1Biosorption mechanisms involved in immobilization of soil Pb by Bacillus subtilis DBM in a multi-metal-contaminated soil显示文摘Mechanisms of soil Pb immobilization by Bacillus subtilis DBM, a bacterial strain isolated from a heavy-metal-contaminated soil, were investigated. Adsorption and desorption experiments with living bacterial cells as well as dead cells revealed that both extracellular adsorption and intracellular accumulation were involved in the Pb2+removal from the liquid phase. Of the sequestered Pb(II), 8.5% was held by physical entrapment within the cell wall, 43.3% was held by ion-exchange, 9.7% was complexed with cell surface functional groups or precipitated on the cell surface, and 38.5% was intracellularly accumulated.Complexation of Pb2+with carboxyl, hydroxyl, carbonyl, amido, and phosphate groups was demonstrated by Fourier transform infrared spectroscopic analysis. Precipitates of Pb5(PO4)3OH, Pb5(PO4)3Cl and Pb10(PO4)6(OH)2that formed on the cell surface during the biosorption process were identified by X-ray diffraction analysis. Transmission electron microscopy–energy dispersive spectroscopic analysis confirmed the presence of the Pb(II)precipitates and that Pb(II) could be sequestered both extracellularly and intracellularly.Incubation with B. subtilis DBM significantly decreased the amount of the weak-acid-soluble Pb fraction in a heavy-metal-contaminated soil, resulting in a reduction in Pb bioavailability, but increased the amount of its organic-matter-bound fraction by 71%. The ability of B.subtilis DBM to reduce the bioavailability of soil Pb makes it potentially useful for bacteria-assisted phytostabilization of multi-heavy-metal-contaminated soil.Jun Bai Xiuhong Yang Ruiying Du Yanmei Chen Shizhong Wang Rongliang Qiu 2014Journal of Environmental Sciences2014,26,10:22
2Heavy metal (Pb,Zn) uptake and chemical changes in rhizosphere soils of four wetland plants with different radial oxygen loss显示文摘Lead and Zn uptake and chemical changes in rhizosphere soils of four emergent-rooted wetland plants;Aneilema bracteatum,Cyperus alternifolius,Ludwigia hyssopifolia and Veronica serpyllifolia were investigated by two experiments:(1) rhizobag filled with 'clean' or metal-contaminated soil for analysis of Pb and Zn in plants and rhizosphere soils;and (2) applied deoxygenated solution for analyzing their rates of radial oxygen loss (ROL).The results showed that the wetland plants with different ROL rates had significant effects on the mobility and chemical forms of Pb and Zn in rhizosphere under flooded conditions.These effects were varied with different metal elements and metal concentrations in the soils.Lead mobility in rhizosphere of the four plants both in the 'clean' and contaminated soils was decreased,while Zn mobility was increased in the rhizosphere of the 'clean' soil,but decreased in the contaminated soil.Among the four plants,V.serpyllifolia,with the highest ROL,formed the highest degree of Fe plaque on the root surface,immobilized more Zn in Fe plaque,and has the highest effects on the changes of Zn form (EXC-Zn) in rhizosphere under both 'clean' and contaminated soil conditions.These results suggested that ROL of wetland plants could play an important role in Fe plaque formation and mobility and chemical changes of metals in rhizosphere soil under flood conditions.Junxing Yang Zuoluo Ma Zhihong Ye Xueyan Guo Rongliang Qiu 2010Journal of Environmental Sciences2010,22,5:11
3Soil water repellency and influencing factors of Nitraria tangutorun nebkhas at different succession stages显示文摘Soil water repellency(WR) is an important physical characteristic of soil surface. It is capable of largely influencing the hydrological and geomorphological processes of soil, as well as affecting the ecological processes of plants, such as growth and seed germination, and has thus been a hot topic in recent research around the world. In this paper, the capillary rise method was used to study the soil WR characteristics of Nitraria tangutorun nebkhas. Soil water repellencies at different succession stages of Nitraria tangutorun were investigated, and the relationships between soil WR and soil organic matter, total N, and total P, soil texture, pH, and concentrations of CO3 2-, HCO3-, Cl-, SO4 2-, Na+, K+, Ca2+and Mg2+were discussed. Soil WR may be demonstrated at the following nebkhas dune evolvement stages: extremely degraded>degraded>stabilized>well developed>newly developed>quick sand. Apart from some soil at the bottom, the WR of other soils(crest and slope of dune) was found to be largest at the topsoil, and decreased as the soil depth increased. The results showed that multiple factors affected soil WR