| 1 | Heavy metal phytoextraction by Sedum alfredii is affected by continual clipping and phosphorus fertilization amendment显示文摘Improving the efficacy of phytoextraction is critical for its successful application in metal contaminated soils. Mineral nutrition affects plant growth and metal absorption and subsequently the accumulation of heavy metal through hyper-accumulator plants. This study assessed the effects of di-hydrogen phosphates (KH2PO4, Ca(H2PO4)2, NaH2PO4 and NH4H2PO4) application at three levels (22, 88 and 352 mg P/kg soil) on Sedum alfredii growth and metal uptake by three consecutive harvests on aged and Zn/Cd combined contaminated paddy soil. The addition of phosphates (P) significantly increased the amount of Zn taken up by S. alfredii due to increased shoot Zn concentration and dry matter yield (DMY) (P < 0.05). The highest phytoextraction of Zn and Cd was observed in KH2PO4 and NH4H2PO4 treatment at 352 mg P/kg soil. The amount of Zn removed by phytoextraction increased in the order of 1st clipping < 2nd clipping < 3rd clipping, and for Cd extraction the order was 2nd clipping < 1st clipping < 3rd clipping. These results indicate that the application of P fertilizers coupled with multiple cuttings can enhance the removal of Zn and Cd from contaminated soils by S. alfredii, thus shortening the time needed for accomplishing remediation goals. | Huagang Huang Tingqiang Li D.K.Gupta Zhenli He Xiao-e Yang Bingnan Ni Mao Li | 2012 | Journal of Environmental Sciences2012，24，3： | 4 |
| 2 | Berlin Green Framework‑Based Gas Sensor for Room‑Temperature and High‑Selectivity Detection of Ammonia显示文摘Ammonia detection possesses great potential in atmosphere environmental protection,agriculture,industry,and rapid medical diagnosis.However,it still remains a great challenge to balance the sensitivity,selectivity,working temperature,and response/recovery speed.In this work,Berlin green(BG)framework is demonstrated as a highly promising sensing material for ammonia detection by both density functional theory simulation and experimental gas sensing investigation.Vacancy in BG framework offers abundant active sites for ammonia absorption,and the absorbed ammonia transfers sufficient electron to BG,arousing remarkable enhancement of resistance.Pristine BG framework shows remarkable response to ammonia at 50–110°C with the highest response at 80°C,which is jointly influenced by ammonia’s absorption onto BG surface and insertion into BG lattice.The sensing performance of BG can hardly be achieved at room temperature due to its high resistance.Introduction of conductive Ti3CN MXene overcomes the high resistance of pure BG framework,and the simply prepared BG/Ti3CN mixture shows high selectivity to ammonia at room temperature with satisfying response/recovery speed. | Tingqiang Yang Lingfeng Gao Wenxuan Wang Jianlong Kang Guanghui Zhao Delong Li Wen Chen Han Zhang | 2021 | Nano-Micro Letters2021，13，4： | 2 |
| 3 | Effect of elevated CO_2 concentration on photosynthetic characteristics of hyperaccumulator Sedum alfredii under cadmium stress显示文摘The combined effects of elevated CO_2 and cadmium(Cd) on photosynthetic rate,chlorophyll fluorescence and Cd accumulation in hyperaccumulator Sedum alfredii Hance were investigated to predict plant growth under Cd stress with rising atmospheric CO_2 concentration.Both pot and hydroponic experiments were conducted and the plants were grown under ambient(350 μL L^(-1)) or elevated(800 μL L^(-1))CO_2.Elevated CO_2 significantly(P< 0.05) increased Pn(105%-149%),Pn_(max)(38.8%-63.0%) and AQY(20.0%-34.8%) of S.alfredii in all the Cd treatments,but reduced chlorophyll concentration,dark respiration and photorespiration.After 10 days growth in medium with 50μM Cd under elevated CO_2,PSII activities were significantly enhanced(P < 0.05) with Pm,Fv/Fm,Φ(Ⅱ) and qP increased by 66.1%,7.5%,19.5%and 16.4%,respectively,as compared with ambient-grown plants.Total Cd uptake in shoot of S.alfredii grown under elevated CO_2 was increased by 44.1%-48.5%,which was positively correlated with the increase in Pn.These results indicate that elevated CO_2 promoted the growth of 5.alfredii due to increased photosynthetic carbon uptake rate and photosynthetic lightuse efficiency,and showed great potential to improve the phytoextraction of Cd by S.alfredii. | Tingqiang Li Qi Tao Zhenzhen Di Fan Lu Xiaoe Yang | 2015 | Journal of Integrative Plant Biology2015，57，7： | 2 |

