capacitors(PIHCs)have been considered as promising potentials in mid-to large-scale storage system applications owing to their high energy and power density.However,the process involving the intercalation of K+into the carbonaceous anode is a sluggish reaction,while the adsorption of anions onto the cathode surface is relatively faster,resulting in an inability to exploit the advantage of high energy.To achieve a high-performance PIHC,it is critical to promote the K^+insertion/desertion in anodic materials and design suitable cathodic materials matching the anodes.In this study,we propose a facile“homologous strategy”to construct suitable anode and cathode for high-performance PIHCs,that is,unique multichannel carbon fiber(MCCF)-based anode and cathode materials are firstly prepared by electrospinning,and then followed by sulfur doping and KOH activation treatment,respectively.Owing to a multichannel structure with a large interlayer spacing for introducing S in the sulfur-doped multichannel carbon fiber(S-MCCF)composite,it presents high capacity,super rate capability,and long cycle stability as an anode in potassium-ion cells.The cathode composite of activated multichannel carbon fiber(aMCCF)has a considerably high specific surface area of 1445 m^2 g^−1 and exhibits outstanding capacitive performance.In particular,benefiting from advantages of the fabricated S-MCCF anode and aMCCF cathode by homologous strategy,PIHCs assembled with the unique MCCF-based anode and cathode show outstanding electrochemical performance,which can deliver high energy and power densities(100 Wh kg^−1 at 200 W kg^−1,and 58.3 Wh kg^−1 at 10,000 W kg^−1)and simultaneously exhibit superior cycling stability(90%capacity retention over 7000 cycles at 1.0 A g^−1).The excellent electrochemical performance of the MCCF-based composites for PIHC electrodes combined with their simple construction renders such materials attractive for further in-depth investigations of alkali-ion battery and capacitor applications.Ying Xu Jiafeng Ruan Yuepeng Pang Hao Sun Chu Liang Haiwen Li Junhe Yang Shiyou Zheng 2021Nano-Micro Letters2021,13,1:3
8Electrolyte/Electrode Interfaces in All‑Solid‑State Lithium Batteries:A Review显示文摘All-solid-state lithium batteries are promising next-generation energy storage devices that have gained increasing attention in the past decades due to their huge potential towards higher energy density and safety.As a key component,solid electrolytes have also attracted significant attention and have experienced major breakthroughs,especially in terms of Li-ion conductivity.However,the poor electrode compatibility of solid electrolytes can lead to the degradation of electrolyte/electrode interfaces,which is the major cause for failure in all-solid-state lithium batteries.To address this,this review will summarize the indepth understanding of physical and chemical interactions between electrolytes and electrodes with a focus on the contact,charge transfer and Li dendrite formation occurring at electrolyte/electrode interfaces.Based on mechanistic analyses,this review will also briefly present corresponding strategies to enhance electrolyte/electrode interfaces through compositional modifications and structural designs.Overall,the comprehensive insights into electrolyte/electrode interfaces provided by this review can guide the future investigation of all-solid-state lithium batteries.Yuepeng Pang Jinyu Pan Junhe Yang Shiyou Zheng Chunsheng Wang 2021Electrochemical Energy Reviews2021,4,2:3

10Effects of Fenvalerate on Steroidogenesis in Cultured Rat Granulosa Cells显示文摘Objective This study was designed to examine the in vitro effects of fenvalerate on steroid production and steroidogenic enzymes mRNA expression level in rat granulosa cells. Methods Using primary cultured rat granulosa cells (rGCs) as model, fenvalerate of various concentrations (0, 1, 5, 25, 125, 625 μmol/L) was added to the medium for 24 h. In some cases, optimal concentrations of 22(R)-hydroxycholesterol (25 μmol/L), Follicle stimulating hormone (FSH, 2 mg/L), or 8-Bromo-cAMP (1 mmol/L) were provided. Concentrations of 17β-estradiol(E2) and progesterone (P4) in the medium from the same culture wells were measured by RIA and the steroidogenic enzyme mRNA level was quantified by semi-quantitative RT-PCR. Results Fenvalerate decreased both P4 and E2 production in a dose-dependent manner while it could significantly stimulate rGCs proliferation. This inhibition was stronger in the presence of FSH. Furthermore, it could not be reversed by 22(R)-hydroxycholesterol or 8-Bromo-cAMP. RT-PCR revealed that fenvalerate had no significant effect on 3β-HSD, but could increase the P450scc mRNA level. In addition, 17β-HSD mRNA level was dramatically reduced with the increase of fenvalerate dose after 24 h treatment. Conclusion Fenvalerate inhibits both P4 and E2 production in rGCs. These results support the view that fenvalerate is considered as a kind of endocrine-disrupting chemicals. The mechanism of its disruption may involve the effects on steroidogenesis signaling cascades and/or steroidogenic enzyme’s activity.JIAN-FENGCHEN HAI-YANCHEN RULIU JUNHE LINSONG QIANBIAN LI-CHUNXU JIAN-WEIZHOU HANGXIAO GUI-DONGDAI XIN-RUWANG 2005Biomedical and Environmental Sciences2005,18,2:2

17Engineering CoMoO_(4) in reduced graphene oxide as superior cathode hosts for advanced room-temperature sodium-sulfur batteries显示文摘Promising room-temperature sodium-sulfur(RT Na-S)battery systems rely on purposely designed highperforming and low-cost electrode materials.Nevertheless,there are the challenges of irreversible dissolution and slow redox kinetics of NaPSs in the complete discharge of sulfur capacity.Herein,engineered CoMoO_(4)in reduced graphene oxide(CoMoO_(4)@rGO)is reported as a class of superior cathode hosts for RT Na-S batteries.The CoMoO_(4)@rGO matrix is designed to facilitate the reversible sodiation and desodiation of sulfur,considering the strong chemisorption between sulfur(and short-chain sodium sulfides)and CoMoO_(4),which alleviates the shuttle effect of sodium sulfides and accelerates the electrochemical reaction rate at RT.The obtained S/CoMoO_(4)@rGO cathode with~52%S loading exhibits a high capacity of520.1 mA h g^(-1)after 100 cycles at 0.1 A g^(-1).Moreover,an enhanced long-term performance at high current densities(212.2 mA h g^(-1)at 4 A g^(-1)over 1000 cycles)with high Coulombic efficiency(~100%)is also achieved.This work demonstrates a novel multifunctional additive for RT Na-S battery cathodes,which is expected to promote the long-waited development towards practical applications of RT Na-S batteries.Xin Ye Sainan Luo Zhiqi Li Jiafeng Ruan Yuepeng Pang Junhe Yang John Wang Shiyou Zheng 2023Journal of Energy Chemistry2023,,11:1