characteristics, e.g. WR increased significantly as the contents of soil organic matter and total N increased, but did not change as the total P content increased. Soil texture was a key factor affecting soil WR; soil WR increased significantly as clay content increased, and decreased significantly as sand content increased. Low pH was shown to be more suitable for the occurrence of soil WR. Four cations(Ca2+, Mg2+, K+and Na+) and two anions(Cl-and SO4 2-) enhanced soil WR, while CO3 2-decreased it. HCO3-did not show any observable effect. Finally, we established a best-fit general linear model(GLM) between soil-air-water contact angle(CA) and influencing factors(CA=5.606 sand+6.496(clay and silt)–2.353 pH+470.089 CO3 2-+11.346 Na+–407.707 Cl-–14.245 SO4 2-+0.734 total N–519.521). It was concluded that all soils contain subcritical WR(0°HaoTian YANG XinRong LI LiChao LIU YanHong GAO Gang LI RongLiang JIA 2014Journal of Arid Land2014,6,3:9
4The effects of extreme rainfall events on carbon release from biological soil crusts covered soil in fixed sand dunes in the Tengger Desert, northern China显示文摘In May to August of 2011, we assessed the effects of extreme rainfall (quantity and intensity) events on the carbon release from soils covered by different types of biological soil crusts (BSCs) in fixed sand dunes in the Tengger Desert, northern China. A Li-6400-09 Soil Chamber was used to measure the respiration rates of the BSCs immediately after the rainfall stopped, and continued until the respiration rates of the BSCs returned to the pre-rainfall basal rate. Our results showed that almost immediately after extreme rainfall events the respiration rates of algae crust and mixed crust were significantly inhibited, but moss crust was not significantly affected. The respiration rates of algae crust, mixed crust, and moss crust in extreme rainfall quantity and intensity events were, respectively, 0.12 and 0.41 μmolCO 2 /(m 2 ·s), 0.10 and 0.45 μmolCO 2 /(m 2 ·s), 0.83 and 1.69 μmolCO 2 /(m 2 ·s). Our study indicated that moss crust in the advanced succession stage can well adapt to extreme rainfall events in the short term.Yang Zhao XinRong Li ZhiShan Zhang RongLiang Jia YiGang Hu Peng Zhang 2013Research in Cold and Arid Regions2013,5,2:4
5Upcycling biomass waste into Fe single atom catalysts for pollutant control显示文摘Contaminants of heavy metals and antibiotics, which are frequently detected in water, soil and food chains with increasing prevalence in our current society, can cause potential harm to human health and disrupt human ecosystem irreversibly. Herein, we have successfully utilized biomass waste ferns contaminated by iron mines, to fabricate a first-of-its-kind high-performance class of Fe single-atom catalysts(FeSAC) by a facile pyrolysis. The optimal FeSAC-800 shows an excellent efficiency in the fastphotocatalytic degradation of six types of quinolone antibiotics(e.g., norfloxacin, levofloxacin, ciprofloxacin, enrofloxacin, lomefloxacin, flumequine) in 1 h under the simulated natural light irradiation. Based on advanced characterization, a well-defined structure of FeN_(4), confined in the porous carbon is elaborated for the FeSAC-800. Mechanism of the photodegradation is via a Fenton-like oxidation process whereas the reactive oxygen species play a key role. These findings open a new avenue for efficient, sustainable utilization of biomass waste in pollutant control.Xin Li Kang Hu Yizhe Huang Qingqing Gu Yuwen Chen Bing Yang Rongliang Qiu Wenhao Luo Bert M.Weckhuysen Kai Yan 2022Journal of Energy Chemistry2022,31,6:3
6Characteristics of soil water repellency after sand dune stabilization in the Tengger Desert显示文摘Soil water repellency (SWR) is one of the most important physical properties of soils found all over the world, and it may have significant effects on the eco-hydrological processes of land ecosystems. In this study, the Capillary Rise Method was used to measure the SWR in the artificial vegetation area in Shapotou, located in the southeast area of the Tengger Desert, Ningxia Province of western China. The variation of the soil water repellency among different minor topographies, different depths and different particle sizes was analyzed. The results of the study indicate that the SWR shows distinct changes with vegetation restoration, and it increases with an increase in the period of dune stabilization. In the same vegetation area, the SWR of soils in inter-dune depressions or windward slopes is slightly greater than that in crest or leeward slopes. The SWR of 0-3 cm topsoil is significantly greater than that in the 3-6 cm soil layer. The SWR decreases with an increase in grain size and the differences among the