| 9 | Probabilistic stability analysis of Bazimen landslide with monitored rainfall data and water level fluctuations in Three Gorges Reservoir, China显示文摘Landslide is a common geological hazard in reservoir areas and may cause great damage to local residents’life and property.It is widely accepted that rainfall and periodic variation of water level are the two main factors triggering reservoir landslides.In this study,the Bazimen landslide located in the Three Gorges Reservoir(TGR)was back-analyzed as a case study.Based on the statistical features of the last 3-year monitored data and field instrumentations,the landslide susceptibility in an annual cycle and four representative periods was investigated via the deterministic and probabilistic analysis,respectively.The results indicate that the fluctuation of the reservoir water level plays a pivotal role in inducing slope failures,for the minimum stability coefficient occurs at the rapid decline period of water level.The probabilistic analysis results reveal that the initial sliding surface is the most important area influencing the occurrence of landslide,compared with other parts in the landslide.The seepage calculations from probabilistic analysis imply that rainfall is a relatively inferior factor affecting slope stability.This study aims to provide preliminary guidance on risk management and early warning in the TGR area. | Wengang ZHANG Libin TANG Hongrui LI Lin WANG Longfei CHENG Tingqiang ZHOU Xiang CHEN | 2020 | Frontiers of Structural and Civil Engineering2020，14，5： | 1 |
| 10 | Positive effects of applying endophytic bacteria in eggplant-Sedum intercropping system on Cd phytoremediation and vegetable production in cadmium polluted greenhouse显示文摘The combination of intercropping and phytoremediation in the remediation of cadmium contaminated soil is an emerging model in recent years,but the results of previous studies are inconsistent.In the field experiment,eggplant was intercropped with hyperaccumula-tor Sedum alfredii Hance(inoculated or not inoculated with endophytic bacteria)to study the effects of intercropping on vegetable safety production,phytoremediation efficiency of hyperaccumulator and variation of soil available nutrients.The results showed that the in-tercropping treatment had a negative effect on the growth of eggplant and Sedum,but en-dophyte SaMR12 alleviated the inhibition of intercropping on plant growth.Intercropping treatment increases the Cd concentration in edible part of eggplant to 1.34 mg/kg compared with eggplant monoculture(1.19 mg/kg).While the application of SaMR12 reduces the Cd concentration of eggplant fruit to 0.95 mg/kg and significantly promotes the Cd uptake by Sedum.What's more surprising is that compared with eggplant monocropping,the con-tent of soil available nitrogen,phosphorus and potassium in the treatment of intercropping with inoculated Sedum increased significantly.And according to the correlation analysis of various indexes of plants and soil,the Cd content of eggplant is negatively correlated with the available phosphorus and potassium in the soil,while the Cd content of Sedum is positively correlated with it,which suggested that the application of phosphorus and potas-sium fertilizers in this experimental site was beneficial to reduce Cd content in eggplant and improve Cd phytoextraction of Sedum.Therefore,in the daily production of moderately Cd-contaminated soil,intercropping eggplant with Sedum inoculated with endophytic bacteria is an excellent Phytoextraction Coupled with Agro-safe-production(PCA)pattern. | Luyao Ma Lukuan Huang Qizhen Liu Shunan Xu Zheyu Wen Shuai Qin Tingqiang Li Ying Feng | 2022 | Journal of Environmental Sciences2022，34，5： | 1 |

| 19 | Compounded chelating agent derived from fruit residue extracts effectively enhances Cd phytoextraction by Sedum alfredii显示文摘Chelating agent is known as the enhancer for metal phytoextraction;however,there is still a lack of efficient and environmentally sustainable chelators.Here,lemon residue extraction(LRE),prepared from 11 kinds of fruit wastes,was combined with N,N-bis(carboxymethyl)glutamic acid(GLDA),and tea saponin(T.S.)for the compounded plant-derived chelator(CPC),and their influences on Cd phytoextraction by the hyperaccumulator Sedum alfredii was evaluated.Among these fruits,the lemon residue extracted the most significant amount of Cd from the soil.The most effective CPC was at the volume ratio of three agents being 15:4:1(LRE:GLDA:T.S.).Compared with the deionized water,the solubility of three Cd minerals was increased by 85–256 times,and Cd speciation was substantially altered after CPC application.In the pot experiment,CPC addition caused evident increases in plant shoot biomass,Cd phytoextraction efficiency,and organic matter content compared with EDTA and nitrilotriacetic acid(NTA)application.CPC induced fewer changes in bacterial community composition compared with EDTA and had no pronounced influence on microbial biomass carbon and bacterialα-diversity,suggesting CPC had a subtle impact on the microbiological environments.Our study provides a theoretical base for the reutilization of fruit wastes and the development of environmental-friendly chelator that assists Cd phytoextraction. | Jipeng Luo Jiabin Liang Yuchao Song Xinyu Guo Youzheng Ning Nanlin Liu Heping Zhao Tingqiang Li | 2021 | Soil Ecology Letters2021，3，3： | 1 |