SWRs of different sieved soil fractions are found to be significant. There is also a significantly positive correlation between the SWR and the proportion of soils with grain sizes of 0-0.05, 0.05-0.01 and 0.01-0.15 mm, and a significantly negative correlation between the SWR and the propotion of soils with grain sizes exceeding 0.15 mm. The increase of SWR in revegetation areas may depend on the continuous depositing of atmospheric dust on the stabilized dune surface as well as the formation of biological soil crusts, especially on the formation of algal and lichen crusts. Enhanced SWR influences the effectiveness of water use of sand plants inhabiting the sand dunes.HaoTian Yang LiChao Liu XinRong Li YongPing Wei YanHong Gao XiaoJun Li RongLiang Jia Lei Huang 2012Research in Cold and Arid Regions2012,4,5:2
7Ultrathin, Lightweight, and Flexible CNT Buckypaper Enhanced Using MXenes for Electromagnetic Interference Shielding显示文摘Lightweight,flexibility,and low thickness are urgent requirements for next-generation high-performance electromagnetic interference(EMI)shielding materials for catering to the demand for smart and wearable electronic devices.Although several efforts have focused on constructing porous and flexible conductive films or aerogels,few studies have achieved a balance in terms of density,thickness,flexibility,and EMI shielding effectiveness(SE).Herein,an ultrathin,lightweight,and flexible carbon nanotube(CNT)buckypaper enhanced using MXenes(Ti3C2Tx)for high-performance EMI shielding is synthesized through a facile electrophoretic deposition process.The obtained Ti3C2Tx@CNT hybrid buckypaper exhibits an outstanding EMI SE of 60.5 dB in the X-band at 100μm.The hybrid buckypaper with an MXene content of 49.4 wt%exhibits an EMI SE of 50.4 dB in the X-band with a thickness of only 15μm,which is 105%higher than that of pristine CNT buckypaper.Furthermore,an average specific SE value of 5.7×10^(4) dB cm^(2) g^(−1) is exhibited in the 5-μm hybrid buckypaper.Thus,this assembly process proves promising for the construction of ultrathin,flexible,and high-performance EMI shielding films for application in electronic devices and wireless communications.Rongliang Yang Xuchun Gui Li Yao Qingmei Hu Leilei Yang Hao Zhang Yongtao Yao Hui Mei Zikang Tang 2021Nano-Micro Letters2021,13,4:2
8Molecular dynamics simulations of the hydration of poly(vinyl methyl ether):Hydrogen bonds and quasi-hydrogen bonds显示文摘Atomistic detailed hydration structures of poly(vinyl methyl ether)(PVME) have been investigated by molecular dynamics simulations under 300 K at various concentrations. Both radial distribution functions and the distance distributions between donors and acceptors in hydrogen bonds show that the hydrogen bonds between the polymer and water are shorter by 0.005 nm than those between water molecules. The Quasi-hydrogen bonds take only 7.2% of the van der Waals interaction pairs. It was found the hydrogen bonds are not evenly distributed along the polymer chain,and there still exists a significant amount(10%) of ether oxygen atoms that are not hydrogen bonded to water at a concentration as low as 3.3%. This shows that in polymer solutions close contacts occur not only between polymer chains but also between chain segments within the polymer,which leads to inefficient contacts between ether oxygen atoms and water molecules. Variation of the quasi-hydrogen bonds with the concentration is similar to that of hydrogen bonds,but the ratio of the repeat units forming quasi-hydrogen bonds to those forming hydrogen bonds approaches 0.2. A transition was found in the demixing enthalpy at around 30% measured by dynamic testing differential scanning calorimetry(DTDSC) for aqueous solutions of a mono-dispersed low molecular weight PVME,which can be related to the transition of the fractions of hydrogen bonds and quasi-hydrogen bonds at ~27%. The transition of the fractions of hydrogen bonds and quasi-hydrogen bonds at ~27% can be used to explain the demixing enthalpy transition at 30% at a molecular scale. In addition,at the concentration of 86%,each ether oxygen atom bonded with water is assigned 1.56 water molecules on average,and 'free' water molecules emerge at the concentration of around 54%.WU RongLiang JI Qing KONG Bin YANG XiaoZhen 2008Science China Chemistry2008,51,8:2

14Immunogenicity of multi-epitope-based vaccine candidates administered with the adjuvant Gp96 against rabies显示文摘Rabies, a zoonotic disease, causes > 55,000 human deaths globally and results in at least 500 million dollars in losses every year. The currently available rabies vaccines are mainly inactivated and attenuated vaccines, which have been linked with clinical diseases in animals. Thus, a rabies vaccine with high safety and efficacy is urgently needed. Peptide vaccines are known for their low cost, simple production procedures and high safety. Therefore, in this study, we examined the efficacy of multi-epitope-based vaccine candidates against rabies virus. The ability of various peptides to induce epitope-specific responses was examined, and the two peptides that possessed the highest antigenicity and conservation, i.e., AR16 and h PAB, were coated with adjuvant canineGp96 and used to prepare vaccines. The peptides were prepared as an emulsion of oil in water(O/W) to create three batches of bivalent vaccine products. The vaccine candidates possessed high safety. Virus neutralizing antibodies were detected on the day 14 after the first immunization in mice and beagles, reaching 5–6 IU/m L in mice and 7–9 IU/m L in beagles by day 28. The protective efficacy of the vaccine candidates was about 70%–80% in mice challenged by a virulent strain of rabies virus. Thus, a novel multi-epitope-based rabies vaccine with Gp96 as an adjuvant was developed and validated in mice and dogs. Our results suggest that synthetic peptides hold promise for the development of novel vaccines against rabies.Yange Niu Ye Liu Limin Yang Hongren Qu Jingyi Zhao Rongliang Hu Jing Li Wenjun Liu 2016Virologica Sinica2016,31,2:1
15Direct stamping multifunctional tactile sensor for pressure and temperature sensing显示文摘Flexible and wearable sensors have broad application prospects in health monitoring and artificial intelligence.Many different single-functional sensing devices have been developed in recent years,such as pressure sensors and temperature sensors.However,it is still a great challenge to design and fabricate tactile sensors with multiple sensing functions.Herein,we propose a simple direct stamping method for the fabrication of multifunctional tactile sensors.It can detect pressure and temperature stimuli signals simultaneously.This pressure/temperature sensor possesses high sensitivity(0.67 kPa^(-1)),large linear range(0.75-5 kPa),and fast response speed(15.6 ms)in pressure sensing.It also has a high temperature sensitivity(1.41%/℃)and great linearity(0.99)for temperature sensing in the range of-30 to 30℃.All these excellent performances indicate that this pressure/temperature sensor has great potential in applications for artificial intelligence and health monitoring.Binghao Liang Bingfang Huang Junkai He Rongliang Yang Chengchun Zhao Bo-Ru Yang Anyuan Cao Zikang Tang Xuchun Gui 2022Nano Research2022,15,4:1
16Nanopore sequencing of African swine fever virus显示文摘Dear Editor,African swine fever(ASF)is one of the most pathogenic viral diseases in pigs caused by African swine fever virus(ASFV).The fatality rate is almost 100%,which brings huge economic losses to the hog industry in countries with epiepidemics(Galindo and Alonso,2017).China was the first Asian country to have an ASF epidemic,and it spread quickly across the country after the first epidemic was re・ported in August 2018(Ge et al.,2018).After that,Mongolia,Vietnam,Cambodia and North Korea also reported on the ASF epidemic in succession(OIE,2019).Lijia Jia Mengwei Jiang Ke Wu Juefu Hu Yang Wang Weipeng Quan Mengchan Hao Haizhou Liu Hongping Wei Wenhui Fan Wenjun Liu Rongliang Hu Depeng Wang Jing Li Jianjun Chen Di Liu 2020Science China(Life Sciences)2020,63,1:0
17Amorphous gallium oxide homojunction-based optoelectronic synapse for multi-functional signal processing显示文摘In the era of accelerated development in artificial intelligence as well as explosive growth of information and data throughput,underlying hardware devices that can integrate perception and memory while simultaneously offering the bene-fits of low power consumption and high transmission rates are particularly valuable.Neuromorphic devices inspired by the human brain are considered to be one of the most promising successors to the efficient in-sensory process.In this paper,a homojunction-based multi-functional optoelectronic synapse(MFOS)is proposed and testified.It enables a series of basic electri-cal synaptic plasticity,including paired-pulse facilitation/depression(PPF/PPD)and long-term promotion/depression(LTP/LTD).In addition,the synaptic behaviors induced by electrical signals could be instead achieved through optical signals,where its sen-sitivity to optical frequency allows the MFOS to simulate high-pass filtering applications in situ and the perception capability integrated into memory endows it with the information acquisition and processing functions as a visual system.Meanwhile,the MFOS exhibits its performances of associative learning and logic gates following the illumination with two different wave-lengths.As a result,the proposed MFOS offers a solution for the realization of intelligent visual system and bionic electronic eye,and will provide more diverse application scenarios for future neuromorphic computing.Rongliang Li Yonghui Lin Yang Li Song Gao Wenjing Yue Hao Kan Chunwei Zhang Guozhen Shen 2023Journal of Semiconductors2023,44,7:0
18Controlling sulfurization of 2D Mo_(2)C crystal for Mo_(2)C/MoS_(2)-based memristor and artificial synapse显示文摘Owing to the conductance-adjustable performance,the emerging two-terminal memristors are promising candidates for artificial synapses and brain-spired neuromorphic computing.Although memristors based on molybdenum disulfide(MoS_(2))have displayed outstanding performance,such as thermal stability and high energy efficiency,reports on memristors based on MoS_(2) as the functional layer to simulate synaptic behavior are limited.Herein,a homologous Mo_(2)C/MoS_(2)-based memristor is prepared by partially sulfuring two-dimensional Mo_(2)C crystal.The memristor shows good stability,excellent retention(~104 s)and endurance(>100 cycles),and a high ON/OFF ratio(>10^(3)).Moreover,for comprehensively mimicking biological synapses,the essential synaptic functions of the device are systematically analyzed,including paired-pulse facilitation(PPF),short-term plasticity(STP),long-term plasticity(LTP),long-term depression(LTD),and the transitions from STP to LTP.Notably,this artificial synapse could keep a highlevel stable memory for a long time(60 s)after repeated stimulation.These results prove that our device is highly desirable for biological synapses,which show great potential for application in future high-density storage and neuromorphic computing systems.Xin Tang Leilei Yang Junhua Huang Wenjun Chen Baohua Li Shaodian Yang Rongliang Yang Zhiping Zeng Zikang Tang Xuchun Gui 2022npj Flexible Electronics2022,6,1:0
19Amplitude of peroneal compound motor action potential increases in type 2 diabetes with thyroid autoimmunity显示文摘Dear Editor,Diabetic peripheral neuropathy(DPN)is a frequently occurring complication of diabetes.DPN is diagnosed on the basis of findings of neural electrophysiological study,such as the nerve conduction study(NCS).The most common NCS manifestations of DPN include slow velocity,prolonged latency,and decreased amplitude.Risk factors for DPN include age,hyperglycemia,dyslipidemia,smoking,atherosclerotic cardiovascular disease,peripheral arterial disease,diabetic nephropathy,and diabetic retinopathy.Fanfan Zhu Boren Jiang Rongliang Ren Lizhen Yang 2018Science China(Life Sciences)2018,61,8:0
20Identification of lipid metabolism-related genes as prognostic indicators in papillary thyroid cancer显示文摘Lipid metabolism plays important roles not only in the structural basis and energy supply of healthy cells but also in the oncogenesis and progression of cancers.In this study,we investigated the prognostic value of lipid metabolism-related genes in papillary thyroid cancer(PTC).The recurrence predictive gene signature was developed and internally and externally validated based on PTC datasets including The Cancer Genome Atlas(TCGA)and GSE33630 datasets.Univariate,LASSO,and multivariate Cox regression analysis were applied to assess prognostic genes and build the prognostic gene signature.The expression profiles of prognostic genes were further determined by immunohistochemistry of tissue microarray using in-house cohorts,which enrolled 97 patients.Kaplan–Meier curve,time-dependent receiver operating characteristic curve,nomogram,and decision curve analyses were used to assess the performance of the gene signature.We identified four recurrence-related genes,PDZK1IP1,TMC3,LRP2 and KCNJ13,and established a four-gene signature recurrence risk model.The expression profiles of the four genes in the TCGA and in-house cohort indicated that stage T1/T2 PTC and locally advanced PTC exhibit notable associations not only with clinicopathological parameters but also with recurrence.Calibration analysis plots indicate the excellent predictive performance of the prognostic nomogram constructed based on the gene signature.Single-sample gene set enrichment analysis showed that high-risk cases exhibit changes in several important tumorigenesis-related pathways,such as the intestinal immune network and the p53 and Hedgehog signaling pathways.Our results indicate that lipid metabolism-related gene profiling represents a potential marker for prognosis and treatment decisions for PTC patients.Shishuai Wen Yi Luo Weili Wu Tingting Zhang Yichen Yang Qinghai Ji Yijun Wu Rongliang Shi Ben Ma Midie Xu Ning Qu 2021Acta Biochimica et Biophysica Sinica2021,53,12:0
